    JIM P. BENGE, M.D., AND KELSEY-SEYBOLD MEDICAL GROUP,
    PLLC, Appellants
    V.
    LAUREN WILLIAMS, Appellee
    On Appeal from the 164th District Court
    Harris County, Texas
    Trial Court Case No. 2010-52657
    OPINION
    Dr. Jim Benge and his employer, Kelsey-Seybold Medical Group, PLLC,
    appeal from an adverse jury verdict finding that Dr. Benge’s medical negligence
    caused a perforation of Lauren Williams’s bowel during a hysterectomy. Dr. Benge
    and Kelsey-Seybold (collectively Dr. Benge) raise three issues challenging the
    judgment against them. First, Dr. Benge contends that Williams’s expert on the
    applicable medical standard of care was statutorily disqualified. Second, Dr. Benge
    argues that the jury charge commingled in one broad-form submission two theories
    of negligence—negligent surgical technique and negligent failure to obtain the
    patient’s informed consent—over his objection, resulting in harmful error. Third,
    Dr. Benge asserts that the trial court erred in refusing to allow periodic payment of
    future medical expenses.
    We first consider whether the trial court abused its discretion in allowing
    Williams’s expert on the standard of care to testify; we hold that it did not. We
    next consider whether the jury charge impermissibly combined valid and invalid
    theories of liability into a single liability question. Because we conclude that it did
    and that Dr. Benge preserved the error for appeal, we reverse and remand the cause
    for a new trial. As a result, we do not reach the issue of periodic payments.
    Background
    Williams brought this health care liability case following a hysterectomy.
    The hysterectomy was performed by Dr. Benge, a board-certified obstetrician and
    gynecologist who has practiced with Kelsey-Seybold since 2000. Dr. Benge was
    assisted by Dr. Lauren Giacobbe, a third-year obstetrical/gynecological resident in
    Methodist Willowbrook Hospital’s four-year residency program. It is undisputed
    that Williams’s bowel was perforated as a result of the hysterectomy.
    2
    A.    Williams’s hysterectomy, complications, and subsequent surgeries
    Dr. Benge first saw Williams, then age 39, in June 2008, two months before
    her surgery. Williams discussed her symptoms, including chronic and
    “excruciating” pain during her menstrual period. Dr. Benge diagnosed Williams
    with uterine fibroids, dysfunctional uterine bleeding, and pelvic pain. After
    consulting with Dr. Benge, Williams elected to undergo a laparoscopic-assisted
    vaginal hysterectomy (LAVH) to remove her uterus, ovaries, and fallopian tubes.
    Dr. Benge next met with Williams one week before the LAVH surgery. Dr.
    Benge discussed the procedure and presented her with written disclosure and
    consent forms that they reviewed together. The consent forms—which tracked the
    requirements imposed by the Texas Legislature—set forth surgical risks associated
    with the LAVH procedure, including, among other things, damage to the bowel,
    the injury that formed the basis for Williams’s claim. The consent forms also stated
    that Dr. Benge could use such “associates, technical assistants and other health
    care providers as [he] may deem necessary” during the surgery and that those
    assisting Dr. Benge may include “residents” who could “perform important tasks”
    during the surgery “under the supervision of a responsible physician.” Dr. Benge
    testified that during this visit he told Williams that he “would be doing the surgery
    with an assistant.” Williams disputes that contention. She testified that he did not
    tell her there would be an assistant. Although it is disputed whether Dr. Benge
    3
    mentioned using an assistant in the procedure, the parties agree that Dr. Benge did
    not tell Williams that he would be assisted by someone with no prior experience
    assisting on an LAVH procedure.
    Williams signed the consent forms and agreed in writing to proceed with the
    planned LAVH surgery. Dr. Benge performed the LAVH procedure on the
    morning of August 26, 2008, with Dr. Giacobbe assisting. While Dr. Giacobbe had
    significant experience with hysterectomies and laparoscopic surgeries, she had not
    previously assisted an LAVH surgery. Dr. Giacobbe testified that she explained to
    Dr. Benge her experience level before the surgery began and that he determined
    the tasks she would perform. She also testified that she introduced herself to
    Williams on the morning of the surgery and told Williams that she was a resident
    and was going to be “assisting” Dr. Benge with the surgery. Dr. Giacobbe did not
    identify the surgical tasks she would perform; she testified that she did not know
    those details until after the surgery began. Williams disputed Dr. Giacobbe’s
    testimony. She testified that she did not speak with Dr. Giacobbe on the morning
    of her surgery. Williams further testified that she would not have undergone the
    surgery if she had been informed that it was Dr. Giacobbe’s first time assisting an
    LAVH surgery.
    The amount of assistance provided by Dr. Giacobbe was disputed. An
    LAVH operation is divided into two parts: the laparoscopic part, followed by the
    4
    vaginal part. The post-operative report does not indicate which physician
    performed which portion of the procedure. Dr. Giacobbe testified that Dr. Benge
    remained at all times “in control of the patient’s care and directing” the surgery.
    She estimated that she performed approximately 40% of the surgery and did so
    under Dr. Benge’s direction and supervision. In a document she signed after the
    surgery that was maintained to monitor the resident’s experiences, however, she
    reported that she was “the surgeon,” which required her to perform 50% or more of
    the surgery. Dr. Benge estimated that Dr. Giacobbe performed 40% or less of the
    surgery. He testified that the standard of care is “for the attending physician to
    decide, based on [the resident’s] skill-set, what is appropriate for her to do.”
    During the laparoscopic part of the LAVH, Dr. Benge stood on the right side
    of Williams while Dr. Giacobbe stood on the left. Dr. Benge demonstrated each
    step of the operation to Dr. Giacobbe and showed her “how to use the instruments
    and what to do.” Dr. Giacobbe would then repeat the same thing on the left side—
    the side where Williams was determined to have a perforation—while Dr. Benge
    observed.
    Upon completion of the procedure, Dr. Benge examined the surgical area but
    saw no signs that Williams’s bowel had been perforated. He noted no
    complications in the post-operative report. Within hours of the surgery, Williams
    began to complain of severe pain, abdominal tenderness, and nausea. Later that
    5
    day, rectal bleeding was discovered. By the time Dr. Benge saw Williams on the
    morning following the LAVH procedure, she had a fever and was anemic,
    tachycardic, and in constant pain. According to Dr. Benge, nothing about
    Williams’s condition at that time indicated that she had a perforated bowel. He
    started her on intravenous antibiotics and ordered an x-ray of her chest to ensure
    that she did not have pneumonia. He did not see her again that day because he went
    home ill; instead, Dr. Carmen Thornton took over Williams’s care.
    Williams’s    post-operative   condition   continued    to   deteriorate:   her
    hemoglobin and hematocrit levels fell significantly, she required a multi-unit blood
    transfusion, and she experienced constant pain. Three days post-surgery, Dr.
    Thornton ordered a consultation from a gastroenterologist, who performed an
    emergency exploratory surgery that night and determined that Williams had an
    undiagnosed bowel perforation that was allowing feces from Williams’s intestines
    to leak into her abdomen. The doctors repaired the perforation, but a colostomy
    was required.
    Afterwards, she was moved to ICU and placed in a chemically-induced
    coma. Williams subsequently developed sepsis and underwent a tracheotomy. A
    mechanical ventilator was required. Williams remained comatose at the hospital
    for three weeks. She was discharged on October 1, 2008, and transferred to
    6
    Kindred Rehabilitation Hospital. When she left Kindred the next month, she
    required home health assistance and was unable to work.
    Williams had a second surgery in May 2009 in an effort to reverse the
    colostomy. This procedure could not be completed successfully; therefore, the
    colostomy was replaced with an ileostomy. Three months later, Williams had her
    third post-LAVH surgery to replace the ileostomy with another colostomy; the
    surgery was successful, but the colostomy became permanent. Williams has had
    two additional surgeries since then to address complications related to the
    colostomy.
    B.    Possible causes of Williams’s perforated bowel
    One week after Williams’s LAVH, Dr. Benge wrote an e-mail to Dr.
    Giacobbe stating his theory of how the bowel injury occurred. Specifically, he
    stated that the injury likely resulted from “an electrical arc from the BOVIE, 1 not a
    sponge stick or the weighted speculum.” 2 According to Dr. Benge, during the
    vaginal portion of the surgery, the weighted speculum was touching the area where
    the bowel perforated. Dr. Benge opined that an arc of electricity went from the
    BOVIE through the weighted speculum, causing a “thermal injury” to Williams’s
    1
    The “BOVIE” is an electrical cauterizing instrument that uses energy to cut the
    tissue or to fuse it together to stop bleeding.
    2
    A weighted speculum is a surgical tool used to hold tissue in an optimal
    location to allow the surgeon better access to the surgical area.
    7
    bowel tissue below. Even though no immediate damage to the bowel tissue was
    visible at the time of the surgery, Dr. Benge theorized at trial that an electrical arc
    from the BOVIE could have caused the inflammation, tissue breakdown, and
    bowel perforation Williams experienced. While neither Dr. Benge nor Dr.
    Giacobbe saw an electrical arc during the surgery, Dr. Benge testified that it is
    possible for an arc to pass from the BOVIE without being seen.
    Dr. Bruce Patsner, a board-certified obstetrician/gynecologist, testified as
    Williams’s medical liability expert. In his opinion, the perforation of Williams’s
    bowel occurred during the vaginal portion of the LAVH procedure and was caused
    by a surgical cut, not a thermal injury resulting from an electrical arc as Dr. Benge
    opined. Dr. Patsner testified that, based on reasonable medical probability, it was
    more likely that the less-experienced resident made the surgical error, not Dr.
    Benge.
    He opined that the “red flags” presented to Dr. Benge after the hysterectomy
    suggested operative complications that needed to be addressed. In Dr. Patsner’s
    opinion, Dr. Benge should have suspected a bowel injury and requested an
    immediate general surgical consultation not later than the day after the surgery. Dr.
    Patsner opined that, had Dr. Benge done so, Williams “wouldn’t have ended up in
    the operating room with . . . [a] septic shock catastrophe.” Based on his opinion
    that Dr. Benge failed to thoroughly or timely investigate and evaluate the source of
    8
    Williams’s post-LAVH complications, Dr. Patsner concluded that Dr. Benge
    deviated from the standard of care and proximately caused Williams’s injuries.
    The jury found in Williams’s favor and awarded damages.
    Dr. Patsner Met Statutory Qualifications
    In his first issue, Dr. Benge contends that the trial court erred by denying his
    motion to strike Dr. Patsner as an expert witness. During both the pre-trial and trial
    phases of this litigation, Dr. Benge challenged Dr. Patsner’s qualifications under
    Chapter 74 of the Civil Practice and Remedies Code. TEX. CIV. PRAC. & REM.
    CODE ANN. §§ 74.401–.403 (West 2011). Dr. Benge did not assert a substantive
    challenge to Dr. Patsner’s qualifications; rather, he focused on the temporal
    requirements of the statute. Dr. Benge argued that Dr. Patsner was not “practicing
    medicine” at the requisite points in time during the litigation, as required by
    section 74.401(a)(1). TEX. CIV. PRAC. & REM. CODE ANN. § 74.401(a)(1)
    (providing that witness may qualify as expert in health care liability suit if witness
    “is a physician who . . . is practicing medicine at the time such testimony is given
    or was practicing medicine at the time the claim arose.”). His argument is based on
    Dr. Patsner’s departure from the United States and subsequent work as a law
    professor and professor of medicine in Korea at the time of his testimony.
    9
    A.    Standards of review regarding statutory qualifications
    Each party has the burden to prove that her own expert is qualified to offer
    expert testimony at trial. Rittger v. Danos, 
    332 S.W.3d 550
    , 558–59 (Tex. App.—
    Houston [1st Dist.] 2009, no pet.). The determination of whether a witness is
    qualified to testify as an expert is left largely to the trial court’s discretion. See
    Broders v. Heise, 
    924 S.W.2d 148
    , 151 (Tex. 1996). We will not disturb the trial
    court’s determination that an expert is qualified unless the trial court abuses its
    discretion. See 
    id.
     A trial court abuses its discretion when it acts “‘without
    reference to any guiding rules or principles.’” 
    Id.
     (quoting E.I. du Pont de Nemours
    and Co., Inc. v. Robinson, 
    923 S.W.2d 549
    , 558 (Tex. 1995)); see Larson v.
    Downing, 
    197 S.W.3d 303
    , 304–05 (Tex. 2006). In close cases, we defer to the
    trial court’s resolution of expert qualifications and will not reverse its judgment.
    See Larson, 197 S.W.3d at 304.
    A challenge to an expert’s qualifications that raises an issue of statutory
    construction involves a question of law that we review de novo. Group v. Vicento,
    
    164 S.W.3d 724
    , 730 (Tex. App.—Houston [14th Dist.] 2005, pet. denied). We
    strive to ascertain and give effect to legislative intent when interpreting statutes.
    See 
    id.
     We look to the plain and common meaning of the language in the statute,
    reading the statute as a whole and not in isolation. 
    Id.
     If the meaning is
    unambiguous, we interpret it according to its terms, giving it a meaning that is
    10
    consistent with other provisions in the statute. 
    Id.
     Courts read every word as if it
    was deliberately chosen and presume that omitted words were excluded
    purposefully. 
    Id.
     We may also consider the legislative objective as well as the
    consequences of any particular construction. 
    Id.
    Dr. Benge contends that Williams’s expert, Dr. Patsner, does not meet the
    statutory qualifications to be a medical liability expert witness. We, therefore,
    review de novo the section 74.401 requirements applicable to expert medical
    testimony. See TEX. CIV. PRAC. & REM. CODE ANN. § 74.401.
    B.    Section 74.401(a) requires that Dr. Patsner was “practicing medicine”
    Section 74.401(a) establishes a threefold hurdle that a witness must
    overcome to qualify as an expert with respect to medical standards of care. TEX.
    CIV. PRAC. & REM. CODE ANN. § 74.401(a). The expert must: (1) be “practicing
    medicine” at the time the claim arose or at the time the testimony is given; (2) have
    knowledge of accepted standards of medical care for the diagnosis, care, or
    treatment of the illness, injury, or condition involved in the claim; and (3) be
    qualified on the basis of training or experience to offer an expert opinion regarding
    those accepted standards of medical care. Id. Dr. Benge challenges the first
    requirement, arguing that Dr. Patsner was not “practicing medicine” at the
    specified points in the litigation. Williams concedes that Dr. Patsner was not
    practicing medicine at the time her claim arose: he was a professor at the
    11
    University of Houston Law Center. Williams argues, instead, that Dr. Patsner’s
    work at the time of his testimony meets the statutory requirements for “practicing
    medicine.”
    “Practicing medicine” is defined as follows:
    For the purposes of this section, “practicing medicine” or “medical
    practice” includes, but is not limited to, training residents or students
    at an accredited school of medicine or osteopathy or serving as a
    consulting physician to other physicians who provide direct patient
    care, upon the request of such other physicians.
    TEX. CIV. PRAC. & REM. CODE ANN. § 74.401(b).
    Dr. Benge offers three arguments why Dr. Patsner’s work at the time he
    testified does not meet the statutory requirement that he be “practicing medicine.”
    First, he argues that Williams failed to establish that the Korean school of medicine
    with which Dr. Patsner was affiliated was “an accredited school of medicine”
    under section 74.401(b). Second, he argues that Williams offered no evidence that
    any of the Korean physicians with whom Dr. Patsner was consulting at the time of
    his testimony meets the statutory definition of a “physician” under section
    74.401(g), which requires that the individual be licensed to practice medicine in a
    state within the United States or have graduated from a medical school with
    particular accreditations. See § 74.401(g). 3 Third, he argues that, to the extent the
    3
    In this subchapter, “physician” means a person who is:
    (1) licensed to practice medicine in one or more states in the United States; or
    12
    phrase “practicing medicine” is not limited to the two specifically enumerated
    definitions listed in section 74.401(b), the phrase nevertheless requires Dr. Patsner
    to have actually “examined [or] admitted” patients, and Williams offered no
    evidence that Dr. Patsner was examining or admitting patients in Korea or
    elsewhere at the relevant time.
    We conclude that the statutory definition of “practicing medicine” provides
    a nonexclusive list of activities that qualify an expert to testify and further
    conclude that Dr. Patsner’s work at the time of his testimony qualifies as
    “practicing medicine.” To assist in explaining our holding, we turn first to Dr.
    Patsner’s medical background.
    1.      Dr. Patsner’s medical background
    Dr. Patsner’s professional background includes private medical practice,
    teaching positions at medical schools and affiliated hospitals, government service,
    and teaching positions at law schools. He has worked both in the United States
    and abroad.
    (2) a graduate of a medical school accredited by the Liaison Committee on
    Medical Education or the American Osteopathic Association only if
    testifying as a defendant and that testimony relates to that defendant’s
    standard of care, the alleged departure from that standard of care, or the
    causal relationship between the alleged departure from that standard of care
    and the injury, harm, or damages claimed.
    TEX. CIV. PRAC. & REM. CODE ANN. § 74.401(g) (West 2011).
    13
    Dr. Patsner is licensed to practice medicine in three states and is board-
    certified   in   obstetrics/gynecology   with   a   sub-specialty   certification   in
    gynecological oncology. He graduated from Baylor College of Medicine in 1979.
    He completed his residency in obstetrics and gynecology at the Beth Israel Medical
    Center at Harvard Medical School. He also completed a fellowship in
    gynecological oncology in 1985 at the Roswell Park Memorial Institute.
    After numerous years teaching at medical schools and working in private
    practice, Dr. Patsner attended law school. Afterwards, he was a senior medical
    officer at the Food and Drug Administration in Washington, D.C., for several years
    and served as the FDA’s representative to the Gynecology Practice Committee of
    the American College of Obstetricians and Gynecologists.
    In 2007, Dr. Patsner returned to Houston to teach at the University of
    Houston Law Center. He also began working as an Associate Professor and
    Director of Colposcopy and Preinvasive Disease in the Department of Obstetrics
    and Gynecology at Houston’s Baylor College of Medicine. In connection with this
    position, he received a Temporary Faculty License which permitted him to practice
    at a limited location even though he did not have a state-wide Texas medical
    license. He saw patients at Baylor for approximately one and one-half years while
    also teaching medicine-related law classes at the University of Houston Law
    Center. At Baylor, he also taught medical students and residents in obstetrics and
    14
    gynecology and was directly involved in resident teaching conferences to discuss
    the best methods for performing gynecologic surgery. His affiliation with Baylor
    ended July 1, 2011.
    Though the exact timing is unclear, Dr. Patsner testified that he also was the
    Assistant Director of Gynecology Oncology Service at Ben Taub Hospital and
    Harris County Hospital District until he “left Houston” in 2011 for Korea. In this
    position, he was responsible for teaching medical students and residents in
    obstetrics/gynecology and fellows in oncology at Ben Taub. He was one of three
    board-certified gynecological cancer surgeons; he selected and scheduled which of
    the three would perform various procedures, based on their comparative abilities.
    He also was one of four attending physicians running gynecological oncology
    clinics at Ben Taub, where he oversaw Ben Taub’s “inpatient pre- and post-
    operative care of surgical patients on gynecological oncology . . . on an every-
    other-week basis.” He ran four clinics a week, seeing patients with preinvasive
    disease, benign gynecological issues, and gynecological oncology problems.
    Dr. Patsner has over 120 peer-reviewed publications. For the majority of
    those publications, he is the primary author. Additionally, he was on the editorial
    board for two medical journals and a reviewer for other journals.
    In June 2011—six months before the trial of this case—Dr. Patsner ended
    his academic appointment at Baylor 2011 and began working in Seoul, South
    15
    Korea, on a three-year contract. He held two positions in Seoul: (1) Adjunct
    Clinical Professor of Obstetrics and Gynecology at Severance Hospital, Yonsei
    College of Medicine, and (2) full-time tenure-track Professor of Law and Director
    of Health Law and Policy at Yonsei Law School, Yonsei University. As an adjunct
    professor at Yonsei College of Medicine, he trained medical students, residents,
    and fellows in gynecology and gynecologic oncology and was “heavily involved”
    in their instruction. Furthermore, he would “directly teach medical students,
    residents in Obstetrics-Gynecology, and fellows in Gynecologic Oncology and
    Minimally Invasive Surgery at Yonsei Medical School/Severance University
    Hospital.” He testified that his work at the Yonsei medical school was “the same
    stuff I’ve been doing since 1983.”
    Additionally, while in Korea, Dr. Patsner “regularly lecture[d] on benign
    gynecology and gynecological oncology topics at University Hospital teaching
    conferences, and [was] an active participant in the Gynecological Oncology Tumor
    Board at Yonsei Medical School.” Dr. Patsner attended gynecology and
    gynecological oncology patient-care conferences, during which pre-operative
    patients were discussed, and was “an active participant” at monthly surgical
    morbidity and mortality conferences at the medical school. He stated that “[a]t all
    of these conferences” he and other faculty members would “make patient care
    recommendations,     which     include[d]    surgical   and    overall   treatment
    16
    recommendations.” According to Dr. Patsner, these discussions focused on the
    “selection of surgical procedures, route of surgery (open, laparoscopic, vaginal), as
    well as intense and focused discussions on anticipation of operative complications,
    proper techniques for recognition of surgical complications, and management of
    same.”
    At the time of trial, Dr. Patsner also had an ongoing affiliation with Baylor
    College of Medicine and the National Institutes of Health. He explained, “[W]e’re
    still doing research. I still have my name on NIH grants at Baylor in their genetics
    and ovarian cancer laboratory. In fact, I’m meeting with them tomorrow, unless
    I’m here . . . .”
    Though in Korea, Dr. Patsner continued to maintain his medical licenses in
    several states in the United States, allowing him to be an attending physician,
    order tests, and write prescriptions. He did not, however, have staff privileges at
    any hospital at the time he testified; therefore, he could not admit a patient to a
    hospital.
    He characterized his work at the time of trial as follows: “I’m still very
    active in obstetrics and gynecology even though I also am a law professor” in
    Korea. “I’ve worked with residents in clinic and in the operating room my entire
    career, which I guess now is—it’s 32 years.” Regarding hysterectomies
    specifically, Dr. Patsner testified in his deposition—which the trial court had
    17
    before it—that he had performed and taught LAVH-related techniques
    “continuously since the early 1990s, and [has] lectured at the medical student,
    resident, fellow, and attending level on this subject and related subjects (care of the
    surgical patient, management of complications) since that time as well.” He
    testified that he was the first person in the United States to incorporate the use of a
    new stapler design in a cervical cancer hysterectomy. In his expert report—which
    was also before the trial court—Dr. Patsner estimated that he had directly
    performed or first-assisted 450 laparoscopic hysterectomies and more than 6,000
    abdominal or vaginal hysterectomies during his career.
    Dr. Patsner testified at trial that he was leaving in one week to take a
    surgical team to Honduras for a two-week visit, focused on women’s cancer,
    during which he would be teaching medical students, residents, and surgical
    fellows; it would be “hands-on.” Although Dr. Patsner agreed at trial that he had
    not performed an LAVH since 1999, he testified that he had worked in operating
    rooms as recently as two months before trial in Taiwan.
    The question, then, is whether Dr. Patsner’s work at the time of his
    testimony was “practicing medicine” within the meaning of section 74.401, such
    that Dr. Patsner could qualify as a medical expert and opine whether Dr. Benge
    was negligent in the medical care of Williams. See TEX. CIV. PRAC. & REM. CODE
    18
    ANN. §§ 74.401–.403 (concerning qualifications of expert in medical liability
    case).
    2.    What it means to “practice medicine”
    The qualifications required to testify as an expert in a health care liability
    suit are found in Chapter 74 of the Civil Practice and Remedies Code. TEX. CIV.
    PRAC. & REM. CODE ANN. §§ 74.401–.403. Whether an individual is qualified to
    provide expert testimony is a question of law to the extent that it involves a
    question of statutory construction. Vicento, 
    164 S.W.3d at
    729–30.
    Dr. Benge argues that Dr. Patsner’s work in Korea does not qualify as
    “practicing medicine” because he neither examined nor admitted patients to
    hospitals there. Williams responds that Dr. Patsner’s work, viewed in its entirety,
    meets the general, commonly accepted understanding of the term “practicing
    medicine” sufficient to meet the statutory requirement that he be practicing
    medicine at the time of his testimony. We agree.
    3.    Giving meaning to phrase “includes, but is not limited to”
    “Practicing medicine” is statutorily defined. TEX. CIV. PRAC. & REM. CODE
    ANN. § 74.401(b). It “includes, but is not limited to,” training residents and
    medical students and serving as a consulting physician to other physicians. Id. The
    term “includes” is not defined in Chapter 74; however, the Government Code
    defines “includes” as a term “of enlargement and not of limitation or exclusive
    19
    enumeration, and use of [includes] does not create a presumption that components
    not expressed are excluded.” TEX. GOV’T CODE ANN. § 311.005(13) (West 2013);
    see Vicento, 
    164 S.W.3d at 731
     (applying Government Code’s definition of
    “includes” when analyzing section 74.402 of Texas Civil Practice and Remedies
    Code defining “practicing health care”). Likewise, it has been stated that “[t]he
    verb to include introduces examples, not an exhaustive list.” ANTONIN SCALIA &
    BRYAN GARNER, READING LAW 132 (2012). Thus, a statutory definition that
    specifies that it “includes but is not limited to” certain activities will be read to
    allow within it other, non-enumerated activities as well. Cf. Benavides v. Garcia,
    
    278 S.W.3d 794
    , 797 (Tex. App.—San Antonio 2009, pet. denied) (interpreting
    same provision—section 74.401—and holding that witness who was practicing
    medicine as locum tenens physician—defined as physician who substitutes for
    another temporarily—qualified as “practicing medicine” and as expert witness).
    Accordingly, we conclude that section 74.401’s use of phrase “includes, but is not
    limited to” requires that the activities that qualify as “practicing medicine” not be
    restricted to training at an accredited medical school and serving as a consultant to
    physicians as detailed in section 74.401(g).
    4.     Definitions of “practicing” and “medicine”
    Dr. Benge argues that, even if the phrase “practicing medicine” includes
    more than the two examples listed in the statute—i.e., training and consulting—it
    20
    must be limited to physicians who actively are examining or admitting patients into
    hospitals. Again we disagree.
    To ascertain legislative intent, we first look to the plain meaning and
    common usage of the words chosen by the Legislature. TEX. GOV’T CODE ANN.
    § 311.011 (West 2013); see St. Luke’s Episcopal Hosp. v. Agbor, 
    952 S.W.2d 503
    ,
    505 (Tex. 1997) (“The Legislature’s intent is determined from the plain and
    common meaning of the words used.”). The word “practice” means “to be
    professionally engaged in” a subject. MERRIAM-WEBSTER’S COLLEGIATE
    DICTIONARY 974 (11th ed. 2003). The word “medicine” is defined as “the science
    and art dealing with the maintenance of health and the prevention, alleviation, or
    cure of disease.” Id. at 771. The phrase “practice of medicine” has been given its
    own definition: “the learned profession that is mastered by graduate training in a
    medical school and that is devoted to preventing or alleviating or curing diseases
    and injuries.”4
    Accordingly, we conclude that the phrase “practicing medicine” in section
    74.401(a)(1) includes a variety of tasks performed by licensed physicians,
    professionally engaged in preventing, alleviating, and curing diseases and injuries.
    A physician may be devoted to preventing, alleviating, or curing diseases and
    4
    “Practice of medicine,” http://www.webster-dictionary.org (last visited Oct. 23,
    2014); “Practice of medicine,” http://www.thefreedictionary.com (same);
    “Practice of medicine,” http://www.definitions.net (same).
    21
    injuries through tasks other than “treating” or “admitting” patients. Cf. Schneider v.
    Fried, 
    320 F.3d 396
    , 407 (3d Cir. 2003) (holding that trial court erred by excluding
    cardiologist expert who had stopped performing angioplasties but continued to
    advise interventional cardiologists who performed angioplasties).
    Further, because the statute uses the phrase “includes, but is not limited to,”
    we conclude that the “practicing medicine” requirement for medical liability
    experts allows for geographical movement so long as the physician continues to
    professionally engage in and actively use his medical knowledge as the statute
    requires. Cf. Peterson v. Shields, 
    652 S.W.2d 929
    , 930–31 (Tex. 1983) (rejecting
    locality rule); TTHR, L.P. v. Guyden, 
    326 S.W.3d 316
    , 321 (Tex. App.—Houston
    [1st Dist.] 2010, no pet.) (stating that the term physician “does not impose any
    geographical limits”); accord N.H. Ins. Co. v. Allison, 
    414 S.W.3d 266
    , 274 (Tex.
    App.—Houston [1st Dist.] 2013, no pet.). Dr. Patsner received his training and
    board certification in the United States and practiced and taught medicine in
    Houston the majority of his career. This case does not concern the qualification of
    a physician who trained, practiced, and taught in another country and then came to
    Texas to testify.
    In conclusion, we construe “practicing medicine,” within the context of
    section 74.401, to include a physician who is licensed to practice in the United
    States, has actively practiced medicine by consulting with other physicians and
    22
    teaching medical residents in Texas, and then moved to another country where he
    continues to consult with that country’s physicians and teach its medical residents,
    all the while maintaining his affiliation with a Texas medical school, working on
    NIH grants, and teaching—with hands-on involvement—surgical procedures
    abroad through volunteer service. See TEX. CIV. PRAC. & REM. CODE ANN.
    §74.401; Larson, 197 S.W.3d at 304–05 (stating that “expert qualifications should
    not be too narrowly drawn”).
    C.    Trial court did not err in concluding that Dr. Patsner was practicing
    medicine
    Once we interpret the applicable statute as a matter of law, the issue of
    whether a particular witness qualifies as an expert under that statute is left to the
    trial court’s discretion. See Broders, 924 S.W.2d at 151; Daniels, 175 S.W.3d at
    893. We will not find that the trial court abused its discretion in finding Dr. Patsner
    was qualified unless it acted without reference to any guiding rules or principles.
    Daniels, 175 S.W.3d at 893–94; Larson, 197 S.W.3d at 304–05.
    The following evidence supports the trial court’s ruling:
    • Dr. Patsner’s substantive (versus temporal) qualifications are
    unchallenged. Dr. Patsner is a board-certified gynecologist and has
    maintained his certification at all times relevant to this suit. He has years
    of experience practicing and teaching in the area of gynecology.
    • Dr. Patsner has expertise in the very issue presented in this case; he
    estimates that he has directly performed or first-assisted 450 laparoscopic
    hysterectomies and more than 6,000 abdominal or vaginal hysterectomies
    during his career.
    23
    • Dr. Patsner continued to participate “hands-on” in gynecological cancer
    surgeries up to and after the date of his testimony through international
    aid work.
    • Dr. Patsner’s work in Korea, where he had begun working by the time
    the case went to trial, was substantially similar to the work he performed
    at Baylor and Ben Taub.
    • The time period between Dr. Patsner’s last teaching assignment at Baylor
    and his teaching assignment in Korea was relatively short.
    • Dr. Patsner’s expertise in gynecology was recognized by Ben Taub,
    where he was appointed the Assistant Director of Gynecological
    Oncology and ran four clinics weekly.
    • Dr. Patsner performed similar teaching tasks in Korea as he had at Baylor
    College of Medicine, a research and teaching hospital in Houston. While
    the record is silent on whether the Yonsei medical school—as opposed to
    the affiliated teaching hospital—is accredited, his professional work was
    functionally equivalent to the teaching he had been doing at Baylor
    several months before his trial testimony.
    • Dr. Patsner maintained, through the date of trial, an affiliation with
    Baylor in Texas: “[W]e’re still doing research. I still have my name on
    NIH grants at Baylor in their genetics and ovarian cancer laboratory.”
    We conclude that the trial court did not abuse its discretion in admitting Dr.
    Patsner’s testimony. See Broders, 924 S.W.2d at 151. We therefore overrule Dr.
    Benge’s first issue.
    Casteel Challenge to Broad-form Negligence Question
    In his second issue, Dr. Benge argues that the “trial court erred when it
    mixed valid and invalid legal theories in a broad-form jury question over
    Defendants’ objection.” According to Dr. Benge, the broad-form question mixed a
    valid theory (negligence) with an invalid theory (lack of consent). Dr. Benge
    24
    contends that the mixing of these two theories violated Crown Life Insurance
    Company v. Casteel, 
    22 S.W.3d 378
     (Tex. 2000).
    The standard of review for claims of charge error is abuse of discretion. Tex.
    Dep’t of Human Servs. v. E. B., 
    802 S.W.2d 647
    , 649 (Tex. 1990); Powell Elec.
    Sys., Inc. v. Hewlett Packard Co., 
    356 S.W.3d 113
    , 122 (Tex. App.—Houston [1st
    Dist.] 2011, no pet.). Therefore, we review a trial court’s decision to deny a
    requested instruction under that standard of review. Thota v. Young, 
    366 S.W.3d 678
    , 687 (Tex. 2012). An instruction that might aid the jury in answering the jury
    questions is proper. 
    Id.
     When a trial court refuses to submit a requested instruction,
    “the question on appeal is whether the request was reasonably necessary to enable
    the jury to render a proper verdict.” Shupe v. Lingafelter, 
    192 S.W.3d 577
    , 579
    (Tex. 2006). If the jury charge was erroneous, we must then consider whether the
    error requires reversal. Powell, 
    356 S.W.3d at 122
    .
    A.    What constitutes a Casteel problem
    Casteel and its progeny teach that a jury charge is erroneous when a jury
    answers a single broad-form liability question affirmatively, the single liability
    question incorporates multiple legal theories, and at least one of those legal
    theories does not support liability as a matter of law and therefore is invalid.5
    Casteel, 22 S.W.3d at 387–89. The “erroneous commingling of valid and invalid
    5
    Mixing valid and invalid damages elements also creates a Casteel problem. Harris
    Cnty. v. Smith, 
    96 S.W.3d 230
    , 234 (Tex. 2002).
    25
    theories of liability in a broad-form liability question” makes it impossible for an
    appellate court to “determine whether the jury based its verdict on an improperly
    submitted theory.” Burbage v. Burbage, No. 12-0563, 
    2014 WL 4252274
    , at *4
    (Tex. Aug. 29, 2014).
    A theory may be invalid for a variety of reasons, including lack of standing
    (Casteel, 22 S.W.3d at 387–89), lack of supporting evidence (Romero v. KPH
    Consolidation, Inc. d/b/a Columbia Kingwood Medical Center, 
    166 S.W.3d 212
    , 225,
    227–28 (Tex. 2005)), or a failure to plead it (Texas Commission on Human Rights
    v. Morrison, 
    381 S.W.3d 533
    , 537 (Tex. 2012) (plaintiff did not claim denial of
    promotion, only wrongful termination and retaliation, and could not do so because
    she did not pursue that claim before EEOC)). “A trial court errs by submitting to
    the jury theories of liability that are not legally viable—e.g., liability theories that
    [1] have not been pled, [2] are not supported by the legally sufficient evidence, or
    [3] are not supported by operative law.” Powell, 
    356 S.W.3d at 123
    . Thus, the
    inquiry is not limited to whether an invalid theory was pleaded. If one of the
    plaintiff’s legal theories does not support liability as a matter of law and the
    plaintiff presented evidence to the jury on that theory that may have led the jury to
    answer affirmatively the broad-form liability question incorporating the invalid
    theory, there is a Casteel-type charge error. See Columbia Rio Grande Healthcare,
    L.P. v. Hawley, 
    284 S.W.3d 851
    , 863–65 (Tex. 2009) (broad-form negligence
    26
    question included instruction that hospital acts through its employees, agents,
    nurses, and servants but did not inform jury that hospital is not legally liable for
    acts of independent contractor-physician and, as result, appellate court could not
    tell if jury impermissibly found hospital liable for acts of doctor where evidence
    raised that possibility).
    In Casteel, the theory was invalid due to an issue of standing. 22 S.W.3d at
    387–89. The plaintiff asserted that the defendant engaged in a number of unfair or
    deceptive practices that violated the Insurance Code and DTPA. Id. at 381–82. In
    response to a single broad-form question, the jury found the defendant liable. Id. at
    387. Because the liability theories were combined in a single question, it was
    unclear if the jury had assigned liability based on a finding of an Insurance Code
    violation or DTPA violation. See id. The plaintiff could not recover on four DTPA
    claims because he was not a consumer. Id. at 387–88. The Texas Supreme Court
    held that when a jury question mixes valid and invalid liability theories and it
    cannot be determined on which theory the jury based its liability finding, appellate
    courts will presume harm, reverse, and remand the cause for a new trial using a
    legally correct jury charge. See id. at 387–90. To avoid this risk, “when the trial
    court is unsure whether it should submit a particular theory of liability, separating
    liability theories best serves the policy of judicial economy underlying Rule
    277 . . . .” Id. at 390; see also Powell, 
    356 S.W.3d at 123
     (stating that “judicial
    27
    economy may favor separate submission of liability theories to prevent the need to
    re-try the cause of action if the trial court reaches an incorrect decision with regard
    to which theories of liability should be submitted to the jury.”).
    In this case, the jury was asked a single liability question, phrased as
    “negligence.” We first consider whether the question effectively presented the
    theory of informed consent in addition to surgical and post-surgical negligence,
    taking into consideration Williams’s evidence and arguments as well as the
    overlapping nature of the negligence and informed consent theories. We conclude
    that, as a result of the combination of these circumstances, the single question here
    effectively included two distinct liability inquiries.
    B.    Williams’s theories of liability
    Williams argues that the charge does not violate Casteel because Dr.
    Benge’s disclosures, or lack thereof, “are simply facts, not theories of liability.”
    While evidence of Dr. Giacobbe’s experience was a relevant fact, and not a
    pleaded theory of liability, the evidence regarding the disclosures went far beyond
    simply the facts. Evidence regarding the disclosure issue was a major theme of
    Williams’s case and was explicitly incorporated into liability questions asked of
    her expert, Dr. Patsner.
    The jury was asked only one liability question: “Did the negligence, if any,
    of any of those named below proximately cause Lauren Williams’ injuries in
    28
    question?” Blanks were provided to allow the jury to assign liability to Dr. Benge,
    Dr. Thornton, and Williams. Negligence, with respect to Dr. Benge, was defined
    for the jury to mean “failure to use ordinary care that is, failing to do that which an
    obstetrician/gynecologist of ordinary prudence would have done under the same or
    similar circumstances or doing that which an obstetrician/gynecologist of ordinary
    prudence would not have done under the same or similar circumstances.”
    Throughout trial, Williams presented evidence on and argument about the
    standard of care, meaning what an obstetrician/gynecologist of ordinary prudence
    would have done during or after her hysterectomy. Under one of Williams’s
    theories, either Dr. Benge or the resident perforated Williams’s bowel, causing
    feces to enter her abdominal cavity, which ultimately resulted in sepsis, multiple
    operations, a lengthy coma, and an irreversible colostomy. Williams contended that
    an ordinarily prudent gynecological surgeon would not have made such an error
    and, therefore, Dr. Benge was negligent.
    She further contended that an ordinarily prudent gynecological surgeon
    would not have allowed such an inexperienced resident to perform a large portion
    of the surgery, as Dr. Benge did. Dr. Giacobbe’s level of experience and Dr.
    Benge’s knowledge of that information were both relevant to that claim. Relatedly,
    and to the extent it was Dr. Giacobbe who erred, the parties do not dispute that Dr.
    29
    Benge, as Williams’s surgeon with a supervising role over the resident, was legally
    liable for both his own surgical errors and those of the resident he was supervising.
    The surgical error claim, in its many iterations—i.e., that Dr. Benge was
    liable if he (1) negligently perforated Williams’s bowel, (2) negligently allowed
    Dr. Giacobbe to actively participate in the surgery resulting in Dr. Giacobbe
    perforating the bowel, or (3) reasonably allowed Dr. Giacobbe to operate but then
    was legally liable when she perforated Williams’s bowel—was not the only theory
    Williams presented to the jury.
    Under her unpleaded informed consent theory, Dr. Benge knew an
    inexperienced resident was going to perform a substantial portion of the surgery
    under his supervision and he negligently failed to provide that information to
    Williams before the operation. Williams testified that she had no idea that a
    resident was going to do a substantial portion of her LAVH or that her surgery
    would be that resident’s first experience performing such a procedure. Further,
    Williams testified that, had she known that information, she would not have agreed
    to the operation and, as such, would not have suffered any of her injuries. Williams
    testified that she was never orally informed that Dr. Benge would be assisted by a
    resident (as opposed to the written consent forms informing her that he might be
    assisted by a resident) or that the resident might or would perform a large portion
    of the surgery. Williams’s expert, Dr. Patsner, testified that Dr. Benge’s failure to
    30
    disclose Dr. Giacobbe’s involvement to Williams fell below the standard of care.
    Under this theory, the question of what a gynecological surgeon of ordinary
    prudence would do was not addressed to either doctor’s surgical techniques but,
    instead, whether the hired surgeon (Dr. Benge) should have disclosed to the patient
    that another surgeon with limited experience would perform a substantial portion
    of the operation. To complete the necessary elements for a finding of negligence
    under this theory, Williams presented evidence on causation and damages with
    Williams’s testimony that she would not have consented to Dr. Giacobbe’s
    substantial involvement had she known and with Dr. Patsner’s testimony that, in
    his opinion, Williams’s substantial injuries were caused by Dr. Giacobbe
    perforating her bowel. This second theory asserted that Dr. Benge was negligent
    and caused her injures simply by not telling Williams about Dr. Giacobbe.
    Williams insists that the failure-to-disclose theme was a “small piece of
    evidence” supporting a finding of medical negligence. She correctly observes that
    jurors do not have to agree on the basis for the negligence and that even if jurors
    believed Dr. Benge “was wrong not to tell [Williams] about the resident’s
    involvement,” they still could have found that Benge used “poor surgical
    technique.” She contends that the poor surgical technique claim was “the focus of
    the trial.” Further, Williams asserts that evidence regarding these non-disclosures
    was offered to demonstrate that Benge was “deceitful,” committed a “betrayal,”
    31
    and “broke a promise.” Thus, the evidence, she urges, was presented “for the jury’s
    credibility determination,” not as a basis for finding liability. Dr. Benge does not
    dispute that evidence regarding Dr. Giacobbe’s experience was relevant to the
    claim that Dr. Benge was negligent during the surgery. A reasonable jury could
    have determined that the amount of supervision required over an assistant and the
    tasks delegated to the assistant vary according to the resident’s experience.
    However, he disagrees that the evidence was presented as just a “small piece” of
    the trial.
    A review of the record reveals that Williams went beyond offering
    admissible facts regarding Dr. Giacobbe’s background and Dr. Benge’s knowledge
    of her limitations. Most significantly, Williams’s medical liability expert testified
    that the failure to disclose was a violation of the standard of care:
    Q:    Would you say that [Dr. Benge] violated the standard of care if
    he did not explain that the third-year resident—doing this, her
    first-time procedure—was going to be performing a part of the
    surgery?
    A:    Well, yes. . . . You can’t have ghost surgeons.
    Q:    Period? End of story?
    A:    Period.
    Dr. Patsner further testified:
    [Y]ou have to get consent from your patients that a resident is going
    to be do—is going to be with you in the operating room. . . . And do
    patients occasionally say no? Yes, they do. I mean, sometimes people
    32
    don’t want to be operated on by people who haven’t finished their
    training. Sometimes they want people with more experience. So the
    circumstances can vary. The—the standard of care is to get
    permission from the patient for everybody who’s going to be
    operating on them.
    Again Dr. Patsner testified:
    Q:     Do you believe that Dr. Benge fell below the standard of care
    when he allowed someone without the express consent to
    operate on Lauren Williams?
    A:     Yes.
    Finally, Dr. Patsner testified:
    Q:     The area of betrayal, the failure—the failure of Dr. Benge to
    explain who was doing the surgery on Ms. Williams—was that
    below the standard of care?
    A:     Yes. It was outside the standard.
    Q:     In your opinion, was that a breach of the standard of care? Was
    that negligent?
    A:     Yes. 6
    6
    That testimony was disputed. Dr. Toy, a board certified physician who served as
    the residency program director where Dr. Giacobbe was a resident, testified that
    express permission by the patient for the resident to “perform a surgery” is not
    required because the resident is in an assistant role, always under the supervision
    of the attending physician and that the “standard of care does not require
    disclosure that the resident is putting hands on the patient.” Dr. Zepeda, a defense
    expert witness, also discussed the standard of care. He testified that the standard
    consent form used by Dr. Benge granted permission for the use of a resident when
    completing the procedure. Finally, Dr. Benge testified that his practice with regard
    to disclosing resident participation in surgical procedures was consistent with
    standard practices and was reasonable. He further testified that his disclosure
    complied with American Medical Association guidelines for the use of residents
    during surgery when “the usual form of consent” is used and the named surgeon
    has “participatory supervision” over the resident’s work. The AMA guidelines
    33
    Williams presented a repeated trial theme seeking liability based on the
    failure-to-disclose theory, which culminated in the final moments of jury argument
    with her request that the jury “send . . . a message” to the medical community that
    it can no longer rely on a “vaguely worded” disclosure forms to permit active
    participation by residents in the operating room. Williams asked for a finding of
    liability for failing to disclose more information about the participation of the
    resident, whom she described as a “secret surgeon.”
    This theme was established from the beginning of trial. Williams opened the
    trial by informing the jury: “We’re suing Kelsey-Seybold for six reasons. First
    reason: betrayal by the Kelsey-Seybold doctor to bring in a surgeon who had no
    permission, who had no consent to put her hands on Lauren.” Williams then told
    the jury that there were three “steps to betrayal”: trust, vulnerability, and betrayal
    itself, which she described as letting a “secret surgeon, a first-time resident, do a
    significant part of this procedure.”
    During closing, Williams explained that she hired “his hands, his
    experience; but under anesthesia, she got another set of hands working on her . . . a
    provide that, when the “usual form of consent to operation” is used, it is
    permissible for “the operating surgeon to delegate the performance of certain
    aspects of the operation to the assistant provided this is done under the surgeon’s
    participatory supervision, ie, the surgeon must scrub.” On the other hand, “[i]f a
    resident or other physician is to perform the operation under non-participatory
    supervision, it is necessary to make a full disclosure of this fact to the patient.”
    34
    set of hands she did not know, who had never done the job before, had no
    experience. You can’t do this in our community.” She then sought a jury verdict
    based on her “betrayal” theory:
    The best thing they can say is “We’re good people. We didn’t mean it.
    We’re sorry. . . . The fact that we didn’t tell them who was doing the
    surgery is—it should be of no concern to you because that’s the way
    we want to do business.” . . . [E]ach one of you—take it upon
    yourselves to make them change the way they do business.
    . . . .
    If you want this fiction to continue or to grow throughout the country,
    find for them. You are the conscience of the community. If that’s what
    you want the standard to be, I’m telling you right now your job will be
    very quick. Go back and find for them. That will give them the
    approval. It’ll give them the consent, and it will be publicized
    throughout the industry, “This is how you do it. Don’t tell the patient.
    It makes things a whole lot easier. We can get a whole lot more
    training. You just don’t tell the patient.”
    Williams told the jury that it could impact the practice within the medical
    community concerning “secret” surgeons:
    If you approve that standard today, that will become the standard. You
    disapprove that standard today, you send them a message, the standard
    changes. Our community is a safer place to live. That’s why I say you
    are the caretakers of our community. You set the standard. You make
    it safer for everyone in this courtroom, all of their family, all of their
    friends, or you can sit silently by and let it continue. Your choice.
    Given a one-minute warning at the conclusion of her closing argument,
    Williams asked the jury “to enforce the safety rules” through its verdict:
    If you choose to do so, if you think these rules are important and need
    to be enforced, say so by your verdict. You are the conscience of the
    community. If you don’t think they’re important, put zero, put zero,
    because your verdict will be heard. It will be heard by this
    35
    organization, this group. . . . They are going to go back doing the
    same thing they’ve been doing, not telling people about who’s doing
    the operation.
    The disclosure theory was a primary theme of the case.
    If the jury, as Williams suggested, agreed that using a “secret surgeon” was
    not what they “want[ed] the standard to be,” and further decided that the
    ordinarily-prudent-physician standard required disclosure of the resident’s role,
    then this theory could have led the jury to conclude that Dr. Benge breached his
    general duty of ordinary care to Williams—completely independent of whether he
    or Dr. Giacobbe negligently perforated Williams’s bowel. And it could have found
    causation because Williams testified that she would not have undergone the
    surgery if Dr. Giacobbe’s role had been disclosed. This trial theme and the
    evidence presented to the jury created the possibility of a liability finding based on
    either of the two negligence theories: negligence during and after the surgery and
    negligence before the surgery in failing to disclose Dr. Giacobbe’s participation or
    level of experience.
    C.    The broad form negligence question effectively included an informed
    consent issue and therefore violated Casteel
    Williams responds that the broad-form jury question did not include this
    second theory; it asked only a general negligence question, thus precluding a
    Casteel error. We therefore next examine whether a reasonable jury could have
    concluded that the general negligence question subsumed the informed consent
    36
    issue. Based on the evidence and arguments presented, we conclude that the jury
    could have, and therefore the broad-form charge violated Casteel.
    An informed consent claim is a subspecies of a negligence claim. In such a
    claim, “the only theory on which recovery may be obtained is that of negligence in
    failing to disclose the risks or hazards that could have influenced a reasonable
    person in making a decision to give or withhold consent.” TEX. CIV. PRAC. & REM.
    CODE ANN. § 74.101 (West 2011) (emphasis added); see also Schaub v. Sanchez,
    
    229 S.W.3d 322
    , 323 (Tex. 2007) (stating that a plaintiff “can prevail on her
    informed consent claim only if she shows that the doctors negligently failed to
    disclose the procedure’s risks or hazards. . . . [U]nder [the statute], lack of
    informed consent is a particular subspecies of negligence based on a failure to
    disclose the risks or hazards of a procedure.”). And whether a physician was
    negligent in his treatment of a patient is a distinct legal question from whether the
    physician was negligent in failing to disclose to the patient the risks inherent in the
    treatment. Felton v. Lovett, 
    388 S.W.3d 656
    , 663 (Tex. 2012). A jury, therefore,
    should be asked separate questions for the two theories. See Hawley, 284 S.W.3d at
    863–65.
    Medical non-disclosure negligence claims are not the only negligence claims
    governed by specific principles of duty. For example, premises liability claims and
    negligent undertaking claims are negligence claims that have defined duty
    37
    standards. For these claims, a broad-form negligence question is erroneous and
    cannot support a judgment. Torrington Co. v. Stutzman, 
    46 S.W.3d 829
    , 837–38
    (Tex. 2000) (concluding that negligent undertaking claim requires three additional
    predicate instructions to determine if there is a duty to exercise ordinary care);
    Clayton W. Williams, Jr., Inc. v. Olivo, 
    952 S.W.2d 523
    , 529 (Tex. 1997) (holding
    that broad-form negligence question that omitted elements of premises liability
    claim was insufficient); see also Torrington, 46 S.W.3d at 838 (“In premises
    liability cases, like undertaking cases, a possessor of land may be held liable only
    if certain conditions are met.”); Custom Transit, L.P. v. Flatrolled Steel, Inc., 
    375 S.W.3d 337
    , 362 (Tex. App.—Houston [14th Dist.] 2012, pet. denied) (noting that
    both premises liability and negligent undertaking claims involve different duties
    than basic negligence claims and holding that broad-form negligence submission
    was error for negligent undertaking claim); Price Drilling Co. v. Zertuche, 
    147 S.W.3d 483
    , 488 (Tex. App.—San Antonio 2004, no pet.) (when plaintiff’s claim
    could “only be characterized as a premises liability claim,” submission of ordinary
    negligence questions and instructions resulted in waiver of premises defect claim).
    Williams contends that Casteel does not govern alternative factual
    assertions, only different liability theories. We agree, but do not find this
    distinction applicable in this case. In Columbia Medical Center of Las Colinas v.
    Bush ex rel. Bush, 
    122 S.W.3d 835
     (Tex. App.—Fort Worth 2003, pet. denied), a
    38
    defendant hospital requested limiting instructions that the jury could not consider
    specific acts in its evaluation of negligence. 
    Id.
     at 857–58. The trial court refused,
    and the hospital appealed. 
    Id.
     The appellate court concluded that the case involved
    alternative factual allegations in support of a single legally grounded theory, not
    multiple liability theories, one of which was defective. 
    Id.
     at 858–59.
    The difference is critical. For example, in Hawley, a broad-form negligence
    question included an instruction that a hospital acts through its employees, agents,
    nurses and servants. 284 S.W.3d at 863. Yet the charge said nothing about the
    hospital’s undisputed lack of liability for the conduct of a physician who acted as
    an independent contractor. Id. at 862–63. Although the charge’s statement that a
    hospital acts through these four categories of individuals was not improper, the
    Court held that it was error to refuse an additional requested instruction clarifying
    this issue because the jury “could have considered” the physician as an agent of the
    hospital. Id. at 863. “The hospital’s request was designed to prevent that from
    happening” by providing a proper limiting definition and instruction that would
    have assisted the jury. Id. at 863–64. Moreover, the plaintiffs did “not complain
    that the instruction would have ‘tilted’ the jury against them in some manner;” on
    the contrary, they asserted that the failure to give the instruction was not error
    because the issue was undisputed. Id. at 864.
    39
    Similarly, Dr. Benge submitted an instruction that would have clarified that
    Williams could not recover on an informed consent negligence theory: “You are
    instructed that in deciding whether any defendant was negligent, you cannot
    consider what the defendant told, or did not tell, the plaintiff about the resident
    physician being involved with the surgery.” Dr. Benge’s proposed instruction,
    which the trial court refused, would have properly limited the jury to the issue that
    Williams states was her only claim: negligent medical treatment during and after
    the surgery. And like the plaintiff in Hawley, Williams did not make any complaint
    about the substance of the proposed instruction in the trial court or on appeal. The
    instruction here did not tilt the jury insofar as the physicians’ surgical technique
    and level of experience was at issue. Nor did it prevent the jury from considering
    Dr. Giacobbe’s level of experience and Dr. Benge’s knowledge of that information
    when he permitted Dr. Giacobbe to perform a large portion of the surgery. The
    proposed instruction would not have prevented the jury from considering that
    information to determine whether Dr. Benge or Dr. Giacobbe were negligent in
    their medical treatment of Williams; it only would have limited the jury from
    considering what Dr. Benge told Williams regarding that information—beyond the
    signed consent forms 7—in deciding if he acted negligently. 8
    7
    The consent form states, “I [_____] voluntarily request Dr. [_____] as my
    physician and such associates, technical assistants and other health care providers
    as they may deem necessary, to treat my condition which has been explained to
    40
    Likewise, this case is similar to Hawley because although there was only a
    single jury question, the jury was presented with multiple theories in that one
    question and that error could have been easily resolved with a simple instruction.
    The instruction in Hawley asking whether the employees, agents, nurses or
    servants were negligent “effectively submitted four negligence questions.” Hawley,
    284 S.W.3d at 864. Here the single question also “effectively submitted” two
    different negligence questions.
    The Texas Supreme Court in a second case also concluded that a single
    broad-form question violated Casteel even though the accompanying definitions
    and instructions did not explicitly contain multiple theories because the broad form
    subsumed within it an improper theory and evidence had been submitted in support
    of that theory. Morrison, 381 S.W.3d at 537. In that wrongful termination lawsuit,
    the jury was asked whether the defendant took “adverse personnel actions” against
    the plaintiff because of her opposition to an unlawful discriminatory practice. Id. at
    536. The plaintiff presented evidence relevant to her wrongful termination claim
    me (us) as [_____].” It continues, “I (we) understand that the physician may
    require other physicians including residents to perform important tasks based on
    their skill set and, in the case of residents, under the supervision of the responsible
    physician. (Residents are doctors who have finished medical school but are getting
    more training.).”
    8
    An alternative instruction would have been that the jury could only consider
    whether the doctors’ acts or omissions during or after the surgery constituted
    negligence. That would have prevented a finding of negligence based solely on the
    failure to disclose to Williams more information about the participating resident.
    41
    that she was denied a promotion, but she did not raise such a claim (and could not
    do so because it was not part of her underlying EEOC complaint). Id. at 537. The
    Court concluded that the charge violated Casteel. “Because the jury question
    allowed liability for ‘adverse personnel actions,’ the jury could have improperly
    found liability based upon the denied promotion.” Id.
    Williams repeatedly stressed to the jury that Dr. Benge did not inform her of
    Dr. Giacobbe’s role or experience. Importantly, she also presented expert
    testimony that the failure to do so violated the standard of care. She disclaims that
    theory on appeal, stating “this is a surgical neglect case” and “the only question
    before the jury that’s at issue in this appeal was on Benge’s surgical negligence,”
    and disclaiming that she “sought [any] recovery” on an informed consent claim.
    The jury, however, was unaware of this limitation, and the rejected instruction
    would have made this point clear for it.
    The introduction of evidence admissible for multiple purposes does not in
    itself create a Casteel problem. But the broad-form negligence question here
    necessarily included a non-disclosure legal theory because the evidence explicitly
    included standard-of-care questions on informed consent. Much like a limiting
    instruction is appropriate when evidence is admissible for one purpose but
    inadmissible for another purpose, the requested instruction would have focused the
    jury properly on the issues of negligence during and after the surgery and away
    42
    from the theory of non-disclosure. Without the requested instruction, a jury in this
    situation “could have improperly found liability based upon” the unpleaded
    informed consent issues. Morrison, 381 S.W.3d at 537; see also Hawley, 284
    S.W.3d at 863 (charge violated Casteel because jury “could have considered”
    physician as agent of hospital).
    Finally, Williams asserts that a holding that the trial court abused its
    discretion in refusing to include the requested instruction is contrary to the
    preference for broad-form submission “whenever feasible.” See TEX. R. CIV. P.
    277; Thota, 366 S.W.3d at 688–89. But our system of justice likewise requires the
    jury to be properly instructed in the law and that broad form is appropriate only
    when it is feasible. Casteel, 22 S.W.3d at 388. We conclude that the broad-form
    medical negligence question here effectively subsumed an informed consent issue.
    We next address whether Williams’s second theory—a failure-to-disclose
    theory—was an invalid theory.
    D.    Whether Williams’s “secret surgeon” theory of liability was valid as a
    stand-alone negligence claim
    1.     Duty is a question of law
    Because an informed consent claim is a subspecies of negligence, it includes
    the traditional elements of that claim: breach, causation, and damages. But like
    negligence claims, the threshold issue is whether there is a duty because, if there is
    no duty, there is no liability. See Greater Hous. Transp. Co. v. Phillips, 801
    
    43 S.W.2d 523
    , 525 (Tex. 1990); El Chico Corp. v. Poole, 
    732 S.W.2d 306
    , 311 (Tex.
    1987) (superseded by statute on other grounds); Graff v. Beard, 
    858 S.W.2d 918
    ,
    919 (Tex. 1993).
    A jury cannot decide whether an individual has a duty; duty is a question of
    law left to the court’s determination. See Phillips, 801 S.W.2d at 525; see also
    Torrington, 46 S.W.3d at 837–38. A jury finding that a defendant failed to use
    reasonable care cannot result in a negligence finding unless the plaintiff first
    establishes that the defendant had a legal duty to act. See El Chico Corp., 732
    S.W.2d at 311. We consider whether the law imposes a legal duty on a physician to
    disclose information about the level of a resident’s participation beyond the
    standard disclosure form language used in this case that a “resident” may “assist”
    the surgeon, including performing “important tasks” during the surgery.
    2.     No duty under TMLA
    “Health care must be based on a patient’s informed consent.” Felton, 388
    S.W.3d at 658. The Texas Medical Liability Act, which governs causes of action
    based on health care liability claims, sets forth the elements of a claim for failure to
    obtain informed consent. See TEX. CIV. PRAC. & REM. CODE ANN. § 74.101. Under
    section 74.101, informed-consent claims are “based on the failure of the physician
    or health care provider to disclose or adequately disclose the risks and hazards
    44
    involved in the medical care or surgical procedure rendered by the physician or
    health care provider.” Id.
    Section 74.102 implements the long-established rule that medical treatment
    requires a patient’s informed consent, see Binur v. Jacobo, 
    135 S.W.3d 646
    , 654–
    55 (Tex. 2004), by creating a Texas Medical Disclosure Panel “to determine which
    risks and hazards related to medical care and surgical procedures must be disclosed
    by health care providers or physicians to their patients or persons authorized to
    consent for their patients and to establish the general form and substance of such
    disclosure.” TEX. CIV. PRAC. & REM. CODE ANN. § 74.102 (West 2011). The Panel
    evaluates all medical and surgical procedures, determines if disclosure of risks is
    required, and if so, determines how much disclosure is required. Bryan v.
    Watumull, 
    230 S.W.3d 503
    , 508 (Tex. App.—Dallas 2007, pet. denied). The Panel
    creates two lists reflecting its conclusions, Lists A and B. “If the procedure
    requires some disclosure of the risks involved in the treatment, it is placed on List
    A. However, if the Panel determines that no disclosure is required, the procedure is
    placed on List B.” 
    Id.
     at 508–09 (citations omitted).
    List A identifies the disclosures required for the medical procedures
    involved in this case: vaginal hysterectomy, fallopian tube and ovarian removal
    surgery, and abdominal laparoscopic procedures. See 25 TEX. ADMIN. CODE
    §§ 601.2(g)(2), g(3), & (s) (West 2014). It does not require any disclosure of the
    45
    experience or role of a resident surgeon. When a procedure is included on List A,
    conformity with its requirements creates a rebuttable presumption that the
    physician was not negligent. Bryan, 
    230 S.W.3d at 509
    ; TEX. CIV. PRAC. & REM.
    CODE ANN. §§ 74.104, 74.106(a)(1).
    Because the presumption is rebuttable, we will examine whether there is any
    other source of a duty for Dr. Benge to disclose Dr. Giacobbe’s level of
    participation or experience. See Felton, 388 S.W.3d at 660 (stating that if section
    74.401 does not apply, the common law does); Cf. TEX. CIV. PRAC. & REM. CODE
    ANN. § 74.106(b) (when procedure is not covered by List A or B, issue is whether
    there is duty “otherwise imposed by law.”).
    3.    No duty under the common law
    The common law imposes on “‘[p]hysicians and surgeons [the] duty to make
    a reasonable disclosure to a patient.’” Felton, 388 S.W.3d at 660 (quoting Wilson
    v. Scott, 
    412 S.W.2d 299
    , 301 (Tex. 1967)). A reasonable disclosure will include
    “the risks that would influence a reasonable patient in deciding whether to undergo
    treatment but not those that would be unduly disturbing to an unreasonable
    patient.” Id. at 661. The risks that must be disclosed are those “inherent” in
    treatment, meaning a risk “that ‘exists in and is inseparable from the procedure
    itself.’” Id. (citation omitted). “Inherent risks of treatment are those which are
    directly related to the treatment and occur without negligence.” Id. at 662. An
    46
    informed consent claim concerns “inherent risks” of the procedure—meaning
    negative results that can occur as a consequence of a properly performed
    procedure. It is the possibility of a negative consequence from a properly
    performed operation that is the operation’s inherent risk. Tajchman v. Giller, 
    938 S.W.2d 95
    , 98–99 (Tex. App.—Dallas 1996, writ denied).
    By contrast, a physician has no duty to disclose the risks that the surgery
    “may be based on an erroneous diagnosis or prognosis, or that it is negligently
    performed.” Felton, 388 S.W.3d at 662. “Malpractice . . . is an extraneous risk, one
    that inheres in the practice of health care, not in the care itself.” Id. “[O]nly
    inherent risks of a procedure—risks that arise from the procedure itself and not
    from any defect in the procedure or negligent human intervention—need be
    disclosed.” Tajchman, 938 S.W.2d at 99. The common law does not, therefore,
    recognize a duty to disclose such non-inherent risks and failure to disclose them
    cannot support a liability finding.
    Williams’s resident-disclosure theory does not concern a risk or hazard
    inherent to her hysterectomy surgery; this theory concerns the possibility that an
    inexperienced resident assisting in the surgery might negligently perform the
    operation and that Dr. Benge might negligently supervise her performance by not
    catching her error or by allowing her to do more of the surgery or too complex an
    aspect of the surgery given her limited experience. These are extraneous risks.
    47
    No Texas authority has recognized a duty to disclose the level of
    participation by the resident or that resident’s experience level. See Haynes v.
    Beceiro, 
    219 S.W.3d 24
    , 27 (Tex. App.—San Antonio 2006, pet. denied) (medical
    battery case; signature on standard consent and disclosure form permitted active
    participation in surgery by another doctor because patient consented to her chosen
    doctor and other “such associates” he deemed necessary to perform surgery); cf.
    Avila v. Flangas, No. 04-95-00106-CV, 
    1996 WL 63036
    , at *2 (Tex. App.—San
    Antonio Feb. 14, 1996, no writ) (mem. op., not designated for publication)
    (holding that claim that defendant physicians failed to disclose their inexperience
    was not inherent risk and therefore did not need to be disclosed; claim concerned
    negligent human intervention).
    While Williams did not sue under a medical battery theory, that cause of
    action raises issues similar to those underlying Williams’s informed consent
    theory. Medical battery is defined as performing a medical act or treatment on a
    patient without consent. See Haynes, 
    219 S.W.3d at 26
    . In Haynes, the plaintiff
    could not prevail on a medical battery claim against an assisting surgeon who
    participated in her surgery, even though she explicitly informed the surgeon’s staff,
    before her procedure, that “[s]he does not want to see anyone else—or have
    anyone else do surgery” besides the surgeon she selected. 
    Id. at 25
    . The Disclosure
    and Consent Form she signed stated that she was “voluntarily request[ing]” her
    48
    chosen surgeon “and such associates, technical assistants and other health care
    providers as they may deem necessary to treat my condition . . . .” 
    Id.
     The court
    held that consent, therefore, was given for the second surgeon to participate in her
    procedure. Id.; cf. Lane v. Anderson, 
    802 N.E.2d 1278
    , 1282–84 (Ct. App. Ill.
    2004) (holding, in medical battery case addressing level of participation by
    resident, that plaintiff does not have medical battery claim, as matter of law,
    against resident who “performed a majority of the surgery” because, by signing
    consent form, plaintiff consented to selected surgeon and his assisting resident,
    “regardless of the degree to which [the resident] participated”).
    4.     Conclusion on duty
    The Legislature has created a comprehensive statutory scheme concerning
    disclosure and informed consent law, and it is the Legislature’s prerogative to
    expand the level of disclosure required, should it see fit. See TEX. CIV. PRAC. &
    REM. CODE ANN. §§ 74.101–.107. Mindful of the statutory framework and
    following the analysis in Haynes, we conclude that Texas law does not impose a
    legal duty to disclose to a patient specific information about a consented-to
    assisting surgeon’s anticipated level of participation or experience. We further
    conclude that an assertion of medical negligence that characterizes the failure to
    disclose this information as a breach of duty presents an invalid legal theory.
    49
    We address next whether Dr. Benge preserved error on his Casteel
    challenge.
    E.       Whether Dr. Benge preserved Casteel error
    Any complaint to a jury charge, including “complaints of error in broad-
    form submission,” is waived unless a party “make[s] the trial court aware of the
    complaint, timely and plainly, and obtain[s] a ruling.” In re B.L.D., 
    113 S.W.3d 340
    , 349 (Tex. 2003). Objections must both “clearly designate the error” and
    “explain the grounds for complaint.” Burbage, 
    2014 WL 4252274
    , at *6. An
    objection must “explain the nature of the error” so the trial court may correct it. Id.
    at *7.
    Williams contends that Dr. Benge waived any error in the jury charge by
    failing to object during trial to questions asked of him on cross-examination about
    his non-disclosure of Dr. Giacobbe’s level of experience and surgical
    participation.9 However, the issue Dr. Benge raises on appeal is a legal one related
    to jury-charge error, not an evidentiary issue. Mid-trial evidentiary objections were
    not necessary to preserve this complaint. See Felton, 388 S.W.3d at 660 & n.9
    (noting that purely legal issues, which do not affect jury’s role as fact-finder, will
    preserve error even if raised for first time in post-verdict motions). Moreover, Dr.
    9
    Williams does not contend that the charge objection did not advise the trial court
    of the Casteel problem or that the proposed instruction was incorrect or confusing.
    50
    Benge asserted during the presentation of the evidence that Williams was
    improperly injecting a consent theory into the case.
    After the parties rested, the court held an informal charge conference.
    During the informal conference, Dr. Benge asked for the following instruction:
    You are instructed that in deciding whether any defendant was
    negligent, you cannot consider what the defendant told, or did not tell,
    the plaintiff about the resident physician being involved with the
    surgery.
    Williams responded, “It’s not an informed-consent case. It’s whether or not Dr.
    Benge acted properly when he didn’t do part of the surgery and let someone else
    do it. That’s what the case is about . . . It’s not an informed-consent case. It’s a
    negligence case.” In reply, Dr. Benge asserted that Williams therefore should have
    no objection to the instruction. When the court asked why the instruction was
    necessary, Dr. Benge responded that evidence had been presented on the consent
    issue. He further stated, “But the problem is the jury very well could focus on
    [informed consent] and could decide, ‘Boy, I wish they would have given Ms.
    Williams more information. She might not have allowed Dr. Giacobbe to be
    involved.’ That is informed consent, which isn’t in the case.” The trial judge stated
    that she would not give the instruction.
    During the formal charge conference, Dr. Benge objected to the broad-form
    liability question as follows: “[D]efendants object to Question Number 1,
    negligence, because the broad-form submission allows the jury to base its finding
    51
    on a violation of informed consent . . . .” The objection was overruled. In an effort
    to reduce the possibility that the jury would assign liability for failing to disclose
    the resident’s involvement, Dr. Benge requested the same instruction that he had
    requested during the informal charge conference. The requested instruction was
    refused.
    Dr. Benge specifically objected to the broad-form nature of the liability
    question and advised the trial court that a liability finding could be based on the
    informed consent theory that Williams presented. Subsequently, Dr. Benge offered
    an instruction that would have prevented the jury from finding negligence based on
    a failure to inform. While he did not cite Casteel, it was unnecessary for him to do
    so. Morrison, 381 S.W.3d at 536 (“Casteel error may be preserved without
    specifically mentioning Casteel.”); Thota, 366 S.W.3d at 691 (“[Appellant] did not
    have to cite or reference Casteel specifically to preserve the right for the appellate
    court to apply the presumed harm analysis . . . .”). His objection informed the trial
    court that the broad-form negligence question mixed general negligence and
    informed consent issues. His proposed instruction attempted to carve out the
    informed consent issue from the broad-form negligence question. Dr. Benge,
    therefore, apprised the trial court of the error “such that the court [had] the
    opportunity to correct the problem.” Burbage, 
    2014 WL 4252274
    , at *7; see also
    Thota, 366 S.W.3d at 690–91 (holding the charge error was sufficiently preserved).
    52
    And the instruction did so while allowing the jury to consider the evidence of Dr.
    Giacobbe’s inexperience: it only precluded a negligence finding based on what
    Williams was told about that experience. Thus, the jury could have relied on her
    experience not only in evaluating her conduct during the surgery, but also Dr.
    Benge’s supervision of her during the surgery. In short, Dr. Benge’s proposed
    instruction did not detract the jury from focusing on the claimed acts of negligence
    during and after the surgery.
    We conclude that Dr. Benge’s complaints were sufficient to alert the trial
    court to the potential deficiency in the jury charge that set up a Casteel problem,
    merging valid and invalid theories of liability into a single, broad-form liability
    question. See Morrison, 381 S.W.3d at 536 (holding in wrongful termination
    lawsuit that complaint that charge improperly lumped different employment
    actions together was sufficiently identified to preserve error even though employer
    did not state during charge conference that question mixed legally valid and invalid
    theories or, as phrased by intermediate appellate court, in Texas Commission on
    Human Rights v. Morrison, 
    346 S.W.3d 838
    , 847–48 (Tex. App.—Austin 2011),
    rev’d, 
    381 S.W.3d 533
     (Tex. 2012), “that it was concerned about legally invalid
    theories”). As the Texas Supreme Court has explained,
    There should be but one test for determining if a party has preserved
    error in the jury charge, and that is whether the party made the trial
    court aware of the complaint, timely and plainly, and obtained a
    53
    ruling. The more specific requirements of the rules should be
    applied . . . to serve rather than defeat this principle.
    State Dep’t of Highways & Pub. Transp. v. Payne, 
    838 S.W.2d 235
    , 241 (Tex.
    1992) (emphasis added); see also Thota, 366 S.W.3d at 690. We conclude that Dr.
    Benge preserved error in the jury charge.
    Having concluded that Dr. Benge preserved error, we turn next to whether
    the commingling of the valid and invalid theories was harmful error.
    F.    Casteel error requires reversal
    Williams contends that there was sufficient evidence for the jury to find that
    Dr. Benge or Dr. Giacobbe operated below the standard of care when one or the
    other perforated Williams’s bowel during surgery. Thus, she concludes, any error
    is harmless.
    When an invalid legal theory is mixed with one or more valid theories at
    trial and the jury is given only a broad-form liability question to which a proper
    objection is made, an appellate court will presume error because it cannot be
    determined if liability was based on a valid theory or solely on one of the invalid
    theories. See Casteel, 22 S.W.3d at 378–79; TEX. R. APP. P. 44.1(a)(2). The
    appellant is left unable to demonstrate the consequence of the trial court’s jury
    charge error because it is unclear on what the jury based its decision. Casteel, 22
    S.W.3d at 388.
    54
    Similar to the argument presented by Williams, the plaintiffs in Hawley
    argued that any jury charge error (which resulted because the jury could have
    reasonably—but erroneously—interpreted the charge to allow vicarious liability on
    the hospital for a physician who was not its agent) was harmless because the jury
    could have found negligence based on the nurses’ acts or omissions. 284 S.W.3d at
    864. But the Court held that the error was harmful, nevertheless, because it was
    impossible to determine whether the jury held the defendant hospital negligent
    based solely on the conduct of the physician or based on the conduct of the other
    individuals for whom the hospital had vicarious liability. Id. at 864–65. Thus, the
    Texas Supreme Court could not tell whether the jury thought the hospital was
    liable under a valid theory (negligence based on negligent acts by its nurses) or an
    invalid theory (negligence based on the negligent acts of the independent
    contractor physician). Id. At all times, the only “liability theory” was negligence;
    however, one of the two bases for a liability finding had no support under Texas
    law. See id. The Court presumed that the jury charge caused harm. Id. at 865.
    Similarly, the mixing of an invalid theory with a valid theory was harmful
    and required reversal in Romero. 166 S.W.3d at 227–28. There, the plaintiff sued a
    hospital for malicious credentialing of a surgeon who was a known drug abuser. Id.
    at 217–19. The plaintiff also claimed the hospital was negligent in delaying a blood
    transfusion during surgery. Id. The charge included a single, broad-form,
    55
    apportionment-of-liability question. Id. at 215. The jury found the hospital liable
    under both theories and assigned it a percentage of responsibility. Id. at 214–15.
    The Texas Supreme Court concluded, however, that there was no evidence of
    malicious credentialing. Id. at 224. It further found that the broad-form
    apportionment question made it impossible to determine how much of the
    hospital’s assigned responsibility was due to the impermissible malicious
    credentialing theory versus the allowed negligent delivery-of-blood theory. Id. at
    226. Citing Casteel, the Supreme Court explained, “Even if the jury could still
    have made the same apportionment of fault, the error in the question is
    nevertheless reversible because it effectively prevents Columbia from complaining
    on appeal that they would not have done so.” Id. The plaintiff could not avoid
    reversal by arguing that the jury might have reached the same apportionment of
    responsibility. Id.
    Likewise, the Court in Morrison rejected the plaintiff’s argument that, when
    an invalid theory is not directly submitted to the jury but is merely subsumed
    within broad language, “the mere possibility the jury may find liability based on an
    invalid theory does not constitute harm.” Morrison, 381 S.W.3d at 537. The Court
    explained: “The harm to [the Appellant] is not that the jury reached the wrong
    verdict, but rather that [the Appellant] has been prohibited from demonstrating on
    appeal that the jury’s verdict was based upon the invalid legal theory.” Id.
    56
    Here, Williams argued two alternative legal bases for finding Dr. Benge
    negligent: (1) either Dr. Benge or the resident physician for whom he was
    responsible were negligent during or after the surgery or, alternatively, (2) Dr.
    Benge failed to disclose Dr. Giacobbe’s role or experience beyond the statements
    contained in the signed disclosure forms and such failure was below the standard
    of care and, therefore, negligent. The first is a valid theory of liability, but the
    second is not. Williams repeatedly urged the jury to answer the liability question
    affirmatively on the basis of this invalid legal theory.
    From this record, we cannot say that the jury was not significantly
    influenced by the disclosure issue. We therefore sustain Dr. Benge’s second issue
    and must reverse.
    Conclusion
    Having sustained Dr. Benge’s second issue, we reverse and remand the case
    for a new trial. In doing so, we do not reach Dr. Benge’s third issue challenging the
    denial of periodic payments.
    All pending motions are denied as moot.
