BOWER, Chief Judge.
Norma Lund appeals the district court’s judicial review decision reversing
the workers’ compensation commissioner’s finding that her bilateral shoulder
injuries were caused by her employment with Mercy Medical Center. She claims
the district court misapplied the law and erroneously concluded there was a lack
of evidence to support a determination of medical causation. We reverse the
decision of the district court.
I. Background Facts and Proceedings.
Lund began working for Mercy Medical Center in December 2016 as a
sterilization processing technician.1 The job involved assembling the materials
needed for surgeries, placing the materials on large trays, placing the trays on
carts for sterilization, pushing the carts in and out of the sterilizer, and putting the
materials away. The job description provided by Mercy states the sterilization
processing technician position requires heavy work exerting up to sixty-five pounds
of push/pull (force to move frequently), lifting up to fifty pounds sometimes, lifting
up to forty pounds frequently, lifting up to twenty pounds constantly. Lund is five
foot three inches tall; the top shelf of the cart Lund placed trays on was above her
shoulder level. The trays had varying weights but were not supposed to exceed
twenty-five pounds. Vendor trays generally weighed more than in-house trays.
During the week, eight people were assigned to sterilization processing duties. On
weekends, two people were assigned.
1We will refer to Mercy Medical Center and its insurer, Indemnity Insurance
Company of North America, collectively as “Mercy.”

On Saturday, February 24, 2018, Lund worked her 3:00 p.m. to 11:30 p.m.
shift with no difficulties or complaints. Her coworker that day had recently had
dialysis, and Lund felt he was not helpful because of his physical limitations. On
Sunday, February 25, Lund worked the same shift with the same coworker.
Around 6:30 p.m., while lifting a vendor tray above her shoulder height, Lund felt
pain in the right side of her neck, radiating down into her chest. Both shoulders
felt tight and sore, but Lund continued to perform her duties through the rest of her
shift. Lund had Monday off. She returned to work on Tuesday with ongoing neck
and shoulder pain; a coworker helped with the heavy trays.
Lund continued to work and did not report her injury because she hoped it
would resolve itself. It did not.
On March 15, 2018, Lund sought medical care with Dr. Todd J. Harbach.
In a later letter to Mercy’s counsel, Dr. Harbach noted:
She was doing a lot of lifting to sterilize instruments for surgery, and
when I saw her, she was complaining of 50% cervical and 50%
bilateral arm pain. I specifically asked her if there was any trauma or
inciting incident at the time of my meeting with her, and she could not
specifically remember anything but rather just hurt after performing
all of the activities required of her job for several shifts.
Dr. Harbach diagnosed Lund with bilateral shoulder impingement and gave her
subacromial injections in both shoulders. He recommended physical therapy,
prescribed medications, and imposed work restrictions.
On March 16, Lund reported the injury to her supervisor. Lund was seen
that same date at Mercy Employee Health. The notes from that appointment state,
“Employee believes this is related to work activities.”
4
Lund was referred to Mercy One for evaluation. On March 19, Lund was
examined by Advanced Registered Nurse Practitioner (ARNP) Joanne Harbert.
ARNP Harbert noted, “States hurt herself lifting surgical pans.[2] She thought she
hurt her neck and went to see ortho and was injected both shoulders and told she
tore both rotator cuffs.” Harbert diagnosed Lund with acute bilateral shoulder
strain. Lund was placed on restrictions and ordered to go to physical therapy.
Neither the restrictions nor the physical therapy improved Lund’s condition.
An MRI performed on May 14, showed a full-thickness tear of the right
rotator cuff.3 Lund was referred by Mercy to an orthopedist.
Dr. Steven A. Aviles saw Lund on June 11 for right shoulder pain. Lund
stated she was working as a sterile processor and “hurt herself lifting surgical
pans.” His office notes state:
Onset: on 02/25/2018. Severity level is 3. It occurs constantly and
is stable. Location: right shoulder. The pain is aching. Context:
there is an injury. Trauma type: lifting, occurred at work. Hand
Dominance: right.
[Lund] is a 57-year-old woman who developed RIGHT
shoulder pain after working a weekend for sterile processing. She
states that she does not remember any clear injury, but that she had
significant pain the evening of Sunday after working the Saturday
and Sunday shift. She incidentally does complain of LEFT shoulder
pain.
Dr. Aviles diagnosed Lund with a right full-thickness rotator cuff tear. He
recommended surgery.
Lund continued to work with light-duty restrictions until June 18, when she
was removed from her job.
2The terms surgical pan and tray are interchangeable.
3Despite Lund’s complaint of pain in both shoulders, initially her treatment focused
on her right shoulder.
5
On July 9, Dr. Aviles responded to correspondence from Mercy’s counsel
and observed Lund could not recall a particular trauma or injury but described pain
as a result of increased workload. He did not believe the rotator cuff tears resulted
from work but an occurrence that is a “fairly normal phenomenon.” Mercy provided
no further treatment for Lund’s shoulder injuries.
On October 17, Lund petitioned for workers’ compensation benefits,
alleging she had suffered a body-as-a-whole injury as a result of “lifting at work.”
Lund sought treatment from Dr. Jeffrey P. Davick, who performed surgery
on her right rotator cuff on November 29. Dr. Davick’s notes state Lund “is a 57-
year-old female who injured the right shoulder at work. She was working at Mercy
Hospital in sterile processing. She was repetitively putting trays on a shelf above
shoulder height and felt a deep pull in her right shoulder.”
On March 18, 2019, ARNP Harbert responded to an inquiry from Mercy’s
counsel in which she described Lund’s intake sheet history of the injury as related
to “lifting heavy objects over shoulders on a cart.” ARNP Harbert replied she
“agree[d] with the Dr. Aviles medical opinion” described by counsel as “Ms. Lund’s
shoulder abnormalities were not caused by her work at Mercy Medical Center on
or about February 25, 2018.”
On March 19, an MRI of Lund’s left shoulder revealed a full-thickness tear
of the left rotator cuff. Dr. Davick performed surgery to repair the left rotator cuff
on April 2.
On April 26, Lund’s counsel summarized a meeting with Dr. Davick, which
Dr. Davick confirmed:
6
During our meeting, you did express the following opinions, all to a
reasonable degree of medical certainty;
1. You provided medical treatment for Ms. Lund relative to
injuries to her right and left supraspinatus (rotator cuff tears).
2. Your diagnosis is traumatic full thickness rotator cuff tears
at the insertion of the supraspinatus, both left and right.
3. That the nature of the work performed by Ms. Lund at Mercy
Medical Center, and specifically on the date of her injury, as
described in the enclosed narrative, as well as the description
presented to you by her during, your treatment, is consistent with the
type of activity resulting in rotator cuff/supraspinatus tears, and
therefore is considered a substantial and material causative factor in
both the right and left tears, and therefore more probable than not,
the cause of both the right and left rotator cuff tears.
On April 29, Dr. Aviles responded to a letter from Mercy’s counsel in which
he stated Lund “did not describe any specific trauma when she came to see me
on June 11, 2018.” He also noted:
[U]pon my review of [a May 14, 2018] MRI . . . there was adipose
architecture in the volume that was lost as a result of the
supraspinatus tear. This only develops as a result of chronic injury.
Furthermore, there was no evidence of acute trauma in the joint
including no blood in the joint or edema in the bone. I saw no
evidence of acute injury present. All evidence suggested that this
was a more chronic tear.
Dr. Aviles “reaffirm[ed] that the type of work activities as described by Norma Lund
are not considered a cause for the rotator cuff tear that I had seen on the MRI.”
On September 9, Dr. Aviles wrote a letter agreeing that if Lund had lifted
fifty pounds overhead repeatedly and at one point felt a pop with new onset of pain
that it could be the cause of the rotator cuff tear as seen on her MRI dated May 14,
2019.
Lund had not been released from Dr. Davick’s care at the time of the hearing
for workers’ compensation benefits held on October 31. At the hearing, Dr. Aviles’s
October 21 deposition was admitted. He agreed lifting could cause a rotator cuff
7
tear; however, he opined, “But the vast majority of people who have manual labor
lifting never have a rotator cuff tear. So lifting can, but not under chronic repetitive
stress for the most part. It’s usually an acute trauma.” Because Lund did not report
an acute trauma to him, he did not believe her injury was work-related.
Several witnesses testified about the weight of the trays and the number of
trays Lund lifted during her February 25 shift. Lund testified she lifted “at least” ten
vendor trays, which were heavier than others, and she estimated the trays were in
the thirty- to forty-pound range. It was when she lifted the vendor trays above
shoulder height that she felt the pain in her neck. Lund also testified she lifted
about 100 trays from the washer: “That’s what it felt like, at least a hundred.”
Cindy Jennings was the sterile processing supervisor and Lund’s direct
supervisor that day. She could not state what Lund’s workload was on February 25
but felt Lund overstated her workload. Jennings testified, “We do not have trays
that weigh up to forty pounds.” When asked how she knew, “Because we have a
scale. Joint Commission requires our trays to be twenty-five pounds.” She then
testified there are “some trays that weigh up to twenty-seven, twenty-eight pounds,
but we do not have forty-, fifty-pound trays.” On cross-examination, Jennings
agreed Lund “would be lifting trays classified as heavy over her head.”
Lund’s coworker testified the “vast majority” of the trays they lifted were in
the twenty-to-twenty-five pound range, some were thirty pounds, and he had
“never even lifted more than forty on that job.” He thought they had a “normal”
workload that weekend. Deposition testimony from other Mercy employees was
also admitted.
The deputy commissioner issued an arbitration ruling, finding:
8
the pans weighed no more than [twenty-five] to [twenty-seven]
pounds; that some trays were lifted at or above shoulder height and
that while most of the trays lifted at or above shoulder height should
have been light, [Lund] could have lifted vendor trays and placed
them in the uppermost part of the sterile carts, and that she could
have handled 100 trays during one shift.
The deputy also found:
Dr. Davick also agreed, based on [Lund’s] narrative of how the
incident occurred, that it was more probable than not her work was
the cause of both the right and left rotator cuff tears. [Lund’s]
narrative called the vendor trays heavy but did not define heavy by
weight. She stated that she was working three times as hard as a
typical workday and that she would be lifting these heavy vendor
pans on the tops of carts.
The deputy concluded Lund’s bilateral shoulder injuries resulted from her work and
manifested on or about February 25, 2018.4
On intra-agency appeal, Mercy argued Lund’s bilateral shoulder condition
was not work-related either as an acute injury or as a cumulative injury. The
commissioner, however, agreed with the deputy’s findings with this additional
analysis:
It is undisputed that [Lund] began experiencing symptoms during and
after her shift on February 25, 2018. Both at hearing and in her
deposition, [Lund] testified she “felt something”—like a “pop” or a
“pull”—in what she believed to be her neck as she was lifting a tray
above shoulder height during a busy shift. There is some dispute as
to whether [Lund] told several of her physicians about this “pop” or
“pull” sensation, but both Steven Aviles, M.D., and Jeffrey Davick,
M.D.—the competing experts in this case—were aware [Lund’s]
symptoms began while performing her work duties, which included
lifting pans.
Dr. Aviles, [Mercy’s] expert, initially opined there was “nothing
in the work that [Lund] described that would result in rotator cuff
tearing to her right shoulder.” He later explained that [Lund] “had
described activities consistent with normal activities of daily living.”
4The deputy found Lund had a preexisting shoulder condition that was “lit up or
aggravated on February 25, 2018, from lifting pans weighing up to [twenty-five]
pounds, some at or above shoulder height.”
9
However, as correctly noted by the deputy commissioner, there is
nothing in [Lund’s] regular day-to-day life that matches the work she
performed during her shifts with [Mercy], which included several
hours of lifting approximately 100 trays between [twenty-five] and
[twenty-seven] pounds on a repetitive basis—and, per her job
description, some occasional heavier lifting. In fact, when presented
with [Lund’s] deposition testimony about lifting trays weighing [fifty]
pounds on a repetitive basis, Dr. Aviles acknowledged that “it is
possible under these circumstances that lifting a [fifty]-pound pan
overhead could cause rotator cuff tearing.”
As discussed above, I affirmed the deputy commissioner’s
finding that [Lund’s] repetitive lifting involved pans that weighed
roughly [twenty-five] pounds—not [fifty] pounds. As such, I
recognize Dr. Aviles’ acknowledgment is not based on
circumstances that perfectly reflect [Lund’s] actual duties. This
acknowledgement, therefore, is only afforded nominal weight.
However, it remains a consideration, particularly because Dr. Aviles
failed to explain why [Lund] became symptomatic while performing
her work activities if these duties did not contribute to, or cause, her
condition.
In contrast to Dr. Aviles’ opinion, Dr. Davick opined that the
“nature of the work performed” by [Lund] . . . were “consistent with
the type of activity resulting in rotator cuff/supraspinatus tears.”
Dr. Davick then agreed that [Lund’s] work activity would be
considered “a substantial and material causative factor” in [her]
bilateral rotator cuff tears. I acknowledge Dr. Davick’s opinion—like
Dr. Aviles’ opinion—is not without its flaws. As correctly noted by the
deputy commissioner, the narrative contained in [Lund’s] Exhibit 2
on which Dr. Davick relied, at least in part, varied slightly from the
deputy commissioner’s findings of fact. Ultimately, however, Dr.
Davick’s opinion is most consistent with the onset of [Lund’s]
symptoms and the fact that [Lund] was asymptomatic before her shift
on February 25, 2018.
The commissioner concluded:
Though both expert’s opinions are flawed in some respect, I found
Dr. Davick’s opinion to be most consistent with [Lund’s] consistent
testimony and her work duties. Thus, considering the work [Lund]
was performing on February 25, 2018, along with [her] lay testimony
regarding the onset of her symptoms and Dr. Davick’s expert
testimony regarding causation, I find claimant satisfied her burden to
prove she sustained an injury to her bilateral shoulders on
February 25, 2018, that arose out of and in the course of her
employment.
10
Having found claimant sustained an acute or traumatic injury
on February 25, 2018, [Mercy’s] argument regarding their due
process rights is now moot.
Mercy sought judicial review in the district court, which reversed the
commissioner’s causation finding. Lund appeals.
II. Scope and Standard of Review.
A final judgment rendered by a district court under chapter 17A is reviewed
for errors of law. Iowa Code § 17A.20 (2020); Iowa R. App. P. 6.907. On judicial
review of an agency action, the district court may only interfere with the
commissioner’s decision if it is erroneous under one of the grounds enumerated in
section 17A.19(10). On appeal from the district court’s decision, we apply the
same standards to determine whether we reach the same conclusions as the
district court. Niday v. Roehl Transp., Inc., 934 N.W.2d 29, 34 (Iowa Ct. App.
2019). If we do, we affirm the district court’s decision; otherwise, we reverse. Id.“Our decision is controlled in large part by the deference we afford to
decisions of administrative agencies. Medical causation presents a question of
fact that is vested in the discretion of the workers’ compensation commission.”
Cedar Rapids Cmty. Sch. Dist. v. Pease, 807 N.W.2d 839, 844 (Iowa 2011).
III. Discussion.
In Pease, our supreme court noted:
Medical causation “is essentially within the domain of expert
testimony.” The commissioner, as trier of fact, has a duty to weigh
the evidence and measure the credibility of witnesses. The weight
given to expert testimony depends on the “accuracy of the facts
relied upon by the expert and other surrounding circumstances.”
Also, an expert’s opinion is not necessarily binding upon the
commissioner if the opinion is based on an incomplete history.
Ultimately, however, the determination of whether to accept or reject
11
an expert opinion is within the “peculiar province” of the
commissioner.
Id. at 845 (citations omitted).
The district court determined Dr. Davick “provided an inadequate threshold
for medical causation when he concluded that the consistency between [Lund’s]
work activities and a rotator cuff tear was the equivalent (‘therefore’) of those
activities being a substantial, material and probable cause of both tears.” The court
found Dr. Davick’s opinion flawed because he “equated consistency with
probability” and he was “provided no other factual basis upon which to conclude
that [Lund’s] work activities were the cause of her injuries.” From the decision, it
appears the district court read Dr. Davick’s opinion to mean the relationship
between the work activity and the bilateral rotator cuff tears was only a possibility.
Instead, the commissioner found Dr. Davick explained the causal connection
between the nature of the work—lifting heavy trays above shoulder height—with
the resulting rotator cuff tears and that it was “more probable than not, the cause
of both the right and left rotator cuff tears.” See Doe v. Central Iowa Health
System, 766 N.W.2d 787, 793 (Iowa 2009) (requiring evidence of the theory of
causation to be “reasonably probable—not merely possible, and more probable
than any other hypothesis based on such evidence.”).
“The rule is that expert testimony indicating probability or likelihood of a
causal connection is sufficient to generate a question on causation.” Hansen v.
Cent. Iowa Hosp. Corp., 686 N.W.2d 476, 485 (Iowa 2004). The nature of medical
causation will depend on probability and is often answered through the opinions of
experts. Pease, 807 N.W.2d at 845. The substantial-evidence standard directs
12
the court “to determine whether substantial evidence, viewing the record as a
whole, supports the finding actually made.” Id. (emphasis added). “Evidence is
not insubstantial merely because different conclusions may be drawn from the
evidence.” Id.
We are charged by statute and precedent to acknowledge “the
commissioner, as fact finder, is responsible for determining the weight to be given
expert testimony.” Id. at 850. And “[t]he commissioner is free to accept or reject
an expert’s opinion in whole or in part, particularly when relying on a conflicting
expert opinion.” Id. The commissioner considers the expert opinion “together with
all other evidence introduced bearing on the causal connection between the injury
and the disability.” Sherman v. Pella Corp., 576 N.W.2d 312, 321 (Iowa 1998)
(emphasis added). If an expert opinion alone cannot support a finding of
causation, the opinion can be coupled with other nonexpert testimony to support a
factual finding of causation. Nicks v. Davenport Produce Co., 115 N.W.2d 812,
815 (Iowa 1962). This is precisely what the commissioner did here. The
commissioner considered the competing expert opinions, recognized the
weaknesses in each, and ultimately found Dr. Davick’s opinion to be most
consistent with Lund’s “consistent testimony and her work duties.”
We have set out the evidence in some detail above. We find substantial
evidence supports the workers’ compensation commissioner’s decision, and the
district court erred in reversing the commissioner’s award. The judgment entered
by the district court is reversed and the commissioner’s decision is reinstated.
REVERSED.
