    I. INTRODUCTION
    RTG Medical appeals from orders of the Nebraska Workers’ Compensation Court
    awarding Janet Tompkins ongoing temporary total disability benefits and medical expenses to
    include treatment of complex regional pain syndrome and depression, along with penalties,
    attorney fees, and interest. On appeal, RTG Medical challenges the finding of a causal connection
    between Janet’s accident and claimed injuries; ordering of ongoing disability benefits despite
    alleged employability; and awarding of penalties, interest, and attorney fees. Because we find no
    error, we affirm.

    II. BACKGROUND
    1. JANET’S EMPLOYMENT, ORIGINAL INJURY, AND MEDICAL
    TREATMENT PRIOR TO COURT’S INITIAL AWARD
    On January 21, 2012, while Janet was employed by RTG Medical as a traveling nurse at a
    medical facility in Brookings, South Dakota, she slipped and fell on ice while walking outside the
    motel where she was being lodged. She landed on her outstretched left hand and wrist, her
    nondominant side, fracturing the left forearm. Janet did not hit her head or lose consciousness as
    a result of the fall. She denied having injuries beyond left forearm pain at that time.
    Janet was taken to a nearby emergency room that same day, where x rays revealed a left
    distal radius fracture. Closed reduction surgery was performed on the fracture, and the left arm
    was secured by a splint. Medical records note that Janet was taking depression medication at this
    time.
    Janet attempted a return to work the following workday, but was told by physicians at the
    medical facility after examination that she would be unable to work for approximately 12 weeks.
    They instructed her to go home. On that same day, Janet informed RTG Medical of her accident
    and injuries. Because Janet could not drive, her daughter transported Janet from Brookings to the
    daughter’s home in Wisconsin.
    Upon arriving in Wisconsin in January 2012, Janet was referred to Dr. Patrick Hall, an
    orthopedic surgeon. Hall examined Janet and performed an open reduction internal fixation of the
    left distal radius fracture. He expressed the opinion that Janet’s left arm/wrist injury was causally
    related to the accident. Hall referred Janet to an occupational therapist.
    In March 2012, Janet began attending occupational therapy. During these appointments, it
    was noted that Janet suffered from severe pain and substantial stiffness limiting her range of
    motion, all pertaining to the left forearm, wrist, and hand. The occupational therapist reported to
    Hall, expressing that the amount of pain experienced by Janet was reflective of complex regional
    pain syndrome.
    Janet ended this initial round of occupational therapy in May 2012 upon return to her
    Florida home. The occupational therapy discharge summary, signed by Hall, noted that Janet
    suffered from “pain well beyond proportion of injury.” X rays indicated that the facture was
    healing and bones were in alignment. It was observed that Janet received some relief through
    treatment, but not significant enough to really improve function. Hall “had questions” regarding
    whether Janet suffered from complex regional pain syndrome due to the severe pain and presence
    of swelling and discoloration. It was recommended that Janet continue seeing an orthopedic doctor
    and participate in further occupational therapy upon returning to Florida.
    Similar observations and diagnoses were made during Janet’s occupational therapy in
    Florida from June through August 2012. Janet continued to be limited to light activity due to severe
    pain in the left hand, forearm, and wrist. Her wrist remained very stiff and sensitive to the touch.
    Janet was unable to grasp or lift objects with her left hand and experienced shooting pain from the
    hand up into the forearm.
    During August 2012, Janet twice attempted to reenter the workforce. The first position was
    a one-day temporary job administering flu shots. The second position was at a school for severely
    -2-
    handicapped children. The record does not indicate how long this employment lasted. Janet
    testified that these positions required significant accommodations to account for her inability to
    use her left hand, and she felt unable to fulfill the assigned job duties. Regarding the second
    position, she noted her co-workers were not happy “because they were doing the work and I was
    getting paid.” Janet indicated during physical therapy that working made the pain worse. She
    voluntarily left both these positions.
    Janet met with Dr. Siddharth Shah, a neurologist, from August through November 2012.
    Once again, Janet complained of severe pain in the left forearm, along with experiencing an electric
    shock sensation. The muscles of her left hand were weak, with grip and sensation being
    diminished. Her left hand suffered significant stiffness, being unable to bend, squeeze, or extend
    this hand, or touch the left thumb and outer area of the left forearm. Janet denied any neck or
    radicular pains. Shah also conducted a neurological evaluation, including EMG and nerve
    conduction studies. The EMG showed possible C7-T1 radiculopathy and the nerve conduction
    studies were normal. Shah wrote a letter stating that Janet suffers from severe left hand pain and
    could not bear any weight. Shah recommended pain medications and continued therapy. Shah also
    referred Janet to a pain management doctor. However, Janet testified that she was unable to begin
    treatment with a pain management physician at that time because it was not authorized by RTG
    Medical.
    Shah formed the opinion, contained within a September 2012 medical report, that “with
    reasonable medical certainty and probability, (Janet’s) injuries, diagnoses, complaints, and
    treatment are casually (sic) connected to the slip and fall accident.” Shah initially made
    inconsistent reports regarding whether Janet had reached maximum medical improvement and
    suffered from complex regional pain syndrome. However, he later clarified that Janet had reached
    maximum medical improvement from a neurological standpoint, and she most likely has complex
    regional pain syndrome.
    Dr. Nicholas Strobbe, Janet’s primary care physician, examined her on October 11, 2012.
    His assessment noted “reflex sympathetic dystrophy”, which is another term for complex regional
    pain syndrome. Strobbe provided Janet with a return-to-work note on this date establishing a
    2-pound lifting restriction for the left hand.
    2. ORIGINAL WORKERS’ COMPENSATION COURT ORDER
    On November 13, 2012, following the parties’ stipulation of dismissal, the Nebraska
    Workers’ Compensation Court entered an order finding that Janet sustained personal injuries in an
    accident on January 21, 2012 arising out of and in the course of employment with RTG Medical.
    As a result, the court determined that Janet was entitled to workers’ compensation benefits. The
    court found Janet had not yet reached maximum medical improvement and was entitled to
    temporary total and/or temporary partial disability benefits beginning October 13, 2012 and
    continuing for so long as she is temporarily disabled. Further, the court found that pursuant to Neb.
    Rev. Stat. § 48-120 (Reissue 2010), Janet is entitled to future medical care from October 2, 2012
    going forward that is reasonable and necessary to treat her compensable injuries resulting from the
    accident.
    -3-
    3. RTG MEDICAL’S PETITION TO MODIFY
    AND JANET’S ANSWER
    On December 13, 2013, RTG Medical filed a petition to modify the court’s prior order
    granting Janet workers’ compensation benefits. RTG Medical alleged that Janet had sustained a
    material and substantial change in condition since entry of the original order, warranting a change
    or reduction in benefits owed by RTG Medical.
    On January 15, 2014, Janet filed an answer denying RTG Medical’s assertion. To the
    contrary, Janet alleged she experienced an increase in incapacity since entry of the original order,
    including damage to her left arm, complex regional pain syndrome, and impairment to the cervical
    spine. Further, Janet alleged that her work-related injuries have combined with, aggravated, or
    exacerbated her preexisting depression. Janet claimed to have not yet reached maximum medical
    improvement for the injuries resulting from her fall, and she remains temporarily totally disabled.
    She additionally asserted that RTG Medical failed to pay the proper amount of past benefits in a
    timely manner. Janet requested compensation and reimbursement for medical expenses,
    medical-related mileage, waiting-time penalties, attorney fees, and interest.
    4. TREATMENT OF PHYSICAL INJURIES/COMPLEX REGIONAL
    PAIN SYNDROME FOLLOWING ORIGINAL AWARD
    One year following the accident, Janet testified to being in considerable pain. Her left hand
    strength and range of motion remained minimal, and she was unable to lift objects or open doors
    with this hand.
    In January 2013, RTG Medical requested an independent medical examination of Janet by
    Dr. Thomas Greene. Greene responded to a questionnaire provided by RTG Medical, wherein he
    opined that Janet was not at maximum medical improvement of the left arm, and he recommended
    removing the internal fixation along with hand therapy.
    Upon referral by Strobbe, Janet began treatment with Dr. Edwin Colon, a pain management
    physician, in October 2013. Because this treatment was not authorized by RTG Medical, the cost
    was billed to Medicare and TriCare. Janet completed a form during her first appointment,
    explaining that the pain has negatively impacted her personality and life style, causing depression
    and considerable stress. Colon noted that Janet suffered from persistent pain and limited range of
    motion despite extensive treatment. Janet expressed to Colon that her pain and symptoms have
    gotten worse.
    Colon diagnosed Janet with complex regional pain syndrome of the upper limb. Colon
    noted that Janet experienced swelling of the left wrist, severe tenderness, electrical bolt pain, and
    atrophic changes of the thumb. Janet’s needs were noted to be beyond manageable by traditional
    means of pain medication and physical therapy. Because the symptoms and pain had worsened,
    Colon referred Janet back to Shah to repeat various testing.
    Janet returned to Shah in October 2013, who noted that Janet suffered from severe left arm
    complex regional pain syndrome, which was ongoing and worsening since the wrist surgeries. An
    MRI of Janet’s cervical spine was also conducted during this time, which revealed several
    conditions. Shah instructed Janet to follow up with Colon regarding pain management.
    -4-
    Following receipt of test results, Colon administered cervical epidural injections in early
    2014. These injections provided some relief, but the symptoms persisted and pain returned to the
    left upper extremity at high levels. Colon noted that Janet’s symptoms began to be more consistent
    with complex regional pain syndrome at this time. Colon subsequently administered nerve blocks
    to the front of the neck, which improved Janet’s upper extremity pain. Janet subsequently was able
    to reduce the amount of pain medication.
    Janet returned to Greene during this period, who recommended the removal of hardware
    contained within her wrist followed by therapy. Colon and Shah agreed with Greene that the
    internal fixation should be surgically removed.
    Shah opined at this time that Janet’s cervical issues were not connected to the accident.
    Colon later reached the same conclusion. However, Shah stated that Janet required continuing
    medical treatment for injuries resulting from the fall, including pain medications and physical
    therapy for her hand indefinitely into the future. On January 30, 2014, Shah formed the opinion
    that Janet was not at maximum medical improvement, and had permanent restrictions and
    limitations from the injury.
    In May 2014, Janet returned to Colon complaining of pain in the left wrist radiating to
    surrounding areas. Colon found her to be totally disabled at that time. Colon subsequently
    responded to a medical questionnaire, opining that Janet suffered from complex regional pain
    syndrome causally connected to the accident and resulting surgical intervention.
    Also in May 2014, Greene surgically removed the internal fixation hardware from Janet’s
    left wrist. However, Janet testified that this procedure caused the pain to increase, with electrical
    bolt sensations now shooting further up her arm.
    Janet followed up with Colon in June 2014 after the removal surgery, complaining of more
    pain and sensitivity at the surgical site. Examination of the left wrist and hand demonstrated
    numerous conditions, including weak range of motion, pain in movement, tenderness, poor grip
    strength, and significant sensitivity. Janet reported severe pain which negatively affected her sleep,
    personality, and stress levels, along with causing depression. Colon’s diagnosis continued to
    include complex regional pain syndrome of the upper limb.
    Janet returned to Greene in July 2014. Similar symptoms were reported by Janet and
    observed during examination. Greene later noted that Janet’s functional limitations and restrictions
    for use of the left hand were substantial, being capable of probably no more than sedentary use.
    Greene indicated that maximum medical improvement had not been achieved and Janet was not
    to use her left hand.
    In August 2014, Colon noted that Janet’s medications were not working as well, and any
    benefit achieved from nerve blocks was gone. Colon’s diagnosis continued to include complex
    regional pain syndrome of the upper limb. A couple weeks later, Janet followed up with Shah.
    Similar observations and findings were made, more tests were conducted, and a referral was made
    to Dr. Soliman, a neurosurgeon.
    In January 2015, Greene provided brief responses to a questionnaire from RTG Medical’s
    attorneys. Greene opined that Janet’s left distal radius fracture had been resolved. Greene was
    asked to confirm whether Janet currently has complex regional pain syndrome resulting from the
    accident, and to explain his opinion in detail. Greene responded as follows: “Does not. No clinical
    -5-
    evidence. Pain subjective and [l]oss of hand motion not physiologic.” Greene stated that Janet had
    reached maximum medical improvement, had “no restrictions,” and required no further medical
    treatment for injuries sustained in the accident. Also in January 2015, Shah provided a report
    addressing the results of a recent bone scan of the hand and wrist. Shah expressed that the scan
    results “do not support a neurovascular effect such as (complex regional pain syndrome).”
    In March 2015, Janet was evaluated by Soliman. After examining recent tests, Soliman
    noted that the symptoms did not appear to be related to the cervical spine, but rather associated
    with chronic wrist pain secondary to the severe fracture and resulting repair. Janet also filled out a
    patient evaluation form, expressing signs of physical pain and depression similar to prior reports.
    Janet was subsequently referred to Dr. Hashim, who inserted a spinal cord stimulator into
    Janet’s back for a trial period of three days in April 2015. Janet reported that the stimulator
    provided improvement and relief of pain. Hashim’s diagnosis included severe left complex
    regional pain syndrome of the upper limb. He recommended permanent placement of the
    stimulator.
    Janet followed up with Colon, Shah, and Soliman in the months leading up to trial. Colon
    continued to diagnose Janet with complex regional pain syndrome and continued to prescribe pain
    medications. Shah and Soliman similarly maintained a diagnosis of complex regional pain
    syndrome.
    Soliman explained that this syndrome is a “symptom complex and in the absence of an
    agreed gold standard multiple tests are necessary to verify the authenticity of this diagnosis.” Dr.
    Soliman opined that the injuries suffered in the work accident are causally connected to Janet’s
    current problems. Soliman further determined that Janet was not at maximum medical
    improvement for her work-related physical injuries. He recommended the spinal cord stimulator
    for treatment, as it has benefited many patients with the same condition.
    5. DIAGNOSIS AND TREATMENT OF DEPRESSION
    SUBSEQUENT TO ORIGINAL AWARD
    One year following the accident, Janet claimed to be suffering from depression and panic
    attacks as a result of being told she could never work as a nurse again, which she described as her
    “whole life.” As noted above, Janet reported depression to her physicians as she was treating for
    her physical injuries.
    Strobbe referred Janet for a psychiatric consultation on February 6, 2013. On May 6, 2013
    Strobbe responded to a medical questionnaire, opining that Janet’s current psychological condition
    was causally related to the accident and/or the accident caused aggravation of a preexisting
    psychological condition. Strobbe stated it was reasonable and necessary for Janet to be evaluated
    and treated by a psychiatrist. However, Janet was unable to see a psychiatrist at that time due to
    lack of authorization by RTG Medical.
    In an effort to have the psychiatric and pain management treatment authorized, Janet’s
    attorney sent RTG Medical’s attorney a letter in May 2013, which included Strobbe’s
    questionnaire responses regarding Janet’s psychological condition and the referral to Colon, a pain
    management physician. A follow-up letter was sent two months later, but approval was never
    -6-
    granted by RTG Medical for either treatment. On a similar note, as addressed below, RTG Medical
    made late disability benefits payments on three occasions.
    Janet began psychiatric treatment with Dr. Raghu Devabhaktuni in August 2013, which
    treatment was billed to Medicare and TriCare since RTG Medical did not authorize this treatment.
    Devabhaktuni noted in part the following conditions, observed during appointments and reported
    by Janet: depression, anxiety, panic attacks, frequent mood swings, manic episodes, trouble
    concentrating, poor sleep, impulsivity, impatience, irritability, anxiety, low self-esteem, and
    hopelessness.
    The death of Janet’s husband in 2004 and daughter in 2010 were topics of discussion during
    this treatment. Devabhaktuni noted that Janet complained of being under increased stress, and he
    also noted she had problems dealing with the losses of her husband and daughter. Janet testified to
    having depression and panic attacks after her husband’s death for a period of six months to a year.
    She “went back to work and tried to stay busy” during this period, and felt these psychological
    issues were resolved after his death. Similarly, Janet attested to having depression and panic
    attacks after her daughter’s death. Once again, she “went back to work right after,” noting that she
    worked a lot, which was therapeutic and helped her deal with these psychological issues. Janet
    claims to have never seen a psychiatrist or participated in individual counseling prior to the
    accident.
    Devabhaktuni’s diagnosis for Janet was “Major Depression Recurrent, Severe, Panic
    Disorder” and that her Axis IV was “severe.” As a result, Devabhaktuni recommended treatment
    in the form of supportive psychotherapy, stress management, and antidepressant medications. He
    also referred Janet to individual counseling. However, Janet was unable to participate in this
    counseling because the provider does not accept Medicare and it was not authorized by RTG
    Medical. Responding to a medical questionnaire, dated August 28, 2014, Devabhaktuni agreed
    that Janet’s mental health condition is causally related to the accident, and she has yet to reach
    maximum medical improvement for these mental health injuries.
    In February 2015, Dr. Michael Maher performed an independent psychiatric evaluation of
    Janet at the request of RTG Medical. Maher interviewed Janet and reviewed her medical records.
    First, Maher determined that Janet had “reached maximum medical improvement with regard to
    her psychological and psychiatric condition,” while noting that this conclusion “should not be
    interpreted as precluding the possibility that further treatment might result in a higher level of
    well-being.” Maher also opined that Janet had “no psychiatric restrictions with regard to her work.”
    Second, Maher noted that Janet’s physical and psychological condition are “deeply and
    fundamentally related,” and an improvement in her physical condition and reduction in pain will
    improve mental health substantially. Third, Maher found Janet’s depression to be related to three
    primary areas: physical injuries and associated disability, and resulting impact on work-life and
    self-esteem; chronic pain; and life experience and loneliness since the death of her husband. Maher
    identified the first area as being the most significant of the three. Lastly, Maher noted that
    “thorough and continuing vocational rehabilitation efforts” would likely benefit Janet.

    6. SUBSEQUENT TRIAL AND WORKERS’
    COMPENSATION COURT ORDERS
    On July 20, 2015, trial was held on the petition to modify and Janet’s answer asserting an
    increase in incapacity. The evidence concerning Janet’s medical history and treatment following
    the initial order in November 2012 is set forth above.
    On September 1, 2015, the court entered a Further Award. First, the court determined that
    Janet “carried her burden of proof and persuasion establishing that [she] suffers from complex
    regional pain syndrome as a result of the injury sustained to her left hand/arm.” The court reached
    this conclusion on the basis that the evidence presented by Janet, specifically the records of
    Soliman and Colon, was “simply more persuasive” than that offered by RTG Medical. The court
    additionally found that Janet is in need of further medical treatment, specifically spinal cord
    stimulation and pain management, as prescribed by Soliman. Therefore, the court determined that
    Janet had not yet reached maximum medical improvement for her physical injury.
    The court also found that Janet “suffered a mental injury and has yet to reach her true
    maximum medical healing from her psychiatric injury.” The court based this finding on the
    opinions offered by Devabhaktuni and Maher, along with “the specter of ongoing medication and
    recommended therapy” present in this case.
    Because Janet had not yet reached maximum medical improvement for all injuries
    sustained, including complex regional pain syndrome and an aggravation of preexisting
    depression, the court ordered the payment of ongoing temporary total disability benefits. Citing to
    the original order, establishing that RTG Medical was to pay for reasonable and necessary future
    medical care to treat all of Janet’s compensable injuries, the court further held that such treatment
    was to include not only the left upper extremity injury but also the resulting complex regional pain
    syndrome and psychological injury.
    The court rejected Janet’s claim of a cervical injury resulting from the accident. Janet does
    not challenge this finding on appeal, and we need not discuss it further.
    On December 10, 2015, a subsequent hearing was held before the court addressing Janet’s
    request for the imposition of penalties, interest, and attorney fees upon RTG Medical for late and
    denied payments. Exhibits were received in evidence, including affidavits by Janet and her
    attorney, along with attached medical records, a summary of paid benefits, and various attorney
    communications. Within these communications were attempts by Janet’s attorney to facilitate the
    late payment of medical expenses by RTG Medical and to gain authorization from RTG Medical
    for pain management and mental health treatment.
    On December 31, 2015, the court entered an order sustaining Janet’s request for an award
    of penalties, interest, and attorney fees. First, the court found that RTG Medical did not timely pay
    various weekly temporary total disability benefits; specifically, that RTG Medical made payments
    5 days late on two occurrences and 15 days late on another occasion. The court therefore ordered
    a waiting-time penalty of $1,160.25.
    Second, the court, having determined in its September order that Janet sustained the burden
    of linking depression to the accident and injuries sustained, found that RTG Medical wrongly
    refused to pay for mental health treatment. The court found this denial of payment to be baseless
    -8-
    up until Maher’s February 2015 report declaring Janet to be at maximum medical improvement
    for her mental injury. The court determined an award of $1,000 in attorney fees to be appropriate.
    The court chose to focus on the failure to authorize mental health treatment rather than pain
    management treatment in awarding attorney fees. Lastly, the award of penalties and attorney fees
    triggered an award of interest amounting to $8.02.
    RTG Medical subsequently perfected this appeal.
    III. ASSIGNMENTS OF ERROR
    RTG Medical assigns, summarized, restated, combined, and reordered, that the workers’
    compensation court erred in (1) finding Janet sustained complex regional pain syndrome resulting
    from the fall, (2) finding Janet’s ongoing depression is causally related to the fall, (3) ordering
    ongoing disability benefits despite proof of employability, (4) awarding penalties and interest for
    late payment of temporary total disability benefits; and (5) awarding attorney fees for delayed
    authorization of depression treatment.
    IV. STANDARD OF REVIEW
    A judgment, order, or award of the Workers’ Compensation Court may be modified,
    reversed, or set aside only upon the grounds that (1) the compensation court acted without or in
    excess of its powers; (2) the judgment, order, or award was procured by fraud; (3) there is not
    sufficient competent evidence in the record to warrant the making of the order, judgment, or award;
    or (4) the findings of fact by the compensation court do not support the order or award. Hynes v.
    Good Samaritan Hosp., 
    285 Neb. 985
    , 
    830 N.W.2d 499
    (2013).
    On appellate review, the factual findings made by the trial judge of the Workers’
    Compensation Court have the effect of a jury verdict and will not be disturbed unless clearly
    wrong. Armstrong v. State, 
    290 Neb. 205
    , 
    859 N.W.2d 541
    (2015). Neb. Rev. Stat. § 48-185
    (Reissue 2010) precludes an appellate court’s substitution of its view of the facts for that of the
    Workers’ Compensation Court if the record contains sufficient evidence to substantiate the factual
    conclusions reached by the compensation court. Davis v. Goodyear Tire & Rubber Co., 
    269 Neb. 683
    , 
    696 N.W.2d 142
    (2005). In workers’ compensation cases, an appellate court determines
    questions of law. 
    Armstrong, supra
    .
    As the trier of fact, the Workers’ Compensation Court is the sole judge of the credibility of
    witnesses and the weight to be given their testimony. Manchester v. Drivers Mgmt., 
    278 Neb. 776
    ,
    
    775 N.W.2d 179
    (2009).
    When testing the sufficiency of the evidence to support findings of fact made by the
    Workers’ Compensation Court trial judge, the evidence must be considered in the light most
    favorable to the successful party and the successful party will have the benefit of every inference
    reasonably deducible from the evidence. Olivotto v. DeMarco Bros. Co., 
    273 Neb. 672

    732 N.W.2d 354
    (2007).

    V. ANALYSIS
    1. CAUSAL RELATIONSHIP BETWEEN INJURIES AND ACCIDENT
    In order to recover under the Nebraska Workers’ Compensation Act, a claimant has the
    burden of proving by a preponderance of the evidence that an accident or occupational disease
    arising out of and occurring in the course of employment proximately caused an injury which
    resulted in disability compensable under the act. Manchester v. Drivers Mgmt., 
    278 Neb. 776
    , 
    775 N.W.2d 179
    (2009). A workers’ compensation award cannot be based on possibility or speculation,
    and if an inference favorable to the claimant can be reached only on the basis thereof, then the
    claimant cannot recover. Visoso v. Cargill Meat Solutions, 
    285 Neb. 272
    , 
    826 N.W.2d 845
    (2013).
    The causal connection between alleged injury, employment, and disability must be proven
    by competent medical testimony. See Money v. Tyrrell Flowers, 
    275 Neb. 602
    , 
    748 N.W.2d 49
    (2008). A proximate cause is a cause that produces a result in a natural and continuous sequence
    and without which the result would not have occurred. 
    Manchester, supra
    . The determination of
    causation is ordinarily a matter for the trier of fact. Hynes v. Good Samaritan Hosp., 
    291 Neb. 757
    ,
    
    869 N.W.2d 78
    (2015).
    (a) Complex Regional Pain Syndrome
    RTG Medical argues that the medical evidence contained in the record does not support a
    finding that Janet suffers from complex regional pain syndrome as a result of her fall.
    Upon our review of the record, considering the evidence in a light most favorable to Janet,
    we find the court did not err in concluding Janet suffered from complex regional pain syndrome
    (also referred to as reflex sympathetic dystrophy) causally resulting from the fall.
    In its Further Award, the trial court specifically noted the findings and opinions of Soliman
    and Colon that Janet suffered obvious autonomic disturbances of the hand and had improvement
    with sympathetic blocks, leading to a diagnosis of complex regional pain syndrome caused by the
    accident. The trial court weighed these opinions against opposing evidence, including the opinions
    of Shah and Greene and the results of a bone scan.
    The trial court noted that while Shah initially indicated that Janet had reached maximum
    medical improvement, Shah was careful to indicate that it was only from a “neurological
    standpoint” and he also indicated in his office records that Janet might well need a referral to a
    pain management doctor “to rule out a reflex sympathetic dystrophy.” We also note that Shah later
    determined that Janet did, in fact, suffer from severe left arm complex regional pain syndrome,
    which was ongoing since the wrist surgery.
    With regard to Greene’s opinion, the trial court noted that his opinion was set forth in a
    very brief handwritten response to questions posed by RTG Medical’s counsel, which response
    was “not detailed, but rather, largely conclusory in nature.” The court further stated, in reference
    to Greene’s opinion:
    To simply say that pain is subjective (a truism) and that [Janet’s] loss of hand motion is not
    physiologic fails to address [Janet’s] obvious autonomic disturbances of the hand such as
    temperature differences, cyanosis, hyperesthesia, dysesthesia and allodynia referenced by
    - 10 -
    Dr. Soliman in his report and verified by the multiple examinations performed by Dr.
    Colon.
    Consequently, the trial court gave very little weight to Greene’s opinion owing to the lack of a
    detailed opinion as requested by RTG Medical’s own counsel.
    Finally, the trial court acknowledged RTG Medical’s assertion that the bone scan of Janet’s
    hand and wrist did not support a diagnosis of reflex sympathetic dystrophy. Although Janet did
    not challenge the results of the bone scan, the court noted the evidence that there is no specific
    diagnostic test for complex regional pain syndrome and based upon Soliman’s other findings
    supporting the existence of the syndrome, it was not inclined to deem the bone scan determinative.
    The trial court was free to accept or reject opinions from the various expert witnesses. See
    Green v. Box Butte General Hosp., 
    284 Neb. 243
    , 
    818 N.W.2d 589
    (2012). We give due deference
    to the compensation court as sole judge of witness credibility and testimonial weight. There was
    clearly sufficient medical evidence adduced upon which the trial court could find the existence of
    complex regional pain syndrome and that such injury was causally connected to the accident.
    These factual findings were not clearly wrong and will not be disturbed on appeal.
    (b) Depression
    RTG Medical asserts that Janet’s depression was not causally related to the accident.
    Rather, RTG argues the depression resulted from the deaths of Janet’s husband and daughter.
    In addition to physical impairments, psychological injuries are compensable under the
    workers’ compensation scheme. Worline v. ABB/Alstom Power Int. CE Servs., 
    272 Neb. 797
    , 
    725 N.W.2d 148
    (2006). The burden is on the claimant to prove by a preponderance of evidence that
    his disability is the result of an accident arising out of his employment. 
    Id. Where the
    evidence is
    sufficient to permit the trier of fact to find that a psychological injury is directly related to the
    accident and the employee is unable to work, the employee is entitled to be compensated. 
    Id. A preexisting
    disease and an aggravation of that disease may combine to produce a
    compensable injury. Manchester v. Drivers Mgmt., 
    278 Neb. 776
    , 
    775 N.W.2d 179
    (2009). See,
    also, Heiliger v. Walters & Heiliger Electric, Inc., 
    236 Neb. 459
    , 
    461 N.W.2d 565
    (1990) (claimant
    entitled to award if burden of proof is satisfied, even though preexisting disability or condition
    combined with the present work-related injury to produce the disability for which the claimant
    seeks an award). By a preponderance of evidence a claimant must prove that the claimant’s
    employment proximately caused the claimed injury or disability and thereby correspondingly
    negate that a claimant’s condition existing independent of the claimant’s employment and before
    a work-related incident alleged to be a cause of the claimed disability is the sole cause of the
    disability for which compensation is sought. Heiliger v. Walters & Heiliger Electric, 
    Inc., supra
    .
    Upon our review, considering the evidence in a light most favorable to Janet, we find the
    trial court did not err in concluding Janet suffered from a mental health injury resulting from the
    fall.
    In its Further Award, the trial court specifically relied upon the opinions of Strobbe, Janet’s
    primary care physician, and Devabhaktuni, who both causally linked Janet’s current psychological
    condition to the work accident of January 21, 2012. Both doctors recommended psychiatric
    - 11 -
    treatment, including medication and counseling. Devabhaktuni determined that Janet had yet to
    reach maximum medical improvement with regard to her psychiatric condition.
    The court noted the independent psychiatric evaluation by Maher in early 2015 which
    acknowledged that while Janet’s life experiences including the loss of her husband contributed to
    her overall psychological condition, the “first and most significant is her physical injuries and
    associated disability as well as the effect on her work-life and self-esteem.” The court also noted
    Maher’s acknowledgement that “further treatment might result in a higher level in well-being”
    despite finding that she had reached maximum medical improvement. We also note that Maher
    specified that Janet’s physical and psychological condition are “deeply and fundamentally
    related.”
    After considering the foregoing opinions, the trial court concluded that Janet had sustained
    a psychological “insult” in the form of an aggravation of her preexisting depressive condition and
    she had not reached her true maximum healing from her psychiatric injury “according to the more
    persuasive medical evidence presented.”
    The court’s factual findings were not clearly wrong and will not be disturbed on appeal.
    2. ONGOING DISABILITY PAYMENTS
    RTG Medical argues that Janet’s lack of work restrictions and demonstrated ability to
    return to employment following the accident precluded an award of ongoing temporary total
    disability benefits pursuant to Neb. Rev. Stat. § 48-121(1) (Reissue 2010).
    An employee’s return to work does not in every case terminate an employee’s total
    disability from a work-related injury and does not preclude a finding that the employee’s total
    disability continues notwithstanding the return to work. Heiliger v. Walters & Heiliger Electric,
    Inc., 
    236 Neb. 459
    , 
    461 N.W.2d 565
    (1990). See, also, Godsey v. Casey’s Gen. Stores, Inc., 
    15 Neb. Ct. App. 854
    , 
    738 N.W.2d 863
    (2007).
    In a workers’ compensation case, total disability does not mean a state of absolute
    helplessness. It means that because of an injury, (1) a worker cannot earn wages in the same kind
    of work, or work of a similar nature, that he or she was trained for or accustomed to perform or (2)
    the worker cannot earn wages for work for any other kind of work which a person of his or her
    mentality and attainments could do. Money v. Tyrrell Flowers, 
    275 Neb. 602
    , 
    748 N.W.2d 49
    (2008).
    Based upon its detailed findings regarding Janet’s additional injuries as outlined above, the
    trial court rejected RTG Medical’s petition to modify to the extent that it requested a reduction in
    benefits owed to Janet. The court found that Janet is entitled to ongoing temporary total disability
    benefits as she has not yet reached maximum medical improvement for all of the injuries sustained
    in the accident. Upon our review, we find no error in this determination. Janet’s brief and
    unsuccessful attempts to return to employment do not preclude a finding that Janet’s disability
    continues notwithstanding these attempts to return to work. The record supports that Janet is unable
    to achieve regular employment. Further, contrary to the assertion of RTG Medical, both Shah and
    Strobbe imposed highly restrictive conditions on the use of her left hand.
    - 12 -
    3. AWARD OF PENALTIES AND INTEREST
    RTG Medical asserts that the trial court erred in awarding Janet a waiting-time penalty and
    interest for late payment of temporary total disability benefits.
    (a) Waiting-Time Penalty
    An injured worker’s entitlement to a waiting-time penalty is governed by Neb. Rev. Stat.
    § 48-125(1) (Reissue 2010), which provides in pertinent part:
    (1)(a) Except as hereinafter provided, all amounts of compensation payable under
    the Nebraska Workers’ Compensation Act shall be payable periodically in accordance with
    the methods of payment of wages of the employee at the time of the injury or death. Such
    payments shall be sent directly to the person entitled to compensation or his or her
    designated representative except as otherwise provided in section 48-149.
    (b) Fifty percent shall be added for waiting time for all delinquent payments after
    thirty days’ notice has been given of disability or after thirty days from the entry of a final
    order, award, or judgment of the compensation court . . .
    The Nebraska Supreme Court has summarized Neb. Rev. Stat. § 48-125(1) as requiring an
    employer to pay the 50-percent waiting-time penalty in the following circumstances: if (1) the
    employer fails to pay compensation within 30 days of the employee’s notice of a disability and (2)
    no reasonable controversy existed regarding the employee’s claim for benefits. Manchester v.
    Drivers Mgmt., 
    278 Neb. 776
    , 
    775 N.W.2d 179
    (2009) (citing Lagemann v. Nebraska Methodist
    Hosp., 
    277 Neb. 335
    , 
    762 N.W.2d 51
    (2009)).
    A reasonable controversy may exist (1) if there is a question of law previously unanswered
    by the appellate courts, which question must be answered to determine a right or liability for
    disposition of a claim under the Nebraska Workers’ Compensation Act, or (2) if the properly
    adduced evidence would support reasonable but opposite conclusions by the Nebraska Workers’
    Compensation Court concerning an aspect of an employee’s claim for workers’ compensation,
    which conclusions affect allowance or rejection of an employee’s claim, in whole or in part.
    Whether a reasonable controversy exists under Neb. Rev. Stat. § 48-125 is a question of fact.
    Manchester v. Drivers 
    Mgmt., supra
    .
    RTG Medical argues that the imposition of penalties for the late payment of temporary
    total disability benefits was error because it was investigating Janet’s third-party employment
    during this period. RTG Medical asserts that such employment created a reasonable controversy
    regarding Janet’s claim for benefits, thereby excusing RTG Medical’s late payments.
    Upon our review, we find there did not exist a reasonable controversy on the basis of
    employability which would excuse late payment of benefits by RTG Medical. As discussed in the
    previous section, Janet’s attempts to return to employment were brief and unsuccessful. And, these
    two unsuccessful attempts to return to work predated the compensation court’s original order
    entered upon the parties’ stipulation, which found Janet had not yet reached maximum medical
    improvement and ordered the payment of temporary total disability benefits. In addition, various
    work restrictions were placed upon her during the period that RTG Medical claims there was a
    reasonable controversy.
    - 13 -
    The trial court did not err in finding that there existed no reasonable controversy as to RTG
    Medical’s liability for payment of the temporary total disability payments, and the awarding of
    penalties pursuant to Neb. Rev. Stat. § 48-125 was not erroneous.
    (b) Interest
    Neb. Rev. Stat. 48-125(3) (Reissue 2010) provides for interest to apply to those weekly
    compensation benefits awarded which have accrued as of the date payment is made by the
    employer. The trial court calculated the amount of interest due on the delinquent disability
    payments to be $8.02. Upon our review, we find no error in the compensation court’s award of
    interest.
    4. AWARD OF ATTORNEY FEES
    RTG Medical argues that the imposition of attorney fees for the delayed authorization of
    mental health treatment was error. RTG Medical claims a reasonable controversy existed regarding
    the existence of causation linking Janet’s depression with the injury as opposed to the deaths of
    her husband and daughter, relying upon Maher’s opinion that Janet reached maximum medical
    improvement with regard to her mental condition.
    An injured worker’s entitlement to attorney fees is governed by Neb. Rev. Stat. § 48-125(2)
    (Reissue 2010), which provides in part:
    Whenever the employer refuses payment of compensation or medical payments subject to
    section 48-120, or when the employer neglects to pay compensation for thirty days after
    injury or neglects to pay medical payments subject to such section after thirty days’ notice
    has been given of the obligation for medical payments, and proceedings are held before the
    Nebraska Workers’ Compensation Court, a reasonable attorney’s fee shall be allowed the
    employee by the compensation court in all cases when the employee receives an award.
    The plain language of this statute allows an award of attorney fees if the employer is delinquent in
    paying medical expenses. VanKirk v. Cent. Cmty. College, 
    285 Neb. 231
    , 238, 
    826 N.W.2d 277
    ,
    282 (2013). This statute does not authorize the award of an attorney fee where there exists a
    reasonable controversy between the parties as to the entitlement of compensation. Beavers v. IBP,
    Inc., 
    222 Neb. 647
    , 
    385 N.W.2d 896
    (1986).
    The trial court found that while Maher’s February 17, 2015 report created a reasonable
    basis upon which to deny further psychiatric treatment after the date of the report, it determined
    that there was no reasonable basis for RTG Medical’s refusal to pay for mental health treatment
    prior to that date. The trial court relied upon the opinions of Strobbe and Devabhaktuni in making
    this determination. Upon our review, we find no error in the trial court’s determination. The record
    supported that, at least prior to February 17, 2015, the only medical opinions rendered established
    that Janet’s mental health condition was causally related to the accident, that she had not reached
    maximum medical improvement for this condition, and she was in need of further treatment. RTG
    Medical was notified of Janet’s mental health condition through letters sent by her attorney, in
    May 2013 and July 2013, specifically referencing Strobbe’s opinion that a causal connection was
    present between employment injury and depression, along with a recommendation for treatment.
    - 14 -
    There did not exist a reasonable controversy at that time regarding the cause of the aggravation of
    Janet’s preexisting depression which would excuse delayed authorization of treatment by RTG
    Medical.
    We conclude that the compensation court did not err in finding that RTG Medical had no
    reasonable basis for denying mental health treatment authorization prior to February 2015. The
    award of attorney fees on this basis was appropriate under Neb. Rev. Stat. § 48-125(2).
    VI. CONCLUSION
    Upon our review, we find that the workers’ compensation court did not err in its award of
    ongoing temporary total disability benefits and medical expenses along with penalties, interest,
    and attorney fees. Accordingly, we affirm.
    AFFIRMED.
