Defendant's Attorney: GINGER MOORE ROBEY

Description:

Jackson, MS - Personal Injury lawyer represented APPELLANT with a workers’ compensation benefits claim.

¶3. Duren worked as a general laborer for Effex, a temporary staffing agency. Effex
placed Duren at Luvata, a manufacturing company. On July 14, 2016, while building an airconditioning coil at Luvata, Duren stepped down from a table, fell down, and injured his
back.
¶4. Four days after his injury, Duren went to the Dr. Arenia C. Mallory Community
Health Center Inc. (MalloryHealth Center) in Lexington, Mississippi, reporting back and leg
pain. Duren was seen by Dana Roberts, a nurse practitioner. Roberts eventually referred
Duren to Dr. Graham Calvert, an orthopaedic surgeon in Jackson, Mississippi.
¶5. Dr. Calvert first started treating Duren in September 2016. Dr. Calvert ordered an
MRI of Duren’s lumbar spine, which indicated a disc herniation at L3-L4 and L4-L5. Dr.
Calvert recommended that Duren receive steroid injections, and he placed Duren on a light
sedentarywork restriction, noting that if Duren’s employer could not accommodate him, then
2
he should be off work until further notice.
¶6. Duren returned to Dr. Calvert in October 2016. Dr. Calvert’s notes from that
appointment reflect that Duren reported feeling significant relief after receiving the steroid
injections and that his leg pain had significantly improved. Duren reported that he still
suffered a little bit of back pain. Dr. Calvert kept Duren limited to modified work duties.
¶7. In December 2016, Duren followed up with Dr. Calvert. At his appointment, Duren
reported that the effect of his steroid injections had worn off and that he suffered continuous
pain down his left leg. Dr. Calvert compared Duren’s updated MRI results to the September
2016 MRI results and observed that the L4-L5 herniation was resolving and “appears
improved.” However, Dr. Calvert noted that the L3-L4 disc herniation had not significantly
changed since September and was now at a “symptomatic” level.
¶8. Based on Duren’s updated MRI results, Dr. Calvert performed an L3-L4
microdiscectomy on Duren in December 2016. At a follow-up appointment on March 10,
2017, Dr. Calvert reported that Duren’s pain caused by the L3-L4 disc herniation “has
completely gone.” Dr. Calvert placed Duren at MMI with a whole-body impairment rating
of three percent, and he released him to return to work with no restrictions.
¶9. Duren returned to work on March 14, 2017. After working for a few hours that day,
Duren informed his supervisor that he was in pain. Duren’s supervisor advised him to go see
his doctor. Duren attempted to make an appointment with Dr. Calvert, but he was
unsuccessful. Duren instead went to Mallory Health Center, complaining of numbness and
3
tingling in his left leg. Roberts prescribed Duren anti-convulsant and anti-inflammatory
medications to help with his pain.
¶10. Duren returned to work the next day, but after working several hours, he advised his
supervisor that he was again suffering pain. Duren reportedly did not show up for work on
March 16, 2017, and on March 17, 2017, Effex contacted Duren by telephone and terminated
his employment.
¶11. The record shows that the Employer/Carrier paid Duren temporary total disability
benefits at the rate of $332.37 per week from July 14, 2016, the date of his injury, through
March 10, 2017, the date that Dr. Calvert placed Duren at MMI and released him to return
to work without restrictions.
¶12. On April 5, 2017, Duren filed a petition to controvert alleging that he suffered a workrelated injury to his back, his left-lower extremity, and his body as a whole while working
for Effex. On April 14, 2017, the Employer/Carrier admitted that Duren suffered a
compensable injury to his back. The parties stipulated that Duren had an average weekly
wage of $498.47 at the time of the injury.
¶13. After filing his petition to controvert, Duren returned to the Mallory Health Center
complaining of low-back pain and left-lower extremity numbness and tingling. Roberts
prescribed Duren pain medication and referred himto a pain management specialist. Roberts
also recommended that Duren receive an MRI of his cervical, thoracic, and lumbar spine.
¶14. Duren filed a motion to compel medical treatment, requesting that the AJ compel the
4
Employer/Carrier to approve and pay for his pain management treatment and medications
prescribed by Roberts. Duren claimed that Roberts referred Duren to pain management for
his continued back pain and numbness and tingling in his leg but that the Employer/Carrier
denied authorization for the pain management referral. The record reflects an e-mail from
the Employer/Carrier’s counsel denying authorization of the referral for pain management.
In the e-mail, counsel explained that Dr. Calvert is Duren’s treating physician, and the pain
management referral was from a nurse practitioner at MalloryHealth Clinic and not from Dr.
Calvert. Counsel stated that as far as she knew, “Dr. Calvert has not indicated that pain
management is medically necessary.”
¶15. In July 2017, the AJ determined that an independent evaluation would be helpful, and
he ordered Dr. Philip Blount, a physical medicine and rehabilitation physician, to perform
an independent medical examination (IME) of Duren. Dr. Blount evaluated Duren and
issued his IME report. Dr. Blount agreed that Duren’s disc herniations at L3-L4 and L4-L5
were related to his fall at work in July 2016. Dr. Blount disagreed with Dr. Calvert’s threepercent whole-body impairment rating, explaining that he would instead assign an eightpercent whole-bodyimpairment rating because the three-percent impairment rating onlytook
into account Duren’s L3-L4 disc herniation and not his L4-L5 disc herniation. Dr. Blount
agreed that Duren reached MMI on March 10, 2017.
¶16. On November 11, 2017, the AJ entered an order denying Duren’s motion to compel
medical treatment. The AJ explained that Duren’s “request for pain management is hereby
5
denied as the provider who referred claimant to pain management is outside the scope of
medical providers in this claim, and pain management is also not reasonable and necessary
as opined by Dr. Philip Blount in his Independent Medical Examination report[.]” The AJ
also ordered Duren to undergo a comprehensive evaluation of his condition by Dr. Angela
Koestler, a psychologist.
¶17. In April 2018, Duren’s counsel requested that Dr. Blount clarify the opinions from his
IME report. In response, Dr. Blount issued an additional report clarifying his findings. Dr.
Blount opined that Roberts’s recommendation that Duren receive a post-surgery MRI to
diagnose the cause of his continued pain, as well as the prescribed pain medications, were
all reasonable and medically necessary to treat Duren’s work injury. Regarding Roberts’s
pain management referral, Dr. Blount stated that chronic pain from a work injury should be
managed by a medical professional trained in pain management, and he agreed with
transferring Duren from Roberts to a “higher level of care.”
¶18. In May 2018, Duren filed another motion to compel medical treatment, temporary
total disability benefits, and payment of medical bills. In this motion, Duren referenced Dr.
Blount’s report clarifying his opinions and opining that a post-surgery MRI and the pain
medications were reasonable and necessary to treat Duren’s work injury. Duren accordingly
requested that the AJ order the Employer/Carrier to pay for Duren’s medical bills from
MalloryHealth Center, asserting that this continued treatment was related to his work injury.
Duren also requested that the AJ order the Employer/Carrier to (1) approve and pay for the
6
past and future expenses of his pain medicine, as well as an evaluation and treatment pain
management, and (2) render temporary total disability benefits until Duren has been placed
at MMI by his pain management physician.
¶19. At the request of the Employer/Carrier, Dr. John Davis, a neurosurgeon, performed
an “Employer’s Medical Evaluation” on Duren. Dr. Davis performed his evaluation and
issued his report opining that as far as Duren’s disc herniation at L3-L4, he “indeed was and
remains at maximum medical improvement as of March 10, 2017.” Dr. Davis also testified
that he agreed with Dr. Calvert’s treatment protocol. Dr. Davis recommended a post-surgery
MRI of Duren’s lumbar spine to determine if there was any remaining L5 nerve root
compression.
¶20. On October 25, 2018, Duren underwent a lumbar MRI scan. Dr. Calvert and Dr.
Davis reviewed the updated MRI and issued a report detailing their findings. Neither doctor
found anything on the scan to explain Duren’s complaints of pain. Dr. Calvert recommended
“continued pain management, and/or physical medicine and rehab recommendations.” Dr.
Davis also performed a myelogram and post-myelogram CT scan on Duren to determine if
Duren suffered any L-5 nerve root compression, and after reviewing the scans, he found “no
evidence . . . of any nerve root compression at any level.”
¶21. In January 2019, Duren filed a third motion to compel medical treatment, total
temporary disability benefits, and payment of medical bills. After a hearing, the AJ entered
an order denying the motion on March 20, 2019. The AJ found that “[b]ased on the
7
overwhelming evidence from the medical specialists, [Duren] reached MMI on March 10,
2017,” and therefore Duren was not entitled to receive temporary total disability benefits
after that date. The AJ also found that the treatment and prescriptions from the nurse
practitioner at Mallory Health Center did not appear to be reasonable and necessary, and
therefore the Employer/Carrier was not responsible for payment of these treatments and
medications.
¶22. Duren filed a motion for reconsideration of the AJ’s March 20, 2019 order. After a
hearing, the AJ entered an order denying Duren’s motion for reconsideration.
¶23. On February 20, 2020, Duren went to Dr. Neil Sloan, an internal medicine specialist,
for an IME. Dr. Sloan prepared an IME report detailing his findings. In his report, Dr. Sloan
opined that Duren had reached MMI as of February 20, 2020, the day of his exam. Dr. Sloan
assigned Duren a fourteen-percent whole-person impairment rating. On March 2, 2020, Dr.
Sloan issued an addendum stating that Duren would be precluded fromreturning to work that
includes lifting twenty pounds, twisting, and bending or kneeling positions.
¶24. On June 16, 2020, the AJ held an evidentiary hearing on the merits of Duren’s
compensation claim. The issues in dispute included the nature and extent of temporary
disability attributable to the work injury; the extent of any resulting loss of wage-earning
capacity, and Duren’s entitlement to any permanent disability benefits; and Duren’s
entitlementto ongoing medical treatment pursuant to the MississippiWorkers’Compensation
Act and what treatment, if any, is reasonable and necessary treatment.
8
¶25. At the hearing, the AJ heard testimony from Duren and his wife, LaWanda Duren.
The parties submitted Duren’s medical records and IME reports into evidence, as well as the
depositions of Dr. Blount, Dr. Calvert, and Dr. Davis. The AJ also considered the IME
report issued by Dr. Koestler, the psychologist, in which Dr. Koestler opined that from a
psychological standpoint, Duren had no impairment or restrictions from his July 2016 work
injury and recommended that returning to “some type of employment” would be beneficial
for Duren.
¶26. On September 2, 2020, the AJ entered a final order denying Duren’s claim for
permanent partial disability and payment of additional temporary total disabilitybenefits and
medical expenses. Addressing the issue of permanent partial disability benefits and loss of
wage-earning capacity, the AJ recognized that Duren must first show that he suffered a
permanent disability, and this disability must be supported by credible medical testimony.
The AJ acknowledged that Dr. Calvert returned Duren to work without any restrictions, and
that neither Dr. Blount nor Dr. Davis disagreed with Dr. Calvert’s assessment that Duren
could return to full-duty work. The AJ also found it “telling” that when Dr. Calvert released
Duren to return to work, Duren expressed that he did not want to return to work and
“catastrophicized” his pain. The AJ noted Dr. Calvert’s testimony that he felt that Duren was
malingering. The AJ also acknowledged that Dr. Blount felt that Duren could return to his
prior activity level without any increased risk and that Dr. Davis found no evidence of any
structural abnormality that was consistent with Duren’s subjective complaints of pain. The
9
AJ accordingly found that Duren failed to meet his burden of proving that his work injury
resulted in a permanent disability causing him to suffer a loss of wage-earning capacity, and
he therefore denied Duren’s claim for permanent partial disability benefits.
¶27. The AJ also determined that Duren was only entitled to temporary total disability
benefits from July 15, 2016, until March 10, 2017, the date Duren was “clearly” placed at
MMI. The AJ specified that these benefits would be made at the compensation rate of
$332.33 per week. The AJ ordered that the Employer/Carrier would receive credit for any
disability payments previously made.
¶28. As to Duren’s claim seeking payment for continued medical treatment, the AJ ruled
that Duren was entitled to continued reasonable and necessary treatment related to the work
injury. However, the AJ reiterated his prior finding that the treatment, medications, and pain
management referrals provided by Mallory Health Center after March 14, 2017, were not
reasonable and necessary and therefore were not the responsibility of the Employer/Carrier.
¶29. Duren appealed from the order of the AJ to the Commission, and on March 4, 2021,
the Commission affirmed and adopted the AJ’s September 2, 2020 order. Duren now
appeals.
STANDARD OF REVIEW
¶30. In workers’ compensation cases, the Commission is the ultimate finder of fact.
Walmart Assocs. Inc. v. Cauley, 321 So. 3d 1216, 1227 (¶61) (Miss. Ct. App. 2021). “Our
scope of review in workers’ compensation cases is limited to a determination of whether the
10
decision of the Commission is supported by substantial evidence.” Id. at (¶62). “We will
only reverse the decision of the Commission if it is clearly erroneous and contrary to the
overwhelming weight of the evidence.” Id.
¶31. In the case before us, “the Commission’s order affirmed the AJ’s order without
additional analysis.” Mabus v. Mueller Indus. Inc., 205 So. 3d 677, 682 (¶21) (Miss. Ct.
App. 2016). In such cases, “this Court will examine the findings of fact made by the AJ.”
Id. We “then look[] to the AJ’s order for determination of the underlying issues.” Id.; see
also Cauley, 321 So. 3d at 1227 (¶61) (“When the Commission accepts the findings and
conclusions of the administrative judge, this Court reviews those findings and conclusions
as those of the Commission.”). We review the Commission’s application of the law de novo.
Gregg v. Natchez Trace Elec. Power Ass’n, 64 So. 3d 473, 475 (¶9) (Miss. 2011).
DISCUSSION
I. Permanent Partial Disability and Loss of Wage-Earning Capacity
¶32. On appeal, Duren argues that the Commission erred in finding that he sustained no
permanent partial disability or loss of wage-earning capacity. Duren maintains that he
submitted sufficient evidence to show that he suffered a permanent disability, and he claims
that the AJ did not give proper weight to Duren’s medical evidence. Duren asserts that in
making his determination, the AJ improperly gave more weight to the medical evidence and
opinions of Dr. Calvert and Dr. Davis. Duren also argues that because his employment at
Effex was terminated due to his work-related injury, and he has been unable to earn the
11
wages that he was receiving at the time of his injury in the same or other employment, the
Commission erred in finding that he suffered no loss of wage-earning capacity.
¶33. The Mississippi Workers’ Compensation Act provides compensation to an employee
“for disability . . . from injury . . . arising out of and in the course of employment, without
regard to fault as to the cause of the injury[.]” Miss. Code Ann. § 71-3-7(1) (Rev. 2021).
Mississippi Code Annotated section 71-3-3(i) (Rev. 2021) defines “disability” as “incapacity
because of injury to earn the wages which the employee was receiving at the time of injury
in the same or other employment, which incapacity and the extent thereof must be supported
by medical findings.” (Emphasis added). The Mississippi Supreme Court has clarified that
“[d]isability comprises (1) an actual physical injury; and (2) loss of wage-earning capacity.”
Gregg, 64 So. 3d at 475 (¶9) (internal quotation mark omitted). “In order to meet the
definition of disability, the claimant must not be able to obtain work in similar or other jobs,
and the claimant’s unemployabilitymust be due to the injury in question.” Smith v. Johnston
Tombigbee Furniture Mfg. Co., 43 So. 3d 1159, 1165 (¶19) (Miss. Ct. App. 2010). The
claimant bears the burden of proving both an actual physical injury and loss of wage-earning
capacity. Weathersby v. Miss. Baptist Health Sys. Inc., 195 So. 3d 877, 883 (¶24) (Miss. Ct.
App. 2016) (citing Gregg, 64 So. 3d at 476 (¶11)).
¶34. Relevant to our discussion, the supreme court has stated that “[o]ne first must find that
the claimant has a disability as defined by statute before analyzing the loss of wage-earning
capacity.” Lott v. Hudspeth Ctr., 26 So. 3d 1044, 1049 n.1 (Miss. 2010). While both parties
12
agree that Duren suffered an injury, “that injury must rise to the level of a disability before
it is compensable.” Id. at (¶18). To determine the extent of Duren’s disability in the case
before us, “[t]his Court must look to the medical evidence.” Mabus, 205 So. 3d at 683 (¶25).
¶35. At the hearing on the merits of Duren’s claim, the AJ heard testimony from Duren and
his wife, LaWanda Duren. The following medical exhibits were admitted into evidence: the
depositions and medical reports from Dr. Calvert, Dr. Blunt, and Dr. Davis; the medical
records from Mallory Clinic; the IME reports from Dr. Sloan and Dr. Koestler; and the
return-to-work slips from Dr. Calvert and Mallory Health Center. The record shows that in
July 2016, Duren fell at work and injured his back. Four days after his fall, Duren presented
himself to Nurse Practitioner Roberts at Mallory Health Center, complaining of back pain.
Roberts referred Duren to Dr. Calvert. Duren’s first appointment with Dr. Calvert was on
September 6, 2016. At the appointment, Duren complained of low-back pain that radiated
down his left leg and lower thigh, along with what Dr. Calvert described as a “very
straightforward left L5 radiculopathy.” Dr. Calvert ordered an MRI of Duren’s lumbar spine.
¶36. On September 9, 2016, Duren returned to Dr. Calvert for the results of the MRI. Dr.
Calvert testified that the MRI results showed a L3-L4 disc herniation impinging upon the
nerve, as well as a disc herniation at L4-L5. Dr. Calvert recommended physical therapy and
steroid injections as treatment. Dr. Calvert also restricted Duren to light sedentarywork with
a ten-pound lifting restriction. Dr. Calvert noted that if Duren’s employer could not
accommodate him, then Duren should be off work until further notice.
13
¶37. Duren followed up with Dr. Calvert on October 25, 2016. According to Dr. Calvert’s
notes from this appointment, Duren reported that he felt “significant relief” after his steroid
injections. Dr. Calvert noted that Duren still suffered “a little bit of back pain” with L5
radiculopathy, but he reported that Duren’s “leg pain is significantly improved.” After
examining Duren, Dr. Calvert found that Duren had a normal gait and a normal motor,
sensory, and reflex neurologic exam. Dr. Calvert kept Duren at modified work duty with
instructions to follow up in six weeks.
¶38. Duren returned to Dr. Calvert for a follow-up appointment on December 1, 2016. At
this appointment, Duren complained that his pain had worsened and that the steroid injection
had worn off. Dr. Calvert testified that at the December 2016 visit, Duren “was very
symptomatic over the L3 dermatologic pattern.” Dr. Calvert explained that Duren’s “pain
pattern changed from that of an L5 radiculopathy to a very straightforward L3
radiculopathy.” Dr. Calvert ordered a repeat MRI of Duren’s lumbar spine.
¶39. According to Dr. Calvert, the December MRI results showed that Duren’s L3-L4 disc
herniation was bigger compared to the image from the September 2016 MRI. However,
Duren’s L4-L5 disc protrusion had improved. Dr. Calvert explained that Duren still had a
“slight protrusion” at L4-L5, but “it was not as . . . big as the previous protrusion” shown on
the September 2016 MRI. Dr. Calvert testified that after viewing the December 2016 MRI
images and performing an evaluation on Duren, he determined that Duren’s L4-L5 disc “was
not an issue anymore.” Dr. Calvert testified that because Duren’s L3-L4 disc herniation
14
“looked worse” on the December 2016 MRI than it did on the September 2016 MRI, he
decided to perform a left L3-L4 microdiscectomy on Duren.
¶40. On December 12, 2016, Dr. Calvert performed a microdiscectomy on Duren. Duren
returned for a follow-up visit on December 27, 2016. Dr. Calvert testified that at that visit,
Duren “state[d] his radiating leg pain was gone,” but he complained of numbness and
weakness in his thigh. Dr. Calvert testified that complaints of numbness and tingling two
weeks after surgery is normal because the nerve needs time to recover.
¶41. Dr. Calvert saw Duren again on January 27, 2017, approximately six weeks after his
surgery. Dr. Calvert testified that at this appointment, Duren informed him that his leg still
hurt, but when Dr. Calvert questioned Duren about the pattern of the pain or where the pain
was located, Duren’s explanation “did not follow any specific dermatologic pattern.” Dr.
Calvert explained that Duren stated that his pain “was really over the whole leg. He was just
like, ‘My whole leg hurts.’” Dr. Calvert testified that in his opinion, “[i]t didn’t really make
sense from an anatomic standpoint or from an injury standpoint or from a nerve root
impingement standpoint what was causing the leg pain or if the leg pain was real, or if
[Duren] was just exhibiting some odd behavior because he wasn’t quite ready to go back to
work.” Dr. Calvert explained that “most people at six weeks from a microdiscectomy are
completely returning to all normal activities and have no leg pain.” At that point, Dr. Calvert
recommended that Duren receive physical therapy.
¶42. Dr. Calvert confirmed that Duren did attend physical therapy, and that when Duren
15
returned to see Dr. Calvert on March 10, 2017, Duren reported that he was better. During
the March 10, 2017 appointment, Dr. Calvert also noted that Duren’s L3 nerve root
compression was completely resolved and that Duren was pain-free. Dr. Calvert prescribed
Duren a pain medication, as well as anti-inflammatory medications, for limited use if Duren
developed any muscle pain upon returning to work. Dr. Calvert concluded that Duren
reached MMI on March 10, 2017, and he assigned Duren a whole-body impairment rating
of three percent. Dr. Calvert testified that his three-percent impairment rating was
“generous.” Dr. Calvert released Duren to return to work with no restrictions, and he
instructed that no follow up was necessary unless Duren developed a new disc herniation.
¶43. Regarding pain management, Dr. Calvert testified that he did not feel that a pain
management referral was reasonable or medically necessary at that point because Duren was
not having a lot of pain, if any pain at all. As for Duren’s prior L4-L5 nerve compression,
Dr. Calvert testified that Duren never complained of pain over an L5 dermatologic pattern
after the September 9, 2016 appointment.
¶44. Dr. Calvert stated that he was surprised to hear that four days after he assigned Duren
at MMI, Duren sought treatment from Roberts at Mallory Health Center for back and leg
pain. According to Dr. Calvert, at the March 10, 2017 appointment, Duren’s leg pain was
gone.
¶45. Dr. Calvert testified that “from the get-go,” Duren “made it pretty clear” that he did
not want to go back to work at his former job. Dr. Calvert said he was concerned that Duren
16
was “malingering” due to his “catastrophicized” pain complaints. Dr. Calvert testified that
Duren’s complaints and behavior were consistent with what he has seen from other patients
who “utilize [Workers] Comp and are malingering,” explaining that he has seen that type of
behavior “a lot.”
¶46. Duren’s medical records from Mallory Health Center show that on March 14, 2017,
the same day he returned to work without restrictions, he went back to the health clinic,
complaining of back and leg pain and left-leg numbness and tingling. The records show that
Duren had an abnormal gait and that he walked stiffly and slowly. Roberts prescribed Duren
medications to relieve his pain. Duren returned to Mallory Health Center in April 2017 and
October 2017, both times complaining of back and leg pain and left-leg numbness and
tingling. At these appointments, Roberts prescribed Duren more medications to relieve his
pain, and she instructed him to follow up with Dr. Calvert. At Duren’s request, Roberts also
referred Duren to a pain management specialist.
¶47. Dr. Blount, a physical medicine and rehabilitation physician, performed an IME of
Duren in September 2017. In his IME report, Dr. Blount acknowledged Duren’s “well
documented work injury,” and he opined that Duren’s multiple-level disc herniations (L3-L4
and L4-L5) were related to his fall at work on July 14, 2016. After examining Duren and
reviewing his medical records, Dr. Blount reported that he disagreed with the three-percent
whole body impairment rating assigned by Dr. Calvert. Dr. Blount stated that he would
instead assign an eight-percent whole-body impairment rating, explaining that the three17
percent impairment rating only took into account Duren’s L3-L4 disc herniation and not his
L4-L5 disc herniation. Dr. Blount agreed, however, that Duren reached MMI on March 10,
2017.
¶48. During Dr. Calvert’s deposition, he reviewed Dr. Blount’s IME report and testified
that he agreed with Dr. Blount’s whole-body impairment rating for Duren of eight percent
based on the rationale that Duren had two disc herniations rather than one. Dr. Calvert
testified that he thought a cumulative impairment rating of eight percent was “appropriate.”
He explained that when he assigned the three-percent impairment rating, he was referring to
the L3-L4 disc, and he was not thinking about the L4-L5 disc. Dr. Calvert acknowledged
that although he did not perform surgery on the L4-L5 disc, he did treat Duren for pain
stemming from that disc herniation. When questioned further, Dr. Calvert stated that he
would have given the L3-L4 disc a three-percent impairment rating and the L4-L5 disc a
three-percent impairment rating, for a cumulative impairment rating of six percent. Dr.
Calvert opined that a six-percent whole-bodyimpairmentratingwould be “more appropriate”
than an eight-percent impairment rating.
¶49. Dr. Blount testified that when he examined Duren for the IME in September 2017,
Duren was not pain free. Dr. Blount suggested a post-surgery MRI with contrast to assess
whether Duren has a recurrent disc herniation or scar formation from the surgery. Dr. Blount
stated he believed that when a patient has ongoing complaints after surgery, ordering a repeat
MRI with contrast “would be [the] standard of care.”
18
¶50. In September 2018, Dr. John Davis performed an Employer’s Medical Evaluation on
Duren, per the Employer/Carrier’s request. After examining Duren and reviewing his
medical history and records, Dr. Davis issued his report. Dr. Davis stated that Duren suffered
a work-related injury to his lumbar spine that involved two levels: L3-L4 and L4-L5. Dr.
Davis opined that as far as Duren’s lateral disc herniation at L3-L4, he “indeed was and
remains at maximum medical improvement as of March 10, 2017.” Dr. Davis also testified
that he agreed with Dr. Calvert’s treatment protocol of Duren.
¶51. Dr. Davis opined that the ongoing pain Duren complained of in his low back,
consistent with the L5 nerve root, “is directly causally related” to his work injury. Dr. Davis
explained that from a radiculopathy perspective, Duren “is left with almost exclusively L5
(or SI) distribution symptoms.” Dr. Davis agreed that an MRI of Duren’s lumbar spine was
“reasonable, appropriate, and needed” to determine “whether there is any significant or
persistent ongoing left-sided L5 nerve root compression.”
¶52. After reviewing Duren’s updated MRI and CT scans from October 2018, Dr. Davis
determined that the scans showed no evidence of any structural abnormality that was
consistent with or fit with Duren’s ongoing subjective complaints of pain. Dr. Davis reported
that he did not see any residual herniated disc at L3-L4, and he determined that “the issues
at L3-L4 are largely moot certainly from a surgical perspective.” Dr. Davis also stated that
“[m]ost importantly, on the left side at L4-L5, there is not a hint of a left L5 nerve root
compression.”
19
¶53. Dr. Calvert also reviewed the October 2018 MRI results, and he provided a report
stating that the MRI results revealed “scar tissue, granulation tissue around the exiting left
L3 nerve root consistent with postoperative changes.” Dr. Calvert stated that “[t]here is a
clear delineation between this scar tissue and the disc margin[,]” and he found that “[t]his
does not appear to be a recurrent disc herniation or free fragment.” Dr. Calvert stated that
he found nothing on the MRI that would warrant a revision surgery or a change in Duren’s
work status. Dr. Calvert also stated that the new MRI “does not shed any light or
explanations” for Duren’s continued complaints of pain.
¶54. In his final order, the AJ found that Duren “failed to meet his burden of proof that his
work injury resulted in a permanent disability causing him to suffer a loss of wage[-]earning
capacity,” and the AJ denied Duren’s claim for permanent partial disability benefits. The
AJ’s order reflects that in making his decision, he relied “most heavily” on the opinion of Dr.
Calvert, as Duren’s treating physician. The AJ found that “for the most part, Dr. Calvert’s
opinions are supported by the opinions of Dr. Blount, Dr. Davis, and Dr. Koestler,” while the
medical opinions of Roberts and Dr. Sloan were “out of line” with the opinions of the other
doctors. The AJ explained that he gave “little, if any, weight” to Roberts’s medical opinion,
because the AJ had previously entered an order finding that her treatment of Duren was not
reasonable or necessary. The AJ also stated that he gave “little weight” to the opinions of
Dr. Sloan because Dr. Sloan did not see Duren until February 20, 2020, and Dr. Sloan failed
to comment on the appropriateness of any of the treatments or opinions of Duren’s previous
20
physicians. Dr. Sloan’s report also does not reflect whether he reviewed any records or
findings from Dr. Davis or Duren’s most recent MRI or CT scan.
¶55. After our review, we find that the record contains substantial credible evidence to
support the Commission’s determination that the medical evidence in this case did not
support a finding of a permanent impairment. Dr. Calvert concluded that Duren reached
MMI on March 10, 2017, and he released Duren to work without any restrictions. Dr. Davis
and Dr. Blount performed their own examinations of Duren, and the record shows that they
did not disagree with Dr. Calvert’s findings as to MMI and work restrictions. Additionally,
Dr. Calvert and Dr. Davis reviewed Duren’s most recent MRI and found nothing on the scan
to explain Duren’s ongoing complaints of pain. We recognize that “subjective complaints
of debilitating pain unsupported by any medical proof of an underlying physical cause may,
if found credible by the finders of fact, support a claim for disability.” Wagner v. Hancock
Med. Ctr., 825 So. 2d 703, 706 (¶11) (Miss. Ct. App. 2002). However, the AJ did not find
Duren’s subjective complaints of pain to be credible.
¶56. As to Duren’s claim that the AJ improperly gave more weight to the medical
testimony and evidence provided by Dr. Calvert and Dr. Davis, this Court has held that
“where there is conflicting medical testimony, the Commission has the responsibilityto apply
its expertise and determine which evidence is more credible.” Weathersby, 195 So. 3d at 882
(¶21). Accordingly, “wheremedical expert testimonyis concerned, the [s]upreme [c]ourt has
held that whenever the expert evidence is conflicting, the Court will affirm the Commission
21
whether the award is for or against the claimant.” Id. (quoting Raytheon Aerospace Support
Servs. v. Miller, 861 So. 2d 330, 336 (¶13) (Miss. 2003)).
¶57. In addition to medical evidence, “[a]nother consideration in determining whether a
claimant has a disability is her wage-earning capacity.” Lott, 26 So. 3d at 1049 (¶16). “A
rebuttable presumption of no loss of wage-earning capacity arises when the claimant’s
post-injury wages are equal to or exceed his preinjury wage.” Gregg, 64 So. 3d at 476 (¶12).
The supreme court has held that a claimant can rebut this presumption bypresenting evidence
that
the post-injury earnings are unreliable due to: increase in general wage levels
since the time of accident, claimant’s own greater maturity and training, longer
hours worked by claimant after the accident, payment of wages
disproportionate to capacity out of sympathy to claimant, and the temporary
and unpredictable character of post-injury earnings.
Id. Additionally, “any factor or condition which causes the actual post-injury wages to
become a less reliable indicator of earning capacity will be considered, including the
claimant’s inability to work, continuing pain, and loss of access to the job market.” Kroger
Co. v. Pybus, 327 So. 3d 678, 684 (¶19) (Miss. Ct. App. 2021) (internal quotation mark
omitted).
¶58. The record reflects that after Dr. Calvert released Duren at MMI with no work
restrictions, Effex had work available for Duren and allowed him to return to his duties.
Duren did not dispute that upon returning to work, he continued to earn the same wages postinjury. Accordingly, a rebuttable presumption arose in this case that Duren suffered no loss
22
of wage-earning capacity. After our review, however, we find that Duren failed to show that
his post-injury wages were unreliable; therefore, he failed to overcome this presumption.
¶59. Duren returned to work at Effex on March 14, 2017, but he started feeling
“excruciating pain,” and he left work after a few hours. Duren returned to work the next day,
but he left early again when the pain returned. Duren did not show up to work on March 16,
2017, and Effex terminated his employment on March 17, 2017. Duren testified that he tried
to return to work at Effex, but he was in too much pain to perform his duties. Duren also
testified that he had applied for over one hundred jobs after he was fired, but he has not
received a job offer.
¶60. Although Duren failed to earn any wages after March 17, 2017, “he did not prove that
this loss of earnings resulted from his injury.” Mabus, 205 So. 3d at 685 (¶39); see also
Wagner, 825 So. 2d at 706 (¶10). As discussed, the AJ found that the medical evidence did
not support a finding of permanent impairment. We have held that an “incapacity to earn
wages and the extent thereof must be supported by medical findings, but the requirement is
met when the fact and extent of incapacity is corroborated in part by medical testimony.” Id.
(citation and internal quotation marks omitted) (quoting Greenwood Utils. v. Williams, 801
So. 2d 783, 791-92 (¶31) (Miss. Ct. App. 2001)). Accordingly, we find that Duren “could
not show how his post-injury wages were unreliable, or that his later loss of wages resulted
from his injury.” Mabus, 205 So. 3d at 686 (¶45).
¶61. The AJ ultimately determined that Duren failed to present persuasive medical
23
evidence that his work injury resulted in a permanent disability that caused him to suffer a
loss of wage-earning capacity. After our review, we find the Commission’s decision denying
permanent partial disability benefits was supported by substantial evidence.
II. Temporary Total Disability Benefits
¶62. Duren and the Employer/Carrier agree that Employer/Carrier paid Duren temporary
total disability benefits from July 14, 2016, the date of his injury, until March 10, 2017. Dr.
Calvert placed Duren at MMI on March 10, 2017. Duren argues that because Dr. Sloan
found that he did not actually reach MMI until February 20, 2020, the Commission erred by
failing to award Duren temporary total disability benefits from March 2017 until the present.
¶63. “Temporary disability, whether total or partial, has reference to the healing period
following injury[] until such time as the employee reaches the maximum benefit from
medical treatment.” Flowers v. Crown Cork & Seal USA Inc., 167 So. 3d 188, 191 (¶12)
(Miss. 2014). “Whether and when a claimant has reached maximum medical recovery are
questions which are to be determined by the Commission based on testimony from both lay
and medical witnesses.” Id. at (¶11); see also Chestnut v. Dairy Fresh Corp., 966 So. 2d
868, 871 (¶6) (Miss. Ct. App. 2007).
¶64. As the AJ acknowledged, the record shows that both Dr. Blount and Dr. Davis stated
that they either agreed with or deferred to Dr. Calvert’s finding of MMI. Only Dr. Sloan
disagreed with this finding, and he instead found that Duren reached MMI “as of” February
20, 2020, the same day that Dr. Sloan examined Duren.
24
¶65. As stated, “where there is conflicting medical testimony, the Commission has the
responsibility to apply its expertise and determine which evidence is more credible.”
Weathersby, 195 So. 3d at 882 (¶21). “We will uphold that determination unless it is clearly
erroneous.” Wesson v. Fred’s Inc., 811 So. 2d 464, 469 (¶23) (Miss. Ct. App. 2002). Here,
the AJ stated that he gave “little weight” to Dr. Sloan’s opinions because “they are far out
of line with Dr. Calvert, Dr. Blount and Dr. Davis” with regard to MMI and the impairment
ratings. Dr. Sloan’s report does not document a review of any records or findings from Dr.
Davis, nor did he document any review of Duren’s October 2018 MRI or CT scan.
¶66. After our review, we find that the Commission’s determination that Duren reached
MMI on March 10, 2017, was supported by substantial evidence.
III. Denial of Treatments, Medications, and Reimbursement for
Mileage at Mallory Health Center after Reaching MMI
¶67. Duren argues that the Commission erred in failing to hold the Employer/Carrier
responsible for his treatment, medications, and mileage at Mallory Health Center. Duren
claims that after he returned to work and suffered back and leg pain, Dr. Calvert refused to
treat him, and Duren had no choice but to seek treatment from Roberts at Mallory Health
Center. Duren further argues medications and treatments prescribed by Roberts were all
reasonable and medically necessary to treat Duren’s work injury.
¶68. The record reflects that on March 14, 2017, four days after Dr. Calvert placed Duren
at MMI and released him to work without restrictions, Duren went to Mallory Health Center
complaining of back and leg pain, as well as tingling and numbness in his left leg. Roberts
25
evaluated Duren and observed that he was walking stiffly and slowly with an abnormal gait.
Roberts prescribed him Gabapentin, a medication used to relieve nerve pain, and Mobic, an
anti-inflammatory medication used to relieve pain.
¶69. Duren returned to Mallory Health Center on April 19, 2017, again complaining of
back and leg pain, as well as weakness and left-leg numbness and tingling. The notes from
the appointment showed that Duren wanted to be referred to a specific pain management
doctor in Jackson, Mississippi. Roberts prescribed Duren Ketorolac Tromethamine, an
anti-inflammatory medication used to relieve pain, for his back pain, and she also increased
his dosage of Gabapentin. Roberts also referred Duren to a pain management clinic, and she
instructed him to follow-up with Dr. Calvert on his existing back issues to see if another
surgery was needed.
¶70. Duren followed up at Mallory Health Center on October 4, 2017. Roberts
recommended an x-ray of Duren’s spine. She also recommended that he undergo another
MRI of his cervical, thoracic, and lumbar spine without contrast. Roberts also prescribed
Hydrocodone Acetaminophen. Duren underwent an x-ray of his spine that same day, which
revealed mild facet arthropathy (arthritis).
A. Medications
¶71. In Dr. Blount’s April 27, 2018 report clarifying his IME findings, he agreed that
Roberts’s prescriptions for Gabapentin, Ketorolac Tromethamine, and Hydrocodone were
related to the treatment of Duren’s work injury. Dr. Blount also testified that it is reasonable
26
for a patient to go see a provider if he is still having pain after surgery. Dr. Blount stated
that, ideally, the patient would return to the treating physician, but often the patient returns
to his primary care physician or a nonsurgical provider for his postoperative pain. Dr. Blount
specifically agreed with Roberts’s use of the medication Gabapentin to treat Duren, stating
that it is his first choice for patients with lumbosacral radiculopathy, like Duren. Dr. Blount
recommended increasing Duren’s dosage of Gabapentin.
¶72. Dr. Calvert, however, opined that the medications Roberts prescribed Duren were not
reasonable or necessary. Dr. Calvert explained that Gabapentin is a pain medication meant
to modulate the nerve, and Duren complained of back pain, so Gabapentin would not be
indicated and therefore would not be a medically reasonable treatment. Dr. Calvert stated
that when he released Duren on March 10, 2017, he did not need these medications because
his leg pain was gone. Dr. Calvert testified that if Duren’s back pain and leg pain was
significant enough for him to seek medical treatment four days after being released at MMI,
Mobic would be a reasonable and necessary medication to treat Duren, but only for the
limited time period of a month or less.
¶73. In response to Duren’s claimthat Dr. Calvert refused to treat him after Duren returned
to work, Dr. Calvert testified that he was not aware that Duren had contacted him. Dr.
Calvert explained that he will typically see a patient if the patient experiences problems after
being released from treatment. During the deposition, counsel for the Employer/Carrier
informed Dr. Calvert that the AJ ordered the Employer/Carrier to contact Dr. Calvert’s office
27
and ask him to see Duren for a follow-up visit, and counsel was told that Dr. Calvert was not
willing to see Duren and had nothing further to offer. Dr. Calvert testified that as far as he
could recall, Duren never contacted him, and Dr. Calvert did not recall “closing the door” on
follow-up treatments for Duren “other than saying he’s at [MMI].” Dr. Calvert stated that
it had been too long for him to remember if he closed the door on treating Duren or if
“workers’ compensation” closed the door on further treatment. Dr. Calvert also testified that
when he closes a workers’ compensation case and places someone at MMI, then “the case
is closed” from a workers’ compensation perspective, and he is unwilling to see a patient
back for complaints that they think stem for the previous workers’ compensation claim. Dr.
Calvert explained that “sometimes it can be difficult because I have to protect my clinic from
[workers’ compensation] patients who are trying to take advantage of the system and
continuing wanting to get follow-up and follow-up, and which can make it very difficult for
me to see patients and continue to provide care for the rest of the community.” Dr. Calvert
testified that he had concerns that Duren was “malingering,” explaining that Duren made it
clear that he did not want to return to work and that he “catastrophicized” the pain.
B. Pain Management and Physical Therapy
¶74. Duren also argues that the Commission erred in denying Duren reasonable medical
treatments, pain management, physical medicine, and physical therapy as recommended by
his doctors, including Dr. Blount, Dr. Davis, and Dr. Calvert.
¶75. On April 8, 2021, after filing his notice of appeal fromthe Commission’s order, Duren
28
filed a letter with the Full Commission in which he requested several corrections to the
record. Duren also asserted as follows:
Dr. [Calvert] agreed to look over [the] last MRI done on October 25, 2018 and
make a determination [as to] whether I should continue with medical
treatments due to my work injuries. He clearly states he recommended I, J. W.
Duren, continued pain management and/or physical medicine and rehab
recommendations. I don’t see where [the Employer/Carrier] have given me
any of these treatment after or before December 7, 2018, [(the date of Dr.
Calvert’s report issuing this finding)]. I have been denied medical treatments
per treating Dr. Calvert for [four] years.
The Full Commission entered an order on June 15, 2021, finding that “[t]his appears to be
an argument for the appellate court to consider rather than any objection to the content of the
record. The argument has to do with treatment allegedly recommended by Dr. Calvert and
not approved by Employer and Carrier.”
¶76. The record reflects that Duren filed several motions to compel medical treatment and
specifically requested that the AJ “enter an [o]rder instructing the Employer and Carrier to
approve and pay for [Duren’s] referral to pain management treatment.” The AJ entered an
order denying the motions, with the most recent order being the March 20, 2019 order. In
that order, the AJ denied Duren’s third renewed motion to compel medical treatment after
finding that the treatments prescribed by Mallory Health Center were not reasonable and
necessary. The AJ’s September 2, 2020 final order, which the Commission affirmed and
adopted, stated that Duren “is entitled to continuing medical treatment under the Act as long
as it is reasonable, necessary and related to the claimant’s work injury[.]” The AJ
specifically incorporated his March 20, 2019 order into the final order.
29
¶77. Turning to review the medical evidence regarding Duren’s pain management referral,
the record reflects that Dr. Davis testified that he did not recommend a referral to pain
management. Dr. Davis testified that after looking at the imaging from Duren’s MRI, he saw
that the pathology had been successfully addressed. Dr. Davis explained that subjective pain
is pain that cannot be corroborated. Dr. Davis testified that the MRI scan and CT scans
showed no evidence of any structural abnormalitythat was consistent with or fit with Duren’s
ongoing subjective complaints of pain.
¶78. When asked whether he agreed with the nurse practitioner’s referral to pain
management, Dr. Blount responded that “[c]hronic pain related to a postsurgical Workers’
Compensation case should be managed by a medical professional trained and familiar with
the process. I would agree to transfer from [the] nurse practitioner to [a] higher level of care.
Services rendered, however, would need to be reviewed prior to my opinion.” During his
deposition, Dr. Blount clarified that if pain is still a problem for Duren, “it is possible that
some degree of self-management, some degree of pain management, and possibly a position
with work limitations or restriction, could get Mr. Duren back in the workplace” without the
use of Ultram or opiods.
¶79. Dr. Calvert disagreed with Dr. Blount’s opinion that Duren could benefit from being
evaluated by a pain management specialist, explaining, “Dr. Blount says that [Duren] has
axial related pain and only intermittent leg symptoms, and Dr. Blount even said that [Duren]
does not qualify for axial injections, so I really don’t understand what the point of the pain
30
management physician is in this particular case.” However, Dr. Calvert issued an updated
report on December 7, 2018, after reviewing Duren’s October 25, 2018 MRI results. Dr.
Calvert found that the new MRI “does not shed any light or explanations” for Duren’s
continued complaints of pain, and “[f]or this reason[,] Isee no reason to evaluate Mr. Duren
for revision surgery or changes in treatment.” Dr. Calvert then stated that he recommended
“continued pain management, and/or physical medicine and rehab recommendations.”
C. Reimbursement
¶80. In his final order, the AJ found, after reviewing the medical evidence, that “[n]othing
submitted at the merit hearing changed this [AJ’s] opinion” regarding the treatments or
medications prescribed by Mallory Health Center after Duren reached MMI on March 10,
2017. The AJ reiterated his findings from his March 20, 2019 order where he found that the
medications and treatment provided by Mallory Health Center were not reasonable and
necessary and were therefore not the responsibility of the Employer/Carrier. The AJ
incorporated this prior order into his final judgment. The AJ also stated that based on these
findings, theEmployer/Carrierwere notresponsible for anymileage reimbursement for travel
to Mallory Health Center or to pick up medications prescribed by Mallory Health Center.
The record shows that the AJ considered Dr. Calvert’s December 7, 2018 report in his March
20, 2019 order as well as in his September 2, 2020 final order ruling on the merits of Duren’s
compensation claim.
¶81. After our review, we find that the Commission’s decision was supported by
31
substantial evidence in the record and was not clearly erroneous.
¶82. We find that while the Commission did deny Duren’s requests for pain management
and payment of the medications prescribed by Roberts as not a reasonable or necessary
medical treatment, the Commission did not make any findings regarding physical therapy.
However, we do not see in the record where, or if, Duren requested payment for physical
therapy or a referral to physical therapy. Roberts did not recommend physical therapy as a
treatment for Duren, nor did Roberts refer Duren to a physical therapist.
IV. Additional Claims of Error
¶83. Finally, Duren claims that the AJ failed to enter and weigh all the evidence submitted
by Duren, Dr. Blount, and Roberts, including Dr. Sloan’s February 20, 2020 IME report and
addendum, the physical therapy report from Tyler Holmes Rehab, Duren’s CT scan from
January 8, 2019, and his MRI from October 25, 2018.
¶84. The record on appeal before us contains the medical records from Roberts at Mallory
Health Clinic; the IME report and deposition of Dr. Blount; Dr. Sloan’s IME report and
addendum; as well as reports from Dr. Davis and Dr. Calvert stating the results from Duren’s
CT scan and MRI. As stated above, the AJ had the responsibility to determine which of the
conflicting medical evidence was more credible, and we find that the AJ’s determinations,
and thus the Commission’s, were supported by substantial credible evidence.
¶85. The record does not, however, contain any report from Tyler Holmes Rehab or
Duren’s actual CT scan and MRI. Duren, as the claimant, bears the burden of proving that
32
his work injury resulted in a permanent disability causing him to suffer a loss of wageearning capacity, and this disability must be supported by medical findings. Duren had the
opportunity to submit his physical therapy report and the actual CT scan and MRI at the
evidentiary hearing before the AJ, and the record reflects that he did not submit these
documents. “[T]his Court only considers the medical evidence properly admitted before the
AJ and Commission.” Mabus, 205 So. 3d at 683 (¶28). Therefore, we decline to further
address this claim.

Outcome: After our review, we find that the Commission’s decision that Duren failed to prove
that he suffered a permanent disability is supported by substantial evidence. Therefore, we affirm the Commission’s denial of permanent partial disability benefits. For the reasons set forth above, we also affirm the Commission’s decision awarding temporary total disability benefits until March 10, 2017, the date of MMI, and denying medical treatments or prescriptions recommended by Roberts, as well as mileage reimbursement, after Duren reached MMI.
