DECISION AND ORDER

Before:

JANICE B. ASKIN, Judge

PATRICIA H. FITZGERALD, Alternate Judge

VALERIE D. EVANS-HARRELL, Alternate Judge

JURISDICTION

On October 31, 2019 appellant filed a timely appeal from August 1 and 20, 2019 merit 

decisions of the Office of Workers’ Compensation Programs (OWCP). Pursuant to the Federal 

Employees’ Compensation Act1(FECA) and 20 C.F.R. §§ 501.2(c) and 501.3, the Board has 

jurisdiction over the merits of this case.

ISSUES

The issues are: (1) whether appellant has met her burden of proof to establish a recurrence 

of total disability, commencing October 24, 2018, causally related to her accepted employment 

injury; and (2) whether appellant has met her burden of proof to establish disability on June 8 

and 9, 2019 causally related to her accepted employment injury.

FACTUAL HISTORY

On November 18, 2014 appellant, then a 54-year-old clerk, filed an occupational disease 

claim (Form CA-2) alleging that she experienced left knee pain due to her repetitive federal 

employment duties. OWCP accepted the claim for left knee sprain, left knee meniscal tear, and 

bilateral knee primary osteoarthritis. It paid appellant wage-loss compensation on the 

supplemental rolls and subsequently on the periodic rolls. 

Appellant returned to part-time limited-duty work on October 22, 2016 for four hours per 

day. She returned to full-time full-duty work on February 20, 2017. On October 25, 2018 

appellant accepted the employing establishment’s offer of a part-time modified assignment as a 

parcel post distribution machine clerk scanning small parcel bundles/hanging sacks.

Appellant subsequently filed claims for compensation (Form CA-7) for intermittent 

periods of disability for the period October 24, 2018 through January 18, 2019. On time analysis 

forms (Form CA-7a) dated November 19 and 28, December 11 and 24, 2018, and January 7 

and 22, 2019 she claimed eight hours of leave without pay (LWOP) used on October 24, 2018 and 

four hours of LWOP for each day thereafter because no work was available. On the reverse side 

of the Form CA-7, the employing establishment controverted appellant’s claim, contending that 

she had not submitted documentation establishing that no work was available. It noted that she

returned to work on October 25, 2018 based on an October 24, 2018 medical report. 

In support of her claims, appellant submitted medical reports from Dr. Besimah Khulusi, 

an attending Board-certified physiatrist. In duty status reports (Form CA-17) and progress reports

dated October 24 and 26, 2018, Dr. Khulusi diagnosed right knee degenerative joint disease (DJD)

and acceleration of DJD of the left knee. She also diagnosed the accepted conditions of left knee 

medial meniscus tear and left knee sprain, and status post left knee total knee replacement 

performed on June 20, 2016. Dr. Khulusi noted that appellant could not perform her regular work, 

but she could work with restrictions, four hours per day. In the November 26, 2018 progress 

report, she advised that appellant’s employment duties had caused a worsening of her accepted 

right knee osteoarthritis, which required additional work restrictions and a need for total right knee 

replacement.

An October 30, 2018 progress note by Dr. Paul K. Gilbert, a Board-certified orthopedic 

surgeon, provided examination findings. He diagnosed right knee unilateral primary osteoarthritis, 

status post total left knee replacement, and right knee pain. 

A left knee x-ray was performed on October 30, 2018 by Dr. Jordan Gross, a Boardcertified radiologist, provided impressions of stable left total knee arthroplasty, without evidence 

of interval complication, and tricompartmental osteoarthrosis of the right knee, most advanced at 

the medial tibiofemoral compartment. In a bilateral pelvis x-ray report of even date, Dr. Gross 

provided an impression of no significant osteoarthrosis of either hip. 

By decision dated January 28, 2019, OWCP denied appellant’s claim for a recurrence of 

total disability commencing October 24, 2018. It found that the medical evidence of record was 

insufficient to establish that she was disabled from work due to a material change/worsening of 

her accepted employment-related conditions.
3

OWCP received an additional Form CA-17 report and federal physician’s progress report 

dated February 5, 2019 by Dr. Khulusi, who restated his diagnosis of right knee DJD and opinion 

that, while appellant could not perform her regular work, she could work with restrictions.

In an additional report dated October 30, 2018, Dr. Gross noted that a bilateral knee x-ray 

revealed stable left total knee arthroplasty, without evidence of interval complication, and 

tricompartmental osteoarthrosis of the right knee, most advanced at the medial tibiofemoral 

compartment.

Dr. Gilbert, in additional progress notes dated April 5, 2019, reiterated his prior diagnoses 

of right knee unilateral primary osteoarthritis, status post total left knee replacement, and right 

knee pain. He also diagnosed a failure of conservative care and limitation of activity. Dr. Gilbert 

noted that a right total knee arthroplasty was planned.2

On May 22, 2019 appellant requested reconsideration of the January 28, 2019 decision. In 

support of her request, she submitted a May 22, 2019 letter from Dr. Khulusi. Dr. Khulusi noted 

that appellant’s surgeon, Dr. Gilbert, allowed her to return to work without restrictions upon 

healing from her left knee replacement. She further noted that a prior impartial medical examiner 

of record, Dr. Stephen Wertheimer, a Board-certified orthopedic surgeon, advised OWCP that 

appellant would require significant modification of her job activities until both of her knees were 

replaced and thereafter the osteoarthritis in her knee would continue to deteriorate in the future, 

which occurred. Dr. Khulusi maintained that FECA provides that additional exposure to the same 

work factors, when the diagnosis remains the same and disability increases, constituted a 

recurrence of the condition.

In a May 8, 2019 Form CA-17 report, Dr. Khulusi continued to diagnose right knee DJD 

and note appellant’s work restrictions. 

Dr. Khulusi, in a Form CA-20 report dated May 22, 2019, diagnosed “M170, 8449, and 

8360.” She checked a box marked “Yes” to indicate that appellant’s conditions were caused or 

aggravated by her federal employment. Dr. Khulusi noted that she was totally disabled from 

June 10 through October 25, 2019.

A February 11, 2019 right knee magnetic resonance imaging scan performed by Dr. Eric 

Chen, a diagnostic radiologist, provided impressions of diffuse tearing of the medial meniscus 

anterior horn and body with a very macerated appearance, advanced knee osteoarthrosis, mild 

marrow edema at the inferior aspect of the patella, moderate-size joint effusion, and small Baker’s 

cyst.

In a May 28, 2019 bilateral knee x-ray report, Dr. Dakshesh Patel, a Board-certified 

diagnostic radiologist, noted impressions of right knee osteoarthrosis with severe medial 

compartment joint space narrowing and grossly uncomplicated appearing left total knee 

arthroplasty, unchanged from prior study.

 

2 OWCP authorized the proposed right knee total replacement based on the opinion of its district medical adviser. 
4

On June 10, 2019 appellant filed a Form CA-7 claim for compensation for disability from

June 10 through October 25, 2019.

In support of her claim, appellant submitted a May 28, 2019 adult ambulatory patient 

history report from Marisela Ponce.

3

Dr. Gilbert, in a June 10, 2019 report, performed a presurgical physical examination and 

reiterated his prior right and left knee diagnoses. In a June 10, 2019 operative report, Dr. Gilbert 

described the procedure for right total knee arthroplasty with computer navigation. He noted 

preoperative and postoperative diagnoses of unilateral, primary osteoarthritis of the right knee.

On June 24, 2019 appellant filed a Form CA-7 claiming disability from work from June 8 

through 21, 2019. In a Form CA-7a of even date, she claimed four hours of LWOP used on June 8 

and 9, 2019. Appellant also claimed eight hours of LWOP used from June 12 through 21, 2019

because she was totally disabled from work.

4

In support of her claim, appellant submitted a June 11, 2019 report from Dr. Bryce Turner, 

a Board-certified internist. Dr. Turner noted that appellant was one day status post right total knee 

replacement. He discussed physical examination and findings and laboratory test results. 

Dr. Turner provided impressions of past medical history of hypertension and osteoarthritis a status 

post right total knee replacement.

In a June 11, 2019 consult note, Dr. Farid Nikbin, an anesthesiologist, evaluated appellant 

and noted her pain medication. 

OWCP, in a development letter dated July 1, 2019, requested that appellant submit medical 

evidence to establish that she was temporarily totally disabled on June 8 and 9, 2019. It afforded 

her 30 days to submit the necessary evidence. 

In a May 28, 2019 report, Dr. Michael Karp, a Board-certified internist, discussed 

examination findings and provided an assessment of appellant’s preoperative cardiovascular 

condition for knee replacement for severe osteoarthritis. He also provided an assessment of wellcontrolled hypertension. 

On June 10, 2019 Dr. Cindy Xiao Res, an anesthesiologist, reported examination findings 

and laboratory test results. She noted assessments of right knee pain, status post total left knee 

replacement, and right knee unilateral primary osteoarthritis.

In a June 10, 2019 right knee x-ray, Dr. George Matcuk, a diagnostic radiologist, noted an 

impression of limited postoperative study demonstrating interval placement of a right total knee 

arthroplasty without gross evidence of complication or retained surgical instrument. 

 

3 Ms. Ponce’s professional qualifications are not contained in the case record.

4 OWCP paid appellant wage-loss compensation on the periodic rolls for the period June 10 through July 20, 2019. 
5

Dr. Gilbert, in a June 25, 2019 report, noted findings on physical examination. He reported 

that appellant was status post right total knee arthroplasty. Dr. Gilbert addressed her medication. 

A June 25, 2019 report signed by a physician assistant provided a diagnosis of status post 

right total knee replacement and ordered physical therapy.

By decision dated August 1, 2019, OWCP denied appellant’s claim for compensation for 

June 8 and 9, 2019, finding that she had not submitted a rationalized medical opinion sufficient to 

establish that she was totally disabled on the claimed dates.

In a July 24, 2019 report, Dr. Gilbert evaluated appellant and again provided an assessment 

of status post total right knee replacement.

Dr. Khulusi, in an August 12, 2019 Form CA-17 report, advised that appellant was 

temporarily totally disabled from work. 

By decision dated August 20, 2019, OWCP denied modification of its January 28, 2019 

decision.

LEGAL PRECEDENT -- ISSUE 1

A recurrence of disability means an inability to work after an employee has returned to 

work, caused by a spontaneous change in a medical condition which resulted from a previous 

compensable injury or illness and without an intervening injury or new exposure in the work 

environment.5 This term also means an inability to work because a light-duty assignment made 

specifically to accommodate an employee’s physical limitations and, which is necessary because 

of a work-related injury or illness, is withdrawn or altered so that the assignment exceeds the 

employee’s physical limitations. A recurrence does not occur when such withdrawal occurs for 

reasons of misconduct, nonperformance of job duties, or a reduction-in-force.6

OWCP’s procedures provide that a recurrence of disability includes a work stoppage 

caused by a spontaneous material change in the medical condition demonstrated by objective 

findings. That change must result from a previous injury or occupational illness rather than an 

intervening injury or new exposure to factors causing the original illness. It does not include a 

condition that results from a new injury, even if it involves the same part of the body previously 

injured.7

When an employee who is disabled from the job he or she held when injured on account 

of employment-related residuals returns to a limited-duty position or the medical evidence of 

record establishes that he or she can perform the limited-duty position, the employee has the burden 

of proof to establish by the weight of the reliable, probative, and substantial evidence a recurrence

of total disability and to show that he or she cannot perform such limited-duty work.8 As part of 

this burden, the employee must show a change in the nature and extent of the injury-related 

condition, or a change in the nature and extent of the limited-duty job requirements.9

An employee who claims a recurrence of disability due to an accepted employment-related 

injury has the burden of proof to establish by the weight of the substantial, reliable, and probative 

evidence that the disability for which he or she claims compensation is causally related to the 

accepted injury. This burden of proof requires that a claimant furnish medical evidence from a 

physician who, on the basis of a complete and accurate factual and medical history, concludes that, 

for each period of disability claimed, the disabling condition is causally related to the employment 

injury, and supports that conclusion with medical reasoning.10 Where no such rationale is present, 

the medical evidence is of diminished probative value.11

ANALYSIS -- ISSUE 1

The Board finds that appellant has not met her burden of proof to establish a recurrence of 

total disability commencing October 24, 2018 causally related to her accepted employment injury. 

Appellant claimed that she sustained a recurrence of disability commencing October 24, 

2018 because the employing establishment had no work available within her work restrictions. 

She did not submit any evidence to support this allegation and the employing establishment refuted 

her contention. The employing establishment maintained that appellant had not submitted 

evidence to establish that no work was available on October 24, 2018. It indicated that she 

performed part-time limited-duty work. The Board notes that the employing establishment’s parttime limited-duty job offer was based on the October 24, 2018 Form CA-17 report of appellant’s

own physician, Dr. Khulusi, who opined that, while appellant could not perform her regular work, 

she could perform part-time work with restrictions. As appellant has provided no independent 

evidence to support her allegation, the Board finds that the limited-duty position was available 

commencing October 24, 2018.

12

The Board further finds that the remaining medical evidence submitted by appellant is also 

insufficient to establish a worsening of her work-related conditions resulting in her disability 

commencing October 24 2018. Appellant submitted a series of reports from Dr. Khulusi. In a 

progress report dated November 26, 2018, Dr. Khulusi opined that appellant’s employment duties 

worsened her accepted right knee osteoarthritis and required additional work restrictions and need 

for right total knee replacement. She advised that she could return to modified work with 

restrictions. Dr. Khulusi reiterated her opinion on causal relationship in a May 22, 2019 report.

Although she suggested that appellant’s worsening condition and continuing disability were due 

to her federal employment, she did not provide medical rationale explaining how her work duties 

worsened her accepted left knee condition and resulted in her disability from work during the 

claimed period. The Board has held that the fact that a condition manifests itself or worsens during 

a period of employment or that work activities produce symptoms revelatory of an underlying 

condition does not raise an inference of causal relationship between a claimed condition/period of 

disability and employment factors.13 Additionally, the Board has held that a report is of limited 

probative value regarding causal relationship if it does not contain adequate medical rationale 

explaining the relationship between a given condition/period of disability and the claimant’s 

employment.14 Therefore, Dr. Khulusi’s reports are insufficient to establish appellant’s recurrence 

claim.

In a May 22, 2019 Form CA-20, Dr. Khulusi diagnosed “M170, 8449, and 8360.” She 

checked a box marked “Yes” indicating that appellant’s conditions were caused or aggravated by 

her employment injury. Dr. Khulusi also opined that she was totally disabled from work from 

June 10 through October 25, 2019. The Board has held that to establish a period of disability the 

medical evidence must provide a discussion of how objective medical findings, attributable to the 

accepted conditions, support a finding that a claimant could not perform his or her job duties.15 As 

such, this report is insufficient to discharge appellant’s burden of proof with respect to her 

recurrence of disability claim. 

Dr. Khulusi’s August 12, 2019 Form CA-17 report found that appellant was totally disabled 

from work. However, she did offer an opinion on whether the accepted employment injury caused

disability from employment due to a worsening of the work-related conditions consequently. The 

Board has held that medical evidence that does not provide an opinion as to whether a period of 

disability is due to an accepted employment-related condition is insufficient to meet a claimant’s 

burden of proof.16 The Board will not require OWCP to pay compensation for disability in the 

absence of medical evidence directly addressing the specific dates of disability for which 

compensation is claimed. To do so, would essentially allow an employee to self-certify their 

disability and entitlement to compensation.17 Thus, Dr. Khulusi’s report is insufficient to establish 

appellant’s recurrence claim.

Dr. Khulusi’s remaining Form CA-17 reports, including her October 24, 2018 Form CA-17 

report, diagnosed right knee DJD and found that appellant could work part time with restrictions 

for hours per day. However, she did not address whether the accepted right knee DJD worsened

spontaneously, such that appellant was disabled from performing her limited-duty position. In the

absence of such an opinion, Dr. Khulusi’s reports are of no probative value and thus insufficient 

to meet appellant’s burden of proof.18

Similarly, the reports of Drs. Gilbert, Turner, Nikbin, Karp, and Res, which addressed 

appellant’s right knee condition of unilateral primary osteoarthritis, authorized bilateral total knee 

replacement arthroplasties, and pain treatment, are of no probative value as none of these 

physicians provided an opinion regarding whether appellant was totally disabled from work during 

the claimed period due to the accepted employment injury.19

The October 30, 2018 and February 11, May 28, and June 10, 2019 diagnostic test results 

of Drs. Gross, Chen, Patel, and Matcuk addressed appellant’s bilateral knee and bilateral pelvis, 

conditions. However, the Board has held that reports of diagnostic tests, standing alone, lack 

probative value as they fail to provide an opinion on the causal relationship between his 

employment duties and the diagnosed conditions.20

The June 25, 2019 report signed by a physician assistant diagnosed status post right total 

knee replacement and ordered physical therapy. However, the Board has held that physician 

assistants are not considered physicians as defined under FECA, and thus, the report is of no 

probative value.21

Appellant also submitted the May 28, 2019 report by Ms. Ponce whose professional 

qualifications are not contained in the case record. The Board has held that a medical report may 

not be considered probative medical evidence if there is no indication that the person completing 

the report qualifies as a physician under FECA.22 Therefore, this report is insufficient to establish 

the claim.

As appellant has not submitted medical evidence establishing a recurrence of total 

disability commencing October 24, 2018, causally related to her accepted employment injury, the 

Board finds that she has not met her burden of proof.

LEGAL PRECEDENT -- ISSUE 2

For each period of disability claimed, the employee has the burden of proof to establish

that he or she was disabled from work as a result of the accepted employment injury.23 Whether a

particular injury causes an employee to become disabled from work, and the duration of that

disability, are medical issues that must be proven by a preponderance of probative and reliable

medical opinion evidence.24

Under FECA, the term disability means an incapacity because of an employment injury, to

earn the wages the employee was receiving at the time of the injury.25 When, however, the medical

evidence establishes that the residuals or sequelae of an employment injury are such that, from a

medical standpoint, prevent the employee from continuing in his or her employment, he or she is

entitled to compensation for any loss of wages.26

To establish causal relationship between the disability claimed and the employment injury,

an employee must submit rationalized medical evidence, based on a complete factual and medical

background, supporting such causal relationship.27 The opinion of the physician must be one of

reasonable medical certainty and must be supported by medical rationale explaining the nature of

the relationship between the diagnosed condition and the specific employment factors identified

by the employee.28

ANALYSIS -- ISSUE 2

The Board finds that appellant has not met her burden of proof to establish disability on 

June 8 and 9, 2019 causally related to her accepted employment injury.

For the claimed wage loss on June 8 and 9, 2019, the Board finds that the record is devoid 

of medical evidence supporting that appellant was disabled due to the accepted employment 

injury.

 The Board will not require OWCP to pay compensation for disability in the absence of 

medical evidence directly addressing the specific dates of disability for which compensation is

claimed. To do so would essentially allow employees to self-certify their disability and entitlement 

to compensation.30

As there is no medical evidence of record establishing employment-related disability on 

June 8 and 9, 2019, appellant has failed to meet her burden of proof.

Appellant may submit new evidence or argument with a written request for reconsideration 

to OWCP within one year of this merit decision, pursuant to 5 U.S.C. § 8128(a) and 20 C.F.R. 

§§ 10.605 through 10.607.

CONCLUSION

The Board finds that appellant has not met her burden of proof to establish a recurrence of 

total disability, commencing October 24, 2018, causally related to her accepted employment 

injury. The Board further finds that appellant has not met her burden of proof to establish disability 

on June 8 and 9, 2019 causally related to her accepted employment injury.
