JURISDICTION

On February 28, 2023 appellant, through counsel, filed a timely appeal from a 

September 30, 2022 merit decision and a February 9, 2023 nonmerit decision of the Office of 

Workers’ Compensation Programs (OWCP). Pursuant to the Federal Employees’ Compensation 

Act2(FECA) and 20 C.F.R. §§ 501.2(c) and 501.3, the Board has jurisdiction over the merits of 

this case.

or other service performed on appeal before the Board is valid unless approved by the Board. 20 C.F.R. § 501.9(e). 

No contract for a stipulated fee or on a contingent fee basis will be approved by the Board. Id. An attorney or 

representative’s collection of a fee without the Board’s approval may constitute a misdemeanor, subject to fine or 

imprisonment for up to one year or both. Id.; see also 18 U.S.C. § 292. Demands for payment of fees to a

ISSUES

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

knee condition causally related to the accepted factors of her federal employment; and (2) whether 

OWCP properly denied appellant’s request for reconsideration of the merits of her claim, pursuant 

to 5 U.S.C. § 8128(a).

FACTUAL HISTORY

This case has previously been before the Board.3 The facts and circumstances as set forth 

in the Board’s prior decisions are incorporated herein by reference. The relevant facts are as 

follows.

On May 15, 2014 appellant, then a 54-year-old letter carrier, filed an occupational disease 

claim (Form CA-2) alleging that she sustained a bilateral knee condition due to factors of her 

federal employment, including standing and walkingfor prolonged periods of time. She noted that 

she first became aware of her condition and its relationship to her federal employment on 

April 29, 2014. Appellant stopped work on April 29, 2014 and returned to work in a modifiedduty capacity on May 10, 2014.

By decision dated August 8, 2014, OWCP denied appellant’s claim, finding that the 

medical evidence of record was insufficient to establish that her diagnosed bilateral knee condition

was causally related to the accepted factors of her employment.

On September 4, 2014 appellant requested an oral hearing before a representative of

OWCP’s Branch of Hearings and Review. A hearing was held on February 9, 2015.

By decision dated March 18, 2015, OWCP’s hearing representative affirmed the August 8, 

2014 decision, finding that the evidence of record was insufficient to establish that appellant’s 

bilateral knee osteoarthritis was causally related to the accepted factors of her federal employment. 

On June 9, 2015 and August 15, 2016 appellant requested reconsideration. By decisions

dated September 2, 2015 and December 26, 2017, OWCP denied modification. 

On April 23, 2018 appellant, through counsel, appealed to the Board. By decision dated 

April 5, 2019,4the Board affirmed the December 26, 2017 decision, finding that the medical 

evidence of record was insufficient to establish a bilateral knee condition causally related to the 

accepted factors of federal employment.

On April 13, 2020 appellant requested reconsideration. By decision dated June 24, 2020, 

OWCP denied modification.

OWCP thereafter received a report from Dr. Allen Fein, a Board-certified specialist in 

family medicine. Dr. Fein related that he was familiar with appellant’s employment duties, which

required that she spend several hours a day on her feet, mostly on concrete surfaces. Once out on 

her route, she would make stops throughout the day, bending her knees to enter and exit her 

vehicle. Dr. Fein also noted that she was required to climb up and down stairs. He concluded that,

over time, appellant’s knee cartilage became increasing worn, and as less cartilage could cushion 

the bone, she experienced more wear and tear on the joint. Dr. Fein noted that her x-rays reflected

her thinning cartilage and smaller than usual joint spaces.

On August 11, 2020 appellant, through counsel, appealed to the Board. By decision dated 

August 3, 2021,

5

the Board set aside the June 24, 2020 decision and remanded the case for further 

development of the medical evidence. The Board found that the February 20, 2020 report from

Dr. Fein, provided a physiological explanation as to how appellant’s work activities caused her 

diagnosed condition, which warranted further development of the medical record, to be followed 

by the issuance of a de novo decision. 

On February 18, 2022 OWCP referred appellant for a second opinion evaluation with

Dr. Teresa Habacker, a Board-certified orthopedic surgeon. It asked Dr. Habacker to address 

whether there was a causal relationship between appellant’s diagnosed conditionsand the accepted 

factors of federal employment. OWCP also asked her to provide treatment recommendations and 

work restrictions. In a report dated March 31, 2022, Dr. Habacker noted appellant’s history of 

injury and medical treatment. She listed physical examination findings, reviewed medical records, 

and diagnosed aggravated bilateral knee arthritis. Dr. Habacker opined that on April 29, 2014

appellant jumped from her mail truck and injured her right knee. She indicated that this incident

caused a temporary aggravation of the diagnosed condition as there was no evidence of a 

permanent aggravation. Dr. Habacker found that appellant’s current condition was unrelated to 

the April 29, 2014 accident. She recommended a sedentary job based on appellant’s obesity and 

severe bilateral knee osteoarthritis. 

On August 8, 2022 OWCP requested clarification from Dr. Habacker regarding whether 

appellant sustained a traumatic injury on April 29, 2014 or an occupational disease due to 

repetitive factors of employment over more than a day.

In a supplemental report dated September 9, 2022, Dr. Habacker reviewed the additional 

documents provided by OWCP. She opined that appellant had an occupational knee condition due 

to repetitive stress, which was complicated by obesity. Additionally, Dr. Habacker found no 

evidence supporting a traumatic injury on April 29, 2014. She diagnosed aggravated bilateral knee 

arthritis, which she attributed to appellant’s employment. In support of this conclusion,

Dr. Habacker explained that osteoarthritis occurs either traumatically or over time with excessive 

wear and tear. However, she indicated that she was unable to determine that the diagnosed 

osteoarthritis was due to appellant’s employment, but noted that “it may be an impinging factor.”

By decision dated September 30, 2022, OWCP denied appellant’s claim, finding that

Dr. Habacker’s opinion represented the weight of the medical evidence.

On November 21, 2022 appellant, through counsel, requested reconsideration. Counsel 

asserted thatDr. Habacker, in her supplemental September 9, 2022 report, was clear in her opinion 

5 Docket No. 20-1503 (issued August 3, 2021).

that appellant’s osteoarthritic knee condition was occupational and due to repetitive stress. Thus, 

he asserted Dr. Habacker’s opinion established that appellant’s arthritic condition was at least 

aggravated by employment factors and that the claim should be accepted for aggravation of 

bilateral knee osteoarthritis.

By decision dated February 9, 2023, OWCP denied reconsideration of the merits of the 

claim, pursuant to 5 U.S.C. § 8128(a). 

LEGAL PRECEDENT -- ISSUE 1

An employee seeking benefits under FECA6 has the burden of proof to establish the 

essential elements of his or her claim, including that the individual is an employee of the United 

States within the meaning of FECA, that the claim was filed within the applicable time limitation 

period of FECA,

7

that an injury was sustained while in the performance of duty as alleged, and 

that any disability or specific condition for which compensation is claimed is causally related to 

the employment injury.

8

 These are the essential elements of each and every compensation claim, 

regardless of whether the claim is predicated upon a traumatic injury or an occupational disease .

9

In an occupational disease claim, appellant’s burden of proof requires submission of the 

following: (1) a factual statement identifying employment factors alleged to have caused or 

contributed to the presence or occurrence of the disease or condition; (2) medical evidence 

establishing the presence or existence of the disease or condition for which compensation is 

claimed; and (3) medical evidence establishing that the diagnosed condition is causally related to 

the employment factors identified by the employee.

10

Causal relationship is a medical issue that requires rationalized medical opinion evidence 

to resolve the issue.

11

 The opinion of the physician must be based on a complete factual and 

medical background of the claimant, 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.

12

In any case where a preexisting condition involving the same part of the body is present 

and the issue of causal relationship therefore involves aggravation, acceleration, or precipitation, 

the physician must provide a rationalized medical opinion that differentiates between the effects 

of the work-related injury or disease and the preexisting condition.13

ANALYSIS -- ISSUE 1

The Board finds that the case is not in posture for decision.

OWCP referred appellant to second opinion physician, Dr. Habacker. In a report dated 

March 31, 2022, Dr. Habacker diagnosed aggravated bilateral knee osteoarthritis. She opined that 

the April 29, 2014 incident temporarily aggravated appellant’s bilateral knee osteoarthritis and that 

her current condition was unrelated to the accepted employment injury. Dr. Habacker, in a

September 9, 2022 supplemental report opined that appellant’s employment aggravated her 

bilateral knee arthritis. She opined that appellant had an occupational knee condition due to 

repetitive stress, which was complicated by obesity. However, Dr. Habacker also indicated that 

she was unable to determine whether the diagnosed bilateral knee osteoarthritis was due to 

appellant’s employment. As her opinion is contradictory, OWCP was required to seek further 

clarification from Dr. Habacker.

It is well established that proceedings under FECA are not adversarial in nature, and while 

appellant has the burden of proof to establish entitlement to compensation, OWCP shares 

responsibility in the development of the evidence.14 It has an obligation to see that justice is done.15 

As it undertook development of the evidence by referring appellant to Dr. Habacker, it had the 

duty to secure an appropriate report based on an accurate factual and medical background and 

which is internally consistent.

16

 

Accordingly, this case will be remanded to OWCP for further development of the medical 

evidence. On remand OWCP shall request that Dr. Habacker clarify her opinion as to whether the

accepted work factors contributed to appellant’s diagnosed conditions. Alternatively, if she is 

unavailable or unwilling to provide a supplemental opinion, OWCP shall refer appellant to a new 

second opinion physician.17 After this and other such further development as deemed necessary, 

it shall issue a de novo decision.18

CONCLUSION

The Board finds that the case is not in posture for decision.
