DECISION AND ORDER

Before:

PATRICIA H. FITZGERALD, Deputy Chief Judge

VALERIE D. EVANS-HARRELL, Alternate Judge

JAMES D. McGINLEY, Alternate Judge

JURISDICTION

On June 28, 2022 appellant filed a timely appeal from a January 11, 2022 merit decision 

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.

ISSUE

The issue is whether appellant has met her burden of proof to establish a medical condition 

causally related to the accepted factors of her federal employment.

FACTUAL HISTORY

On June 23, 2021 appellant, then a 56-year-old mail handler, filed an occupational disease 

claim (Form CA-2) alleging that she sustained pain and swelling in her left thumb due to factors 

1

5 U.S.C. § 8101 et seq.
2

of her federal employment, including repetitive grabbing of mail containers throughout each work 

shift. She noted that she first became aware of her condition and realized its relation to her federal 

employment on March 15, 2021. Appellant stopped work on June 23, 2021. 

In an accompanying undated statement, appellant indicated that her current job involved 

culling magazines, a task which required constantly grabbing magazines, cutting straps, removing 

plastic wrap, and placing bundles of magazines into containers. She reported that she previously 

worked on an universal sorting system machine and constantly grabbed mail packages weighing 

up to 70 pounds.

In a June 23, 2021 development letter, OWCP notified appellant of the deficiencies of her 

claim. It advised her of the type of factual and medical evidence needed and provided a 

questionnaire for her completion. OWCP afforded appellant 30 days to submit the necessary 

evidence.

Appellant submitted a June 30, 2021 narrative report from Dr. Lucien Ouellette, a Boardcertified orthopedic surgeon, who indicated that she reported developing left basilar thumb pain 

due to repetitive gripping and grabbing activities at work. Dr. Ouellette advised that, upon physical 

examination, appellant had a bony prominence at the base of the left thumb with tenderness,

particularly along the palmar surface, and the pinch test on the left showed 5/5 strength 

accompanied by pain. He diagnosed arthrosis of the carpometacarpal (CMC) and scaphotrapezium-trapezoid (STT) joints of the left thumb with “first CMC flare.” Dr. Ouellette noted, 

“[t]his appears directly related to her repetitive work duties.”

In a June 30, 2021 attending physician’s report (Form CA-20), Dr. Ouellette listed the date 

of injury as March 15, 2021 and the history of injury as repetitive grabbing and lifting. He 

diagnosed osteoarthritis flare of the CMC joint of the left thumb and checked a box marked “Yes”

to indicate that the diagnosed condition was caused or aggravated by the reported employment 

activity. Dr. Ouellette noted that appellant was partially disabled from March 15 through 

September 15, 2021.

In a June 30, 2021 duty status report (Form CA-17), Dr. Ouellette provided a diagnosis 

“due to injury” of osteoarthritis flare of the CMC joint of the left thumb. He indicated that 

appellant could return to work on June 30, 2021 with restrictions of no lifting, carrying, pushing, 

pulling, simple grasping, or fine manipulation. 

Appellant submitted a July 11, 2021 response to the provided questionnaire in which she 

advised that her current job, which she started approximately a year and half prior, required her to 

reach forward to lift mail, turn her upper body to the side, and place the mail into a container. She 

indicated that her previous job required her to lift mail packages, weighing up to 70 pounds, from 

floor level up to waist level.

By decision dated July 27, 2021, OWCP accepted the employment factors implicated by 

appellant, including repetitively grabbing, lifting, and moving heavy mail packages and 

magazines. However, it denied her claim, finding that the medical evidence of record was

insufficient to establish a diagnosed medical condition causally related to the accepted 
3

employment factors. Consequently, OWCP found that appellant had not met the requirements to 

establish an injury as defined by FECA. 

On August 22, 2021 appellant requested a telephonic hearing before a representative of 

OWCP’s Branch of Hearings and Review.

Appellant submitted an August 5, 2021 work capacity evaluation (Form OWCP-5c) from

Dr. Ouellette who advised that she was unable to return to her usual job, but could perform lightduty work with restrictions of no repetitive motion of her wrists or pinching with her fingers for 

more than three hours per day. 

In an August 31, 2021 letter, Dr. Ouellette indicated that he first evaluated appellant on 

June 30, 2021 at which time he diagnosed CMC and STT osteoarthritis of the left thumb. He 

reported that, as of the date of his letter, she was cleared for return to her regular work duties. 

Dr. Ouellette indicated that the flare of appellant’s arthrosis was due to repetitive gripping and 

grabbing activities over the past two years in her job, which required reaching out to her left side 

and pinching and grabbing mail while sorting. He advised that her left thumb pain substantially 

increased on March 15, 2021 without significant injury and that this pain caused a “sense of 

weakness” in her ability to grip and pinch. Dr. Ouellette opined that, although appellant’s arthritis 

had likely been evolving on a long-term basis, the exacerbation of her pain appeared to be clearly

linked to her work duties and should be fully covered by workers’ compensation. He indicated, 

“[appellant] understands the need for long[-]term modifications in the use of her thumb in order to 

avoid future exacerbations and that these exacerbations would be tied to her regular insurance 

rather than workers’ compensation.”

In an August 31, 2021 Form OWCP-5c, Dr. Ouellette advised that appellant could perform 

her usual job without restrictions.

In a December 20, 2021report, Dr. Ouellette indicated that in his prior reports he had used 

the term “flare” to describe acute onset of pain relative to the underlying arthrosis and that an 

arthrosis was a chronic, gradually evolving process in most individuals. He noted, “[i]n 

[appellant’s] case, this was done while performing her work duties and is directly related to her 

work in the [employing establishment] that involves reaching out to her left side with pinching and 

grabbing of mail while sorting the mail.” Dr. Ouellette opined that this repetitive gripping, 

grabbing, and pinching would overload the CMC and STT joints of the left thumb, resulting in 

appellant’s painful symptoms. He asserted that her medical treatment should be “fully supported”

by the workers’ compensation process. 

By decision dated January 11, 2022, OWCP’s hearing representative affirmed the July 27, 

2021 decision.

LEGAL PRECEDENT

An employee seeking benefits under FECA2 has the burden of proof to establish the 

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

2

Id.
4

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

limitation period of FECA, that an injury was sustained while in the performance of duty, as 

alleged, and that any disability orspecific condition forwhich compensation is claimed is causally 

related to the employment injury.3 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.4

To establish that an injury was sustained in the performance of duty in an occupational 

disease claim, a claimant must submit the following: (1) a factual statement identifying 

employment factors alleged to have caused or contributed to the presence or oc currence 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 identified employmentfactors.5 

Causal relationship is a medical question that requires rationalized medical opinion 

evidence to resolve the issue.6 A physician’s opinion on whether there is causal relationship 

between the diagnosed condition and the implicated employment factor(s) must be based on a 

complete factual and medical background.7 Additionally, the physician’s opinion must be 

expressed in terms of a reasonable degree of medical certainty, and must be supported by medical 

rationale explaining the nature of the relationship between the diagnosed condition and appellant’s 

specific employment factor(s).8

ANALYSIS

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

condition causally related to the accepted factors of her federal employment.

Appellant submitted a June 30, 2021 narrative report from Dr. Ouellette who indicated that 

she reported developing left basilar thumb pain due to repetitive gripping and grabbing activities 

at work. Dr. Ouellette detailed physical examination findings and diagnosed arthrosis of the CMC 

and STT joints of the left thumb with “first CMC flare.” He noted, “[t]his appears directly related 

to her repetitive work duties.” In a June 30, 2021 Form CA-17, Dr. Ouellette listed the date of 

injury as March 15, 2021 and provided a diagnosis “due to injury” of osteoarthritis flare of the

CMC joint of the left thumb. However, while Dr. Ouellette briefly mentioned appellant’s work 

duties and related them to her present left thumb condition, he did not provide a detailed 

description of these work duties, particularly with respect to the extent they were performed over 

time. The Board has held that a report is of limited probative value regarding causal relationship 

if it does not contain medical rationale explaining how an employment activity could have caused 

or aggravated a medical condition.9 Therefore, this evidence is insufficient to establish the claim. 

In a June 30, 2021 Form CA-20, Dr. Ouellette listed the date of injury as March 15, 2021 

and the history of injury as repetitive grabbing and lifting. He diagnosed osteoarthritis flare of the 

CMC joint of the left thumb and checked a box marked “Yes” to indicate that the diagnosed 

condition was caused or aggravated by the reported employment activity. 10 Dr. Ouellette provided 

no rationale for his opinion on causal relationship. The Board has held that when a physician’s 

opinion on causal relationship consists only of checking “Yes” to a form question, without more by 

the way of medical rationale, that opinion is of limited probative value and is insufficient to establish 

causal relationship.11 As such, this report is insufficient to establish the claim.

Appellant also submitted an August 31, 2021 report from Dr. Ouellette who indicated that 

the flare of her arthrosis was due to repetitive gripping and grabbing activities over the past two 

years in her job, which required reaching out to her left side and pinching and grabbing mail while 

sorting. Dr. Ouellette opined that, although appellant’s arthritis had likely been evolving on a 

long-term basis, the exacerbation of her pain in March 2021 appeared to be clearly linked to her 

work duties. In a December 20, 2021 letter, he indicated that in his prior reports he had used the 

term “flare” to describe acute onset of pain relative to the underlying arthrosis and that an arthrosis 

was a chronic, gradually evolving process in most individuals. Dr. Ouellette noted, “[i]n 

[appellant’s] case, this was done while performing her work duties and is directly related to her 

work in the [employing establishment] that involves reaching out to her left side with pinching and 

grabbing of mail while sorting the mail.” He opined that this repetitive gripping, grabbing, and 

pinching would overload the CMC and STT joints, resulting in her painful symptoms. However,

Dr. Ouellette did not provide a detailed description of appellant’s work duties, nor did he

sufficiently explain his finding that appellant’s increased left thumb symptoms in March 2021 

were not solely due to the natural progression of her preexisting arthritic condition. As noted 

above, the Board has held that a report is of limited probative value regarding causal relationship 

if it does not contain sufficient medical rationale explaining how an employment activity could 

have caused or aggravated a medical condition.12 Therefore, this evidence is insufficient to 

establish the claim. 

Appellant submitted an August 5, 2021 Form OWCP-5c from Dr. Ouellette who advised 

that she was unable to return to her usual job, but could perform light-duty work with restrictions 

of no repetitive motion of her wrists or pinching with her fingers for more than three hours per 

day. In an August 31, 2021 Form OWCP-5c, Dr. Ouellette advised that she could perform her

usual job without restrictions. However, these reports do not contain an opinion on the cause of 

appellant’s diagnosed medical conditions. The Board has held that medical evidence that does not 

offer an opinion regarding the cause of an employee’s condition is of no probative value on the 

issue of causal relationship.

13

 Therefore, these reports are insufficient to establish the claim.

As the medical evidence of record is insufficient to establish a medical condition causally

related to the accepted factors of federal employment, the Board finds that appellant has not met 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 medical 

condition causally related to the accepted factors of her federal employment.
