ISSUE

The issue is whether appellant has met her burden of proof to establish a left upper 

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

FACTUAL HISTORY

On January 2, 2020 appellant, then a 46-year-old city carrier, filed an occupational disease 

claim (Form CA-2) alleging that she sustained an injury to her arm due to factors of her federal 

employment, including repetitive trauma. She noted that she first became aware of her condition 

on October 10, 2019 and first realized it was caused or aggravated by factors of her federal 

employment on October 17, 2019. On the reverse side of the claim form, the employing

establishment noted that appellant did not stop work but that her work assignment had changed to

preclude use of her left arm.

In support of her claim, appellant submitted a statement dated December 18, 2019 

indicating that, on October 10, 2019, her left arm started to hurt and was swollen, and she noticed 

a knot the size of a grape that was very tender near the crease of her elbow. By October 17, 2019, 

the knot was excruciating to touch, and she observed a vein that had become raised and dark red, 

blue and purple. Appellant immediately sought medical care and was referred to the emergency 

room where she saw Dr. Bassel Atassi, a Board-certified hematologist and oncologist, who 

diagnosed an acute deep vein thrombosis (DVT). She further indicated that after questioning her 

at length about her daily life, Dr. Atassi advised that the clot was caused by her holding her left 

arm in the same position for 7 to 10 hours per day. At that point, appellant realized the condition

was caused by factors of her federal employment, which she indicated included, among other 

things, carrying 10 pounds of letters, magazines, large envelopes, and newspapers on her left arm 

while in a bent position. She explained that the magazines’ spines would usually press against the 

area where she developed the knot, and the worst of her symptoms occurred while she was carrying 

those items. 

In an October 19, 2019 hospital discharge summary, Dr. Ahmad Alwakkaf, a Boardcertified internist, noted that appellant had related a history of left arm pain, swelling, and skin 

changes for one to two weeks. Appellant underwent a venous doppler ultrasound which revealed 

DVT in one of the left brachial veins. Dr. Alwakkaf examined her and diagnosed an acute DVT 

of the left upper extremity. He recommended that appellant remain on anticoagulation medication 

for three months and follow up with Dr. Atassi on November 1, 2019. 

In an undated work slip, Dr. Jerome Anthony, an internist, noted a diagnosis of DVT and 

recommended that appellant remain out of work on November 1, 2019 and return to work on 

November 2, 2019 with restrictions of no use of the left arm. 

In a work slip dated December 12, 2019, Dr. Sheela Manaparambil, a Board-certified

internist, recommended that appellant remain out of work through January 1, 2020, followed by 

light duty for three months.

In a development letter dated February 3, 2020, OWCP informed appellant that the 

evidence submitted was insufficient to establish her claim. It asked herto complete a questionnaire 
3

to provide further details regarding the circumstances of her claimed injury and requested a 

narrative medical report from her treating physician, which contained a detailed description of 

findings and diagnoses, explaining how her work activities caused, contributed to, or aggravated 

her medical condition. OWCP afforded appellant 30 days to respond.

OWCP thereafter received a March 9, 2020 narrative report from Dr. Manaparambil, who 

noted that appellant had been treated in her office on October 17 and November 13, 2019 and 

February 27, 2020. Dr. Manaparambil diagnosed DVT of the left brachial vein and 

thrombophlebitis of the left basilica vein. She outlined appellant’s treatment in the hospital, noting 

that while there, she was also diagnosed with a small pulmonary embolism. Dr. Manaparambil

opined that the DVT was likely precipitated from prolonged immobilization of the arm while 

delivering mail at work. 

By decision dated March 25, 2020, OWCP denied appellant’s occupational disease claim, 

finding that the medical evidence of record was insufficient to establish that her diagnosed medical 

conditions were causally related to the accepted factors of her federal employment.

OWCP continued to receive medical evidence, including hospital records dated 

October 17, 2019. Eileen Moriarity, an advanced practice registered nurse, noted that appellant 

related left arm pain for approximately two weeks with swelling at the medial elbow. Physical 

examination revealed mild swelling and ecchymosis at the medial elbow, tenderness to palpation 

of the medial proximal forearm, medial elbow, and distal upper arm, and an inability to fully extend 

the elbow. The October 17, 2019 hospital records also included a report from Dr. Atassi, who 

noted a history of swelling that started one and one-half weeks ago while appellant was working. 

Dr. Atassi further noted that she was a mail carrier and used her left arm to carry up to 30 pounds 

of letters and packages throughout the course of the day. He examined appellant and reviewed the 

venous doppler study. Dr. Atassi diagnosed a DVT of the left upper extremity, which he opined 

was provoked from trauma to the site while she was working. He recommended ongoing 

anticoagulation therapy for three months.

A report of left upper extremity venous doppler ultrasound dated October 17, 2019

revealed acute DVT in one of the left brachial veins and noncompressability of the left basilica 

vein, concerning for superficial thrombophlebitis.

In a January 16, 2020 letter, Dr. Manaparambil diagnosed DVT of the left upper extremity 

with associated pulmonary embolism. She opined that these conditions likely resulted from 

prolonged immobilization of the arm while appellant delivered mail at work.

On August 11, 2020 appellant, through counsel, requested reconsideration of OWCP’s 

March 25, 2020 decision.

With the request, appellant submitted an additional narrative letter from Dr. Manaparambil 

dated July 27, 2020, which provided responses to various questions posed. Dr. Manaparambil

again noted a diagnosis of DVT of the left upper extremity and that appellant may need long-term 

anticoagulation therapy. When asked how this condition may have been affected by appellant’s

federal work duties, she opined that prolonged immobilization of the left upper arm while working

was a provocative factor for developing DVT. Dr. Manaparambil further noted that appellant’s
4

symptoms are relieved any time she stops prolonged immobilization, and therefore, she would 

benefit from a job that does not involve holding the arm in one position for a prolonged period of 

time. 

By decision dated November 4, 2020, OWCP denied modification of its March 25, 2020

decision.

LEGAL PRECEDENT

An employee seeking benefits under FECA3 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 timely filed within the applicable time 

limitation of FECA,4that an injury was sustained in the performance of duty as alleged, and that 

any disability or medical condition for which compensation is claimed is causally related to the 

employment injury.5 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.6

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

disease claim, a claimant must submit: (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 

casually related to the identified employment factors.7

Causal relationship is a medical question that requires rationalized medical opinion 

evidence to resolve the issue.8 The opinion of the physician must be based upon a complete factual 

and medical background, 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 incident.9

ANALYSIS

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

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

Appellant initially sought care at an emergency department with Dr. Atassi, who diagnosed 

an acute DVT. Dr. Atassi advised that the clot was caused by appellant holding her left arm in the 

same position for 7 to 10 hours per day. However, she did not explain, with sufficient rationale, 

how appellant’s disability was causally related to the accepted employment factors. As noted 

above, the Board has held that reports which lack rationale are of limited probative value on the 

issue of causal relationship.10 Dr. Atassi’s opinion is, therefore, insufficient to establish appellant’s 

claim.

In an October 19, 2019 hospital discharge summary,Dr. Alwakkaf examined appellant and 

diagnosed an acute DVT of the left upper extremity. As well, Dr. Anthony, in an undated note,

provided a diagnosis of DVT and recommended that appellant remain out of work for a period of 

time and advised that she return with restrictions of no use of the left arm. 

Dr. Alwakkaf and Dr. Anthony, however, did not provide an opinion on causal relationship

between appellant’s claimed disability and the accepted employment injury. The Board has held 

that medical evidence that does not offer an opinion regarding the cause of an employee’s 

condition or disability is of no probative value on the issue of causal relationship.11 These reports, 

therefore, are insufficient to establish appellant’s disability claim.

In her January 6, 2020 letter and subsequent supplemental letter dated March 9, 2020,

Dr. Manaparambil provided a diagnosis of DVT of the left upper extremity and opined that 

appellant’s condition “likely” resulted from prolonged immobilization of the arm while she 

delivered mail throughout the day. In a medical narrative dated July 27, 2020, she further 

explained that appellant’s federal work duties, including prolonged immobilization of the left 

upper arm while delivering mail, is a provocative factor for developing DVT. The Board finds 

that Dr. Manaparambil’s opinion that appellant’s employment diagnosed conditions were “most 

likely” caused by the accepted factors of her federal employment is speculative in nature. 12 

Medical opinions that are speculative or equivocal in character are of diminished probative value. 13 

Accordingly, Dr. Manaparambil’s opinion is insufficient to establish appellant’s claim.

Appellant also submitted records from a nurse practitioner. These reports, however, do not 

constitute competent medical evidence because physician assistants, nurse practitioners, and

physical therapists are not considered physicians as defined under FECA.14 Consequently, their 

medical findings and/or opinions will not suffice for purposes of establishing entitlement to 

compensation benefits.15

As appellant has not submitted rationalized medical evidence sufficient to establish a left 

upper extremity condition causally related to the accepted factors of her federal employment, the

Board finds that she has not met her burden of proof.16

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 left upper 

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

14 Section 8101(2) of FECA provides that physician includes surgeons, podiatrists, dentists, clinical psychologists, 

optometrists, chiropractors, and osteopathic practitioners within the scope of their practice as defined by State law.
