DECISION AND ORDER 

Before: 

CHRISTOPHER J. GODFREY, Chief Judge 

PATRICIA H. FITZGERALD, Deputy Chief Judge 

COLLEEN DUFFY KIKO, Judge 

JURISDICTION 

On October 13, 2015 appellant filed a timely appeal of a July 31, 2015 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 the case. 

ISSUE 

The issue is whether appellant met her burden of proof to establish an occupational 

disease due to factors of her federal employment. 

FACTUAL HISTORY 

On October 10, 2014 appellant then a 53-year-old mail distribution clerk, filed an 

occupational disease claim (Form CA-2), alleging that she developed severe pain in her hand and 

loss of use of her thumb while performing repetitive work duties which included sorting raw

mail, letters, flats, and parcels. She first became aware of her condition on July 10, 2014 and 

realized it was causally related to her employment on August 21, 2014. Appellant did not stop 

work. 

Appellant submitted a report from a physician assistant, dated August 21, 2014, which 

reflected a diagnosis of carpal tunnel syndrome and a request for a nerve conduction study and 

electromyogram (EMG). 

By letter dated November 17, 2014, OWCP advised appellant of the type of evidence 

needed to establish her claim, particularly requesting that she submit a physician’s reasoned 

opinion addressing the relationship of her claimed condition and specific employment factors. 

Appellant submitted a statement dated December 10, 2014. She noted working as a clerk 

for the employing establishment since October 22, 1988 and her duties included boxing mail, 

pulling down manual letters in carrier sequence, and sorting manual flats. Appellant also worked 

as a trainer and window clerk where she taught others to use an automated machine, keyed in zip 

codes, and received and distributed packages. She reported falling in 2007 during an ice storm 

and sustained a hairline fracture in her wrist. 

In a December 23, 2014 decision, OWCP denied the claim as there was no medical 

evidence establishing a diagnosed condition related to the work factors. 

On May 18, 2015 appellant requested reconsideration. In an undated statement she 

asserted that she had developed carpal tunnel syndrome and locking of her thumb as a result of 

performing her repetitive clerk duties. Appellant submitted another report from a physician 

assistant dated August 21, 2014, where she had been treated for numbness of the right thumb and 

index finger. The physician assistant diagnosed right thumb stenosing tenosynovitis. In a 

September 25, 2014 report, the physician assistant noted appellant’s complaints of bilateral hand 

pain and paresthesias and that an EMG revealed severe right carpal tunnel syndrome. 

Appellant was treated on September 16, 2014 by Dr. Robert Wilson, Board-certified in 

physical medicine and rehabilitation, for carpal tunnel syndrome, shoulder joint pain, neck pain, 

and calcified tendinitis of the shoulder. She reported triggering of her right digit, distal hand 

numbness with decreased strength. Dr. Wilson performed an EMG which revealed severe 

bilateral carpal tunnel syndrome, significant motor axonopathy of the right hand, right ulnar 

slowing neuropathy of the elbow, and tenosynovitis. 

Appellant was also seen by Dr. Aldridge Mack, III, a Board-certified orthopedist, on 

September 25, 2014, who diagnosed carpal tunnel syndrome. In a later report dated June 29, 

2015, Dr. Mack treated her for bilateral carpal tunnel syndrome with right trigger thumb. He 

noted that the EMG revealed severe right and moderate left carpal tunnel syndrome. Dr. Mack 

noted examination findings of numbness and tingling in the right hand, painful nodule at the A1 

pulley, locking, and catching in the right thumb, with positive Tinel’s sign on the right. He 

diagnosed bilateral carpal tunnel syndrome, right worse than left, and right trigger thumb. 

Dr. Mack recommended right open carpal tunnel release and a right A1 pulley release of the 

right thumb.

In a decision dated July 31, 2015, OWCP denied the claim finding that the medical 

evidence failed to provide a rationalized opinion explaining the causal relationship between the 

diagnosed condition and employment factors. 

LEGAL PRECEDENT 

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

essential elements of his or her claim. When an employee claims that he or she sustained an 

injury in the performance of duty, he or she must submit sufficient evidence to establish that he 

or she experienced a specific event, incident or exposure occurring at the time, place, and in the 

manner alleged. Appellant must also establish that such event, incident, or exposure caused an 

injury.2 

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

disease claim, a claimant must submit the following: (1) medical evidence establishing the 

presence or existence of the disease or condition for which compensation is claimed; (2) factual 

statement identifying employment factors alleged to have caused or contributed to the presence 

or occurrence of the disease or condition; and (3) medical evidence establishing that the 

employment factors identified by the claimant were the proximate cause of the condition for 

which compensation is claimed or, stated differently, medical evidence establishing that the 

diagnosed condition is causally related to the employment factors identified by the claimant. 

The medical evidence required to establish causal relationship is generally rationalized medical 

opinion evidence. Rationalized medical opinion evidence is medical evidence which includes a 

physician’s rationalized opinion on the issue of whether there is a causal relationship between the 

claimant’s diagnosed condition and the implicated employment factors. 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 

identified by the claimant.3

ANALYSIS 

It is undisputed that appellant’s work duties as a mail processing clerk included 

repetitively sorting mail, letters, flats, and parcels. It is also not disputed that she was diagnosed 

with a bilateral carpal tunnel syndrome and right trigger finger. However, appellant has not 

submitted sufficient medical evidence to establish that the diagnosed conditions are causally 

related to her employment factors. On November 17, 2014 OWCP advised her of the type of 

medical evidence needed to establish her claim, but she has failed to provide sufficient medical 

evidence to establish that any of these conditions are causally related to the accepted 

employment factors.

243, 247 (1967) (traumatic injury). See generally John J. Carlone, 41 ECAB 354 (1989); Elaine Pendleton, 40 

ECAB 1143 (1989).

Appellant submitted a September 16, 2014 report from Dr. Wilson who treated her for 

carpal tunnel syndrome, shoulder joint pain, neck pain, and calcified tendinitis of the shoulder. 

Dr. Wilson diagnosed triggering of her right digit, distal hand numbness with decreased strength, 

and following an EMG severe bilateral carpal tunnel syndrome, significant motor axonopathy of 

the right hand, right ulnar slowing neuropathy of the elbow, and tenosynovitis. His report, 

however, failed to provide a cause of these conditions4

 nor did he reflect an understanding of her 

work factors.5

 

Appellant was treated by Dr. Mack, who diagnosed bilateral carpal tunnel syndrome, 

right worse than left, and right trigger thumb. Dr. Mack noted that appellant worked as a 

supervisor at the employing establishment for 27 years. He recommended right open carpal 

tunnel release and a right A1 pulley release of the right thumb. However, Dr. Mack’s reports are 

also insufficient to establish the claim as he did not specifically address whether appellant’s 

employment activities had caused or aggravated the diagnosed medical condition.6 He did not 

explain the process by which repetitively sorting raw mail, letters, flats, and parcels would cause 

or aggravate the diagnosed conditions. 

Appellant submitted reports from a physician assistant. The Board has held that 

treatment notes signed by a physician assistant are not considered medical evidence as these 

providers are not considered physicians under FECA.7 

Therefore, the Board finds that appellant has failed to submit sufficient medical evidence 

to establish her claim. 

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 failed to meet her burden of proof to establish an 

occupational disease due to factors of her federal employment. 

 4 A.D., 58 ECAB 149 (2006) (medical evidence which does not offer any opinion regarding the cause of an 

employee’s condition is of limited probative value on the issue of causal relationship). 

5 Frank Luis Rembisz, 52 ECAB 147 (2000) (medical opinions based on an incomplete history or which are 

speculative or equivocal in character have little probative value).

7 See David P. Sawchuk, 57 ECAB 316 (2006) (lay individuals such as physician assistants, nurses and physical 

therapists are not competent to render amedical opinion under FECA); 5 U.S.C. § 8101(2) (this subsection defines a 

“physician” as surgeons, podiatrists, dentists, clinical psychologists, optometrists, chiropractors, and osteopathic 

practitioners within the scope of their practice as defined by State law).
