DECISION AND ORDER 

Before: 

CHRISTOPHER J. GODFREY, Chief Judge 

COLLEEN DUFFY KIKO, Judge 

JAMES A. HAYNES, Alternate Judge 

JURISDICTION 

On January 9, 2015 appellant, through counsel, filed a timely appeal from an October 27, 

2014 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 met his burden of proof to establish an occupational 

disease in the performance of duty. 

FACTUAL HISTORY 

On February 14, 2014 appellant, then a 47-year-old carrier, filed an occupational disease 

claim alleging that he developed a right foot condition in the performance of duty. He alleged 

that delivering parcels of mail, entering and exiting his postal vehicle, walking to and from 

 1

 5 U.S.C. § 8101 et seq. 
2

customer’s residences, and walking up and down stairs caused the need for amputation of his 

right fourth toe and metatarsal bone, right ankle injury, and aggravation of his diabetes with 

neuropathy. Appellant stopped work on February 5, 2014 and returned to work on 

February 10, 2014. He then stopped work again on February 21, 2014. 

In a March 25, 2014 statement, the employing establishment controverted appellant’s 

claim because he failed to submit medical evidence establishing causal relationship between a 

diagnosed condition and his federal employment. 

By letter dated April 2, 2014, OWCP notified appellant that no medical documentation 

was received and advised him of the type of factual and medical evidence needed to establish the 

claim. 

In an April 20, 2014 statement, appellant advised that driving a two-ton truck, delivering 

parcels of mail up to 100 pounds, climbing in and out of the postal truck, climbing steps to 

deliver mail, constant weight bearing, and walking under pressure to deliver timely caused or 

contributed to his injury. 

In a February 27, 2014 report, Dr. Harold Brem, a Board-certified surgeon, advised that 

appellant was under his care for acute osteomyelitis and that he first saw him two days prior for 

amputation of his right fourth toe and metatarsal head. He noted that appellant had a limbthreatening lesion on his foot caused by long-term diabetes and lots of walking on the job. 

In a March 6, 2014 report, Dr. Michael Castellano, a Board-certified surgeon, advised 

that appellant had a history of diabetes with neuropathy. On physical examination he noted that 

appellant’s right foot had three toes and a wound at the amputation site of the fourth toe. 

Dr. Castellano further noted that there was minimal edema, derangement of the three remaining 

toes, a charcot joint in the ankle, and evidence of weight bearing being transferred onto his 

medial ankle. He diagnosed type 2 diabetes with charcot joint of the right foot. Dr. Castellano 

opined that appellant’s disease was caused and aggravated by long-term activity with walking 

and microtrauma to his right foot from getting in and out of elevated distances, walking long 

distances, and carrying heavy packages. He opined that appellant’s diabetes and neuropathy 

would eventually lead to the breakdown of his ankle joint and the skin leading to chronic 

infections and amputation of the lower leg. Dr. Castellano advised that appellant was not able to 

maintain the activity level his position required.2

In a June 17, 2014 decision, OWCP denied the claim because the medical evidence was 

insufficient to establish that the diagnosed condition was caused by factors of his employment. 

By letter dated July 21, 2014, appellant’s counsel requested reconsideration. 

In an April 23, 2014 report, Dr. Nick Michelakis, Board-certified in internal medicine 

and cardiovascular disease, advised that appellant was diagnosed with diabetes at age 38. He 

noted that in 2009 appellant had his first toe on the right foot amputated, which caused him to

have distorted balance. Dr. Michelakis further noted that in 2009 appellant underwent a 

coronary artery bypass graph. He advised that appellant’s diabetes had not been adequately 

controlled over the past nine years due to carbohydrate ingestion in his diet and inconsistent 

follow-up with his medical provider and diabetologist. Dr. Michelakis noted that in early 2014 

appellant developed gangrene due to uncontrolled diabetes, which resulted in digit amputation on 

the right foot. He opined that appellant’s recent transmetatarsal foot amputation led to 

destabilization of his right ankle which likely began in 2009 with his initial first toe amputation. 

Dr. Michelakis further opined that appellant’s unstable ankle, reduced left ventricular ejection 

fraction of 32 percent, and his uncontrolled diabetes made him unable to perform his duties. He 

advised that appellant was no longer employed by the employing establishment and was 

attending to his health full time. 

In a June 3, 2014 addendum, Dr. Michelakis opined that appellant’s preexisting diabetes 

and repetitive stress of employment led to his current right foot and ankle injuries. He further 

opined that repetitive motions, weight bearing, and ambulation brought on and aggravated his 

condition. 

By decision dated October 27, 2014, OWCP denied appellant’s claim because the 

evidence was insufficient to establish that his condition was caused by factors of his 

employment. 

LEGAL PRECEDENT 

An employee seeking benefits under FECA has the burden to establish the essential 

elements of his or her claim, including the fact 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, that an injury was sustained in the performance of duty as alleged, and that any 

disabilities and/or specific conditions for which compensation is claimed are 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

Whether an employee actually sustained an injury in the performance of duty begins with 

an analysis of whether fact of injury has been established. To establish an occupational disease 

claim, an employee 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 

causally related to the employment factors identified by the employee.5

 

Causal relationship is a medical issue and the evidence generally required to establish 

causal relationship is rationalized medical opinion evidence. Rationalized medical opinion

evidence is generally required to establish causal relationship. The opinion of the physician must 

be based on 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 factors identified by the claimant.6

 

The weight of medical evidence is determined by its reliability, its probative value, its 

convincing quality, the care of analysis manifested and the medical rationale expressed in 

support of the physician’s opinion.7

 

ANALYSIS 

It is not disputed that appellant’s job delivering parcels required getting in and out of his 

work vehicle, walking, and carrying packages. However, the medical evidence is insufficient to 

establish that these duties caused or aggravated his diagnosed conditions. 

In his March, 2014 report, Dr. Castellano advised that appellant had a history of diabetes 

with neuropathy. He assessed type 2 diabetes with charcot joint of the right foot. Dr. Castellano 

opined that appellant’s disease was caused and aggravated by long-term activity with walking 

and microtrauma to his right foot from getting in and out of his elevated vehicle, walking long 

distances, and carrying heavy packages. He advised that appellant could not maintain the type of 

activity his position required. This report is insufficient to discharge appellant’s burden of proof 

because it lacks reasoning to explain how the work duties identified by Dr. Castellano caused or 

aggravated appellant’s condition. While appellant’s amputation occurred during a period of 

employment, this fact alone does not establish that it was employment related.8

 The need for 

medical rationale explaining how particular job duties contributed to appellant’s condition is 

particularly important because appellant has preexisting conditions, such as diabetes, that could 

be the cause of his claimed condition. 

In his February 27, 2014 report, Dr. Brem advised that appellant was under his care for 

acute osteomyelitis and that he recently underwent a procedure to amputate his right fourth toe 

and metatarsal head. He found that appellant had a limb-threatening lesion on his foot caused by 

long-term diabetes and walking on the job. Although Dr. Brem partially attributes appellant’s 

condition to walking on the job, he does not provide any medical rationale. The Board has long 

held that medical opinions not containing rationale to support causal relation are of diminished 

probative value and generally insufficient to meet appellant’s burden of proof.9

 This report is of 

limited probative value. 

In his April 23, 2014 report, Dr. Michelakis advised that in early 2014 appellant 

developed gangrene as a result of uncontrolled diabetes. This required amputation on the right

during a period of employment nor the belief that the disease or condition was caused or aggravated by employment 

factors or incidents is sufficient to establish causal relationship).

foot. Dr. Michelakis opined that appellant’s recent transmetatarsal foot amputation led to 

destabilization of his right ankle which had likely begun in 2009 with his first toe amputation. 

He further opined that appellant’s unstable ankle, reduced left ventricular ejection fraction, and 

his uncontrolled diabetes made him unable to perform his job duties. In his June 3, 2014 

addendum, Dr. Michelakis opined that appellant’s preexisting diabetes and repetitive stress of 

employment led to his current right foot and ankle condition. He further opined that repetitive 

motions, weight bearing, and ambulation brought on and aggravated his condition. Although 

Dr. Michelakis attributes appellant’s condition to factors of his employment, he does not provide 

medical rationale explaining how employment contributed to appellant’s condition, nor does he 

discuss with any specifics the duties of appellant’s job which contributed to or aggravated the 

diabetic conditions. He did not explain his change of opinion from his earlier April 23, 2014 

report where he attributed appellant’s condition to uncontrolled diabetes and gangrene. As 

noted, the need for rationale is particularly important where the evidence shows that appellant 

has a serious diabetic condition that also contributed to his foot condition. 

On appeal appellant’s counsel argued that the medical evidence submitted established 

that his diagnosed condition was causally related to factors of his employment. However, 

appellant has not submitted medical evidence explaining how the specific work factors caused or 

contributed to the diagnosed condition. The physician must accurately describe appellant’s work 

duties and also medically explain the process by which these specific duties would have caused 

or aggravated his condition.10 Because appellant has not provided such medical opinion 

evidence in this case, he has failed to meet his burden of proof. 

Appellant may submit new evidence or argument as part of a formal 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 did not meet his burden of proof to establish an 

occupational disease in the performance of duty.

identified by the claimant to the claimant’s condition, with stated reasons by a physician). See also S.T., Docket No.
