DECISION AND ORDER

Before:

ALEC J. KOROMILAS, Chief Judge

JANICE B. ASKIN, Judge

JAMES D. McGINLEY, Alternate Judge

JURISDICTION

On November 23, 2022 appellant filed a timely appeal from an October 13, 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 met his burden of proof to establish a brain tumor causally 

related to the accepted employment exposure.

FACTUAL HISTORY

On December 5, 2021 appellant, then a 37-year-old international cooperation volunteer, 

filed an occupational disease claim (Form CA-2) alleging that he developed a brain tumor due to 

his exposure to residual radiation from the Chernobyl nuclear incident while spending three

months training in Chernigov and 24 months on site at Khartsyzsk. He first became aware of his 

condition on June 1, 2021, but did not realize that it had been caused or aggravated by his 

employment until November 15, 2021. 

In support of his claim, appellant submitted discharge and hospital records dated from 

June 9 through 18, 2021 from a hospital, New Zealand regarding his treatment of a large right 

frontal dural-based lesion, with right craniotomy and excision of tumor. The records indicated that 

appellant had presented with a progressive headache, worsening over the last month, with one 

month of concentration issues, one week of personality changes, with probable quickly-recovering 

absence-type seizures, and a few days of vomiting. Appellant also submitted a World Health 

Organization treatise on doses of ionizing radiation and the increased risk of death from solid 

cancers.

A July 23, 2021 surgical report noted that appellant underwent right craniectomy for 

infected bone flap. The report noted that appellant had undergone a prior craniotomy for resection 

of a very large right frontal meningioma. Following surgery there was evidence of gross infection 

of the bone flap.

In a letter dated December 9, 2021, Carlotta Smith, a nurse, provided an agency statement 

noting that appellant had served for two years in Ukraine from 2010 to 2012 and that he had filed 

a FECA claim alleging that his meningioma brain tumor was due to his exposure to radiation while 

on mission. She advised OWCP that she was unable to access appellant’s Peace Corp chart and, 

thus, his prior medical history was unknown. Ms. Smith detailed appellant’s work history, noting 

that he had lived 80 kilometers from the area in Ukraine where the Chernobyl Nuclear disaster 

occurred, and where a low level of radiation remained. She noted appellant’s diagnosis of the 

brain tumor and subsequent treatment. Ms. Smith also reported that appellant continued to live in 

New Zealand and planned to move back to the United States. 

On December 10, 2021 OWCP received a narrative statement wherein appellant noted his 

address in Auckland, New Zealand. Appellant alleged that he had been diagnosed with large dural 

right frontal lobe brain tumor and he had been informed by his physicians that the tumor might 

have been growing for one to two years undetected. He related his Peace Corps history in Ukraine 

including his training and where he lived. Appellant attributed his brain tumor to his low-level 

radiation exposure while working for the Peace Corps in Ukraine. He further related that the 

removal of his tumor had been covered by New Zealand’s national healthcare and that he would

require medical care and annual magnetic resonance imaging scans upon his return to the United 

States.

In a development letter dated December 10, 2021, OWCP informed appellant that the 

evidence of record was insufficient to establish his occupational disease claim. It advised him 

regarding the medical and factual evidence required to establish his claim. In a development letter 

of even date, OWCP requested the employing establishment to comment on appellant’s statements 

and whether it agreed with his allegations. It also requested that the employing establishment 

provide records regarding appellant’s radiation exposure. OWCP afforded both parties 30 days to 

provide the information requested. 
3

In response to OWCP’s development letter, appellant asserted that OWCP’s request that 

he provide a letter from a medical professional that his tumor had been caused by his service in 

Ukraine was unreasonable. He alleged that his claim was similar to the link between smoking and 

lung cancer. Appellant argued that it was well known that radiation causes tumors and that he had 

been exposed to low level radiation while in Ukraine.

A December 21, 2021 employing establishment statement from Ms. Smith reiterated that 

the original Peace Corps medical records for appellant were not located at the Federal Record 

Center, therefore whatever had been uploaded completed the medical record documentation.

On April 6, 2022 OWCP referred appellant, together with a statement of accepted facts, 

medical record, and list of questions, to Dr. Josef A. Ottowicz, a Board-certified neurologist, to 

provide an opinion on whether the diagnosed brain tumor was causally related to accepted 

employment factors. 

In a May 10, 2022 memorandum of telephone call (Form CA-110) appellant requested that 

the second opinion appointment be cancelled as he was living in New Zealand and could nottravel 

due to his brain surgery and cost of ticket to the United States. In e-mail correspondence of even 

date, OWCP advised appellant that it had cancelled his second opinion evaluation appointment. It 

asked when he would be able to travel back to the United States so that a second opinion evaluation

could be scheduled.

By decision dated October 13, 2022, OWCP denied appellant’s claim finding that he failed 

to establish that the diagnosed medical condition was causally related to the accepted employment 

exposure. 

LEGAL PRECEDENT

FECA provides that an injury or illness sustained by a Peace Corps volunteer when he or 

she is outside the United States shall be presumed to have been sustained while in the performance 

of duty and proximately caused by federal employment. This presumption may be rebutted by 

evidence demonstrating that the injury or illness: (1) was caused by the volunteer’s willful 

misconduct or intent to bring about injury to self or another; (2) was proximately caused by the 

volunteer’s intoxication by alcohol or illegal drugs; (3) preexisted the period of service abroad; or 

(4) manifested symptoms of, or consequent to, a preexisting congenital defect or abnormality. 2 If 

the presumption is rebutted by evidence showing that the injury or illness preexisted the period of 

service abroad or manifested symptoms of, or consequent to, a preexisting congenital defect or 

abnormality, the volunteer may still prove his or her claim and be entitled to compensation if he 

or she submits substantial, probative and rationalized evidence establishing that the injury or 

illness was proximately caused or materially aggravated, accelerated or precipitated by factors or 

conditions of Peace Corps service.3

Id. at § 8142(c)(3); 20 C.F.R. § 10.730(a);see also M.C., Docket No. 19-0624 (issued December 8, 2020); S.C., 

Docket No. 14-0383 (issued May 28, 2014).

3

20 C.F.R. § 10.730(b), (c).
4

While Peace Corps volunteers are normally entitled to the presumption that an injury or 

illness sustained while abroad is proximately related to federal employment, the presumption will 

not arise if no injury or illness is diagnosed. Without a firm medical diagnosis, it is not possible 

to ascertain whether the condition was preexisting or congenital.4

ANALYSIS

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

The evidence establishes that appellant served in the Peace Corps from 2010 to 2012 in 

Ukraine and that he has alleged that his meningioma brain tumor was due to his exposure to low 

level radiation while serving in Ukraine. The medical evidence of record consists of reports from 

a hospital in New Zealand diagnosing very large fontal meningioma. 

FECA provides that an injury or illness sustained by a Peace Corps volunteer when he or 

she is outside the United States shall be presumed to have been sustained while in the performance 

of duty and proximately caused by federal employment. 5 The presumption under section 

8142(c)(3) of FECA is applicable in this case.

OWCP failed to apply the presumption as outlined by FECA and its implementing 

regulations. Therefore, the case will be remanded for OWCP to further develop the claim 

consistent with the appropriate procedures. Following this and other such further development as 

deemed necessary, OWCP shall issue a de novo merit decision of appellant’s claim.

CONCLUSION

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