ISSUE

The issue is whether appellant has met her burden of proof to establish more than one 

percent permanent impairment of her right upper extremity, for which she previously received a 

schedule award.

FACTUAL HISTORY

On March 30, 2015 appellant, then a 54-year-old tax specialist, filed an occupational 

disease claim (Form CA-2) alleging that she developed cubital tunnel and carpal tunnel syndromes 

of the right upper extremity as a result of repetitive employment duties. She first became aware 

of her condition and of its relationship to factors of her federal employment on 

September 24, 2014. After denial of the claim on June 30, 2015 and February 29, 2016, on 

July 12, 2016 OWCP accepted the claim for right cubital tunnel and carpal tunnel syndromes in 

OWCP File No. xxxxxx263.

3

On November 10, 2014 appellant underwent OWCP-approved anterior transposition of the 

right ulnar nerve and endoscopic carpal tunnel release.

In a report dated March 26, 2015, Dr. Daniel J. Mastella, a Board-certified orthopedic hand 

surgeon, examined appellant for complaints of locking of her small and ring finger. On 

examination of the right upper extremity, he noted full range of motion at the elbow, wrist, and 

digits, with no numbness or tingling in her fingers. At the wrist, Dr. Mastella noted negative 

articular nonarticular, scaphoid shift, and finger extension testing. He noted tenderness to 

palpation of the right ring and small fingers with no locking or catching along with sensitivity over 

the right cubital tunnel incision at the anterior transposed nerve. Thenar strength was 4+/5, first 

dorsal interosseous strength was at 4/5, and flexor pollicis longus strength was at 5/5. Dr. Mastella

diagnosed status post anterior transposition of the ulnar nerve and carpal tunnel release with 

postoperative stenosing tenosynovitis (STS) of the ring finger and small finger. 

On May 12, 2015 appellant followed up with Dr. Mastella for her right upper extremity 

condition. On examination, Dr. Mastella noted that she had full range of motion of the elbow, but

ongoing symptoms attributable to the ulnar nerve on the right. 

On August 3, 2016 appellant filed a claim for a schedule award (Form CA-7).

In an April 12, 2016 report, Dr. Mastella noted that appellant was status post anterior 

transposition of the ulnar nerve and endoscopic carpal tunnel release. On examination of the right 

elbow, he observed 140 degrees of flexion to slight hyperextension. On examination of the right 

wrist, Dr. Mastella observed 60 degrees of flexion and extension, and 80 degrees of pronation and 

supination. On examination of the right digits, he noted full range of motion and extension. 

Dr. Mastella observed a positive Tinel’s sign at the carpal tunnel and a positive Phalen’s test, as 

well as positive elbow compression, cubital tunnel compression, and positive forearm compression 

testing. Referencing the sixth edition of the American Medical Association, Guides to the 

 

3 Under OWCP File No. xxxxxx807, OWCP accepted that appellant sustained a contusion of the right ring finger 

due to a stapler hitting her ring finger on September 24, 2014. It has administratively combined File No. xxxxxx263 

and File No. xxxxxx807, with File No. xxxxxx263 serving as the master file.
3

Evaluation of Permanent Impairment,4 he determined that appellant had eight percent permanent 

impairment of the right upper extremity due to her right-sided anterior transposition of the ulnar 

nerve and endoscopic carpal tunnel release.

In a development letter dated August 9, 2016, OWCP requested that appellant submit a 

detailed medical report from her attending physician, which included a statement that the accepted 

condition had reached maximum medical improvement (MMI) and an impairment rating utilizing 

the appropriate tables of the sixth edition of the A.M.A., Guides. It afforded her 30 days to submit 

the necessary evidence. 

In a letter dated August 11, 2016, OWCP requested that Dr. Mastella submit an addendum 

report which provided a date of MMI, a detailed description of any preexisting permanent 

impairment of the right upper extremity, and rationale for his calculation of eight percent 

permanent impairment of the right upper extremity with reference to the appropriate criteria and 

tables of the A.M.A., Guides. It afforded him 30 days to submit the addendum.

On August 22, 2016 Dr. Mastella responded and noted that appellant was last seen on 

April 12, 2016, at which time she was determined to be at MMI. He noted that no permanent 

impairment of the right upper extremity preexisted her injury. Dr. Mastella explained that criteria 

from the sixth edition of the A.M.A., Guides were referenced to neurologic evaluation guides, 

which were used to determine that appellant had eight percent permanent impairment of the right 

upper extremity.

On December 27, 2016 OWCP referred the case record and a statement of accepted facts 

(SOAF) to Dr. Michael M. Katz, a Board-certified orthopedic surgeon serving as a district medical 

adviser (DMA), for review as to whether appellant sustained permanent impairment of the right 

upper extremity as a result of her accepted conditions.

In a report dated December 28, 2016, the DMA recommended that OWCP contact

Dr. Mastella and afford him the opportunity to submit a detailed, corrective supplemental report. 

He recommended that, if Dr. Mastella was unable to comply, a second opinion evaluation should 

be obtained from a Board-certified specialist in orthopedic surgery or physical medicine and 

rehabilitation. The DMA noted that Dr. Mastella’s August 22, 2016 report could not be accepted 

as probative because he had not provided worksheets, narrative, or calculations to explain how he

had arrived at the eight percent permanent impairment rating.

In a letter dated December 30, 2016, OWCP requested that Dr. Mastella review the 

December 28, 2016 report from the DMA and provide a supplemental report. In an accompanying 

note, it requested that appellant submit the supplemental report from Dr. Mastella within 30 days. 

No report was received.

On May 1, 2017 OWCP referred appellant to Dr. Robert Moskowitz, a Board-certified 

orthopedic surgeon serving as a second opinion examiner, to provide an assessment of appellant’s 

work-related right upper extremity conditions and any resulting permanent impairment. 

In a June 5, 2017 report, Dr. Moskowitz indicated that he had reviewed the SOAF, the 

medical record, and appellant’s history of injury. He noted that appellant’s physical examination 

 

4 A.M.A., Guides (6th ed. 2009).
4

had not demonstrated significant physical findings that would be consistent with her severe 

subjective complaints. While appellant reported pain of 9/10, Dr. Moskowitz noted that appellant 

was two and a half years postsurgery and thus her chronic pain was psychosocial. He opined that 

appellant had reached MMI. Using Table 15-23, page 449 of the sixth edition of the A.M.A., 

Guides, Dr. Moskowitz noted that appellant’s subjective responses to physical testing of her areas 

of claimed sensory changes showed areas that would not be consistent with her carpal tunnel 

syndrome or cubital tunnel syndrome diagnoses. He noted that appellant’s clinical studies 

evidenced a conduction delay, which would be a grade modifier of 1. Because her history and 

physical findings were inconsistent, Dr. Moskowitz assigned grade modifiers of zero, resulting in 

a finding of zero percent permanent impairment of the right upper extremity due to carpal tunnel 

syndrome. Applying the above criteria to appellant’s cubital tunnel syndrome, in which the 

modifiers for history and physical findings were also zero due to inconsistency, he noted that 

conduction delay would qualify for a grade modifier of 2, which would result in one percent 

impairment of the right upper extremity.

On February 27, 2018 OWCP routed Dr. Moskowitz’s June 5, 2017 report, a statement of 

accepted facts (SOAF), and the case file to the DMA for review as to whether appellant sustained 

permanent impairment as a result of her accepted conditions.

In a report dated February 27, 2018, the DMA reviewed the SOAF, the case file, and

Dr. Moskowitz’s June 5, 2017 report. Using the sixth edition of the A.M.A., Guides, Table 15-23, 

page 449, he rated appellant’s ulnar nerve impairment due to clinical studies as grade modifier 2, 

with zero grade modifiers for physical examination (GMPE) and clinical studies (GMCS) due to 

unreliability, resulting in a permanent impairment of one percent. With regard to appellant’s 

median nerve impairment, Dr. Moskowitz rated GMCS of 1, with GMPE and grade modifier for 

functional history (GMFH) of zero, resulting in zero percent permanent impairment. As such, he 

concurred with Dr. Moskowitz’s calculation of permanent impairment of the right upper extremity. 

Dr. Moskowitz noted that the accepted conditions were not eligible for an alternative range of 

motion (ROM) based impairment calculation. He opined that appellant reached MMI on 

June 5, 2017.

By decision dated August 9, 2018, OWCP granted appellant a schedule award for one

percent permanent impairment of the right upper extremity for 3.2 weeks of compensation during 

the period June 5 to 26, 2017. 

On December 18, 2018 appellant, through counsel, requested reconsideration of OWCP’s 

August 9, 2018 decision. With her request, she submitted a letter from Dr. Mastella dated 

November 2, 2018. Dr. Mastella noted that appellant continued to have significant problems, 

including elbow pain at the area of her anterior transposition, ongoing numbness, and tingling in 

the small finger with stiffness. He further noted that he had rendered a permanent impairment 

evaluation of eight percent of the right upper extremity on April 12, 2016. Dr. Mastella argued 

that the A.M.A., Guides offered a limited view as it only rated findings that were easily measured. 

He added that he had used appellant’s complaints to complete his evaluation and had taken into 

account observations of dysfunction in her hand, results of provocative tests, and measurement of 

function of bones, joints, nerves, and tendons. Dr. Mastella concluded that he stood by his rating

of eight percent permanent impairment of appellant’s right upper extremity.

By decision dated April 1, 2019, OWCP denied modification of the decision dated 

August 9, 2018.

LEGAL PRECEDENT

Under section 8107 of FECA5and section 10.404 of the implementing federal regulations,6

schedule awards are payable for permanent impairment of specified body members, functions or 

organs. FECA, however, does not specify the manner in which the percentage of impairment shall 

be determined. For consistent results and to ensure equal justice under the law for all claimants, 

good administrative practice necessitates the use of a single set of tables so that there may be 

uniform standards applicable to all claimants. The A.M.A., Guides has been adopted by the 

implementing regulations as the appropriate standard for evaluating schedule losses.7

The sixth edition of the A.M.A., Guides provides a diagnosis-based method of evaluation 

utilizing the World Health Organization’s International Classification of Functioning, Disability 

and Health (ICF).8 Under the sixth edition, the evaluator identifies the impairment class of 

diagnosis (CDX) condition, which is then adjusted by GMFH, GMPE, and GMCS.9 The net 

adjustment formula is (GMFH - CDX) + (GMPE - CDX) + (GMCS - CDX).10

Permanent impairment due to carpal tunnel syndrome and cubital tunnel syndrome is

evaluated under the scheme found in Table 15-23 (Entrapment/Compression Neuropathy 

Impairment) and accompanying relevant text.11 In Table 15-23, grade modifier levels (ranging 

from zero to four) are described for the categories test findings, history, and physical findings. The 

grade modifier levels are averaged to arrive at the appropriate overall grade modifier level and to 

identify a default rating value. The default rating value may be modified up or down by one 

percent based on functional scale, an assessment of impact on daily living activities.12

OWCP procedures provide that, after obtaining all necessary medical evidence, the file 

should be routed through an OWCP medical adviser for an opinion concerning the nature and 

percentage of impairment in accordance with the A.M.A., Guides, with an OWCP medical adviser 

providing rationale for the percentage of impairment specified.13

ANALYSIS

The Board finds that appellant has not met her burden of proof to establish greater than one

percent permanent impairment of the right upper extremity, for which she has previously received 

a schedule award.

In an April 12, 2016 report, Dr. Mastella noted appellant’s residual symptoms from postcarpal tunnel release and anterior transposition of the ulnar nerve on the right. Referencing the 

sixth edition A.M.A., Guides, he found a permanent impairment of eight percent of the right arm 

related to her right-sided anterior transposition of the ulnar nerve and endoscopic carpal tunnel 

release. On December 28, 2016 the DMA recommended that OWCP contact Dr. Mastella and 

afford him the opportunity to submit a detailed corrective supplemental report as his first report 

did not indicate how the rating method and how it had been calculated. In a letter dated 

November 2, 2018, Dr. Mastella indicated that the A.M.A., Guides offered a limited view as it 

only rated findings that were easily measured. He explained that he had noted appellant’s 

complaints and had taken into account observations of dysfunction, results of provocative tests, 

and measurement of function of bones, joints, nerves, and tendons. Dr. Mastella confirmed his 

rating of eight percent permanent partial impairment of appellant’s right upper extremity. The 

Board notes that, while Dr. Mastella rendered an impairment rating of eight percent and made a 

general reference to the A.M.A., Guides, he did not explain how the sixth edition of the A.M.A.,

Guides supported his impairment rating with references to tables and page numbers. To be of 

probative value, the medical evidence must describe the impairment in sufficient detail so that it 

can be visualized on review and utilized to compute the percentage of impairment in accordance 

with the A.M.A., Guides.

14

 Dr. Mastella failed to adequately explain how the A.M.A., Guides

supported his findings.

15

 Since Dr. Mastella failed to explain how he arrived at an impairment 

rating of eight percent with reference to tables and page numbers of the sixth edition of the A.M.A., 

Guides, his opinion is of limited probative value.

OWCP properly referred appellant for a second opinion evaluation. Dr. Moskowitz, the 

second opinion physician, using Table 15-23, page 449 of the sixth edition of the A.M.A., Guides, 

determined that appellant had zero percent permanent impairment of the right upper extremity due 

to carpal tunnel syndrome and one percent permanent impairment of the right upper extremity due 

to cubital tunnel syndrome. He noted that appellant had GMCS of 1 for carpal tunnel syndrome 

and 2 for cubital tunnel syndrome and he provided his calculations. 

The DMA, using the sixth edition A.M.A., Guides, Table 15-23, page 449, rated appellant’s 

ulnar nerve impairment due to GMCS 2, with zero grade modifiers for GMPE and GMFH due to 

unreliability, which were added and averaged resulting in a permanent impairment of one percent. 

With regard to appellant’s median nerve impairment, he rated a GMCS 1, with zero grade 

modifiers for GMPE and GMFH, which were added and averaged resulting in zero percent

permanent impairment. As such, he concurred with Dr. Moskowitz’s calculation of permanent 

impairment of the right upper extremity.

 

14 See J.T., Docket No. 17-1465 (issued September 25, 2019); G.D., Docket No. 16-1712 (issued August 11, 2017).

15 Id.
7

The Board finds that Dr. Moskowitz and the DMA properly reviewed the medical evidence 

of record and explained their findings with regard to GMCS, GMFH, and GMPE by reviewing the 

medical findings of record and applying them to the criteria set forth in the A.M.A., Guides. The 

Board thus finds that the well-rationalized opinions of the second opinion physician,

Dr. Moskowitz, and the DMA represent the weight of the medical evidence regarding permanent 

impairment of appellant’s right upper extremity.16

Appellant may request a schedule award or increased schedule award at any time based on 

evidence of a new exposure or medical evidence showing progression of an employment-related 

condition resulting in permanent impairment or increased impairment.

CONCLUSION

The Board finds that appellant has not met her burden of proof to establish more than one 

percent permanent impairment of her right upper extremity, for which she previously received a 

schedule award.
