ISSUE

The issue is whether appellant has met his burden of proof to establish more than 21 percent 

permanent impairment of his left lower extremity (LLE) and 21 percent permanent impairment of 

his right lower extremity (RLE), for which he previously received a schedule award.

FACTUAL HISTORY

On March 9, 2009 appellant, then a 49-year-old mail handler, filed a notice of recurrence 

(Form CA-2a) alleging that on March 6, 2009 he sustained a recurrence of disability of his July 25, 

2008 employment injury.3 He explained that his original injury was never cured and that the status 

of his conditions had remained the same since July 25, 2008. 

By letter dated March 23, 2019, OWCP converted appellant’s recurrence claim to an 

occupational disease claim (Form CA-2), assigned OWCP File No. xxxxxx581. It accepted the 

occupational disease claim for aggravation of left-sided disc herniation at the L4-5 level 

superimposed on a preexisting right-sided herniation at the L5-S1 level and aggravation of lumbar 

radiculopathy superimposed on a preexisting right-sided L5-S1 disc herniation at the L5-S1 level. 

On April 21, 2009 appellant returned to work in a full-time, limited-duty capacity. 

On November 18, 2009 appellant underwent authorized back surgery for revision 

decompression of L4-5, L5-S1 with left-sided L4-5 and L5-S1 foraminotomies with discectomy, 

L4-5. 

On January 27, 2016 appellant filed a claim for a schedule award (Form CA-7). 

In an October 22, 2015 impairment rating report, Dr. Michael M. Cohen, an osteopath

Board-certified in internal medicine and neurology, noted appellant’s “March 6, 2009”

employment injury and the medical records that he reviewed. He conducted a physical 

examination and observed that appellant was unable to perform heel or toe walking. Dr. Cohen 

noted paraspinal muscle spasm and tenderness bilaterally at L4-5. He reported that there was 

limited ankle dorsiflexion due to drop foot involving the RLE. Dr. Cohen also indicated that 

Semmes Weinstein monofilament testing revealed complete anesthesia at 6.65 mgs for the right 

lower extremity and diminished sensitivity to 4.56 mgs for the left lower extremity. He diagnosed 

aggravation of preexisting lumbar discectomy L4-5, repeated herniated disc at L4-5, herniated disc 

at L5-S1, and status post revision decompression at L4-5, L5-S1 with foraminotomy and 

discectomy. 

Dr. Cohen referenced Table 2 of the American Medical Association, Guides to the

Evaluation of Permanent Impairment (A.M.A., Guides)

and The Guides Newsletter, Rating Spinal 

 

3 Appellant has a previously accepted traumatic injury claim under OWCP File No. xxxxxx582 for a July 25, 2008 

employment injury that occurred when he hit his back on a railing while jumping off a porch to avoid two dogs who 

were chasing him. OWCP accepted that claim for contusion of back and subsequently expanded it to include bilateral 

disc herniations at L4-5 superimposed on a preexisting herniation at the L5-S1 level and lumbar radiculopathy. 

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

Nerve Impairment Using the Sixth Edition (July/August 2009) (The Guides Newsletter) and 

determined that appellant had 6 percent LLE permanent impairment due to severe sensory deficits 

at L4;

5 6 percent LLE permanent impairment due to severe sensory deficit at L5;6 4 percent LLE 

permanent impairment due to severe sensory deficit at S1;

7

and 13 percent LLE permanent 

impairment due to moderate motor strength deficit at L58for a combined total of 26 percent 

permanent LLE impairment. Regarding appellant’s RLE, he calculated that appellant had 8 

percent RLE permanent impairment due to very severe sensory deficit at L5;

9 5 percent RLE 

permanent impairment due to very severe sensory deficit at S1;

10 13 percent RLE permanent 

impairment due to very severe motor strength deficit at L5;

11 and 8 percent RLE permanent 

impairment due to moderate motor strength deficit at S1, adjusted to 10 percent,12 for a combined 

total of 32 percent RLE permanent impairment. Dr. Cohen reported that appellant had reached 

maximum medical improvement (MMI) on October 22, 2015. 

On January 29, 2016 Dr. Arnold T. Berman, a Board-certified orthopedic surgeon, serving 

as an OWCP district medical adviser (DMA), reviewed Dr. Cohen’s October 22, 2015 report and 

disagreed with his impairment rating. He contended that Dr. Cohen’s use of “mild/moderate/

severe” categories was excessive and not consistent with the A.M.A., Guides. Utilizing Proposed 

Table 2 of The Guides Newsletter. Dr. Berman determined that appellant had 3 percent LLE 

permanent impairment due to moderate sensory deficits and 5 percent LLE permanent impairment 

due to mild motor deficit at L5 and 2 percent LLE permanent impairment due to moderate sensory 

deficits and 3 percent LLE permanent impairment due to mild motor deficit at S1, when “added 

because they are from the same table,” totaled 13 percent permanent LLE impairment. Regarding 

appellant’s RLE, he calculated that appellant had 3 percent RLE permanent impairment due to

moderate sensory deficits and 13 percent RLE permanent impairment due to severe motor deficits 

at L5 and 2 percent RLE permanent impairment due to moderate sensory deficits and 3 percent 

RLE permanent impairment due to mild motor deficit at S1, when “added because they are from 

the same table,” totaled 21 percent permanent RLE impairment. Dr. Berman reported that 

appellant had reached MMI on October 22, 2015. 

In a June 8, 2016 supplemental report, Dr. Cohen expressed his disagreement with the 

February 22, 2016 DMA report and alleged that his original impairment rating was correct. He 

asserted that, according to the A.M.A., Guides, the Semmes Weinstein Monofilament testing was 

 

5 Dr. Cohen noted grade modifier for functional history (GMFH) of 2 and grade modifier for clinical studies 

(GMCS) of 3 for a net adjustment of +3. 

6 Dr. Cohen reported grade modifiers of 2 (GMFH) and 3 (GMCS) for a net adjustment of +3. 

7 Dr. Cohen noted grade modifiers of 2 (GMFH) and 3 (GMCS) for a net adjustment of +3. 

8 Dr. Cohen reported grade modifiers of 2 (GMFH) and 3 (GMCS) for a net adjustment of +3. 

9 Dr. Cohen noted grade modifiers of 2 (GMFH) and 3 (GMCS) for a net adjustment of +3. 

10 Dr. Cohen reported grade modifiers of 2 (GMFH) and 3 (GMCS) for a net adjustment of +3. 

11 Dr. Cohen noted grade modifiers of 2 (GMFH) and 3 (GMCS) for a net adjustment of +3. 

12 Dr. Cohen reported grade modifiers of 2 (GMFH) and 3 (GMCS) for a net adjustment of +3.

the optimum choice for documenting sensory deficits. Dr. Cohen noted that, according to his 

physical examination, which incorporated the Semmes Weinstein Monofilament testing, 

appellant’s deficits were graded as being mild, moderate, severe, or very severe. 

In reports dated July 25 and September 20, 2016, Dr. Berman indicated that he had 

reviewed Dr. Cohen’s June 8, 2016 report and asserted that Dr. Cohen’s calculations were not 

consistent with appellant’s preoperative or intraoperative findings. 

OWCP found a conflict in the medical opinion evidence and referred appellant for an 

impartial medical examination. In a May 8, 2017 report, Dr. Robert Dennis, a Board-certified 

orthopedic surgeon serving as an impartial medical examiner, discussed appellant’s history of 

injury and reviewed his medical records. He reported that appellant had reached MMI on 

November 18, 2015 approximately one year after appellant’s lumbar surgery. Dr. Dennis related 

appellant’s current complaints of difficulty walking on uneven surfaces and stairs and drop foot 

on both sides. Upon physical examination, he observed that appellant was able to stand on his 

toes, had difficulty maintaining one leg stance and with dorsiflexion of his ankle, and had severe 

weakness of the extension power of the great toe in both feet. Dr. Dennis reported that sensory 

examination of appellant’s bilateral lower extremities revealed no sensory deficit in the L4 nerve 

root and diminished sensation in the L5 and S1 nerve roots. He indicated that appellant had 

diminished sense of light touch to a moderate degree at L5 and S1 with the sensory deficit being 

slightly greater at S1. Dr. Dennis related that manual motor strength testing of the plantarflexion 

was minimally diminished, which would be characterized as mild. He explained that he performed 

the same exact testing on both legs and found similar findings of both legs. 

Utilizing Proposed Table 2 of the A.M.A., Guides and The Guides Newsletter, Dr. Dennis

determined that appellant had five percent RLE permanent impairment due to sensory deficits and 

five percent RLE permanent impairment due to motor deficits at L5 and four percent RLE 

permanent impairment due to sensory deficits and eight percent RLE permanent impairment due 

to motor deficits at S1. He calculated that appellant had a total of 9 percent RLE permanent 

impairment due to sensory deficits at L5-S1 and 13 percent RLE permanent impairment due to 

motor deficits at L5-S1 for a combined total of 22 percent RLE permanent impairment. Regarding 

appellant’s LLE, Dr. Dennis determined that appellant had five percent LLE permanent 

impairment due to sensory deficits and five percent LLE permanent impairment due to motor 

deficits at L5 and four percent LLE permanent impairment due to sensory deficits, and nine percent 

LLE permanent impairment due to motor deficits at S1. Thus, he calculated that appellant had a 

combined sensory deficit of 9 percent and a combined motor deficit of 13 percent, which resulted 

in a combined total of 22 percent LLE permanent impairment. 

On September 11, 2017 Dr. Berman reviewed Dr. Dennis’ May 8, 2017 impartial medical 

examination report and agreed with his impairment rating of 22 percent permanent impairment 

each of the right and left lower extremities. He reported that the date of MMI was

October 22, 2015. 

By decision dated January 22, 2018, OWCP granted appellant a schedule award for 22 

percent permanent impairment of each lower extremity. The award ran for 126.72 weeks from 

October 22, 2015 to March 27, 2018. OWCP noted that the schedule award was based on the 

May 8, 2017 report of Dr. Dennis, the impartial medical examiner. 
5

In an April 18, 2018 decision, an OWCP hearing representative set aside the January 22, 

2018 schedule award decision and remanded the case for OWCP to refer Dr. Dennis’ impartial 

medical report to a different DMA as Dr. Berman was part of the original medical conflict and 

should not review the impartial medical examiner’s IME’s report. 

In a June 22, 2018 report, Dr. Michael M. Katz, a Board-certified orthopedic surgeon 

serving as a DMA indicated that he agreed with Dr. Dennis’ May 8, 2017 impairment rating report, 

with the exception that according to Appendix A on page 605, combining appellant’s 9 percent 

LLE permanent impairment for sensory deficits and 13 percent LLE permanent impairment for 

motor deficits resulted in a combined total of 21 percent LLE permanent impairment. Dr. Dennis 

advised that the correct method for combining these impairment ratings for sensory and motor 

deficits also resulted in 21 percent RLE permanent impairment. 

In June 28, 2018 addendum report, Dr. Dennis indicated that Dr. Katz’ DMA report was 

correct in determining that appellant’s final impairment rating was 21 percent permanent 

impairment to each lower extremity. He revised his previous impairment rating in order to reflect 

the appropriate methodology for combining ratings. Dr. Dennis concluded that appellant had 21 

percent LLE permanent impairment and 21 percent RLE permanent impairment due to his 

accepted spinal injury. 

In a July 23, 2018 report, Dr. Katz noted that he agreed with Dr. Dennis’ impairment rating 

of 21 percent permanent impairment of each lower extremity. He reported that the date of MMI 

was May 8, 2017, the date of Dr. Dennis’ impartial medical examination. 

In a de novo decision dated July 31, 2018, OWCP granted appellant a schedule award for 

21 percent permanent impairment of each lower extremity. The award ran for 120.96 weeks from 

October 22, 2015 to February 13, 2018. OWCP noted that the schedule award was based on the 

May 8, 2017 and June 25, 2018 reports of Dr. Dennis, the impartial medical examiner. 

On August 8, 2018 appellant, through counsel, requested a hearing before a representative 

of OWCP’s Branch of Hearings and Review, which was held on December 18, 2018. 

Appellant submitted an October 3, 2018 report by Dr. Cohen, who related that he had 

reviewed Dr. Dennis’ May 8, 2017 and June 28, 2018 impartial medical reports and Dr. Katz’

June 22, 2017 and July 23, 2018 DMA reports. Dr. Cohen reiterated that according to the A.M.A., 

Guides sensory impairment should be graded through sensibility testing such as Semmes 

Weinstein Monofilament testing (Table 15-3) and motor strength deficit testing should be graded 

on a scale of 0 to 5 according to Table 16-11, page 533. He discussed his disagreement with

Dr. Dennis’ characterization of appellant’s sensory and motor deficits. Dr. Cohen explained that 

he disagreed with Dr. Dennis’ finding that appellant only had a moderate sensory deficit in the left 

L5 nerve root since Dr. Dennis reported that appellant barely felt the filaments of any number 

lower than the stiffest. He also noted his disagreement with Dr. Dennis that appellant had a mild 

motor deficit in the left L5 nerve root since appellant’s motor strength testing reflected severe 

impairment of the left L5 nerve root. Regarding appellant’s right lower extremity, he further noted 

that he would rate appellant with very severe sensory deficit instead of Dr. Dennis’ mild deficit. 

Dr. Cohen referenced the tables and calculations from his previous report and concluded that 
6

appellant had 26 percent permanent impairment of the LLE and 30 percent permanent impairment 

of the RLE.13 

In a December 11, 2018 statement, appellant related that the spinal nerve impairment that 

affected his legs had continued to worsen. He explained that in November 2017 his condition had 

worsened to the point that it was difficult to perform his job as a letter carrier so he decided to 

retire early. 

By decision dated March 4, 2019, an OWCP hearing representative affirmed the July 31, 

2018 schedule award decision. 

LEGAL PRECEDENT

The schedule award provisions of FECA14 and its implementing regulations15 set forth the 

number of weeks of compensation payable to employees sustaining permanent impairment from 

loss or loss of use, of scheduled members or functions of the body. However, FECA does not 

specify the manner in which the percentage of loss of a member shall be determined. For consistent 

results and to ensure equal justice under the law for all claimants, OWCP has adopted the A.M.A., 

Guides as the uniform standard applicable to all claimants and the Board has concurred in such 

adoption.16 As of May 1, 2009, the sixth edition of the A.M.A., Guides, published in 2009, is used 

to calculate schedule awards.17

Neither FECA nor its implementing regulations provide for the payment of a schedule 

award for the permanent loss of use of the back/spine or the body as a whole.18 Furthermore, the 

back is specifically excluded from the definition of organ under FECA.19 The sixth edition of the 

A.M.A., Guides does not provide a separate mechanism for rating spinal nerve injuries as 

impairments of the extremities. Recognizing that FECA allows ratings for extremities and 

precludes ratings for the spine, The Guides Newsletter offers an approach to rating spinal nerve 

impairment consistent with sixth edition methodology. For peripheral nerve impairments to the 

 

13 Dr. Cohen revised his calculations for appellant’s motor deficit for the right S1 nerve. He noted that appellant 

had moderate motor deficit for a default value of eight percent and a GMFH of 2 and a GMCS of 1 for a net adjustment 

of zero.

upper or lower extremities resulting from spinal injuries, OWCP procedures indicate that the 

July/August 2009 edition of The Guides Newsletter is to be applied.20 

Section 8123(a) of FECA provides that, if there is a disagreement between the physician 

making the examination for the United States and the physician of an employee, the Secretary shall 

appoint a third physician (known as a referee physician or impartial medical specialist) who shall 

make an examination.21 This is called an impartial medical examination and OWCP will select a 

physician who is qualified in the appropriate specialty and who has no prior connection with the 

case.22 When there exists opposing medical reports of virtually equal weight and rationale and the 

case is referred to an impartial medical specialist for the purpose of resolving the conflict, the 

opinion of such specialist, if sufficiently well rationalized and based upon a proper factual 

background, must be given special weight.23

ANALYSIS

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

OWCP found a conflict in the medical opinion evidence between appellant’s treating 

physician, Dr. Cohen, and its DMA, Dr. Berman, regarding permanent impairment of the lower 

extremities due to appellant’s accepted spinal injury. It properly referred appellant and the case 

record to Dr. Dennis pursuant to 5 U.S.C. § 8123(a) for an impartial medical examination in order 

to resolve the conflict in medical opinion. In his May 8, 2017 report, Dr. Dennis reviewed 

appellant’s history of injury, the relevant medical evidence, and provided physical examination 

findings. He related that sensory examination revealed no sensory deficits at L4 and diminished 

sensation to a moderate degree in the L5 and S1 nerve roots with slightly greater sensory deficit at 

S1. Utilizing Proposed Table 2 of the A.M.A., Guides and The Guides Newsletter, Dr. Dennis 

determined that appellant had 5 percent RLE permanent impairment due to sensory deficits at L5;

5 percent RLE permanent impairment due to motor deficits at L5; 4 percent RLE permanent 

impairment due to sensory deficits at S1; and 8 percent RLE permanent impairment due to motor 

deficits at S1 for a combined total of 22 percent RLE permanent impairment. Regarding 

appellant’s LLE, he determined that appellant had 5 percent LLE permanent impairment due to 

sensory deficits at L5; 5 percent LLE permanent impairment due to motor deficits at L5; 4 percent 

LLE permanent impairment due to sensory at S1; and 9 percent LLE permanent impairment due 

to motor deficits at S1, which resulted in a combined total of 22 percent LLE permanent 

impairment. In a June 28, 2018 addendum report, Dr. Dennis clarified that, according to the 

appropriate methodology for combining ratings, appellant had a final impairment rating of 21 

percent to each lower extremity.

 

20 Supra note 17 at Chapter 3.700 (January 2010). The Guides Newsletter is included as Exhibit 4.

21 5 U.S.C. § 8123(a); see R.S., Docket No. 10-1704 (issued May 13, 2011); S.T., Docket No. 08-1675 (issued 

May 4, 2009).

The Board finds, however, that Dr. Dennis did not adequately explain his opinion in 

accordance with the relevant standards. While Dr. Dennis provided physical examination findings, 

he failed to provide any discussion of the relevant portion of the A.M.A., Guides and The Guides 

Newsletter he used in finding that appellant had no more than 21 percent RLE and LLE permanent 

impairment.24 He did not adequately explain how he classified appellant’s sensory or motor 

deficits based on severity, did not discuss grade modifiers for functional history or clinical studies, 

and did not adjust the impairment based on the net adjustment formula.25 

In a situation where OWCP secures an opinion from an impartial medical examiner for the 

purpose of resolving a conflict in the medical evidence and the opinion from such examiner 

requires clarification and/or elaboration, OWCP has the responsibility to secure a supplemental 

report from the examiner for the purpose of correcting the defect in the original opinion.26 For the 

above-described reason, the Board finds that the opinion of Dr. Dennis requires clarification. 

Therefore, the case is remanded to OWCP for referral of the case record, a statement of accepted 

facts (SOAF), and, if necessary, appellant, to Dr. Dennis for a supplemental report regarding 

whether appellant has additional permanent impairment of appellant’s lower extremities due to his 

accepted spinal injury. If Dr. Dennis is unable to clarify or elaborate on his original report or if 

his supplemental report is also vague, speculative, or lacking in rationale, OWCP must submit the 

case record and a detailed SOAF to a second impartial medical specialist for the purpose of 

obtaining his rationalized medical opinion on the issue.27 After this and such other further 

development as deemed necessary, OWCP shall issue a de novo decision on this matter.

CONCLUSION

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