DECISION AND ORDER

Before:

ALEC J. KOROMILAS, Chief Judge

PATRICIA H. FITZGERALD, Alternate Judge

VALERIE D. EVANS-HARRELL, Alternate Judge

JURISDICTION

On March 17, 2020 appellant filed a timely appeal from a February 28, 2020 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 has met his burden of proof to establish more than three 

percent permanent impairment of his left lower extremity, for which he previously received a 

schedule award.

 

1 5 U.S.C. § 8101 et seq.

FACTUAL HISTORY

On August 3, 2018 appellant, then a 46-year-old field intelligence agent, filed a traumatic 

injury claim (Form CA-1) alleging that, on August 2, 2018 when arising from his chair, he caught 

his left foot on torn carpet causing his left knee to pop while in the performance of duty. OWCP 

accepted the claim for a peripheral tear of the medial meniscus of the left knee. On October 1, 

2018 appellant underwent an OWCP-authorized left knee arthroscopic partial lateral 

meniscectomy and loose body removal. He returned to work in a modified limited-duty position 

on November 19, 2018 and subsequently returned to full-duty work on February 7, 2019. 

In a report dated March 13, 2019, Dr. Michael Mrochek, Board-certified in physical 

medicine and rehabilitation, reviewed appellant’s history of injury and medical record, noting that 

appellant continued to experience pain in the left knee. On physical examination, he observed 

mild joint line tenderness medially in the left knee, as well as bilateral patellar crepitus. 

Dr. Mrochek performed three measurements of the left knee active range of motion (ROM) from 

0 to 115 degrees. He diagnosed a peripheral tear of the medial meniscus of the left knee. Referring 

to the sixth edition of the American Medical Association, Guides to the Evaluation of Permanent 

Impairment (A.M.A., Guides),2 Dr. Mrochek rendered an impairment rating based on the ROM

method. Referencing Table 16-23, page 549, he noted a five-degree flexion contracture. 

Dr. Mrochek explained that the ROM method resulted in 10 percent left lower extremity 

permanent impairment. Referencing Table 16-3, page 509, he noted that the diagnosis-based 

method (DBI) applied to a partial lateral meniscectomy constituted a class of diagnosis (CDX) at 

the class 1 level, grade C, with a default value of two percent left lower extremity permanent 

impairment. Dr. Mrochek calculated a grade modifier for functional history (GMFH) of 1, as well 

as a grade modifier for physical examination (GMPE) of 1. The grade modifier for clinical studies 

(GMCS) was not used. Application of the net adjustment formula did not require movement from 

the default value of two percent under the DBI method. Dr. Mrochek explained that, as the two

percent permanent impairment calculated under the DBI method was the lesser of the two methods, 

appellant had 10 percent permanent impairment of the left lower extremity based on the ROM 

method. He stated that the date of maximum medical improvement (MMI) was February 7, 2019. 

On March 15, 2019 appellant filed a claim for a schedule award (Form CA-7). 

On June 6, 2019 OWCP referred the record to Dr. Arthur S. Harris, a Board-certified 

orthopedic surgeon serving as a district medical adviser (DMA), for review and rating of 

appellant’s permanent impairment of the left lower extremity in accordance with the sixth edition 

of the A.M.A., Guides.

In a June 10, 2019 report, Dr. Harris reviewed a statement of accepted facts and the medical 

record, including the March 13, 2019 report of Dr. Mrochek. He advised that the diagnosis of 

status post left knee arthroscopic partial lateral meniscectomy and loose body removal had been 

established. Using the DBI method with reference to appellant’s left knee condition, the DMA 

concurred with Dr. Mrochek that, under the sixth edition of the A.M.A., Guides, Table 16-3, page 

509, appellant had two percent permanent impairment of the left lower extremity using the DBI 

 

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

method. He noted that Dr. Mrochek had calculated appellant’s impairment using both the DBI 

and ROM rating methods. Referencing section 16.7, page 543, of the A.M.A., Guides, the DMA 

explained that the A.M.A., Guides allow for the ROM method to be used as a standalone rating 

when there were no DBI sections that were applicable or in rare cases when a severe injury results 

in passive ROM loss qualifying for class 3 or 4 impairment or for amputation ratings. He explained 

that because the A.M.A., Guides did contain an appropriate DBI for appellant’s diagnosed 

condition, it did not meet any of the criteria of section 16.7, page 543, of the A.M.A., Guides to 

allow for impairment to be calculated under the ROM method. The DMA determined that the date 

of MMI was February 7, 2019.

On August 20, 2019 Dr. Mrochek disagreed with the DMA’s impairment rating. He stated

that the DMA had incorrectly interpreted the sixth edition A.M.A., Guides, as the permanent 

impairment rating was to be made based on the greater of the impairment ratings obtained by the 

DBI method or the ROM method. 

OWCP determined that a conflict of medical opinion existed between Dr. Mrochek and

Dr. Harris, the DMA, regarding the extent of appellant’s left lower extremity impairment. It 

referred appellant to Dr. James F. Hood, a Board-certified orthopedic surgeon, for an impartial 

medical examination. 

In a report dated October 23, 2019, Dr. Hood, an impartial medical examiner (IME),

reviewed appellant’s history regarding the August 2, 2018 employment injury and subsequent 

October 1, 2018 left knee surgery. On physical examination of appellant’s left lower extremity, 

he found that appellant lacked five degrees of full active extension with no flexion contracture and 

flexion to 115 degrees. Dr. Hood observed healed arthroscopic portals, tenderness over the 

patellofemoral area with discomfort on patellofemoral compression with minimal medial or lateral 

joint line tenderness. He noted that the knee was stable with negative Lachman and anterior drawer 

tests. Medial and lateral stability was normal. Dr. Hood further noted that a magnetic resonance 

imaging scan on September 19, 2018 indicated with reference to the medial meniscus, a posterior 

root ligament with a striated appearance and predominant femoral and tibial surface linear 

hyperintensity at the outer half of the posterior horn with mucoid degeneration. It also 

demonstrated, with regard to appellant’s patellofemoral area, that there was a lateral patellar cluster 

of high-grade chondral fissures, a central trochlear probable full-thickness chondral fissure, a 

medial low-grade femoral weight-bearing chondral fissure, effusion, and large, multiple chondral 

and ossific loose bodies. Dr. Hood concurred that appellant reached MMI on February 7, 2019

noting that at that time appellant had full ROM of the knee. He also explained that any limitation 

of motion would have been secondary to the preexisting and nonaggravated findings of 

patellofemoral chondromalacia as well as medial compartment arthritis and therefore not part of 

any impairment secondary to the work injury. Referring to the sixth edition A.M.A., Guides,

Dr. Hood noted that Table 16-3 for the CDX of partial lateral meniscectomy indicated a class 1 

with a default impairment of two percent of the left lower extremity. Referring to Table 16-7, the 

GMPE would be 2 for moderate findings on physical examination. The GMFH would be 1 for a 

mild functional lower limb study. The GMCS under Table 16-8 would be 2 for moderate findings. 

Applying the net adjustment formula, Dr. Hood found that appellant had three percent permanent 

impairment of the left lower extremity. 
4

By decision dated February 28, 2020, OWCP granted appellant a schedule award for three

percent permanent impairment of the left lower extremity. The award ran for 8.64 weeks from 

February 7 to April 8, 2019. OWCP noted that the schedule award was based on the October 23, 

2019 impartial medical opinion of Dr. Hood.

LEGAL PRECEDENT

The schedule award provisions of FECA3and its implementing regulations4set 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 to 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 through its implementing regulations, OWCP has adopted the A.M.A., Guides as the 

appropriate standard for evaluating schedule losses.5 As of May 1, 2009, schedule awards are 

determined in accordance with the sixth edition of the A.M.A., Guides (2009).6 The Board has 

approved the use by OWCP of the A.M.A., Guides for the purpose of determining the percentage 

loss of use of a member of the body for schedule award purposes.7

In determining permanent impairment of the lower extremities under the sixth edition of 

the A.M.A., Guides, an evaluator must establish the appropriate diagnosis for each part of the 

lower extremity to be rated. With respect to the knee, the relevant portion of the leg for the present 

case, reference is made to Table 16-3 (Knee Regional Grid) beginning on page 509.8 After the 

CDX is determined from the Knee Regional Grid (including identification of a default grade 

value), the net adjustment formula is applied using GMFH, GMPE, and GMCS. The net 

adjustment formula is (GMFH - CDX) + (GMPE - CDX) + (GMCS - CDX).9 Under Chapter 2.3, 

the evaluators are directed to provide reasons for their impairment rating choices, including the 

choices of diagnoses from regional grids and calculations of modifier scores.10

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

examination for the United States and the physician of the employee, the Secretary shall appoint a 

 

3 5 U.S.C. § 8107.

third physician who shall make an examination.11 When there are opposing reports of virtually 

equal weight and rationale, the case must be referred to an IME, pursuant to section 8123(a) of 

FECA, to resolve the conflict in the medical evidence.12 Where a case is referred to an IME for 

the purpose of resolving a conflict, the opinion of such specialist, if sufficiently well rationalized 

and based on a proper factual and medical background must be given special weight.13

ANALYSIS

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

three percent permanent impairment of the left lower extremity, for which he previously received 

a schedule award.

OWCP accepted that appellant sustained a peripheral tear of the medial meniscus of the 

left knee. Appellant underwent an OWCP-authorized left knee arthroscopic partial lateral 

meniscectomy and loose body removal on October 1, 2018.

OWCP properly determined that a conflict in the medical opinion evidence existed between

Dr. Mrochek, a treating physician, and Dr. Harris, an OWCP DMA, regarding the extent of 

appellant’s permanent impairment of the left lower extremity due to appellant’s accepted 

work-related condition. Dr. Mrochek had opined that the nature of appellant’s left leg permanent 

impairment allowed a rating under the sixth edition of the A.M.A., Guides utilizing the ROM 

method as the DBI method did not allow a rating for appellant’s full functional loss, while the 

DMA opined that the appellant’s permanent impairment was not an exceptional circumstance 

which allowed rating under the ROM method, pursuant to the guidelines provided in section 16-7, 

page 543 of the A.M.A., Guides. 

Dr. Hood was selected as the IME to resolve the conflict in medical opinion, pursuant to 

5 U.S.C. § 8123(a). In his October 23, 2019 report, he reviewed appellant’s history regarding the 

August 2, 2018 employment injury and appellant’s October 1, 2018 left knee surgery. On physical 

examination of appellant’s knee, Dr. Hood found five degrees lack of full active extension with no 

flexion contracture and flexion to 115 degrees. He concurred that appellant reached MMI on 

February 7, 2019. Dr. Hood properly applied the DBI methodology for rating appellant’s 

permanent impairment of the left lower extremity, as the ROM methodology was not applicable

given the accepted diagnosis and appellant’s examination findings.

14

 He noted that appellant’s 

loss of ROM was not due to his accepted left knee condition, but rather was due to preexisting and 

nonaggravated findings of patellofemoral chondromalacia as well as medial compartment arthritis, 

and therefore was not part of any impairment secondary to the work injury. Referring to the sixth 

edition A.M.A., Guides, Dr. Hood properly noted that Table 16-3 for the CDX of partial lateral 

meniscectomy indicated class 1 with a default impairment of two percent of the left lower 

extremity. Referring to Table 16-7, he properly found that the GMPE would be 2 for moderate

findings on physical examination, incorporating appellant’s loss of ROM as a factor in this 

assessment. Dr. Hood properly calculated that the GMFH would be 1 for a mild functional lower 

limb study. He properly found that the GMCS under Table 16-8 would be 2 for moderate findings. 

Applying the net adjustment formula, Dr. Hood properly calculated that appellant had three

percent permanent impairment of the left lower extremity. 

The Board finds that Dr. Hood’s impartial medical opinion is sufficiently well rationalized, 

having properly applied the appropriate standards of the A.M.A., Guides, and based upon a proper 

factual and medical background such that it is entitled to special weight.15 The evidence of record 

therefore establishes that appellant has three percent permanent impairment of the left lower 

extremity. 

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 his burden of proof to establish greater than 

three percent permanent impairment of the left lower extremity, for which he previously received 

a schedule award.
