Opinion for the Court filed by Circuit Judge SENTELLE.
The George Hyman Construction Company (“Hyman” or the “Company”) seeks reversal of a Benefits Review Board (the “Board”) award of $13,455.84 in attorney fees in connection with Mr. James E. Brooks’s claim under the Longshore and Harbor Workers’ Compensation Act, 33 U.S.C. §§ 901-950 (1986) (the “Act”), as applied to the District of Columbia, 36 D.C.Code §§ 501, 502 (1973).
1
Hyman argues that reversal is necessary because the Board failed to appreciate the teachings of the Supreme Court in
Hensley v. Eckerhart,
I.
This case stems from an accident at a construction site over a decade ago. May 7, 1981 found Respondent Brooks, a Hy-man employee, stripping plywood from a ceiling when a board fell on his large left toe. In subsequent workers’ compensation hearings, Brooks advanced two theories as to why the toe injury rendered him totally and permanently incapable of returning to work and, thus, deserving of full compensation under § 908(a) of the Act. Under the first, Brooks claimed that the toe injury triggered a psychiatric illness apparently known as “conversion reaction hysteria.” Under the second, he asserted that the toe injury caused recurring pain and numbness in his leg, hip, and back.
The AU rejected both of Brooks’s total disability theories. Nonetheless, and on his own motion, the AU found Brooks deserving of a twenty percent permanent partial disability rating for his damaged left foot pursuant to § 908(c) of the Act; he subsequently awarded Brooks $11,968.73. We note that the Company had previously vol *1535 untarily paid Brooks compensation for a ten percent disability rating of the injured toe.
Merits decided, the AU turned to the question of whether Brooks ought to recoup his attorney fees and costs from Hy-man. As is perhaps typical of our times, it is here that the real dispute began. The AU was presented with a bill from Brooks totalling approximately $24,000, roughly twice the size of actual benefits received by claimant. Hyman argued that fee recoveries under the Act should be limited to work done on successful claims; further, it contended that since claimant’s counsel spent approximately one hundred percent of their time on the unsuccessful total disability claims, and it was the AU who raised the only successful issue, no fees should be awarded.
The AU rejected Hyman’s argument, concluding instead that the §§ 908(a) and (c) claims were too “interrelated” to separate out in a claim-by-claim analysis such as Hyman suggested. The AU also dismissed a further Hyman suggestion that any award should be reduced to reflect the degree of success Brooks achieved in pursuing his claims. He stated that the “test for determining whether services are com-pensable is [not success, but] whether the attorney, at the time he performed the services, reasonably regarded the work as necessary to establish claimant’s entitlement to benefits.” Supplemental Decision and Order Awarding Attorney’s Fees by Administrative Law Judge Frank F. Marcellino, Oct. 24, 1985, at 2-3 (citation omitted) (the “ALJ Fee Order”).
Appeals to the Board were taken by both parties. Brooks challenged the disposition of his § 908(a) total and permanent disability claims, while Hyman sought reversal of the fee award. The Board affirmed the AU’s opinion in all respects. Claimant has now dropped his total, permanent disability claims and, consequently, the only issues before us revolve around the fee award.
II.
A.
In Hensley v. Eckerhart, the Supreme Court defined the conditions under which a plaintiff who prevails on only some of his claims may recover attorney fees under the Civil Rights Attorney's Fees Awards Act of 1976, 42 U.S.C. § 1988. Specifically, it provided for a two-step inquiry focused on the following questions:
First, did the plaintiff fail to prevail on claims that were unrelated to the claims on which he succeeded? Second, did the plaintiff achieve a level of success that makes the hours reasonably expended a satisfactory basis for making a fee award?
See Sierra Club v. EPA,
Under the second
Hensley
inquiry, the factfinder must then consider whether the success obtained on the remaining claims is proportional to the efforts expended by counsel. When an injured party obtains “excellent results, his attorney should recover a fully compensatory fee.”
Though the
Hensley
analysis was crafted in the § 1988 context, it was explicitly designed by the Court to apply to all federal statutes limiting fee awards to “ ‘prevailing partpes].’ ”
See id.,
at 433 n.

B.
The first issue now before us is whether the Hensley rationale applies to the Act as well. We hold that it does, and come to our conclusion impressed by the language and history of the Act and influenced by the authority of others who have reached this question before us. The Act provides in pertinent part that
if the compensation ... awarded [by the Board] is greater than the amount paid or tendered by the employer or carrier, a reasonable attorney’s fee based solely upon the difference between the amount awarded and the amount tendered or paid shall be awarded....
33 U.S.C. § 928(b). 2
To be sure the Act does not, as claimant emphasizes, use the term “prevailing party” anywhere in § 928(b). However, it is a vain project to rely, as claimant does, on the absence of this particular verbiage to prove Hensley’s irrelevance. The thrust of the Hensley opinion is devoted not to the use of the words “prevailing party,” but to the concept encompassed within those words. This Circuit has already held that the Hensley rationale applies to statutes not containing the “prevailing party” formulation, but requiring a degree of success as requisite to the award of counsel fees.
In
Sierra Club,
The present case is stronger for the application of Hensley than was Sierra Club. The Act before us requires on its face a showing of success on the merits before any fee becomes appropriate. By its terms, the attorney fees provision is triggered only “if the compensation ... awarded ... is greater than the amount paid or tendered by the employer or carrier.” 33 U.S.C. § 928(b). Even when triggered, the statute provides only a fee “based solely upon the difference between the amount awarded and the amount tendered or paid.” Id. This language differs less from the wording of the statute before the Hensley Court than did the language before our Sierra Club Court, and the concept differs in no determinative way.
Respondent argues that the language of the Act defining fee recovery as “based solely upon the difference between the amount tendered and the amount awarded” precludes an initial step-by-step analysis of success. In fact, the Board so held in Columbus Cherry v. Newport News Shipbuilding and Drydock Co., 8 BRBS 857 (1978). There the Board honored attorney fee claims for services attributable to issues on which claimant lost, reasoning that *1537 “[a]ll of counsel’s services can be considered for a fee award, as long as he succeeded in increasing ... compensation.” Id. at 864.
We reject both respondent’s suggestions and the Board’s holding in Cherry. 3 The Act’s use of the word “solely” does not preclude an issue-by-issue examination of success but, rather, suggests that once success on an issue is demonstrated, recovery is limited “solely” to work done to increase compensation on that particular issue. This view of the Act is confirmed by the legislative history. See H.R.Rep. No. 1441, 92d Cong., 2d Sess. 9, 20, reprinted in 1972 U.S.C.C.A.N. 4698, 4706, 4717. As explained by a Report by the House Committee on Education and Labor (the “House Report”), the Act’s fee provision
authorize^] assessment of legal fees against employers in cases where the existence or extent of liability is controverted and the claimant succeeds in establishing liability or obtaining increased compensation in formal proceedings or appeals. Attorneys fees may only be awarded against the employer where the claimant succeeds, and the fees awarded are to be based on the amount by which the compensation payable is increased as a result of litigation.
Id. at 9, reprinted in 1972 U.S.C.C.A.N. 4706.
Respondent argues that reading the Act in this fashion will work an injustice. Specifically, he contends that application of Hensley, in conjunction with an apparent regulatory prohibition against fee contracts and fee recovery if benefits are not obtained, 4 will leave claimant’s counsel “run[ning] a substantial risk of not being paid at all.” Respondent’s Brief at 7 n. 3. We find this appeal to policy arguments unavailing, however, in light of Congress’s declaration of its own policy intentions.
Significantly, we are not the first court to reach the question of Hensley’s applicability to the Act. The First Circuit has already faced this issue and resolved it much as we do today.
General Dynamics Corp. v. Horrigan,
In sum, we find that the Act’s substantive language demands application of Hensley ’s two-step inquiry. In doing so, we act in consonance with Sierra Club, the legislative history of the Act, and the First Circuit’s decision on the matter.
III.
Given Hensley’s relevance, we next turn to consider the ALJ’s handling of its first inquiry. In conducting this analysis, again, the factfinder is obliged to prevent claimant from “piggybacking” fees incurred for work done on losing claims onto unrelated winning issues.
See Sierra Club,
*1538 A.
In the instant case, Hyman argued that the unsuccessful § 908(a) total disability claims on which claimant failed were unrelated to the § 908(c) partial disability claims on which he did succeed. Consequently, the Company contended, Brooks was entitled to no fee recovery for work done on the losing § 908(a) claims.
The ALJ rejected Hyman’s argument, finding instead that all claims in this case were interrelated. In doing so, however, the AU provided little explanation for his result. In fact, he merely cited the now-rejected Cherry decision for the proposition that counsel should recoup fees accrued on all issues if he succeeds on any issue; noted that Hensley permits such a result when issues are interrelated; and then bluntly stated, without more, that the issues in this case are interrelated.
While we are mindful of the special deference owed factfinders in the award of attorney fees,
see Hensley,
Thus, we turn to the Board’s decision on review. Rather than focusing on the particulars of this case, however, the Board seemed to suggest that an interrelatedness finding was justified here as a matter of law because of its findings in a pair of prior cases: Battle v. A.J. Ellis Construction Company, 16 BRBS 329 (1984) and Stowars. Rather than curing the defects in the AU’s opinion, however, the Board’s heavy reliance on these cases merely exacerbates them.
Cherry, decided in a pre-Hensley environment, again stated that claimant’s counsel was entitled to recover fees for work done on all issues after winning on only one. Battle and Stowars, coming after Hensley, were merely attempts to save Cherry’s rule of complete recovery despite Hensleys contrary suggestions. They did so by asserting that “[i]n most cases [under the Act], the issues are too inter-related to permit allocation of the fee between successful and unsuccessful issues.” Battle, 16 BRBS at 331. Simply put, they explained that complete recovery under Cherry was justified in a post-Hensley world because nearly everything under the Act is interrelated.
Battle
and
Stowars
’ presumption of interrelatedness cannot support its own weight, let alone that of the case before us. First, it runs contrary to Congress’s suggestions that courts can and should distinguish between those issues on which claimant succeeds and fails.
See
House Report,
supra.
Second, it does not merely reconcile or explain
Hensley
as the Board seems to suggest; rather it eviscerates
Hensley
by ignoring the Court’s statement that most fee award issues “essentially are factual matters,”
In sum, we reject the interrelatedness presumption, as there may indeed be occasions when claims under the Act are easily severable. At the same time, we do not ignore the possibility that many claims might be interrelated. Each case, with its separate facts and varying legal theories, however, deserves a separate look, as the different outcomes on similar claims in
Battle
and
Horrigan
suggest. We ask only what the Court in
Hensley
required: that the factfinder offer a brief, but clear, explanation of his reasons for concluding claims severable or interrelated in each case.
See
B.
To this point, we have concluded that neither the explanations given by the AU nor those proffered by the Board can pass muster on review. The AU’s failure to provide reasons is fatal under both Hensley and Chenery. His failure is not cured by the Board’s troublesome presumption that most cases under the Act are interrelated.
Ordinarily, we might at this point remand with instructions to the AU and Board to detail the reasons for their interrelatedness conclusion in this case. On occasion, however, we find that a remand would be futile on certain matters as only one disposition is possible as a matter of law. In such cases, we retain and decide the issue.
Chenery
and its progeny, while emphasizing the importance of agency explanations, do not “require that we convert judicial review of agency action into a ping-pong game.”
NLRB v. Wyman-Gordon Co.,
The question of interrelatedness in this case is one on which remand would indeed be futile: no rational factfinder conscientiously applying Hensley’s teachings could find the § 908(c) claim in this case to be interrelated with the § 908(a) claims. No matter how massaged, such a result would necessarily trench upon Hensley’s dictates.
The Supreme Court in
Hensley
instructed that claims are interrelated if they are based on the same facts or legal theories.
See
In the instant case, however, the total and partial disability claims are based on different factual theories. The facts needed to demonstrate total disability—whether due to psychiatric or physical causes—go well beyond the simple medical reports needed to establish a partially dysfunctional foot. And, indeed, the record is replete with expert medical testimony aimed at establishing these additional factors; still, only two bare medical reports regarding the- foot itself were apparently introduced—one of which the Company had already conceded was correct. 5
Likewise, the claims are based on different legal theories. This is evidenced by the fact that respondent apparently never pressed the potential § 908(c) claim in his brief to the AU or even in argument. 6 Respondent made a tactical decision to vie for complete recovery, to channel his resources and argument into one legal theory. It was left to the AU to acknowledge and adopt § 908(c) as a separate legal basis for recovery.
*1540
The differing prerequisites for recovery under §§ 908(a) and (c) reinforce our conclusion that the claims in this case are not interrelated. A total disability claim under § 908(a) “is an economic and not a medical concept” based on claimant’s loss of wage-earning capacity.
American Mutual Insurance Co. of Boston v. Jones,
In some cases it may prove well nigh impossible for any reasonable factfinder to divide the hours expended on a claim-by-claim basis, or “sever[ ] [counsel’s work on different issues] in any meaningful sense.”
Horrigan,
In sum, we conclude that the § 908(a) claims are unrelated to the § 908(c) claims and acknowledge, as all parties do, that they were unsuccessful. Consequently, we must find that no fee award based on work performed in their pursuit is appropriate.
IV.
Having reversed the ALJ and Board’s interrelatedness determination and their award of fees on the § 908(a) claims, one issue remains: what of the § 908(c) partial disability claim? It was successful and, thus, appears to survive the first
Hensley
inquiry. Under
Hensley,
any work done by respondent’s attorney in its pursuit is subject to limitation only based upon an examination of whether the level of success achieved makes the hours reasonably expended a satisfactory basis for making a fee award.
See
We return to the AU’s decision, again recognizing the deference due a factfinder’s initial judgment. In doing so, we find that the AU completely refused to conduct a second-step Hensley inquiry with regard to this claim:
Although some courts have held that attorney fees should be adjusted according to the degree of success obtained, ... [t]he Board’s test for determining whether services are compensable is whether the attorney, at the time he performed the services, reasonably regarded the work as necessary to establish claimant’s entitlement to benefits.
ALJ Fee Order, at 2-3 (citation omitted). Though the AU appeared at least to acknowledge the relevance of Hensley’s first step, he nonetheless dismissed the Supreme Court’s prescribed degree of success examination as nothing more than the suggestion of “some courts.” Interestingly, the Board did nothing to disabuse the AU of his apparent belief that he could ignore Hensley’s second step. Rather, it merely confirmed the AU’s erroneous assumption that an inquiry into whether the attorney himself reasonably thought the work he performed was necessary is somehow relevant to a Hensley analysis. It is not.
The AU and Board’s utter failure to conduct a second-step Hensley review on the § 908(c) claim cannot be countenanced. Thus, we remand for consideration of work done by respondent’s counsel on the § 908(c) claim alone in light of the degree of success achieved on this issue alone. In doing so, we recognize that the amount of work done by counsel on this claim may be nearly negligible: again, Hyman asserts, and respondent does not appear to contest, that respondent’s counsel worked exclusively on the § 908(a) claim. See supra n. 6. In fact, it may be that the only work counsel did on the § 908(c) issue was to provide the AU with Dr. Bruno’s medical report, see supra n. 5, from which the AU drew his own conclusions. However, this Court is not in a position to affix a specific *1541 dollar figure to such work and, thus, we return the matter to the Board. 7
CONCLUSION
We find Hensley applicable to the Act and in doing so reject Cherry. We reverse the AU and Board’s interrelatedness determination and the presumption embodied in Battle and Stowars. Consequently, we find no fee award due on the § 908(a) claims. As to the successful § 908(c) claim, we remand, instructing the Board to apply a second-step Hensley analysis and provide a clear and concise explanation of its reasons for any award.
It is so ordered.
