After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed.R.App.P. 34(a); 10th Cir.R. 34.1.9. The case is therefore ordered submitted without oral argument.
Mr. Robert J. Pacheco appeals the district court’s order affirming the decision of the Secretary of Health and Human Services to terminate his Social Security disability insurance benefits. He argues that the district court should have remanded the action to the Secretary for a new hearing.
This court reviews the Secretary’s decision to determine whether the findings are supported by substantial evidence and whether the Secretary applied correct legal standards.
Bernal v. Bowen,
I.
Mr. Pacheco was found eligible for disability benefits on April 1, 1986. The Secretary found that Mr. Pacheco suffered from arthritis and a disabling back ailment *697 due to a work-related accident on February 18, 1981, and was entitled to disability benefits beginning June 1984. On February 16,1989, an administrative law judge determined after an administrative hearing that Mr. Pacheco’s condition had medically improved and that he became able to perform the full range of light work beginning January 1988. Based on this conclusion, the administrative law judge entered an order finding that Mr. Pacheco was not disabled. After the completion of the administrative proceedings, Mr. Pacheco submitted an additional medical evaluation by Dr. Barry Hillmer, M.D., dated October 2, 1989. The Appeals Council found that this report supported the administrative law judge’s findings and therefore denied Mr. Pacheco’s application for review on July 25, 1989. The Secretary’s decision was subsequently upheld by the district court.
Mr. Pacheco takes exception with only the last stage of the evaluation process, where the Secretary found that he can perform other work in the national economy. See 20 C.F.R. §§ 404.1594, 416.920. He complains that the Secretary’s conclusion is not supported by substantial evidence.
Substantial evidence is such evidence that a reasonable mind might accept as adequate to support the conclusion reached by the Secretary.
Richardson v. Perales,
II.
Mr. Pacheco differs with the Secretary’s finding that he could perform light work. The dispute centers on the following statement by Dr. Hillmer, a physician who examined Mr. Pacheco on October 2, 1989:
This man has enough problems, with particularly his knee and his low back, that I do not think he can successfully do heavy work. Theoretically he could do light work, but with his ninth grade education, the practical possibilities for this are unlikely. At this point, before he can do anything, he needs to have the torn portion of the medial meniscus of the right knee removed and then be put on a strengthening program.
App. at 96. Dr. Hillmer’s evaluation was performed subsequent to the hearing before the administrative law judge and the results were submitted to the Appeals Council only. In its letter to Mr. Pacheco dated October 2, 1989, the Appeals Council relied on Dr. Hillmer’s conclusion, along with other evidence of record, to find that Mr. Pacheco possesses the functional capacity to perform light work activity.
Mr. Pacheco emphasizes here Dr. Hill-mer’s belief that knee surgery is required before Mr. Pacheco could perform any work. He complains that until surgery is performed and his knee is rehabilitated, he is still disabled. Citing section 404.1530(a) of the Secretary’s regulations, the Secretary responds that an impairment that can reasonably be remedied by treatment is not disabling. * 20 C.F.R. § 404.1530(a) (1990); see also 20 C.F.R. 416.930(a) (1990).
The regulation to which the Secretary refers requires that a recipient follow prescribed treatment if the treatment can restore his or her ability to work or benefits will cease. 20 C.F.R. §§ 404.-1530(b), 416.930(b) (1990). In previous cases, this court has set out four requirements that must be met before a claimant’s failure to undertake treatment will preclude the recovery of disability benefits: “(1) the treatment at issue should be ex
*698
pected to restore the claimant’s ability to work; (2) the treatment must have been prescribed; (3) the treatment must have been refused; (4) the refusal must have been without justifiable excuse.”
Teter v. Heckler,
The Secretary did not make a finding that Mr. Pacheco refused to follow the prescribed treatment. Nor did he find that there was no justifiable excuse for Mr. Pacheco to refuse the prescribed treatment. Because the Secretary did not apply the correct legal standards, we find the Secretary’s reliance on Dr. Hillmer’s diagnosis to find Mr. Pacheco not disabled improper. We remand this case with instructions to reinstate Mr. Pacheco’s disability benefits, including retroactive payments, until the Secretary conducts a further hearing following the steps set forth by this court in
Teter
and, if merited, issues a valid order terminating Mr. Pacheco’s benefits.
See White v. Heckler,
In remanding the ease to the Secretary for a further evidentiary hearing, we do not mean to preclude the Secretary from acting in his proper role as factfinder. The Secretary may discount the report of Dr. Hillmer when faced with the remainder of the evidence in the record. It is clear here, however, that Dr. Hillmer’s report was credited, and relied upon, to find Mr. Pacheco disabled. As we have already articulated, we do not believe that Dr. Hillmer’s diagnosis supports such a finding without a further hearing to determine whether Mr. Pacheco unjustifiably refused the prescribed treatment.
III.
Mr. Pacheco also challenges the administrative law judge’s determination that he does not suffer a mental impairment that would significantly reduce his functional capacity for the full range of light work. Mr. Pacheco therefore takes exception with the administrative law judge’s use of Appendix 2 as a framework for his decision that Mr. Pacheco could perform work in the national economy beginning January 1988. In light of our remand to determine whether Mr. Pacheco improperly refused medical treatment, we need not reach this issue.
For the foregoing reasons, the judgment of the district court is REVERSED. The cause is REMANDED to the district court for further proceedings consistent with this opinion. The mandate shall issue forthwith.
Notes
The genesis of this proposition in case law stems from a previous regulation which no longer exists. That provision provided:
An individual will be deemed not under a disability if, with reasonable effort and safety to himself, the impairment can be diminished to the extent that the individual will not be prevented by the impairment from engaging in any substantial gainful activity.
