|LESA F. MORRIS,
Plaintiff - Appellant,
JO ANNE B. BARNHART, Commissioner of Social Security Administration,
Defendant - Appellee.
We exercise jurisdiction over this appeal pursuant to 28 U.S.C. § 1291 and 42 U.S.C. § 405(g). Our review, however, is limited to evaluating whether the factual findings are supported by substantial evidence and whether the correct legal standards were applied. Goatcher v. United States Dep't of Health & Human Servs., 52 F.3d 288, 289 (10th Cir. 1995). Morris challenges the ALJ's denial of benefits for the period after 1994 on two grounds. First, she contends that the ALJ failed to consider her alleged impairments in combination, as required by applicable law. See Hargis v. Sullivan, 945 F.2d 1482, 1491 (10th Cir. 1991) (citing 42 U.S.C. § 423(d)(2)(C)). Second, she argues that the ALJ failed properly to assess the credibility of her testimony at the hearing.
In support of these claims, however, Morris essentially contends that the medical record shows that her alleged impairments were more serious or severe than determined by the ALJ. We may not reweigh the evidence or substitute our judgment for that of the agency. Casias v. Sec'y of Health & Human Servs., 933 F.2d 799, 800 (10th Cir. 1991). Further, the record does not support Morris' assertions that the ALJ failed to view her alleged impairments in combination or improperly assessed her credibility. More importantly, Morris does not argue or demonstrate that the ALJ erred in his determination of her residual functional capacity or in his ultimate conclusion that she could perform her past relevant work. Claimant bears the burden at step four to show that she is unable to return to her past jobs or occupations. See Andrade v. Sec'y of Health & Human Servs., 985 F.2d 1045, 1051 (10th Cir. 1993). Because we conclude, based on our careful review of the record, that substantial evidence in the record supports the ALJ's ultimate determinations as to Morris' RFC and her resulting ability to work, we must affirm the agency's denial of benefits. Accordingly, the judgment of the district court is AFFIRMED.
