   MEMORANDUM

The administrative law judge (“ALJ”) gave specific, cogent reasons supported by substantial evidence for finding Barragan not credible, including her failure to document unsuccessful attempts to get treatment between 1994 and 1998, and her varying accounts of the origin of her injuries. See Lester v. Chater, 81 F.3d 821, 834 (9th Cir.1996). The ALJ’s rejeetion of Barragan’s claims of pain was also supported by substantial evidence, because the ALJ found that such claims were not supported by the available medical evidence. See Tidwell v. Apfel, 161 F.3d 599, 602 (9th Cir.1999).

The ALJ’s reliance on Dr. Knapp’s report was supported by substantial evidence because Barragan offered nothing to show it was fraudulent aside from her unsupported testimony and, as we have held, the ALJ permissibly found her not credible. Further, as Barragan did not argue that she had a right to cross examine Dr. Knapp before the district court, that argument has been waived. See Echazabal v. Chevron USA Inc., 336 F.3d 1023, 1035 (9th Cir.2003).

The ALJ’s decision to discount the opinions of Drs. Cohen and Flores was supported by substantial evidence. They were nontreating physicians and their reports lacked objective clinical findings, relied largely on Barragan’s subjective complaints, and conflicted with those of treating physicians Drs. Weider, Slater, and Heikali. See Lester, 81 F.3d at 830.

The reports of Drs. Weider, Slater, Heikali, Knapp and Mahfoozi provide substantial evidence for the ALJ’s findings that Barragan’s impairments did not meet or equal a Listing. Further, the ALJ properly accounted for the fact that some of these reports were provided as part of a workers’ compensation claim, see Desrosiers v. Sec’y of Health & Human Servs., 846 F.2d 573, 576 (9th Cir.1988). Finally, the ALJ’s finding that Barragan retained the residual functional capacity to perform past relevant work was supported by substantial evidence, including vocational-expert testimony.

AFFIRMED.
