supplemental security income under Title XVI of the Social Security Act. We
review de novo, Ghanim v. Colvin, 763 F.3d 1154, 1159 (9th Cir. 2014), and we
affirm.
Perestoronina contends that she established that she was not able to perform
her past relevant work as a phlebotomist. We disagree. The ALJ erred in basing
the Step Four determination that Perestoronina was able to perform her past
relevant work as she actually performed it on the vocational expert’s erroneous
reliance on a description of Perestoronina’s past work that reflected demands that
exceeded the residual functional capacity (“RFC”) assessment’s limitation to
occasional stooping. See SSR 82-61, 1982 WL 31387 at *2 (explaining that, when
evaluating whether a claimant retains the ability to perform “the particular
functional demands and job duties peculiar to an individual job as he or she
actually performed it,” the claimant should be found to be not disabled if “the
evidence shows that a claimant retains the RFC to perform the functional demands
and job duties of a particular past relevant job as he or she actually performed it.”).
However, that error was harmless, because substantial evidence supports a
comparison of Perestoronina’s RFC with the demands of her past work, as she
actually performed it, to determine that Perestoronina was capable of performing
her past relevant work as a phlebotomist.

It is permissible for an ALJ to rely on a claimant’s descriptions of her past
work to “define” that past work as actually performed. Pinto v. Massanari, 249
F.3d 840, 845 (9th Cir. 2001). Having assessed Perestoronina’s statements about
her abilities as credible only to the extent that they were consistent with the
residual functional capacity (“RFC”) assessment, the ALJ permissibly inferred at
Step Four that Perestoronina was able to perform her past relevant work as a
phlebotomist as far as she had credibly described it. See Sprague v. Bowen, 812
F.2d 1226, 1230 (9th Cir. 1987) (“The general rule is that conflicts in the evidence
are to be resolved by the Secretary.”); Sample v. Schweiker, 694 F.2d 639, 642 (9th
Cir. 1982) (explaining that an ALJ may “draw inferences logically flowing from
the evidence”). Because substantial evidence supports the ALJ’s Step Four
determination, any error in relying on the vocational expert’s testimony is
harmless. See Molina v. Astrue, 674 F.3d 1104, 1115 (9th Cir. 2012) (“ALJ’s error
is harmless where it is inconsequential to the ultimate nondisability determination.”
(quotation marks and citations omitted)). As a result, Perestoronina has not met
her burden of establishing that the demands of her past work as actually performed
exceed the limitations adopted by the ALJ in her RFC assessment. See Pinto, 249
F.3d at 844 (“At step four, claimants have the burden of showing that they can no
longer perform their past relevant work.”).
