MEMORANDUM OPINION AND ORDER OF REMAND
On June 3, 2010, plaintiff Olivia Maria Villarreal ("plaintiff") filed a Complaint seeking review of the Commissioner of Social Security's denial of plaintiff's application for benefits. The parties have consented to proceed before a United States Magistrate Judge.
This matter is before the Court on the parties' cross motions for summary judgment, respectively ("Plaintiff's Motion") and ("Defendant's Motion"). The Court has taken both motions under submission without oral argument. See Fed. R. Civ. P. 78; L.R. 7-15; June 8, 2010 Case Management Order, ¶ 5.
Based on the record as a whole and the applicable law, the decision of the Commissioner is REVERSED AND REMANDED for further proceedings consistent with this Memorandum Opinion and Order of Remand.
II. BACKGROUND AND SUMMARY OF ADMINISTRATIVE DECISION
On May 30,2006, plaintiff filed an application for Disability Insurance Benefits. (Administrative Record ("AR") 10, 82). Plaintiff asserted that she became disabled on January 31, 1999, due to lupus, diabetes, back problems, pain throughout her body, and knee problems. (AR 103). The Administrative Law Judge ("ALJ") examined the medical record and heard testimony from plaintiff (who was represented by counsel) and a vocational expert on January 31, 2008. (AR 16).
On April 18, 2008, the ALJ determined that plaintiff was not disabled through the date last insured (i.e., December 31, 2003). (AR 15). Specifically, the ALJ found: (1) plaintiff suffered from the following severe impairments: fibromyalgia and polymyalgia rheumatica (AR 12); (2) plaintiff's impairments, considered singly or in combination, did not meet or medically equal one of the listed impairments (AR 12); (3) plaintiff retained the residual functional capacity to perform the full range of medium work (20 C.F.R. § 404.1567(c)) (AR 13); (4) plaintiff could perform her past relevant work (AR 15); and (5) plaintiff's allegations regarding her limitations were not credible to the extent they were inconsistent with the ALJ's residual functional capacity assessment (AR 14).
The Appeals Council denied plaintiff's application for review. (AR 1).
III. APPLICABLE LEGAL STANDARDS
A. Sequential Evaluation Process
To qualify for disability benefits, a claimant must show that she is unable to engage in any substantial gainful activity by reason of a medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of at least twelve months. Burch v. Barnhart, 400 F.3d 676, 679 (9th Cir. 2005) (citing 42 U.S.C. § 423(d)(1)(A)). The impairment must render the claimant incapable of performing the work she previously performed and incapable of performing any other substantial gainful employment that exists in the national economy. Tackett v. Apfel, 180 F.3d 1094, 1098 (9th Cir. 1999) (citing 42 U.S.C. § 423(d)(2)(A)). In assessing whether a claimant is disabled, an ALJ is to follow a five-step sequential evaluation process:
(1) Is the claimant presently engaged in substantial gainful activity? If so, the claimant is not disabled. If not, proceed to step two.
(2) Is the claimant's alleged impairment sufficiently severe to limit her ability to work? If not, the claimant is not ...
