MEMORANDUM OPINION AND ORDER AFFIRMING DECISION OF THE COMMISSIONER OF SOCIAL SECURITY PROCEEDINGS
On August 14, 2012, Ray Straw ("Plaintiff" or "Claimant") filed a complaint seeking review of the decision by the Commissioner of Social Security ("Commissioner") denying Plaintiff's applications for Social Security Disability Insurance benefits and Supplemental Security Income benefits. The Commissioner filed an Answer on November 15, 2012. On February 13, 2013, the parties filed a Joint Stipulation ("JS"). The matter is now ready for decision.
Pursuant to 28 U.S.C. § 636(c), both parties consented to proceed before this Magistrate Judge. After reviewing the pleadings, transcripts, and administrative record ("AR"), the Court concludes that the Commissioner's decision must be affirmed and this case dismissed with prejudice.
Plaintiff is a 47 year old male who applied for Social Security Disability Insurance benefits and Supplemental Security Income benefits on July 14, 2006. (AR 8.) The ALJ determined that Plaintiff has not engaged in substantial gainful activity since April 2, 2002, the alleged onset date of his disability. (AR 10.)
Plaintiff's claims were denied initially on September 14, 2006, and on reconsideration on February 16, 2007. (AR 8.) Plaintiff filed a timely request for hearing, which was held before Administrative Law Judge ("ALJ") F. Keith Varni on March 28, 2008, in San Bernardino, California. (AR 8.) The ALJ issued an unfavorable decision on August 19, 2008. (AR 8-13.) The Appeals Council denied review on January 16, 2009. (AR 1-3.)
Litigation ensued in this Court with a complaint filed by Plaintiff on March 16, 2009 (Civil Docket # 5:09-CV-00511-JEM), and on June 8, 2010, this Court reversed the 2008 hearing decision and remanded the case for further proceedings with regard to credibility, developing the record, and considering all impairments in combination. (AR 351-62.) The Appeals Council remanded the case for further proceedings consistent with this Court's decision on August 28, 2010. (AR 347-50.)
ALJ Tamara Turner-Jones conducted a second hearing on March 2, 2011. (AR 364-426.) She subsequently granted a partially favorable decision on March 22, 2011. (AR 455-69.) She granted benefits for a closed period, from February 6, 2003, through February 7, 2008, but denied benefits thereafter. (AR 464-5.)
As reflected in the Joint Stipulation, Plaintiff raises the following disputed issues as grounds for reversal and remand:
1. Whether the ALJ properly assessed Plaintiff's credibility.
2. Whether the ALJ properly considered Plaintiff's residual functional capacity ("RFC").
3. Whether the ALJ properly developed the record.
4. Whether the ALJ properly considered the February 2010 treating source statement at AR 601.
5. Whether the ALJ properly considered Plaintiff's severe impairment at Step 2.
Under 42 U.S.C. § 405(g), this Court reviews the ALJ's decision to determine whether the ALJ's findings are supported by substantial evidence and free of legal error. Smolen v. Chater, 80 F.3d 1273, 1279 (9th Cir. 1996); see also DeLorme v. Sullivan, 924 F.2d 841, 846 (9th Cir. 1991) (ALJ's disability determination must be supported by substantial evidence and based on the proper legal standards).
Substantial evidence means "'more than a mere scintilla,' but less than a preponderance." Saelee v. Chater, 94 F.3d 520, 521-22 (9th Cir. 1996) (quoting Richardson v. Perales, 402 U.S. 389, 401 (1971)). Substantial evidence is "such relevant evidence as a reasonable mind might accept as adequate to support a conclusion." Richardson, 402 U.S. at 401 (internal quotation marks and citation omitted).
This Court must review the record as a whole and consider adverse as well as supporting evidence. Robbins v. Soc. Sec. Admin., 466 F.3d 880, 882 (9th Cir. 2006). Where evidence is susceptible to more than one rational interpretation, the ALJ's decision must be upheld. Morgan v. Comm'r of the Soc. Sec. Admin., 169 F.3d 595, 599 (9th Cir. 1999). "However, a reviewing court must consider the entire record as a whole and may not affirm simply by isolating a 'specific quantum of supporting evidence.'" Robbins, 466 F.3d at 882 (quoting Hammock v. Bowen, 879 F.2d 498, 501 (9th Cir. 1989)); see also Orn v. Astrue, 495 F.3d 625, 630 (9th Cir. 2007).
THE SEQUENTIAL EVALUATION
The Social Security Act defines disability as the "inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or . . . can be expected to last for a continuous period of not less than 12 months." 42 U.S.C. §§ 423(d)(1)(A), 1382c(a)(3)(A). The Commissioner has established a five-step sequential process to determine whether a claimant is disabled. 20 C.F.R. §§ 404.1520, 416.920.
The first step is to determine whether the claimant is presently engaging in substantial gainful activity. Parra v. Astrue, 481 F.3d 742, 746 (9th Cir. 2007). If the claimant is engaging in substantial gainful activity, disability benefits will be denied. Bowen v. Yuckert, 482 U.S. 137, 140 (1987). Second, the ALJ must determine whether the claimant has a severe impairment or combination of impairments. Parra, 481 F.3d at 746. An impairment is not severe if it does not significantly limit the claimant's ability to work. Smolen v. Chater, 80 F.3d 1273, 1290 (9th Cir. 1996). Third, the ALJ must determine whether the impairment is listed, or equivalent to an impairment listed, in 20 C.F.R. Pt. 404, Subpt. P, Appendix I of the regulations. Parra, 481 F.3d at 746. If the impairment meets or equals one of the listed impairments, the claimant is presumptively disabled. Bowen v. Yuckert, 482 U.S. at 141. Fourth, the ALJ must determine whether the impairment prevents the claimant from doing past relevant work. Pinto v. Massanari, 249 F.3d 840, 844-45 (9th Cir. 2001).
Before making the step four determination, the ALJ first must determine the claimant's residual functional capacity ("RFC"). 20 C.F.R. § 416.920(e). Residual functional capacity ("RFC") is "the most [one] can still do despite [his or her] limitations" and represents an assessment "based on all the relevant evidence." 20 C.F.R. §§ 404.1545(a)(1), 416.945(a)(1). The RFC must consider all of the claimant's impairments, including those that are not severe.
20 C.F.R. §§ 416.920(e), 416.945(a)(2); Social Security Ruling ("SSR") 96-8p.
If the claimant cannot perform his or her past relevant work or has no past relevant work, the ALJ proceeds to the fifth step and must determine whether the impairment prevents the claimant from performing any other substantial gainful activity. Moore v. Apfel, 216 F.3d 864, 869 (9th Cir. 2000). The claimant bears the burden of proving steps one through four, consistent with the general rule that at all times the burden is on the claimant to establish his or her entitlement to benefits. Parra, 481 F.3d at 746. Once this prima facie case is established by the claimant, the burden shifts to the Commissioner to show that the claimant may perform other gainful activity. Lounsburry v. Barnhart, 468 F.3d 1111, 1114 (9th Cir. 2006). To support a finding that a claimant is not disabled at step five, the Commissioner must provide evidence demonstrating that other work exists in significant numbers in the ...
