MEMORANDUM OPINION AND ORDER
Plaintiff, who is proceeding with retained counsel, brings this action under 42 U.S.C. § 405(g) for judicial review of a final decision of the Commissioner of Social Security. Pursuant to the written consent of all parties, this case is before the undersigned as the presiding judge for all purposes, including entry of final judgment. See 28 U.S.C. § 636(c). Pending before the court are plaintiff's motion for summary judgment (Doc. 15) and defendant's cross-motion for summary judgment (Doc. 16).
Plaintiff applied for social security benefits on December 19, 2008. In the application, plaintiff claims that disability began on October 18, 2002. Plaintiff claims that disability is caused by a combination of: "Rt. shoulder and lower back pain, spastic colon, chronic daily pain and limited ROM in the right shoulder and lower back." Plaintiff's claim was initially denied. Following denial of reconsideration, plaintiff requested an administrative hearing, which was held on March 30, 2010, before Administrative Law Judge ("ALJ") John R. Price. In a April 19, 2010, decision, the ALJ concluded that plaintiff is not disabled based on the following relevant findings:
1. The claimant has the following severe impairment(s): right rotator cuff repair; mild arthritis of the hip and back; asthma; hypertension; hearing loss; and depression;
2. The claimant does not have an impairment or combination of impairments that meets or medically equals an impairment listed in the regulations;
3. The claimant has the following residual functional capacity: light work except lifting and/or carrying greater than 10 pounds frequently and 20 pounds occasionally; work not requiring reaching above shoulder level with the dominant right upper extremity; work not requiring exposure to excessive concentrations of dust, gases, fumes, and poor ventilation; work at unprotected heights or around dangerous unguarded moving machinery; work requiring climbing and balancing or around loud noise; and work limited to a low stress environment defined as little to no change in work routine from day to day with avoidance of the general public;
4. Considering the claimant's age, education, work experience, residual functional capacity, and vocational expert testimony, there are jobs that exist in significant numbers in the national economy that the claimant can perform.
After the Appeals Council declined review on January 11, 2012, this appeal followed.
The court reviews the Commissioner's final decision to determine whether it is:
(1) based on proper legal standards; and (2) supported by substantial evidence in the record as a whole. See Tackett v. Apfel, 180 F.3d 1094, 1097 (9th Cir. 1999). "Substantial evidence" is more than a mere scintilla, but less than a preponderance. See Saelee v. Chater, 94 F.3d 520, 521 (9th Cir. 1996). It is ". . . such evidence as a reasonable mind might accept as adequate to support a conclusion." Richardson v. Perales, 402 U.S. 389, 402 (1971). The record as a whole, including both the evidence that supports and detracts from the Commissioner's conclusion, must be considered and weighed. See Howard v. Heckler, 782 F.2d 1484, 1487 (9th Cir. 1986); Jones v. Heckler, 760 F.2d 993, 995 (9th Cir. 1985). The court may not affirm the Commissioner's decision simply by isolating a specific quantum of supporting evidence. See Hammock v. Bowen, 879 F.2d 498, 501 (9th Cir. 1989). If substantial evidence supports the administrative findings, or if there is conflicting evidence supporting a particular finding, the finding of the Commissioner is conclusive. See Sprague v. Bowen, 812 F.2d 1226, 1229-30 (9th Cir. 1987). Therefore, where the evidence is susceptible to more than one rational interpretation, one of which supports the Commissioner's decision, the decision must be affirmed, see Thomas v. Barnhart, 278 F.3d 947, 954 (9th Cir. 2002), and may be set aside only if an improper legal standard was applied in weighing the evidence, see Burkhart v. Bowen, 856 F.2d 1335, 1338 (9th Cir. 1988).
In his motion for summary judgment, plaintiff argues: (1) the ALJ erred by disregarding lay witness evidence from plaintiff's wife, Wendy Brasher; (2) the ALJ erred by rejecting plaintiff's credibility; (3) the ALJ erred by not finding that fibromyalgia is a severe impairment; (4) the ALJ's residual functional capacity assessment is not supported by substantial evidence; and (5) hypothetical questions posed to the vocational expert did not accurately reflect plaintiff's limitations.
In determining whether a claimant is disabled, an ALJ generally must consider lay witness testimony concerning a claimant's ability to work. See Dodrill v. Shalala, 12 F.3d 915, 919 (9th Cir. 1993); 20 C.F.R. §§ 404.1513(d)(4) & (e), 416.913(d)(4) & (e). Indeed, "lay testimony as to a claimant's symptoms or how an impairment affects ability to work is competent evidence . . . and therefore cannot be disregarded without comment." See Nguyen v. Chater, 100 F.3d 1462, 1467 (9th Cir. 1996). Consequently, "[i]f the ALJ wishes to discount the testimony of lay witnesses, he must give reasons that are germane to each witness." Dodrill, 12 F.3d at 919. ALJ may cite same reasons for rejecting plaintiff's statements to reject third-party statements where the statements are similar. See Valentine v. Commissioner Soc. Sec. Admin., 574 F.3d 685, 694 (9th Cir. 2009) (approving rejection of a third-party family member's testimony, which was similar to the claimant's, for the same reasons given for rejection of the claimant's complaints).
The ALJ, however, need not discuss all evidence presented. See Vincent on Behalf of Vincent v. Heckler, 739 F.2d 1393, 1394-95 (9th Cir. 1984). Rather, he must explain why "significant probative evidence has been rejected." Id. (citing Cotter v. Harris, 642 F.2d 700, 706 (3d Cir.1981). Applying this standard, the court held that the ALJ properly ignored evidence which was neither significant nor probative. See id. at 1395. As to a letter from a treating psychiatrist, the court reasoned that, because the ALJ must explain why he rejected uncontroverted medical evidence, the ALJ did not err in ignoring the doctor's letter which was controverted by other medical evidence considered in the decision. See id. As to lay witness testimony concerning the plaintiff's mental functioning ...
