United States District Court, E.D. California
MEMORANDUM OPINION AND ORDER
CRAIG M. KELLISON, Magistrate Judge.
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. 20) and defendant's cross-motion for summary judgment (Doc. 22).
I. PROCEDURAL HISTORY
Plaintiff applied for social security benefits on April 30, 2010. In the application, plaintiff claims that disability began on April 30, 2010. Plaintiff claims that disability is caused by a combination of back pain, leg pain, left knee pain, and left ankle pain. Plaintiff's claim was initially denied. Following denial of reconsideration, plaintiff requested an administrative hearing, which was held on March 23, 2011, before Administrative Law Judge ("ALJ") Carol L. Buck. In an April 21, 2011, decision, the ALJ concluded that plaintiff is not disabled based on the following relevant findings:
1. The claimant has the following severe impairment(s): residual effects status post acute poliomyelitis (polio) which include mild-moderate back pain with mild left knee degenerative joint disease;
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: the claimant has the residual functional capacity to perform sedentary work; he is able to lift-carry 10 pounds occasionally and 5 pounds frequently; he is able to stand/walk for two hours in an eight-hour day; he is able to sit for six hours in an eight-hour day; he is able to stoop occasionally; he is restricted from climbing, balancing, and exposure to heights; he requires the use of a cane when ambulating all distances and over all terrains;
4. The claimant is capable of performing his past relevant work as an office clerk; and
5. Alternatively, considering the claimant's age, education, work experience, residual functional capacity, and vocational expert testimony, there are other jobs that claimant can perform that exist in significant numbers in the national economy.
After the Appeals Council declined review on November 13, 2012, this appeal followed.
II. STANDARD OF REVIEW
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 that the ALJ erred by: (1) ignoring treating physician opinion; (2) failing to establish that plaintiff's past relevant work in office jobs was substantial or gainful; (3) failing to carry the burden at step five of establishing that jobs exist in sufficient numbers; (4) not reviewing plaintiff's impairments under Listing 11.11; and (5) failing to properly assess credibility.
A. Evaluation of Medical Opinions
The weight given to medical opinions depends in part on whether they are proffered by treating, examining, or non-examining professionals. See Lester v. Chater , 81 F.3d 821, 830-31 (9th Cir. 1995). Ordinarily, more weight is given to the opinion of a treating professional, who has a greater opportunity to know and observe the patient as an individual, than the opinion of a non-treating professional. See id.; Smolen v. Chater , 80 F.3d 1273, 1285 (9th Cir. 1996); Winans v. Bowen , 853 F.2d 643, 647 (9th Cir. 1987). The least weight is given to the opinion of a non-examining professional. See Pitzer v. Sullivan , 908 F.2d 502, 506 & n.4 (9th Cir. 1990).
In addition to considering its source, to evaluate whether the Commissioner properly rejected a medical opinion the court considers whether: (1) contradictory opinions are in the record; and (2) clinical findings support the opinions. The Commissioner may reject an uncontradicted opinion of a treating or examining medical professional only for "clear and convincing" reasons supported by substantial evidence in the record. See Lester , 81 F.3d at 831. While a treating professional's opinion generally is accorded superior weight, if it is contradicted by an examining professional's opinion which is supported by different independent clinical findings, the Commissioner may resolve the conflict. See Andrews v. Shalala , 53 F.3d 1035, 1041 (9th Cir. 1995). A contradicted opinion of a treating or examining professional may be rejected only for "specific and legitimate" reasons supported by substantial evidence. See Lester , 81 F.3d at 830. This test is met if the Commissioner sets out a detailed and thorough summary of the facts and conflicting clinical evidence, states her interpretation of the evidence, and makes a finding. See Magallanes v. Bowen , 881 F.2d 747, 751-55 (9th Cir. 1989). Absent specific and legitimate reasons, the Commissioner must defer to the opinion of a treating or examining professional. See Lester , 81 F.3d at 830-31. The opinion of a non-examining professional, without other evidence, is insufficient to ...
