Mao v. Commissioner of Social Security

United States District Court, E.D. California

March 31, 2014

TOEUR MAO, Plaintiff,
v.
COMMISSIONER OF SOCIAL SECURITY, Defendant.

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. 13) and defendant's opposition thereto (Doc. 14).

I. PROCEDURAL HISTORY

Plaintiff applied for social security benefits on February 23, 2009. In the application, plaintiff claims that disability began on January 1, 2005. Plaintiff claims that disability is caused by a combination of "headaches; high cholesterol; anemia; depression." Plaintiff's claim was initially denied. Following denial of reconsideration, plaintiff requested an administrative hearing, which was held on July 22, 2010, before Administrative Law Judge ("ALJ") Philip E. Callis. In a October 21, 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): recurrent major depressive disorder in remission; PTSD; low back pain due to sprain/strain; headaches and dizziness.
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 she can perform only non-public, simple, repetitive tasks with exposure to others not too intense or prolonged; she can occasionally climb, balance, stoop, kneel, crouch, and crawl; she must avoid concentrated exposure to extreme cold and hazards such as machinery and heights.
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 February 7, 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).

III. DISCUSSION

In her motion for summary judgment, plaintiff argues that the ALJ erred with respect to evaluation of the medical opinion evidence, specifically the opinions of Drs. Sharma, Friedman, Tran, and Wong. 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 ...
