The opinion of the court was delivered by: Patrick J. Walsh United States Magistrate Judge
MEMORANDUM OPINION AND ORDER
Before the Court is Plaintiff's appeal from a decision by Defendant Social Security Administration ("the Agency"), denying his application for supplemental security income ("SSI"). Plaintiff claims that the Administrative Law Judge ("ALJ") erred when he:
1) failed to properly consider the opinion of Plaintiff's treating physician; 2) failed to develop the record with respect to the treating physician's opinion; and 3) concluded that Plaintiff could perform the jobs of hand packager and kitchen helper. Because the Agency's decision that Plaintiff was not disabled within the meaning of the Social Security Act is supported by substantial evidence, it is affirmed.
II. SUMMARY OF PROCEEDINGS
Plaintiff applied for SSI on March 16, 2006, alleging that he had been unable to work since January 1, 1999, because of asthma and back and neck pain. (Administrative Record ("AR") 10, 114, 118.) The Agency denied the application initially and on reconsideration. (AR 52-56, 59-63.) Plaintiff then requested and was granted a hearing before an ALJ. (AR 65, 73-75.) Plaintiff appeared at the hearing with counsel and testified. (AR 21-32.) Subsequently, Plaintiff requested and was granted a supplemental hearing, at which a medical expert and a vocational expert testified. (AR 33-48.) On July 16, 2003, the ALJ issued a decision, finding that Plaintiff was not disabled. (AR 10-18.) Plaintiff appealed to the Appeals Council, which denied review. (AR 1-4.) He then commenced this action.
1. The ALJ's Rejection of the Treating Physician's Opinion
In his first claim of error, Plaintiff contends that the ALJ erred when he rejected the treating doctor's opinion. (Joint Stip. 3-5, 10-11.) For the following reasons, the Court concludes that the ALJ's rejection of the treating doctor's opinion was not erroneous.
A treating physician's opinion is generally entitled to greater weight than a non-treating physician's opinion. See Andrews v. Shalala, 53 F.3d 1035, 1041 (9th Cir. 1995) (citing Magallanes v. Bowen, 881 F.2d 747, 751 (9th Cir. 1989)); Sprague v. Bowen, 812 F.2d 1226, 1230 (9th Cir. 1987). "The treating physician's opinion is not, however, necessarily conclusive as to either a physical condition or the ultimate issue of disability." Magallanes, 881 F.2d at 751. The weight given a treating physician's opinion depends on whether it is supported by sufficient medical data and whether it is consistent with other evidence in the record. See 20 C.F.R. § 404.1527(d)(2). Where, as here, the treating physician's opinion is contradicted, an ALJ may reject the opinion by providing "'specific and legitimate reasons'" for doing so that are supported by substantial evidence. Rollins v. Massanari, 261 F.3d 853, 856 (9th Cir. 2001) (quoting Reddick v. Chater, 157 F.3d 715, 720 (9th Cir. 1998).
In 2005 and 2006, Dr. Truong completed three pre-printed, check-the-box forms in which he repeatedly opined that Plaintiff's asthma and fatigue left him unable to work. (AR 188-91.) Subsequently, in 2007, at the request of Plaintiff's attorney, Dr. Truong filled out another, slightly more detailed form, in which he indicated, among other things, that Plaintiff's asthma would cause him to miss work about twice a month and that Plaintiff should avoid exposure to various air pollutants and extreme cold and heat. (AR 220-21.)
The ALJ ultimately rejected Dr. Truong's opinion. In doing so, he found that Dr. Truong had failed to include any basis for his conclusions contained in the check-the-box forms and that the medical record did not support these conclusions. (AR 14.) The ALJ also noted that Dr. Truong's opinion could not be reconciled with his treatment notes or with the relatively conservative treatment that he had prescribed for Plaintiff. (AR 14.) Further, the ALJ found that Dr. Truong's opinion regarding the purportedly debilitating impact of Plaintiff's asthma conflicted with other medical evidence in the record. (AR 14.) These are specific and legitimate reasons for discounting Dr. Truong's opinion and they are supported by substantial evidence in the record. For this reason, the ALJ's decision will not be disturbed. See Connett v. Barnhart, 340 F.3d 871, 875 (9th Cir. 2003) (holding ALJ properly rejected treating physician's opinion where physician's "extensive conclusions regarding [claimant's] limitations are not supported by his own treatment notes"); see also Tommasetti v. Astrue, 533 F.3d 1035, 1041 (9th Cir. 2008) (holding that ALJ properly discredited doctor's opinion where doctor's responses to questionnaire were inconsistent with doctor's own medical records).*fn1
Plaintiff argues that, because the ALJ did not specifically discuss each finding in Dr. Truong's Residual Functioning Capacity Report (AR 220-21), the matter must be remanded. Again, the Court disagrees. An ALJ is not required to discuss every piece of evidence in the record. See Howard ex rel. Wolff v. Barnhart, 341 F.3d 1006, 1012 (9th Cir. 2003) (holding ALJ is not required to discuss every piece of evidence so long as the decision is supported by substantial evidence). Rather, he need only explain why significant probative evidence has been rejected. Vincent v. Heckler, 739 F.2d 1393, 1395 (9th Cir. 1984) (per curiam). And, as explained above, the ALJ did that. He found that Dr. Truong's overall opinion that Plaintiff's asthma would preclude him from working was not supported by the record. He was not required to discuss each ...
