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 of a decision by Defendant Social Security Administration ("the Agency"), denying her application for Disability Insurance benefits ("DIB"). Plaintiff claims that the Administrative Law Judge ("ALJ") erred when he: 1) failed to find that Plaintiff's fibromyalgia was a severe impairment at step two of the sequential disability analysis; and 2) rejected a treating doctor's opinion that she could not work. (Joint Stip. at 3-4, 8-10.) Because the Agency's decision that Plaintiff was not disabled is supported by substantial evidence, it is affirmed.
II. SUMMARY OF PROCEEDINGS
Plaintiff applied for DIB on March 27, 2006, alleging that she had been unable to work since February 19, 2005, because of fibromyalgia and, more specifically, "increasing stiffness and headaches, hand coordination, trouble sleeping, constant muscle pain and trouble with memory." (Administrative Record ("AR") 25, 51, 72.) The Agency denied the application initially and on reconsideration. (AR 23-30.) Plaintiff then requested and was granted a hearing before an ALJ. (AR 33, 46-50.) Plaintiff appeared with counsel and testified at the hearing on September 12, 2008. (AR 287-315.) On November 13, 2008, the ALJ issued a decision denying benefits. (AR 12-21.) Plaintiff appealed to the Appeals Council, which denied review. (AR 5-8, 285.) She then commenced the instant action.
1. The ALJ's Failure to Consider Plaintiff's Fibromyalgia at Step Two Was Harmless Error
In her first claim of error, Plaintiff contends that the ALJ erred in failing to properly consider her fibromyalgia at step two. Plaintiff argues that the medical record, including a longitudinal history of diagnosis and treatment, demonstrates that she suffers from severe fibromyalgia. (Joint Stip. at 3-4.) For the following reasons, the Court concludes that, even assuming that the ALJ erred in failing to find that Plaintiff's fibromyalgia was a severe impairment at step two, any error was harmless.
At step two of the sequential evaluation process, the ALJ is tasked with identifying a claimant's "severe" impairments. 20 C.F.R. § 404.1520(a)(4)(ii). A severe impairment is one that significantly limits an individual's physical or mental ability to do basic work activities. Smolen v. Chater, 80 F.3d 1273, 1290 (9th Cir. 1996); 20 C.F.R. § 404.1521(a). The governing regulations define "basic work activities" as "the abilities and aptitudes necessary to do most jobs." 20 C.F.R. § 404.1521(b). Under Social Security Ruling ("SSR") 85-28, a "determination that an impairment(s) is not severe requires a careful evaluation of the medical findings which describe the impairment(s) and an informed judgment about its (their) limiting effects on the individual's physical and mental ability(ies) to perform basic work activities[.]" A claimant's subjective symptoms must be considered in this evaluation. Smolen, 80 F.3d at 1290. The step-two inquiry is intended to be a "de minimis screening device." Id. (citing Bowen v. Yuckert, 482 U.S. 137, 153-54 (1987)).
The ALJ found at step two that Plaintiff's shoulder girdle myositis with tension headache, hypertension, obesity, and depressive disorder, not otherwise specified, were severe impairments. (AR 14.) It is not clear why the ALJ did not include her fibromyalgia, given that he noted that, "[u]pon application, [Plaintiff] cited fibromyalgia as the sole condition preventing her from sustaining substantial gainful activity[,]" and that Plaintiff complained that this condition caused her constant pain and cramping in her legs, back, and chest, difficulty reaching and bending, knots in her back, and pain in her chest. (AR 16.) The ALJ also accepted that Plaintiff's medically determinable impairments could reasonably be expected to cause her alleged symptoms. (AR 17.) Because those symptoms included the symptoms caused by fibromyalgia, (AR 16-17), the ALJ's decision implies that he found that fibromyalgia was a medically determinable impairment. (AR 17.) Further, because the symptoms that Plaintiff complained of, if believed, had a more than minimal effect on her ability to do basic work activities, the ALJ should have found that her fibromyalgia was a severe impairment.*fn1
Nevertheless, assuming that the ALJ erred at step two, any error was harmless because the ALJ accounted for the symptoms and limitations allegedly caused by her fibromyalgia in his residual functional capacity determination at step four. After concluding that Plaintiff's severe impairments, singly or in combination, did not meet or equal a Listed Impairment, the ALJ determined that Plaintiff had the residual functional capacity to do light work.*fn2 (AR 14-16.) In making this determination, the ALJ expressly considered the symptoms Plaintiff attributed in whole or in part to her fibromyalgia, including her complaints of constant pain and cramping in her legs, back, and chest; difficulty reaching and bending; stiffness; headaches; hand coordination; trouble sleeping; nausea; dizziness; and exhaustion. (AR 16.) The ALJ concluded that her medically-determinable impairments could reasonably be expected to produce the alleged symptoms, but discounted Plaintiff's testimony to the extent that her description of the intensity and scope of her symptoms was inconsistent with his residual functional capacity assessment. (AR 17.) He did so, in part, based on the opinions of the state agency reviewing doctors, who found that Plaintiff could do medium-level work, and on the opinion of consultative neurologist Dr. Woodward, who examined Plaintiff and concluded that her neurological status did not significantly limit her physical abilities. (AR 17.) Dr. Woodward opined that Plaintiff's gait was normal and that her extremities seemed to be in the "normal range with respect to muscular power and coordination," concluding that "it is likely that depression and anxiety are contributing to much of [her] symptomatology" and that she was not significantly limited with respect to her physical activities as a result of her "neurologic status." (AR 283-84.)
Because the ALJ considered the limitations arising from Plaintiff's fibromyalgia at step four, any failure on his part to find that fibromyalgia was a severe impairment at step two was harmless error. See Lewis v. Astrue, 498 F.3d 909, 911 (9th Cir. 2007) (holding that ALJ's error in finding an impairment non-severe at step two was harmless when ALJ considered limitations resulting from impairment at step four) (citing Stout v. Comm'r, Soc. Sec. Admin., 454 F.3d 1050, 1054-55 (9th Cir. 2006)); see also Cotton v. Astrue, 2010 WL 1258262, at *2 (9th Cir. Apr. 2, 2010) (finding that any error by the ALJ in failing to include fibromyalgia as a severe impairment was harmless where the ALJ concluded that the claimant should be limited to light work due to the possibility that she might have fibromyalgia). For these reasons, this claim does not warrant reversal or remand.
2. The Treating Doctor's Opinion
In her second claim of error, Plaintiff contends that the ALJ erred by failing to provide legitimate reasons for rejecting an April 18, 2007 opinion of Dr. Mariclem Lao, Plaintiff's primary treating physician. (Joint Stip. at 8-10.) ...
