VAN DUONG, Plaintiff, v. MICHAEL J. ASTRUE, Commissioner of Social Security, Defendant.


ORDER

Plaintiff seeks judicial review of a final decision of the Commissioner of Social Security ("Commissioner") denying plaintiff's applications for Social Security Disability ("SSD") benefits under Title II of the Social Security Act and Supplemental Security Income ("SSI") benefits under Title XVI of the Social Security Act. (Dkt. No. 11.) In his motion for summary judgment, plaintiff alleges that the Administrative Law Judge ("ALJ") erred by (1) failing to properly calculate plaintiff's residual functional capacity ("RFC"); and (2) relying on improper or incomplete vocational expert ("VE") testimony. (("Pl.'s Memo.") Dkt. No. 18.)

This case was referred to the undersigned pursuant to Eastern District of California Local Rule 302(c)(15) and 28 U.S.C. § 636(c), and both parties voluntarily consented to proceed before a United States Magistrate Judge. (Dkt. Nos. 8, 15.)

After careful consideration of the entire record and the arguments submitted by the parties, for the reasons that follow, the court grants plaintiff's motion for summary judgment, denies the Commissioner's cross-motion for summary judgment, and remands this case for further proceedings. I. BACKGROUND

Because the parties are familiar with the factual background of this case, including plaintiff's medical history, the undersigned does not exhaustively relate those facts here. The facts related to plaintiff's impairments and medical history will be addressed only insofar as they are relevant to the issues presented by the parties' respective motions.

A. Procedural Background

Plaintiff applied for SSD and SSI benefits on February 21, 2008, alleging disability commencing on February 9, 2007 (See Administrative Transcript ("AT") 93-95, 96-103.) The Social Security Administration denied plaintiff's application initially and upon reconsideration. (AT 43-47, 48-52.) Plaintiff filed a request for a hearing before an ALJ, (AT 66), and a hearing was conducted regarding plaintiff's claim on October 7, 2009. (AT 18-38.) Plaintiff, who was represented by counsel at the hearing, appeared and testified at the hearing. (Id.) A vocational expert also testified at the hearing. (Id.)

In a decision dated February 22, 2010, the ALJ denied plaintiff's application. (See AT 9-17.) As discussed below, the ALJ determined that plaintiff was able to perform jobs that existed in significant numbers in the national economy. (AT 22.) The ALJ's decision became the final decision of the Commissioner when the Appeals Council denied plaintiff's request for review. (AT 3-6.) Plaintiff subsequently filed this action.

Disability Insurance Benefits are paid to disabled persons who have contributed to the Social Security program, 42 U.S.C. §§ 401 et seq. Generally speaking, SSI is paid to disabled persons with low income. 42 U.S.C. §§ 1382 et seq. Under both benefit schemes, the term "disability" is defined, in part, as an "inability to engage in any substantial gainful activity" due to "any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than twelve months." 42 U.S.C. §§ 423(d)(1)(A), 1382c(a)(3)(A). A five-step sequential evaluation governs eligibility for benefits. See 20 C.F.R. §§ 404.1520, 404.1571-1576, 416.920, 416.971-976; see also Bowen v. Yuckert, 482 U.S. 137, 140-42 (1987). The Ninth Circuit Court of Appeals has summarized the sequential evaluation as follows:

Step one: Is the claimant engaging in substantial gainful activity? If so, the claimant is found not disabled. If not, proceed to step two.
Step two: Does the claimant have a "severe" impairment? If so, proceed to step three. If not, then a finding of not disabled is appropriate.
Step three: Does the claimant's impairment or combination of impairments meet or equal an impairment listed in 20 C.F.R., Pt. 404, Subpt. P, App.1? If so, the claimant is automatically determined disabled. If not, proceed to step four.
Step four: Is the claimant capable of performing his past work? If so, the claimant is not disabled. If not, proceed to step five.
Step five: Does the claimant have the residual functional capacity to perform any other work? If so, the claimant is not disabled. If not, the claimant is disabled.

B. Relevant Medical Opinions

On April 18, 2008, consultative examiner Dr. Patrick Wong saw plaintiff for a psychological evaluation. (AT 192.) Dr. Wong assessed plaintiff's functional ability as follows:

[Plaintiff's] ability to carry out simple instructions is intact. Her ability to carry out complex instructions is mildly diminished by her depressive symptoms. Her ability to maintain an adequate pace and level of endurance is mild to moderately decreased by her depressive symptoms, her loss of stress tolerance, some issues with concentration and initiative. Her ability to relate to co-workers and the public is mildly to moderately impaired by this same pattern. Her ability to take directions from a supervisor on a sustained basis is mild to moderately affected as well. The probability of functional deterioration due to typical workplace stressors is probably moderately elevated due to her depressive symptoms. Her ability to adapt to changes in a workplace is mildly diminished to moderately diminished by her depressive symptoms. Ms. Duong is currently capable of staying consistently aware of safety issues in the workplace. Ms. Duong is currently capable of responsibly managing her own funds.
(At. 193-94.) The ALJ stated that he gave "great weight" to Dr. Wong's opinion. (AT 15.) Plaintiff does not challenge the ALJ's adoption of Dr. Wong's opinion; instead, plaintiff asserts the ALJ failed to adequately incorporate Dr. Wong's assessment into her RFC. (Pl.'s Memo. at 11-13.)

On May 7, 2008, state agency physician Kim Morris, reviewed plaintiff's case, including Dr. Wong's opinion. (AT 196-211.) In her mental residual functional capacity assessment, Dr. Morris checked the boxes for "Moderately Limited" in the following mental activities: ability to understand and remember detailed instructions; ability to carry out detailed instructions; ability to complete a normal workday and workweek without interruptions from psychologically based symptoms and to perform at a consistent pace without an unreasonable number and length of rest periods; ability to interact appropriately with the general public; ability to accept instructions and respond appropriately to criticism from supervisors; ability to respond appropriately to changes in the work setting. (AT 196-97.) All other mental activities were found by Dr. Morris to be "Not Significantly Limited." (Id.) There were no "Markedly Limited" mental activities. (Id.) In the "Functional Capacity Assessment" section of her report, Dr. Morris concluded that plaintiff has "sufficient ability": to understand and remember simple instructions; to complete simple instructions, to follow directions without additional assistance, and to maintain adequate attention for such tasks, to maintain appropriate behavior in a context of limited public contact, to be aware of ordinary hazards, to make simple decisions, to utilize transportation, and to cope with the demands of a routine, low stress position. (AT 198.) Dr. Morris further concluded that plaintiff is capable of accepting simply instructions and responding appropriately to feedback from supervisors. (Id.) The ALJ also gave "great weight" to Dr. Morris' opinion. (AT 14.) As with Dr. Wong's opinion, plaintiff asserts the ALJ failed to adequately incorporate Dr. Morris' opinion into her RFC. (Pl.'s Memo. at 11-13.)

C. Summary of the ALJ's Findings

The ALJ conducted the required five-step, sequential evaluation. At step one, the ALJ concluded that plaintiff had not engaged in substantial gainful activity since February 9, 2007, the alleged onset date. (AT 11.) At step two, the ALJ concluded that plaintiff had the severe impairments of "headaches and depression." (Id.) At step three, the ALJ found that plaintiff did not have an impairment or combination of impairments that met or medically equaled any impairment listed in the applicable regulations. (Id.)

The ALJ next assessed plaintiff's residual functional capacity ("RFC"). The ALJ found that:

[T]he claimant has the residual functional capacity to perform medium work as defined in 20 CFR 404.1567(c) and 416.967(c). Specifically, she can lift and carry 50 pounds occasionally and 25 pounds frequently, and can sit, stand, and walk six hours in an eight hour workday. The claimant can work at jobs requiring simple, routine tasks and can speak basic English, but cannot read or write English.
(AT 13.) In reaching his conclusion, the ALJ also discounted plaintiff's statements regarding the intensity, persistence, and limiting effects of his symptoms or impairments as not fully credible, a finding the plaintiff does not challenge in her motion for summary judgment. (AT 15.)

At step four, the ALJ found that plaintiff's RFC did not preclude plaintiff from performing her past relevant work as a production assembly worker. (AT 15.) Alternatively, the ALJ found, considering the plaintiff's age, education, work experience and RFC, that there are jobs that exist in significant numbers in the national economy that the plaintiff can perform. (AT 16.) Accordingly, the ALJ found plaintiff not disabled. (AT 17.)

II. STANDARDS OF REVIEW

The court reviews the Commissioner's decision to determine whether it is (1) free of legal error, and (2) supported by substantial evidence in the record as a whole. Bruce v. Astrue, 557 F.3d 1113, 1115 (9th Cir. 2009); accord Vernoff v. Astrue, 568 F.3d 1102, 1105 (9th Cir. 2009). This standard of review has been described as "highly deferential." Valentine v. Comm'r of Soc. Sec. Admin., 574 F.3d 685, 690 (9th Cir. 2009). "'Substantial evidence' means more than a mere scintilla but less than a preponderance; it is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion." Bray v. Comm'r of Soc. Sec. Admin., 554 F.3d 1219, 1222 (9th Cir. 2009) (quoting Andrews v. Shalala, 53 F.3d 1035, 1039 (9th Cir. 1995)); accord Valentine, 574 F.3d at 690 (citing Desrosiers v. Sec'y of Health & Human Servs., 846 F.2d 573, 576 (9th Cir. 1988)).

"The ALJ is responsible for determining credibility, resolving conflicts in medical testimony, and for resolving ambiguities." Andrews, 53 F.3d at 1039; see also Tommasetti, 533 F.3d at 1041 ("[T]he ALJ is the final arbiter with respect to resolving ambiguities in the medical evidence."). Findings of fact that are supported by substantial evidence are conclusive. 42 U.S.C. § 405(g); see also McCarthy v. Apfel, 221 F.3d 1119, 1125 (9th Cir. 2000). "Where the evidence as a whole can support either a grant or a denial, [the court] may not substitute [its] judgment for the ALJ's." Bray, 554 F.3d at 1222 (citing Massachi v. Astrue, 486 F.3d 1149, 1152 (9th Cir. 2007)); see also Ryan v. Comm'r of Soc. Sec., 528 F.3d 1194, 1198 (9th Cir. 2008) ("'Where evidence is susceptible to more than one rational interpretation,' the ALJ's decision should be upheld.") (quoting Burch v. Barnhart, 400 F.3d 676, 679 (9th Cir. 2005)). However, the court "must consider the entire record as a whole and may not affirm simply by isolating a 'specific quantum of supporting evidence.'" Ryan, 528 F.3d at 1198 (quoting Robbins v. Soc. Sec. Admin., 466 F.3d 880, 882 (9th Cir. 2006)); accord Lingenfelter v. Astrue, 504 F.3d 1028, 1035 (9th Cir. 2007).

III. DISCUSSION

Plaintiff argues that the ALJ erred by failing to include in her RFC the specific mild to moderate non-exertional limitations found in the opinions of Drs. Wong and Morris, opinions which the ALJ stated he gave "great weight". (See Pl.'s Memo. at 11-13.) Instead, the ALJ formulated an RFC that limited plaintiff to "jobs requiring simple, routine tasks." (AT 13.) Consequently, the hypothetical the ALJ posed to the vocational expert also did not include the specific mild to moderate non-exertional limitations assessed by Drs. Wong and Morris. (See AT 30-32.) Upon questioning by plaintiff's attorney, the vocational expert testified that if plaintiff's RFC did include the non-exertional limitations assessed by Dr. Wong, considered at a moderate level "at times," plaintiff would not be able to perform her past work or any other jobs existing in significant numbers in the national economy.

An ALJ's hypothetical questions to a vocational expert concerning what other work a claimant could perform must be based on a RFC that properly sets forth all of the claimant's impairments. A vocational expert's response to a hypothetical question premised on an incomplete RFC does not constitute competent evidence in support of a finding that a claimant could perform other work and is thus not disabled. See, e.g., Taylor v. Comm'r of Soc. Sec. Admin., 659 F.3d 1228, 1235 (9th Cir. 2011); Nguyen v. Chater, 100 F.3d 1462, 1466 n.3 (9th Cir. 1996).

Dr. Wong assessed plaintiff's limitations as "mild to moderate", whereas plaintiff's attorney posed a hypothetical to the vocational expert that described the limitations as "moderate", occurring "at times". (AT 35.)

The plaintiff's attorney asked the vocational expert:

Okay. I'd like you to consider hypothetical number three. And let us assume a person of the claimant's age, education, and past relevant work. The physical limitations as contained in the judge's hypothetical number two, which were sitting, standing or walking six of eight, 50 occasional, 25 frequently lifting, and simple repetitive tasks restriction, but I'd also like you to consider the following limitations as contained in exhibit 3-F, which are non-exertional limitations. The ability to maintain an adequate pace and level of endurance is as much as moderately decreased, ability to relate to coworkers and the public is, at times, as much as moderately impaired. Ability to take directions from a supervisor on a sustained basis, at times, is up to moderately affected, and the probability of functional deterioration due to typical workplace stressors is moderately elevated. The ability to adapt to changes in the workplace is, at times, as much as moderately diminished. If we add those non-exertional limitations, can such a person perform any of the claimant's past work - -
(AT 35.) The ALJ interjected for clarification as to how the vocational expert should understand the term "moderate", and plaintiff's attorney defined "moderate" as "more than occasionally, more than minimal, and it would also be defined as less than constant, and less than frequent". (AT 36.) The vocational expert then testified: "I would say that would be too severely impacted to perform the jobs I cited or her past relevant work." (Id.)

Specifically, plaintiff contends that the mental portion of the RFC did not reflect Dr. Wong's assessment that the plaintiff appeared mildly to moderately impaired in her ability to:

maintain an adequate pace and level of endurance; relate to coworkers and the public; take directions from a supervisor on a sustained basis; and adapt to changes in the workplace, with the probability of functional deterioration due to typical workplace stressors "probably" moderately elevated. (Id.)

The undersigned finds persuasive plaintiff's argument that the RFC formulated by the ALJ does not adequately capture plaintiff's limitations in terms of endurance and pace, relation to coworkers and the public, and ability to take directions and adapt to changes in the workplace. Even though Dr. Wong found a mild to moderate impairment in these mental abilities, the RFC arrived at by the ALJ does not reflect any such limitations. Instead, the RFC simply limits plaintiff to jobs involving "simple routine tasks." The practical result of the incomplete RFC relates to the adequacy of the ALJ's hypothetical questions to the vocational expert regarding other work that plaintiff could perform, and the adequacy of the vocational expert's responses that the ALJ relied on in finding plaintiff not disabled.

At step five of the analysis, the ALJ specifically asked the vocational expert about the work that a hypothetical person could perform with the mental component of the RFC limited to the ability to work in jobs involving "simple, routine tasks." (AT 31.) Because the premise of those hypothetical questions was incomplete, the vocational expert's resulting answers were incomplete and cannot serve as substantial evidence supporting the ALJ's non-disability determination.

In response, the Commissioner asserts that plaintiff's argument, that a RFC stating that plaintiff was capable of performing "simple routine tasks" did not capture limitations in pace and endurance, was rejected in Stubbs-Danielson v. Astrue, 539 F.3d 1169 (9th Cir. 2008). In Stubbs-Danielson, the Ninth Circuit Court of Appeals held that "an ALJ's assessment of a claimant adequately captures restrictions related to concentration, persistence, or pace where the assessment is consistent with restrictions identified in the medical testimony." Id. at 1174. There, the record contained some evidence of the claimant's slow pace, but the only concrete functional limitation provided by the medical sources was that the claimant could perform "simple tasks." Id. at 1173-74. As a result, the ALJ formulated a RFC that limited the claimant to "simple, routine, repetitive sedentary work." Id. at 1173. The Court of Appeals concluded that the ALJ did not err in that formulation of the RFC and, as a result, did not err in formulating hypothetical questions to the vocational expert. Id.

Conversely, this case is more akin to Brink v. Commissioner of the Social Security Administration, 343 Fed. Appx. 211 (9th Cir. 2009), which distinguished Stubbs-Danielson. Although Brink is an unpublished decision and thus only of persuasive value, it is instructive in regards to how it distinguished Stubbs-Danielson. In Brink, as in this case, the ALJ accepted medical evidence that Brink had difficulty with concentration, persistence, or pace, but posed hypothetical questions to the vocational expert based on a RFC that "referenced only 'simple, repetitive work,' without including limitations on concentration, persistence or pace." Id. at 212. In finding error and rejecting the Commissioner's argument premised on Stubbs-Danielson, the Court of Appeals reasoned:

Ninth Circuit Rule 36-3(b) provides: "Unpublished dispositions and orders of this Court issued on or after January 1, 2007 may be cited to the courts of this circuit in accordance with FRAP 32.1." However, Ninth Circuit Rule 36-3(a) provides: "Unpublished dispositions and orders of this Court are not precedent, except when relevant under the doctrine of law of the case or rules of claim preclusion or issue preclusion."

In Stubbs-Danielson v. Astrue, 539 F.3d 1169 (9th Cir. 2008), we held that an "assessment of a claimant adequately captures restrictions related to concentration, persistence, or pace where the assessment is consistent with the restrictions identified in the medical testimony." Id. at 1174. The medical testimony in Stubbs-Danielson, however, did not establish any limitations in concentration, persistence, or pace. Here, in contrast, the medical evidence establishes, as the ALJ accepted, that Brink does have difficulties with concentration, persistence, or pace. Stubbs-Danielson, therefore, is inapposite.
Id.

The undersigned finds that the reasoning of Brink is persuasive and supports a conclusion that Stubbs-Danielson does not control this case. In this case, as in Brink, the ALJ granted "great weight" to Dr. Wong's evidence of plaintiff's difficulty with endurance and pace, relation to coworkers and the public, and ability to take directions and adapt to changes in the workplace, but the RFC only included a reference to "simple, routine tasks." (AT 14-15.) The ALJ also granted "great weight" to the less restrictive opinion of the state agency physician, Dr. Morris, which perhaps on its own could support the RFC the ALJ reached. (AT 14.) However, if the ALJ did weigh the non-examining state agency's assessment more heavily than the opinion of examining physician Dr. Wong, the ALJ would be required to explain why he did so. Lester v. Chater, 81 F.3d 821, 830 (9th Cir. 1995) ("Generally, a treating physician's opinion should be accorded more weight than opinions of doctors who did not treat the claimant, and an examining physician's opinion is entitled to greater weight than a non-examining physician's opinion.")

The undersigned notes that other courts have found Brink persuasive and applied the reasoning of Brink in the manner similar to how the undersigned applies it here. See, e.g., Smith v. Astrue, No. ED CV 10-633-PLA, 2011 WL 3962107, at *8-9 (C.D. Cal. Sept. 8, 2011) (unpublished); Betancourt v. Astrue, No. EDCV 10-0196 CW, 2010 WL 4916604, at *3-4 (C.D. Cal. Nov. 27, 2010) (unpublished).

Plaintiff's RFC—which the ALJ subsequently used to question the vocational expert about plaintiff's past relevant work and other work in the national or regional economies that plaintiff could perform—did not adequately capture the opinion of Dr. Wong regarding the functional impact of plaintiff's mental impairment on plaintiff's ability to perform work in an eight-hour day, an opinion which the ALJ stated she gave "great weight." Accordingly, the undersigned concludes that the ALJ erred in formulating the RFC and that plaintiff is entitled to summary judgment. The court remands this matter to the agency for further development in regards to the formulation of a more accurate RFC for plaintiff insofar as her mental limitations are concerned. IV. CONCLUSION

Nothing herein is intended to suggest the ultimate outcome of such a remand.
--------

For the reasons stated above, IT IS HEREBY ORDERED that:

1. Plaintiff's motion for summary judgment (Dkt. No. 18) is granted and this matter is remanded to the ALJ for further proceedings as outlined above.

2. The Commissioner's cross-motion for summary judgment (Dkt. No. 23) is denied.

3. The Clerk of Court enter judgment in favor of the plaintiff.

IT IS SO ORDERED.
