Opinion

UNITED STATES DISTRICT COURT WESTERN DISTRICT OF WASHINGTON AT SEATTLE Plaintiff, Case No. C25-1521-MLP v. ORDER Defendant. I. INTRODUCTION Plaintiff seeks review of the denial of her application for Disability Insurance Benefits. Plaintiff contends that the administrative law judge (“ALJ”) erred at step two, and by failing to incorporate limitations from accepted medical opinions into the residual functional capacity (“RFC”) finding. (Dkt. # 12.) The Commissioner filed a response arguing that the ALJ’s decision is free of legal error, supported by substantial evidence, and should be affirmed. (Dkt. # 16.) Plaintiff did not file a reply. Having considered the ALJ’s decision, the administrative record (“AR”), and the parties’ briefing, the Court AFFIRMS the Commissioner’s final decision and DISMISSES the case with prejudice.1

1 The parties consented to proceed before the undersigned Magistrate Judge. (Dkt. # 2.) Plaintiff was born in October 1978, has a greater than high school education, and has worked as a financial planner. AR at 188, 232, 764. Plaintiff was last gainfully employed in 2018. Id. at 209. In July 2022, Plaintiff applied for benefits, alleging disability as of February 5,

2021. Id. at 188. Plaintiff’s applications were denied initially and on reconsideration, and Plaintiff requested a hearing. Id. at 17. After the ALJ conducted a hearing in August 2024, the ALJ issued a decision finding Plaintiff not disabled. Id. at 17, 32. Using the five-step disability evaluation process,2 the ALJ found, in pertinent part, that Plaintiff has the severe impairments of post-concussive syndrome, traumatic brain injury, headaches, neurocognitive disorder, lumbar and cervical degenerative disc disease, depressive disorder, and anxiety disorder. AR at 19. The ALJ determined that Plaintiff can perform light work with additional postural and exertional limitations; can understand and remember simple, routine tasks and sustain them for two-hour intervals over an eight-hour workday; and can tolerate occasional interaction with the public and occasional changes in the routine work setting.

Id. at 22. As the Appeals Council denied Plaintiff’s request for review, the ALJ’s decision is the Commissioner’s final decision. AR at 1-6. Plaintiff appealed the final decision of the Commissioner to this Court. (Dkt. # 4.) Under 42 U.S.C. § 405(g), this Court may overturn the Commissioner’s denial of social security benefits if the ALJ’s decision rests on legal error or is not supported by substantial evidence. Smartt v. Kijakazi, 53 F.4th 489, 494 (9th Cir. 2022). Substantial evidence is defined

2 20 C.F.R. § 404.1520. as “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Biestek v. Berryhill, 587 U.S. 97, 102-03 (2019) (cleaned up). In applying this standard, the Court must consider the record as a whole to determine whether it contains sufficient evidence to support the ALJ’s findings. Id.

Although the Court evaluates the record as a whole, it is not permitted to reweigh the evidence or substitute its judgment for that of the ALJ. Ahearn v. Saul, 988 F.3d 1111, 1115 (9th Cir. 2021). The ALJ is tasked with evaluating testimony, resolving conflicts in the medical evidence, and addressing ambiguities in the record. Smartt, 53 F.4th at 494-95. Where the evidence can be interpreted in more than one rational way, the ALJ’s decision must be upheld. Id. Even if the ALJ erred, reversal is not warranted unless the error affected the outcome of the disability determination. Ford v. Saul, 950 F.3d 1141, 1154 (9th Cir. 2020). The party challenging the ALJ’s decision bears the burden of demonstrating harmful error. Shinseki v. Sanders, 556 U.S. 396, 409 (2009).

A. The ALJ Did Not Err at Step Two Plaintiff argues the ALJ erred at step two by failing to include her benign paroxysmal positional vertigo (“BPPV”) as a severe impairment. (Dkt. # 12 at 2-13.) The Commissioner responds that the ALJ properly considered BPPV as a symptom of Plaintiff’s severe impairments, and, in any event, any step-two error was harmless because step two was decided in Plaintiff’s favor. (Dkt. # 16 at 2-10.) Step two is a threshold determination meant to screen out weak claims. Buck v. Berryhill, 869 F.3d 1040, 1048 (9th Cir. 2017) (citing Bowen v. Yuckert, 482 U.S. 137, 146-47 (1987)). The ALJ must determine whether the claimant has a “severe” impairment. 20 C.F.R. § 404.1520(c). If the claimant has at least one severe impairment, the evaluation proceeds to step three. 20 C.F.R. § 404.1520(d). A claimant generally cannot be prejudiced by the ALJ’s failure to find a particular impairment severe at step two so long as the ALJ finds at least one severe impairment and

considers the functional effects of all impairments when assessing the RFC. Buck, 869 F.3d at 1049; Social Security Ruling 96-8p, 1996 WL 374184, at *5. “The RFC therefore should be exactly the same regardless of whether certain impairments are considered ‘severe’ or not.” Buck, 869 F.3d at 1049. Even if the ALJ erred in not listing BPPV as a severe impairment at step two, any error was harmless. At step four, the ALJ expressly discussed evidence related to Plaintiff’s dizziness, noting that she “complained of dizziness when requested to perform heel, toe, and tandem walking, squatting, and spinal range of motion and did not perform said maneuvers,” and accordingly limited her “to light work including the postural and environmental limitations as described in the residual functional capacity,” incorporating those limitations into the RFC

formulation. AR at 26-27; see Lewis v. Astrue, 498 F.3d 909, 911 (9th Cir. 2007). 1. The ALJ Did Not Err in Evaluating Plaintiff’s Testimony Within her step-two argument, Plaintiff asserts that the ALJ failed to provide sufficient explanation for discounting her testimony regarding BPPV. (Dkt. # 12 at 11-13.) The ALJ, however, reasonably discounted her subjective testimony as inconsistent with the objective medical evidence, including her positive response to treatment, and with her activities of daily living. AR at 24. Absent evidence of malingering, an ALJ must provide clear and convincing reasons for discounting a claimant’s testimony. See Laborin v. Berryhill, 867 F.3d 1151, 1155 (9th Cir. 2017). That said, the ALJ is not required to believe every allegation, nor to analyze testimony line by line. See Ahearn, 988 F.3d at 1116; Lambert v. Saul, 980 F.3d 1266, 1277 (9th Cir. 2020). The question is not whether this Court is convinced, “but instead whether the ALJ’s rationale is clear enough that it has the power to convince.” Smartt, 53 F.4th at 499.
