Opinion

UNITED STATES DISTRICT COURT WESTERN DISTRICT OF WASHINGTON AT TACOMA CASE NO. 3:25-CV-6033-DWC Plaintiff, v. ORDER AFFIRMING DEFENDANT’S DECISION TO DENY BENEFITS COMMISSIONER OF SOCIAL Defendant.

Plaintiff filed this action pursuant to 42 U.S.C. § 405(g), seeking judicial review of Defendant’s denial of his applications for supplemental security income (“SSI”) and disability insurance benefits (“DIB”).1 The Court concludes that the Administrative Law Judge (“ALJ”) did not err in determining that Plaintiff was not disabled at Step Three of the Social Security sequential process, nor in considering Plaintiff’s subjective symptom testimony. Accordingly, the decision of the Commissioner of the Social Security Administration (“Commissioner”) is affirmed. 1 Pursuant to 28 U.S.C. § 636(c), Federal Rule of Civil Procedure 73, and Local Rule MJR 13, the parties have consented to have this matter heard by the undersigned Magistrate Judge. See Dkts. 2, 3. I. Procedural History Plaintiff filed his applications for SSI and DIB on March 29, 2022, alleging disability as of August 16, 2012. Dkt. 8, Administrative Record (“AR”) 182, 195. His claims were denied initially on February 9, 2023, and upon reconsideration on August 25, 2023. AR 182, 195, 240,

244. A hearing was held before ALJ David Johnson (“the ALJ”) on September 24, 2024, who issued a decision denying Plaintiff’s claim on November 25, 2024. AR 51–69. The Appeals Council denied Plaintiff’s request for review on September 30, 2025, making the ALJ’s decision the Commissioner’s final decision subject to judicial review. AR 1. From this decision, Plaintiff filed a complaint with this Court on November 20, 2025, seeking judicial review of the ALJ’s decision denying benefits. Dkt. 5. II. Standard of Review Pursuant to 42 U.S.C. § 405(g), this Court may set aside the Commissioner’s denial of social security benefits if the ALJ’s findings are based on legal error or are not supported by substantial evidence in the record as a whole. Bayliss v. Barnhart, 427 F.3d 1211, 1214 n.1 (9th

Cir. 2005) (citing Tidwell v. Apfel, 161 F.3d 599, 601 (9th Cir. 1999)). Substantial evidence is “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Biestek v. Berryhill, 587 U.S. 97, 103 (2019) (citation omitted). “We review only the reasons provided by the ALJ in the disability determination and may not affirm the ALJ on a ground upon which [they] did not rely.” Garrison v. Colvin, 759 F.3d 995, 1010 (9th Cir. 2014). “[H]armless error principles apply in the Social Security Act context.” Molina v. Astrue, 674 F.3d 1104, 1115 (9th Cir. 2012), superseded on other grounds by 20 C.F.R. § 404.1502(a). Generally, an error is harmless if it is not prejudicial to the claimant and is “inconsequential to

the ultimate nondisability determination.” Stout v. Comm’r, Soc. Sec. Admin., 454 F.3d 1050, 1055 (9th Cir. 2006); see also Molina, 674 F.3d at 1115. III. Discussion In his Opening Brief, Plaintiff argues that the ALJ erred in (1) failing to find Plaintiff

disabled at Step Three pursuant to Listing 12.04, and (2) in considering Plaintiff’s subjective symptom testimony. Dkt. 12 at 1. A. Step Three Determination Plaintiff argues that the ALJ erred in concluding that Plaintiff was not disabled at Step Three of the Social Security sequential process pursuant to Listing 12.04. Dkt. 12 at 4. At Step Three of the sequential evaluation process, the ALJ considers whether one or more of the claimant’s impairments meets or equals an impairment listed in Appendix 1 to Subpart P of the regulations. 20 C.F.R. §§ 404.1520(a)(4)(iii), 416.920(a)(4)(iii). Each Listing sets forth the “symptoms, signs and laboratory findings” that must be established for an impairment to meet the Listing. Tackett v. Apfel, 180 F.3d 1094, 1099 (9th Cir. 1999) (citation

omitted). “If a claimant meets or equals a listed impairment [they] will be found disabled at this step without further inquiry.” Id.; see also 20 C.F.R. §§ 404.1520(d), 416.920(d). A mental or physical impairment “must result from anatomical, physiological, or psychological abnormalities that can be shown by medically acceptable clinical and laboratory diagnostic techniques.” Social Security Ruling (“SSR”) 96-4p, 1996 WL 374187, at *1. The impairment must be established by medical evidence “consisting of signs, symptoms, and laboratory findings[.]” Id. An impairment meets a listed impairment “only when it manifests the specific findings described in the set of medical criteria for that listed impairment.” SSR 83-19, 1983 WL 31248, at *2.

“Listed impairments are purposefully set at a high level of severity because ‘the listings were designed to operate as a presumption of disability that makes further inquiry unnecessary.’” Kennedy v. Colvin, 738 F.3d 1172, 1176 (9th Cir. 2013) (quoting Sullivan v. Zebley, 493 U.S. 521, 532 (1990)). The burden of proof is on the claimant to establish that they meet or equal any

of the impairments in the Listings at Step Three. See Tackett, 180 F.3d at 1098 (“The burden of proof is on the claimant as to [S]teps one to four.”). “A generalized assertion of functional problems[,]” however, “is not enough to establish disability at [S]tep [T]hree.” Id. at 1100 (citing 20 C.F.R. § 404.1526). Listing 12.04 governs “[d]epressive, bipolar and related disorders[,]” and contains “three paragraphs, designated A, B, and C.” 20 C.F.R. Pt. 404, Subpt. P, App. 1, 12.00(a)(2). To meet Listing 12.04, a claimant’s mental disorder must satisfy the requirements of paragraph A and either paragraph B or C. Id.2 Paragraph A requires medical documentation of certain symptoms. Id. at 12.04(A). Paragraph B requires “[e]xtreme limitation of one, or marked limitation of two, of the following areas of mental functioning[,]” including: (1) understanding, remembering, or
