Opinion

Case No. 25-cv-03681-NC Plaintiff, ORDER REVERSING v. ADMINISTRATIVE LAW JUDGE DECISION AND REMANDING FOR SECURITY, Re: ECF 9, 13, 14 Defendant. Claimant W.F. appeals from an Administrative Law Judge’s denial of disability benefits for the period beginning May 1, 2019. W.F. argues the ALJ erred in concluding his mental impairments did not meet a listing at step three of the sequential process and that the ALJ improperly weighed the medical opinions and medical evidence associated with W.F.’s mental impairments. W.F. also argues the ALJ erred in evaluating both his mental and physical impairments by discounting his testimony, determining his residual functional capacity (RFC), and disregarding vocational expert testimony. The Court agrees that the ALJ erred in weighing the medical opinions and evaluating the medical evidence for his mental impairments, particularly at step three. Because neither party argues these errors were harmless, the Court REVERSES the ALJ’s decision and REMANDS for further consideration and proceedings. The Court does not reach the parties’ remaining arguments. A. Procedural History W.F. filed an application for disability insurance benefits under Title II and Title XVI alleging a disability onset date of May 1, 2019. AR 1043. The claim was denied initially and upon reconsideration. AR 1043. The ALJ held a hearing on February 29, 2024, and issued an unfavorable decision on May 21, 2024. AR 1043, 1058. The Appeals Council denied W.F.’s request for review. AR 1–4. W.F. appealed to this Court on April 28, 2025. ECF 1. W.F. filed a brief in support of reversal and remand. ECF 9. The Commissioner opposed, seeking to affirm the ALJ’s decision. ECF 13. W.F. replied. ECF 14. All parties have consented to magistrate judge jurisdiction. ECF 5, 7. B. ALJ Decision The ALJ followed the five-step sequential process under 20 CFR § 404.1520(a) and § 416.920(a) to determine whether W.F. has been disabled for a 12-month period since May 1, 2019. At step one, the ALJ concluded W.F. has not engaged in substantial gainful activity since the alleged onset date. AR 1046. At step two, the ALJ concluded W.F. has the severe impairments of morbid obesity, bilateral inguinal hernia, generalized anxiety disorder, alcohol dependence in remission, and persistent depressive disorder. AR 1046. At step three, the ALJ concluded that W.F.’s impairments, singly or in combination, did not meet or medically equal a listed impairment, including for listings 5.02, 5.05, 5.06, 5.07, 5.08, 5.09, 12.04, and 12.06. AR 1047–50. Prior to step four, the ALJ concluded that W.F. has an RFC1 to perform medium work “except that he would need to work independently, meaning other individuals could be in the immediate vicinity but only incidental interactions are required in order to accomplish the essential functions of the

1 A claimant’s RFC is a determination of how much the claimant can still do in a work setting despite physical and mental limitations. 20 C.F.R. §§ 404.1545(a)(1), 416.945(a)(1). The ALJ must consider the limiting effects of all impairments, including job.” AR 1050–56. At steps four and five, the ALJ concluded W.F. could perform past relevant work as a janitor as well as other jobs that exist in significant numbers in the national economy. AR 1056–57. As such, the ALJ concluded W.F. was not disabled between May 1, 2019, and the date of his decision, May 21, 2024. AR 1057–58. A district court has the “power to enter, upon the pleadings and transcript of the record, a judgment affirming, modifying, or reversing the decision of the Commissioner of Social Security, with or without remanding the case for a rehearing.” 42 U.S.C. § 405(g). The decision of the Commissioner should only be disturbed if it is not supported by substantial evidence or if it is based on legal error. Burch v. Barnhart, 400 F.3d 676, 679 (9th Cir. 2005). Substantial evidence is evidence that a reasonable mind would accept as adequate to support the conclusion. Bayliss v. Barnhart, 427 F.3d 1211, 1214 n.1 (9th Cir. 2005) (“[It] is more than a mere scintilla but less than a preponderance”). Even when the ALJ commits legal error, the decision must be upheld if the error is harmless. Treichler v. Comm’r of Soc. Sec. Admin., 775 F.3d 1090, 1099 (9th Cir. 2014). However, “[a] reviewing court may not make independent findings based on the evidence before the ALJ to conclude that the ALJ’s error was harmless.” Brown-Hunter v. Colvin, 806 F.3d 487, 492 (9th Cir. 2015) (citing Stout v. Comm’r, Soc. Sec. Admin., 454 F.3d 1050, 1054 (9th Cir. 2006)). Where evidence is susceptible to more than one rational interpretation, the ALJ’s decision should be upheld. Andrews v. Shalala, 53 F.3d 1035, 1039–40 (9th Cir. 1995). W.F. argues the ALJ erred: (1) at step three in determining his mental impairments did not meet a listing; (2) by improperly weighing medical opinions; (3) in evaluating the medical evidence; (4) by discounting W.F.’s testimony; and (5) in formulating the RFC, including by ignoring vocational expert testimony. Because W.F.’s arguments on the ALJ’s treatment of the medical opinions and medical evidence are applicable to the ALJ’s weighing the medical opinions and medical evidence and, as a result, erred at step three. A. The ALJ Erred at Step Three A claimant is found disabled at step three if they have “an impairment(s) that meets or equals” a listing. 20 C.F.R.§§ 404.1520(a)(4)(iii), 416.920(a)(4)(iii). A listing is a “systems impairments that we consider to be severe enough to prevent an individual from doing any gainful activity, regardless of his or her age, education, or work experience.” 20 C.F.R. §§ 404.1525(a), 416.925(a). Each listing describes “the objective medical and other findings needed to satisfy the criteria of that listing.” 20 C.F.R. §§ 404.1525(c)(3), 416.925(c)(3). At step three, the ALJ concluded “the severity of the claimant’s mental impairments, considered singly and in combination, do not meet or medically equal the criteria of listings 12.04 and 12.06.” AR 1047. Listing 12.04 is for depressive, bipolar and related disorders, and listing 12.06 is for anxiety and obsessive-compulsive disorders. Both listings require a claimant to meet the criteria of either paragraphs A and B or paragraphs A and C. W.F. challenges the ALJ’s paragraph B findings. Paragraph B requires an “[e]xtreme limitation of one, or marked limitation of two, of the following areas of mental functioning (see 12.00F): 1. Understand, remember, or apply information (see 12.00E1). 2. Interact with others (see 12.00E2). 3. Concentrate, persist, or maintain pace (see 12.00E3). 4. Adapt or manage oneself (see 12.00E4).” The ALJ concluded W.F. did not meet the
