Plaintiff, OPINION AND ORDER

v.

COMMISSIONER SOCIAL SECURITY ADMINISTRATION,

Defendant.

BECKERMAN, U.S. Magistrate Judge. Charles S. (“Plaintiff”) filed this appeal challenging the Commissioner of Social Security’s (“Commissioner”) denial of his application for Disability Insurance Benefits (“DIB”) under Title II of the Social Security Act. The Court has jurisdiction over this matter pursuant to 42 U.S.C. §§ 405(g) and 1383(c)(3). For the reasons explained below, the Court affirms the Commissioner’s decision because it is free of harmful legal error and supported by substantial evidence. ///

1 In the interest of privacy, this opinion uses only the first name and the initial of the last name of the non-governmental party. STANDARD OF REVIEW “As with other agency decisions, federal court review of social security determinations is limited.” Treichler v. Comm’r of Soc. Sec. Admin., 775 F.3d 1090, 1098 (9th Cir. 2014). That is because “[f]or highly fact-intensive individualized determinations like a claimant’s entitlement to disability benefits, Congress places a premium upon agency expertise, and, for the sake of

uniformity, it is usually better to minimize the opportunity for reviewing courts to substitute their discretion for that of the agency.” Id. (quoting Consolo v. Fed. Mar. Comm’n, 383 U.S. 607, 621 (1966)). Adhering to this principle, courts “follow three important rules” in reviewing social security determinations. Brown-Hunter v. Colvin, 806 F.3d 487, 492 (9th Cir. 2015). First, courts “leave it to the [agency] to determine credibility, resolve conflicts in the testimony, and resolve ambiguities in the record.” Id. (quoting Treichler, 775 F.3d at 1098). Second, courts “will ‘disturb the Commissioner’s decision to deny benefits only if it is not supported by substantial evidence or is based on legal error.’” Id. (quoting Treichler, 775 F.3d at 1098). Third, if the agency “‘commits legal error, [courts] uphold the decision where that error is harmless,’ meaning that ‘it is inconsequential to the ultimate nondisability determination,’ or

that, despite the legal error, ‘the agency’s path may reasonably be discerned, even if the agency explains its decision with less than ideal clarity.’” Id. (quoting Treichler, 775 F.3d at 1098); see also Smith v. Kijakazi, 14 F.4th 1108, 1111 (9th Cir. 2021) (“And even where this modest [substantial evidence] burden is not met, [courts] will not reverse an [agency] decision where the error was harmless.” (citing Molina v. Astrue, 674 F.3d 1104, 1111 (9th Cir. 2012), superseded on other grounds by regulation as recognized in Farlow v. Kijakazi, 53 F.4th 485, 487 (9th Cir. 2022))). /// /// BACKGROUND I. PLAINTIFF’S APPLICATION Plaintiff filed a DIB application on May 16, 2019, alleging a disability onset date of August 18, 2018.2 (Tr. 291-95.) Following a hearing before an Administrative Law Judge (“ALJ”) on April 5, 2022 (id. at 56-86), the ALJ issued a written decision denying Plaintiff’s application. (Id. at 117-36.) The Appeals Council remanded the ALJ’s decision and Plaintiff

appeared at a second hearing on February 15, 2024, at which Plaintiff and a vocational expert (“VE”) testified. (Id. at 34-55.) On April 17, 2024, the ALJ issued a second written decision denying Plaintiff’s application. (Id. at 15-27.) On March 26, 2025, the Appeals Council denied Plaintiff’s request for review, making the ALJ’s written decision the final decision of the Commissioner. (Id. at 1-6.) Plaintiff now seeks judicial review of the ALJ’s decision. II. THE SEQUENTIAL PROCESS A claimant is considered disabled if he or she is unable to “engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which . . . has lasted or can be expected to last for a continuous period of not less than 12

2 To be eligible for DIB, “a worker must have earned a sufficient number of [quarters of coverage] within a rolling forty quarter period.” Herbert v. Astrue, No. 1:07-cv-01016 TAG, 2008 WL 4490024, at *4 (E.D. Cal. Sept. 30, 2008) (citation omitted). Workers accumulate quarters of coverage based on their earnings. Id. Typically, “the claimant must have a minimum of twenty quarters of coverage [during the rolling forty-quarter period to maintain insured status]. . . . The termination of a claimant’s insured status is frequently referred to as the ‘date last insured’ or ‘DLI.’” Id. (citation omitted). Thus, Plaintiff’s date last insured (“DLI”) of December 31, 2023 (Tr. 17) reflects the date on which his insured status terminated based on the previous accumulation of quarters of coverage. If Plaintiff established that he was disabled on or before December 31, 2023, he is entitled to DIB. See Truelsen v. Comm’r of Soc. Sec., No. 2:15- cv-2386-KJN, 2016 WL 4494471, at *1 (E.D. Cal. Aug. 26, 2016) (“To be entitled to DIB, plaintiff must establish that he was disabled . . . on or before his date last insured.” (citing Tidwell v. Apfel, 161 F.3d 599, 601 (9th Cir. 1998))). months[.]” 42 U.S.C. § 423(d)(1)(A). “Social Security Regulations set out a five-step sequential process for determining whether an applicant is disabled within the meaning of the Social Security Act.” Keyser v. Comm’r Soc. Sec. Admin., 648 F.3d 721, 724 (9th Cir. 2011). Those five steps are: (1) whether the claimant is engaged in substantial gainful activity; (2) whether the

claimant has a severe impairment; (3) whether the impairment meets or equals a listed impairment; (4) whether the claimant can return to any past relevant work; and (5) whether the claimant can perform other work that exists in significant numbers in the national economy. Id. at 724-25. The claimant bears the burden of proof for the first four steps. See Bustamante v. Massanari, 262 F.3d 949, 953-54 (9th Cir. 2001). If the claimant fails to meet the burden at any of those steps, the claimant is not disabled. See id. at 954. The Commissioner bears the burden of proof at step five, where the Commissioner must show the claimant can perform other work that exists in significant numbers in the national economy, “taking into consideration the claimant’s residual functional capacity, age, education, and work experience.” Tackett v. Apfel, 180 F.3d
