Plaintiff, ORDER AFFIRMING FINAL v. DECISION OF THE COMMISSIONER OF SOCIAL FRANK BISIGNANO, Commissioner of Social Security,1 SECURITY Defendant.

On October 29, 2024, Plaintiff Adelquin D.2 initiated this action seeking judicial review under 42 U.S.C. § 405(g) of the finding by Defendant Commissioner of Social Security that she is no longer disabled under the Social Security Act. (Dkt. No. 1.) Defendant filed the Administrative Record on January 29, 2025. (Dkt. Nos. 9-10.) Plaintiff 1 Pursuant to Rule 25(d) of the Federal Rules of Civil Procedure, the Court substitutes Frank Bisignano, the current Commissioner of Social Security, as the defendant in this action.

2 The Court refers to Plaintiff using only her first name and last initial pursuant to the Court’s Civil Local Rules. See Civ LR 7.1(e)(6)(b). filed a merits brief on April 7, 2025. (Dkt. No. 13.) Defendant filed a responsive brief on June 5, 2025. (Dkt. No. 17.) Plaintiff filed a reply on June 20, 2025. (Dkt. No. 18.) For the following reasons, the final decision of the Commissioner is AFFIRMED. A. Factual and Procedural History Plaintiff was born in 1975 and is currently 51 years of age. (AR 150.)3 She has a bachelor’s degree in mathematics, served in the Navy from 2009 to 2010, and held previous employment as a business finance manager. (AR 1203-04.) On March 21, 2018, she was found disabled as of August 30, 2017, due to primary diagnoses of depressive, bipolar and related disorders and secondary diagnoses of schizophrenia spectrum and other psychotic disorders, which were found to meet Listing 12.04.4 (AR 150.) On September 15, 2020, in a continuing disability review, the agency determined that Plaintiff was no longer disabled as of September 1, 2020. (AR 172, 187-90.) A state agency Disability Hearing Officer upheld this determination upon reconsideration. (AR 206-14.) Plaintiff then requested a hearing before an Administrative Law Judge (“ALJ”). (AR 225.) ALJ Kevin W. Messer conducted an administrative hearing on May 18, 2023 (AR 113), and a supplemental hearing on December 7, 2023 (AR 84). On April 3, 2024, the ALJ issued a decision concluding that Plaintiff’s disability ended on September 1, 2020. (AR 16-31.) Plaintiff requested a review of the ALJ’s decision; the Appeals Council denied 3 “AR” refers to the Administrative Record filed on January 29, 2025. (Dkt. Nos. 9- 10.) The Court’s citations to the AR use the page references on the original document rather than the page numbers designated by the Court’s Case Management/Electronic Case Filing system (“CM/ECF”). For all other documents, the Court’s citations are to the page numbers affixed by CM/ECF. 4 See 20 C.F.R. Pt. 404, Subpt. P, App. 1, Listing 12.04 (depressive, bipolar and the request on September 30, 2024. (AR 1-7.) Plaintiff then commenced this action pursuant to 42 U.S.C. § 405(g). A. Qualifying for Disability Benefits The Commissioner employs a five-step analysis outlined in 20 C.F.R. § 404.1520 to determine whether a claimant is disabled within the meaning of the Social Security Act. See 20 C.F.R. § 404.1520; see also Tackett v. Apfel, 180 F.3d 1094, 1098–99 (9th Cir. 1999) (describing five steps). At step one, the Commissioner determines whether the claimant is engaging in substantial gainful activity. 20 C.F.R. § 404.1520(a)(4)(i). At step two, the agency considers the medical severity of the impairment. Id. § 404.1520(a)(4)(ii). At step three, the Commissioner determines whether the impairment meets or equals one of a list of specific impairments described in the regulations. Id. § 404.1520(a)(4)(iii). At step four, the agency considers whether the claimant is able to perform their past relevant work. Id. § 404.1520(a)(4)(iv). At the last step, step five, the Commissioner evaluates the claimant’s ability to perform other work. Id. § 404.1520(a)(4)(v). B. Decisions of Continuing Disability After a person is found to be entitled to disability benefits, the Commissioner is required to periodically review whether continued entitlement to such benefits is warranted. 20 C.F.R. § 404.1594(a). Such a person is no longer entitled to benefits when substantial evidence demonstrates (1) “there has been any medical improvement in the individual’s impairment” and (2) “the individual is now able to engage in substantial gainful activity.” 42 U.S.C. § 423(f)(1)(A)-(B). To determine whether there has been medical improvement, an ALJ is required to “‘compare the current medical severity’ of the claimant’s impairment to the medical severity of the impairment ‘at the time of the most recent favorable medical decision that [the claimant] w[as] disabled.’” Attmore v. Colvin, 827 F.3d 872, 873 (9th Cir. 2016) (citing 20 C.F.R. § 404.1594(b)(7)). The Commissioner follows an eight-step evaluation process outlined in 20 C.F.R. § 404.1594 to make a determination of continuing disability. 20 C.F.R. § 404.1594(f). At step one, the Commissioner determines whether the claimant is engaging in substantial gainful activity. Id. § 404.1594(f)(1). At step two, the agency determines whether the impairment meets or equals the severity of an impairment listed in the regulations. Id. § 404.1594(f)(2). At step three, the Commissioner determines whether medical improvement has occurred. Id. § 404.1594(f)(3). At step four, the agency determines whether medical improvement is related to the claimant’s ability to work. Id. § 404.1594(f)(4). At step five, if needed, the Commissioner must determine if an exception to medical improvement applies. Id. § 404.1594(f)(5).5 At step six, the agency determines whether all the claimant’s current impairments are severe. Id. § 404.1594(f)(6). At step seven, the Commissioner considers whether the claimant can perform their past relevant work. Id. § 404.1594(f)(7). At the final step, step eight, the agency evaluates the claimant’s ability to perform other work. Id. § 404.1594(f)(8). C. Judicial Review of an ALJ’s Decision Section 405(g) of the Social Security Act allows unsuccessful applicants to seek judicial review of a final agency decision of the Commissioner. 42 U.S.C. § 405(g). The scope of judicial review is limited, however, and a decision denying benefits will be set aside “only if it is not supported by substantial evidence or is based on legal error.” Ferguson v. O’Malley, 95 F.4th 1194, 1199 (9th Cir. 2024) (citations omitted). Substantial evidence means “‘more than a mere scintilla but less than a preponderance; it is such relevant evidence as a r
