Factual and Procedural History 6 Plaintiff was born in 1975 and is currently 51 years of age. (AR 150.)3 She has a 7 bachelor’s degree in mathematics, served in the Navy from 2009 to 2010, and held previous 8 employment as a business finance manager. (AR 1203-04.) On March 21, 2018, she was 9 found disabled as of August 30, 2017, due to primary diagnoses of depressive, bipolar and 10 related disorders and secondary diagnoses of schizophrenia spectrum and other psychotic 11 disorders, which were found to meet Listing 12.04.4 (AR 150.) On September 15, 2020, in 12 a continuing disability review, the agency determined that Plaintiff was no longer disabled 13 as of September 1, 2020. (AR 172, 187-90.) A state agency Disability Hearing Officer 14 upheld this determination upon reconsideration. (AR 206-14.) Plaintiff then requested a 15 hearing before an Administrative Law Judge (“ALJ”). (AR 225.) 16 ALJ Kevin W. Messer conducted an administrative hearing on May 18, 2023 (AR 17 113), and a supplemental hearing on December 7, 2023 (AR 84). On April 3, 2024, the 18 ALJ issued a decision concluding that Plaintiff’s disability ended on September 1, 2020. 19 (AR 16-31.)

P, App. 1, Listing 12.04 (depressive, bipolar and 27 1 the request on September 30, 2024. (AR 1-7.) Plaintiff then commenced this action 2 pursuant to 42 U.S.C. § 405(g). 3 II. LEGAL STANDARDS 4 A. Qualifying for Disability Benefits 5 The Commissioner employs a five-step analysis outlined in 20 C.F.R. § 404.1520 to 6 determine whether a claimant is disabled within the meaning of the Social Security Act. 7 See 20 C.F.R. § 404.1520; see also Tackett v. Apfel, 180 F.3d 1094, 1098–99 (9th Cir. 8 1999) (describing five steps). At step one, the Commissioner determines whether the 9 claimant is engaging in substantial gainful activity. 20 C.F.R. § 404.1520(a)(4)(i). At step 10 two, the agency considers the medical severity of the impairment. Id. § 404.1520(a)(4)(ii). 11 At step three, the Commissioner determines whether the impairment meets or equals one 12 of a list of specific impairments described in the regulations. Id. § 404.1520(a)(4)(iii). At 13 step four, the agency considers whether the claimant is able to perform their past relevant 14 work. Id. § 404.1520(a)(4)(iv). At the last step, step five, the Commissioner evaluates the 15 claimant’s ability to perform other work. Id. § 404.1520(a)(4)(v). 16 B. Decisions of Continuing Disability 17 After a person is found to be entitled to disability benefits, the Commissioner is 18 required to periodically review whether continued entitlement to such benefits is 19 warranted. 20 C.F.R. § 404.1594(a). Such a person is no longer entitled to benefits when 20 substantial evidence demonstrates (1) “there has been any medical improvement in the 21 individual’s impairment” and (2) “the individual is now able to engage in substantial 22 gainful activity.” 42 U.S.C. § 423(f)(1)(A)-(B). To determine whether there has been 23 medical improvement, an ALJ is required to “‘compare the current medical severity’ of the 24 claimant’s impairment to the medical severity of the impairment ‘at the time of the most 25 recent favorable medical decision that [the claimant] w[as] disabled.’” Attmore v. Colvin, 26 827 F.3d 872, 873 (9th Cir. 2016) (citing 20 C.F.R. § 404.1594(b)(7)). 27 1 The Commissioner follows an eight-step evaluation process outlined in 20 C.F.R. § 2 404.1594 to make a determination of continuing disability. 20 C.F.R. § 404.1594(f). At 3 step one, the Commissioner determines whether the claimant is engaging in substantial 4 gainful activity. Id. § 404.1594(f)(1). At step two, the agency determines whether the 5 impairment meets or equals the severity of an impairment listed in the regulations. Id. § 6 404.1594(f)(2). At step three, the Commissioner determines whether medical improvement 7 has occurred. Id. § 404.1594(f)(3). At step four, the agency determines whether medical 8 improvement is related to the claimant’s ability to work. Id. § 404.1594(f)(4). At step five, 9 if needed, the Commissioner must determine if an exception to medical improvement 10 applies. Id. § 404.1594(f)(5).5 At step six, the agency determines whether all the claimant’s 11 current impairments are severe. Id. § 404.1594(f)(6). At step seven, the Commissioner 12 considers whether the claimant can perform their past relevant work. Id. § 404.1594(f)(7). 13 At the final step, step eight, the agency evaluates the claimant’s ability to perform other 14 work. Id. § 404.1594(f)(8). 15 C. Judicial Review of an ALJ’s Decision 16 Section 405(g) of the Social Security Act allows unsuccessful applicants to seek 17 judicial review of a final agency decision of the Commissioner. 42 U.S.C. § 405(g).
