BAGGIO, District Judge:

Plaintiff Mariah C. brings this action seeking judicial review of the Commissioner’s final decision to deny disability insurance benefits (“DIB”). This Court has jurisdiction pursuant to 42 U.S.C. § 405(g). The Court reverses the Commissioner’s decision and remands this case for immediate payment of benefits. PROCEDURAL BACKGROUND Plaintiff applied for DIB on May 29, 2018, alleging an onset date of October 11, 2017. Tr. 70-71.2 Plaintiff’s date last insured (“DLI”) is December 31, 2027. Tr. 1691. Her application was denied initially and on reconsideration. Tr. 112-121. On March 21, 2021, Plaintiff appeared with counsel for a hearing before an Administrative Law Judge (“ALJ”). Tr. 30-68. On April 12, 2021, the ALJ found Plaintiff not disabled. Tr. 10-23. The Appeals Council denied review. Tr. 1. Plaintiff appealed, and this Court remanded the ALJ’s decision for further proceedings. Tr. 1780-95. On September 12, 2024, Plaintiff appeared with counsel for her second hearing before an ALJ. Tr. 1718-51. On September 18, 2024, the ALJ again found Plaintiff not disabled. Tr. 1688-1708. This timely appeal followed. Compl., ECF No. 1.

2 Citations to “Tr.” refer to the page(s) indicated in the official transcript of the administrative record, filed herein as ECF No. 8. FACTUAL BACKGROUND Plaintiff alleges disability based on fibromyalgia; chronic headaches; anxiety with panic attacks; irritable bowel syndrome; nausea; vomiting; muscle spasms; weakness and chronic fatigue; insomnia; difficulty focusing, concentrating, and remembering; depression; hypermobility; and pain in her jaw, neck, shoulders, back, and legs. Tr. 71. At the time of her

alleged onset date, she was 35 years old. Tr. 70. She has at least a high school education and past relevant work experience as a veterinary assistant. Tr. 1706. SEQUENTIAL DISABILITY EVALUATION A claimant is disabled if they are 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 months . . . .” 42 U.S.C. §§ 423(d)(1)(A), 1382c(a)(3)(A). Disability claims are evaluated according to a five-step procedure. See Valentine v. Comm’r, 574 F.3d 685, 689 (9th Cir. 2009) (in social security cases, agency uses five-step procedure to determine disability). The claimant bears the ultimate burden

of proving disability. Id. In the first step, the Commissioner determines whether a claimant is engaged in “substantial gainful activity.” If so, the claimant is not disabled. Bowen v. Yuckert, 482 U.S. 137, 140 (1987); 20 C.F.R. §§ 404.1520(b), 416.920(b). In step two, the Commissioner determines whether the claimant has a “medically severe impairment or combination of impairments.” Yuckert, 482 U.S. at 140–41; 20 C.F.R. §§ 404.1520(c), 416.920(c). If not, the claimant is not disabled. Id. In step three, the Commissioner determines whether the claimant’s impairments, singly or in combination, meet or equal “one of a number of listed impairments that the [Commissioner] acknowledges are so severe as to preclude substantial gainful activity.” Yuckert, 482 U.S. at 141; 20 C.F.R. §§ 404.1520(d), 416.920(d). If so, the claimant is conclusively presumed disabled; if not, the Commissioner proceeds to step four. Yuckert, 482 U.S. at 141. In step four, the Commissioner determines whether the claimant, despite any impairment(s), has the residual functional capacity (RFC) to perform their “past relevant work.”

20 C.F.R. §§ 404.1520(e), 416.920(e). If the claimant can perform past relevant work, the claimant is not disabled. If the claimant cannot perform past relevant work, the burden shifts to the Commissioner. In step five, the Commissioner must establish that the claimant can perform other work. Yuckert, 482 U.S. at 141–42; 20 C.F.R. §§ 404.1520(e)–(f), 416.920(e)–(f). If the Commissioner meets their burden and proves that the claimant can perform other work that exists in the national economy, then the claimant is not disabled. 20 C.F.R. §§ 404.1566, 416.966. THE ALJ’S DECISION At step one, the ALJ determined that Plaintiff had engaged in substantial gainful activity

after her alleged onset date during the second quarters of 2023 and 2024. Tr. 1691. The ALJ, however, also concluded there had been a continuous 12-month period where Plaintiff did not engage in substantial gainful activity. Tr. 1691-92. Next, at steps two and three, the ALJ determined that Plaintiff has the following severe impairments: “multi-level degenerative disc disease; small fiber neuropathy; tension headaches; fibromyalgia; chronic fatigue syndrome; major depressive disorder; panic disorder with agoraphobia; post-traumatic stress disorder (PTSD).” Tr. 1692. However, the ALJ determined that Plaintiff’s impairments did not meet or medically equal the severity of a listed impairment. Tr. 1693-96. At step four, the ALJ concluded that Plaintiff has the residual functional capacity to perform light work as defined in 20 C.F.R. §§ 404.1567(b) with the following limitations: [L]ifting/carrying/pushing/pulling of 20 pounds occasionally and 10 pounds or less frequently, can sit 6 hours in an 8-hour workday, can stand/walk in combination 6 hours in an 8-hour workday, except she can occasionally climb ramps and stairs, must avoid ladders, ropes, and scaffolds, can occasionally stoop, kneel, crouch, and crawl; is limited to simple and routine tasks, simple work-related decisions, occasional interaction with coworkers, supervisors, and the general public, and would be off task up to 5% of the workday.

Tr. 1696. Because of these limitations, the ALJ concluded that Plaintiff could not perform her past relevant work. Tr. 1706.
