LADY M.1, No. 4:25-CV-05128-RLP

Plaintiff, ORDER REVERSING AND REMANDING THE v. COMMISSIONER’S DECISION FOR FURTHER ADMINISTRATIVE COMMISSIONER OF SOCIAL

Defendant.

BEFORE THE COURT is an appeal from an Administrative Law Judge (ALJ) final decision denying supplemental security income under Title XVI of the Social Security Act. ECF No. 12. The Court considered the matter without oral argument. For the reasons discussed below, the Court concludes the ALJ committed harmful legal error in assessing whether Ms. M. met or medically equaled a Listing and in evaluating Ms. M.’s symptom testimony. Therefore, Ms.

1 Plaintiff’s first name and last initial are used to protect her privacy. M.’s brief, ECF No. 12, is granted and the Commissioner’s brief, ECF No. 16, is denied.

Ms. M. was seven years old on the alleged onset date of May 1, 2008. Tr. 201. Ms. M. graduated from a special education high school. Tr. 46. She briefly

worked at Goodwill and Wal-Mart in 2019 and 2020 respectively. Tr. 212-13. She has no other work history. Tr. 208-14. Ms. M. filed this claim for supplemental security income on April 1, 2022. Tr. 201-06. The claim was denied initially and upon reconsideration. Tr. 63-72, 74-

82. A hearing occurred on January 16, 2025, at which Ms. M. testified as to her symptoms. Tr. 39-62. On January 29, 2025, the ALJ issued an unfavorable decision. Tr. 17-29. The Appeals Council denied a request for review. Tr. 1-3. The

matter is now before this Court pursuant to 42 U.S.C. § 405(g). This Court’s review of a final decision of the Commissioner of Social Security is governed by 42 U.S.C. § 405(g). The scope of review is limited; the

Commissioner’s decision will be disturbed “only if it is not supported by substantial evidence or is based on legal error.” Hill v. Astrue, 698 F.3d 1153, 1158 (9th Cir. 2012). If the evidence in the record “is susceptible to more than one

rational interpretation, [the Court] must uphold the ALJ’s findings if they are supported by inferences reasonably drawn from the record.” Molina v. Astrue, 674

F.3d 1104, 1111 (9th Cir. 2012). Further, a district court “may not reverse an ALJ’s decision on account of an error that is harmless.” Id. An error is harmless “where it is inconsequential to the

[ALJ’s] ultimate nondisability determination.” Id. at 1115 (quotation and citation omitted). The party appealing the ALJ’s decision generally bears the burden of establishing that it was harmed. Shinseki v. Sanders, 556 U.S. 396, 409-10, 129 S. Ct. 1696 (2009).

A claimant must satisfy two conditions to be considered “disabled” within the meaning of the Social Security Act. First, the claimant must be “unable to

engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than twelve months.” 42 U.S.C. §§ 423(d)(1)(A), 1382c(a)(3)(A). Second, the claimant’s

impairment must be “of such severity that he is not only unable to do [his or her] previous work[,] but cannot, considering [his or her] age, education, and work experience, engage in any other kind of substantial gainful work which exists in

the national economy.” 42 U.S.C. §§ 423(d)(2)(A), 1382c(a)(3(B). The Commissioner has established a five-step sequential analysis to determine whether a claimant satisfies the above criteria. See 20 C.F.R. §

416.920(a)(4)(i)-(v). At step one, if the claimant is engaged in “substantial gainful activity,” the Commissioner must find that the claimant is not disabled. 20 C.F.R. § 416.920(b). At step two, the Commissioner considers the severity of the claimant’s

impairment. 20 C.F.R. § 416.920(a)(4)(ii). If the claimant suffers from “any impairment or combination of impairments which significantly limits [his or her] physical or mental ability to do basic work activities,” the analysis proceeds to step three. 20 C.F.R. § 416.920(c). At step three, the Commissioner compares the

claimant’s impairment to severe impairments recognized by the Commissioner to be so severe as to preclude a person from engaging in substantial gainful activity. 20 C.F.R. § 416.920(a)(4)(iii).

If the severity of the claimant’s impairment does not meet or exceed the severity of the enumerated impairments, the Commissioner must assess the claimant’s residual functional capacity (RFC), which is the claimant’s ability to perform physical and mental work activities on a sustained basis despite his or her

limitations, 20 C.F.R. § 416.945(a)(1). At step four, the Commissioner considers whether, in view of the claimant’s RFC, the claimant is capable of performing work that he or she has performed in

the past (past relevant work). 20 C.F.R. § 416.920(a)(4)(iv). If not, the analysis proceeds to step five and the Commissioner considers whether, in view of the claimant’s RFC, the claimant is capable of performing other work in the national

economy. 20 C.F.R. § 416.920(a)(4)(v). The claimant bears the burden of proof at steps one through four above. Tackett v. Apfel, 180 F.3d 1094, 1098 (9th Cir. 1999). If the analysis proceeds to

step five, the burden shifts to the Commissioner to establish that (1) the claimant is capable of performing other work; and (2) such work “exists in significant numbers in the national economy.” 20 C.F.R. § 416.960(c)(2); Beltran v. Astrue, 700 F.3d 386, 389 (9th Cir. 2012).

At step one, the ALJ found Ms. M. had not engaged in substantial gainful activity since April 6, 2022. Tr. 19. At step two, the ALJ found Ms. M. had the

following severe impairments: Major Depressive Disorder, ADHD, Autism Spectrum Disorder, and Mild obesity. Id. At step three, the ALJ found Ms. M. did not have an impairment or combination of impairments that met or medically equaled the severity of a listing.

Tr. 21. Specifically, the ALJ considered Listings 12.04 Depressive, Bipolar and Related Disorders, 12.10 Autism Spectrum Disorder, and 12.11 Neurodevelopmental Disorders. Id. The ALJ found Ms. M. did not satisfy the B

Criteria for these listings because she had only mild limitations in her ability to understand, remember, or apply information, and adapting and managing herself. Tr. 21-22. The ALJ found moderate limitations in her ability to interact with
