SERRITA S. A.,1 Case No. 8:24-cv-02563-AJR

Plaintiff, v. MEMORANDUM DECISION FRANK BISIGNANO,2 Commissioner of Social Security,

Defendant. I. Serrita S. A. (“Plaintiff”) brings this action seeking to overturn the decision of the Commissioner of Social Security (the “Commissioner” or “Defendant”) denying her application for Disability Insurance Benefits (“DIB”). The parties consented to the jurisdiction of the undersigned U.S. Magistrate Judge. (Dkts. 5, 6.) For the

1 Plaintiff’s name is partially redacted in compliance with Federal Rule of Civil Procedure 5.2(c)(2)(B) and the recommendation of the Committee on Court Administration and Case Management of the Judicial Conference of the United States. 2 Commissioner Frank Bisignano is substituted in as the Defendant in this action pursuant to Federal Rule of Civil Procedure 25(d). reasons stated below, the decision of the Commissioner is REVERSED, and this case is REMANDED with directions to award Plaintiff benefits immediately. II. On February 24, 2020, Plaintiff filed her application for DIB, alleging disability beginning on October 16, 2018. (Dkt. 10-6 at 6-9.) The Commissioner denied the claims by initial determination, (Dkt. 10-4 at 2-6), and upon reconsideration. (Id. at 28-42.) Plaintiff filed a written request for hearing on October 20, 2021. (Dkt. 10-5 at 19-20.) On April 7, 2022, Administrative Law Judge Stacy Zimmerman (the “ALJ”) conducted a hearing by telephone3 and subsequently published an unfavorable decision on April 20, 2022. (Dkt. 10-3 at 15-27, 32-53.) Plaintiff requested review of the ALJ’s decision by the Appeals Council on June 2, 2022. (Dkt. 10-5 at 92-97.) The Appeals Council denied Plaintiff’s request for review on March 30, 2023. (Dkt. 10-3 at 2-7.) On May 12, 2023, Plaintiff filed a complaint with this Court in Serrita S.A. v. Comm’r, Soc. Sec. Admin., Case No. 8:23-cv-00831-AJR. (Dkt. 10-14 at 27-29.) On January 2, 2024, this Court reversed the decision of the Commissioner and remanded on the grounds that the ALJ failed to address Social Security Ruling (“SSR”) 03-2p. (Id. at 30-40.) On March 5, 2024, the Appeals Council remanded Plaintiff’s case to an ALJ. (Id. at 43-47.) On remand, the same ALJ presided over Plaintiff’s case. (Dkt. 10-13 at 2- 49.) On August 21, 2024, the ALJ conducted a telephonic hearing and subsequently published an unfavorable decision on September 20, 2024.4 (Id.) As Plaintiff did 3 The ALJ conducted the hearing telephonically due to the COVID-19 pandemic. (Dkt. 10-3 at 15.) Plaintiff was represented by an attorney at the hearing and agreed to conduct the hearing telephonically. (Id. at 15, 34-35.) 4 Plaintiff was represented by an attorney at the hearing and agreed to conduct the hearing telephonically. (Dkt. 10-13 at 36-38.) not file written exceptions and the Appeals Council did not assume jurisdiction, the ALJ’s decision became the final decision of the Commissioner on the 61st day, November 20, 2024.5 See 42 U.S.C. § 405(g); 20 C.F.R. §§ 404.984(d), 416.1484(d). Plaintiff now seeks review of the ALJ’s final decision. To qualify for disability benefits, a claimant must demonstrate a medically determinable physical or mental impairment that prevents the claimant from engaging in substantial gainful activity and that is expected to result in death or to last for a continuous period of at least twelve months. See Reddick v. Chater, 157 F.3d 715, 721 (9th Cir. 1998) (citing 42 U.S.C. § 423(d)(1)(A)). The impairment must render the claimant incapable of performing work previously performed or any other substantial gainful employment that exists in the national economy. See Tackett v. Apfel, 180 F.3d 1094, 1098 (9th Cir. 1999) (citing 42 U.S.C. § 423(d)(2)(A)). To decide if a claimant is entitled to benefits, an ALJ conducts a five-step inquiry. See 20 C.F.R. §§ 404.1520, 416.920. The steps are: (1) Is the claimant presently engaged in substantial gainful activity? If so, the claimant is found not disabled. If not, proceed to step two. (2) Is the claimant’s impairment severe? If not, the claimant is found not disabled. If so, proceed to step three. 5 Ordinarily, an ALJ’s decision becomes the Commissioner’s “final decision” only if the Appeals Council denies review or issues its own decision. See 20 C.F.R. §§ 404.955, 404.981. However, where, as here, the case is remanded by a federal court, different rules apply. Under 20 C.F.R. §§ 404.984 and 416.1484, if the claimant does not file written exceptions to the ALJ’s decision within 60 days, and the Appeals Council does not assume jurisdiction, the ALJ’s decision automatically becomes the Commissioner’s final decision. (3) Does the claimant’s impairment meet or equal one of the specific impairments described in 20 C.F.R. Part 404, Subpart P, Appendix 1? If so, the claimant is found disabled. If not, proceed to step four. (4) Is the claimant capable of performing his past work? If so, the claimant is found not disabled. If not, proceed to step five. (5) Is the claimant able to do any other work? If not, the claimant is found disabled. If so, the claimant is found not disabled. See Tackett, 180 F.3d at 1098-99; see also Bustamante v. Massanari, 262 F.3d 949, 953-54 (9th Cir. 2001); 20 C.F.R. §§ 404.1520(b)-(g)(1), 416.920(b)-(g)(1). The claimant has the burden of proof at steps one through four and the Commissioner has the burden of proof at step five. See Bustamante, 262 F.3d at 953-54. Additionally, the ALJ has an affirmative duty to assist the claimant in developing the record at every step of the inquiry. See id. at 954. If, at step four, the claimant meets their burden of establishing an inability to perform past work, the Commissioner must show that the claimant can perform some other work that exists in “significant numbers” in the national economy, taking into account the claimant’s residual functional capacity (“RFC”), age, education, and work experience. Tackett, 180 F.3d at 1098, 1100; Reddick, 157 F.3d at 721; 20 C.F.R. §§ 404.1520(g)(1), 416.920(g)(1). The Commissioner may do so by the testimony of a vocational expert (“VE”) or by reference to the Medical-Vocational Guidelines appearing in 20 C.F.R. Part 404, Subpart P, Appendix 2 (commonly known as “the Grids”). Osenbrock v. Apfel, 240 F.3d 1157, 1162 (9th Cir. 2001). When a claimant has both exertional (strength-re
