Plaintiff, MEMORANDUM DECISION v.

FRANK BISIGNANO,2

Commissioner of Social Security, Defendant. I. Brenda M. (“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, pursuant to 28 U.S.C. § 636(c), to the jurisdiction of the undersigned United States 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). the Commissioner is AFFIRMED. II. Plaintiff filed an application for DIB on July 6, 2021, alleging disability commencing on April 20, 2017. (Dkt. 12-1 at 316-21.) The Commissioner denied the claims by initial determination on May 13, 2022, and upon reconsideration on December 5, 2022. (Id. at 95, 115.) Plaintiff filed a written request for a hearing on January 6, 2023. (Id. at 132.) On February 29, 2024, Administrative Law Judge Stacy Zimmerman (the “ALJ”) conducted a hearing3 and subsequently published an unfavorable decision on April 3, 2024. (Id. at 27-38, 45-77.) Plaintiff requested review of the ALJ’s decision by the Appeals Council on May 28, 2024. (Id. at 227- 28.) The Appeals Council denied Plaintiff’s request for review on September 27, 2024. (Id. at 7-10.) On that date, the ALJ’s decision became the final decision of the Commissioner. See 42 U.S.C. § 405(h). 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. Reddick v. Chater, 157 F.3d 715, 721 (9th Cir. 1998) (citing 42 U.S.C. § 423(d)(1)(A)). The impairment must

3 Plaintiff was represented by an attorney at the hearing. (Dkt. 12-1 at 47-48.) Vocational Expert John Maier (the “VE”) testified at the hearing by telephone. (Id.) substantial gainful employment that exists in the national economy. 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. 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. (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. 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. 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. 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), 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-related) and non-exertional limitations, the Grids are inapplicable and the ALJ must take the testimony of a VE. Moore v. Apfel, 216 F.3d 864, 869 (9th Cir. 2000) (citing Burkhart v. Bowen, 856 F.2d 1335, 1340 (9th Cir. 1988)). IV. The ALJ employed the five-step sequential evaluation process and concluded that Plaintiff was not disabled within the meaning of the Social Security Act. (Dkt. 12-1 at 27-38.) At step one, the ALJ found that Plaintiff had not engaged in substantial gainful activity during the period from her alleged onset date of April 20, 2017, through her date last insured of June 30, 2023. (Id. at 29.) At step two, the ALJ found that Plaintiff had the following severe impairments: cervical and lumbar degenerative disc disease (DDD) with radiculopathy; bilateral shoulder impingement syndrome; and degenerative joint disease (DJD) of the bilateral hands and the bilateral knees. (Id.) The ALJ also determined that Plaintiff had the non- severe impairments of mild degenerative changes of the feet; tendinitis of the right Achilles tendon; major depressive disorder (MDD); anxiety disorder; and attention deficit hyperactivity disorder (ADHD). (Id. at 30-31.) At step three, the ALJ determined that Plaintiff did not have an impairment or combination of impairments that met or medically equaled the severity of any of the listings in the regulations. (Id. at 32.) The ALJ assessed Plaintiff’s RFC and concluded that she “could lift and carry hour day, and sit 6 hours in an 8-hour day; could frequently balance; could occasionally climb ramps and stairs, stoop, kneel, crouch, and crawl; could not climb ladders, ropes, or scaffolds; could frequently handle, finger, and reach overhead with the arms; must avoid more than occasional exposure to extreme cold; could not be exposed to hazards such as dangerous moving machinery or unprotected heights; and could not walk on uneven terrain.” (Id. at 32 (bold omitted).) The ALJ found that Plaintiff’s “medically determinable impairments could reasonably be expected to ca
