Plaintiff, ORDER GRANTING PLAINTIFF’S v. MERITS BRIEF

FRANK BISIGNANO, Acting [ECF No. 16] Commissioner of Social Security, Defendant. On January 7, 2025, plaintiff Daniel D. (“Plaintiff”) filed a complaint pursuant to 42 U.S.C. § 405(g) seeking judicial review of a decision by the Commissioner of Social Security (the “Commissioner”) denying his application for supplemental security income (“SSI”) benefits. (ECF No. 1.) On March 10, 2025, the Commissioner filed the Administrative Record. (ECF No. 10.) Before the Court and ready for decision is Plaintiff’s merits brief. (ECF No. 16.) The Commissioner filed an opposition (ECF No. 17), and Plaintiff filed a reply (ECF No. 18). For the reasons set forth herein, the Court GRANTS Plaintiff’s merits brief, reverses the decision of the Commissioner, and remands this matter for further administrative proceedings pursuant to sentence four of 42 U.S.C. § 405(g). On or about June 25, 2021, Plaintiff filed an application for SSI under Title XVI of the Social Security Act, alleging disability beginning January 1, 2005. (Certified Administrative Record [“AR”], at 22, 268–90.) After his application was denied initially and upon reconsideration (AR 140–44, 164–69), Plaintiff requested an administrative hearing before an administrative law judge (“ALJ”) (AR 170–87). An administrative hearing was held on February 15, 2024. (AR 41–66.) Plaintiff appeared at the hearing with a non-attorney representative, and testimony was taken from him, as well as from a vocational expert (“VE”). (AR 41–66.) As reflected in his April 17, 2024, hearing decision, the ALJ found that Plaintiff would not be disabled if he stopped his substance abuse, and therefore, Plaintiff had not been disabled within the meaning of the Social Security Act at any time from the application date through the date of decision. (AR 19–40.) The ALJ’s decision became the final decision of the Commissioner on December 11, 2024, when the Appeals Council denied Plaintiff’s request for review. (AR 6–11.) This timely civil action followed. In rendering his decision, the ALJ followed the Commissioner’s five-step sequential evaluation process under 20 C.F.R. § 416.920(a). (AR 23.) The ALJ also considered Plaintiff’s substance use disorder pursuant to 20 C.F.R. § 416.935. (AR 24.) At step one, the ALJ found that Plaintiff had not engaged in substantial gainful activity since June 25, 2021, the application date. (AR 24.) At step two, the ALJ found that Plaintiff has the following severe impairments: generalized anxiety disorder, post-traumatic stress disorder (“PTSD”), neurocognitive impairment, depression, chronic venous insufficiency, obesity, alcohol use disorder, and marijuana use disorder. (AR 24.) /// At step three, the ALJ found that with the inclusion of Plaintiff’s substance use, the severity of his claimed mental impairments meets the criteria of section 12.06 of the Commissioner’s Listing of Impairments. (AR 25.) The ALJ then determined that if Plaintiff stopped his substance use, the remaining limitations would still cause more than a minimal impact on his ability to perform basic work activities; therefore, Plaintiff would have a severe impairment or combination of impairments under 20 C.F.R. § 416.922. (AR 26–27.) However, the ALJ further found that if Plaintiff stopped the substance use, he would not have an impairment or combination of impairments that meets or medically equals the severity of one of the impairments listed in the Commissioner’s Listing of Impairments. (AR 27–29.)1 Next, the ALJ determined that, if Plaintiff stopped the substance use, he had the residual functional capacity (“RFC”) “to perform light work” with the following limitations: 1 Pursuant to the Social Security Act, if the Social Security Administration (“SSA”) finds that a claimant is disabled and has medical evidence of his drug addiction or alcoholism, it “must determine whether [the claimant’s] drug addiction or alcoholism is a contributing factor material to the determination of disability[.]” 20 C.F.R. § 416.935(a); see also SSR 13-2P, 2013 WL 621536, at *4 (Feb. 20, 2013). The “key factor” the SSA will examine “in determining whether drug addiction or alcoholism is a contributing factor material to the determination of disability is whether [the SSA] would still find [the claimant] disabled if [he] stopped using drugs or alcohol.” 20 C.F.R. § 416.935(b)(1). “In making this determination, [the SSA] will evaluate which of [the claimant’s] current physical and mental limitations, upon which [the SSA] based [its] current disability determination, would remain if [the claimant] stopped using drugs or alcohol and then determine whether any or all of [the claimant’s] remaining limitations would be disabling.” Id. § 416.935(b)(2). If the SSA determines that the claimant’s “remaining limitations would not be disabling, [it] will find that [the claimant’s] drug addiction or alcoholism is a contributing factor material to the determination of disability.” Id. § 416.935(b)(3). However, if the SSA determines that the claimant’s “remaining limitations are disabling, [the claimant is] disabled independent of [his] drug addiction or alcoholism and [the SSA] will find that [the claimant’s] drug addiction or alcoholism is not a contributing factor frequently climb ramps and stairs; occasionally climb ladders, ropes, and scaffolds; frequently balance, stoop, kneel, crouch, and crawl; understand, remember, and carry out simple, routine, repetitive tasks, with breaks every two hours; no interaction with the general public; occasional work-related, non-personal, non-social interaction with co-workers and supervisors involving no more than a brief exchange of information or handoff of product. Cannot perform highly time pressured tasks such that the claimant is limited to generally goal-oriented work, not time sensitive strict production quotas (i.e., production rate pace work with strict by the minute or by the hour production quotas that are frequently and/or constantly monitored by supervisors or that are fast paced); low-stress environment where there are few work place changes (i.e., the claimant would not have to switch from task to task) and the claimant has minimal decision-making capability (i.e., he would be unable to exercise substantial discretion in carrying out work activities). (AR 29.) For purposes of his step four determination, the ALJ determined that Plaintiff has no past relevant work. (AR 34.) At step five, based on the VE’s testimony that a hypothetical person with Plaintiff’s vocational profile and RFC, if he stopped the substance use, could perform the requirements of occupations that existed in significant numbers in the national economy (e.g., inspector, hand packager, and sub-assembler), the ALJ found that Plaintiff was not disabled under the law from the application date, through the date of decision. (AR 34– 35.) As reflected in Plaintiff’s merits brief, the disputed issues that Plaintiff is raising as the grounds for reversal and remand are as follows: 1. The ALJ failed to properly evaluate the medical opinions of Dr Fabiola Del Aguila (“Dr. Aguila”), Plaintiff’s treating psychologist, and Arthur Roehr, DNP, PMHNP- BC (“DNP Roehr”
