KASANDRA J. GREENE, ) ) Plaintiff, ) ) v. ) Case No. 4:25-cv-00719-SRC ) FRANK J. BISIGNANO, ) Commissioner of the Social Security ) Administration, ) ) Defendant. )

Memorandum and Order Kasandra Greene seeks judicial review, under 42 U.S.C. § 405(g), of the Commissioner of Social Security’s final decision denying her protective application for a period of disability and disability insurance benefits under Title II of the Social Security Act. As discussed below, the Court affirms the Commissioner’s decision. I. Procedural history In 2023, Greene protectively filed an application for a period of disability and disability insurance benefits. Doc. 1 at 1; Tr. 185–86 (while Greene’s opening brief mentions “supplemental security income,” doc. 10 at 1, the Court treats this mention as a typo, because the brief does not otherwise discuss supplemental security income, see id. at 3–5, 11 (citing part 404 of Title 20 of the Code of Federal Regulations, which concerns disability insurance), and neither do her Complaint, see generally doc. 1, or the administrative record, see Tr. 184–86 (selecting “no” when asked about an intent to apply for supplemental security income and applying instead for a period of disability and disability insurance benefits)). The Social Security Administration denied her application on initial review, Tr. 95–103, and on reconsideration, Tr. 108–14. Upon Greene’s request, Tr. 115–16, an Administrative Law Judge held a hearing, Tr. 31–64. Greene testified during the hearing. Tr. 39–59. Following the hearing, the ALJ denied Greene’s application. Tr. 11–26. Greene then sought review of the ALJ’s decision by the Appeals Council, but it denied Greene’s request. Tr. 1–3. The ALJ’s decision, therefore, is the final

decision of the Commissioner that this Court reviews. See 20 C.F.R. §§ 404.900(a)(5), 416.1400(a)(5). II. Standard for determining disability under the Act Under the Act, an adult individual is disabled “if he is 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. § 1382c(a)(3)(A). A claimant has a disability “only if his physical or mental impairment or impairments are of such severity that he is not only unable to do his previous work but cannot, considering his age, education, and work experience, engage in any other kind of substantial gainful work which exists in the national economy.” 42

U.S.C. § 1382c(a)(3)(B). The Commissioner follows a five-step evaluation when evaluating whether the claimant has a disability. 20 C.F.R. § 404.1520(a)(1). First, the Commissioner considers the claimant’s work activity. 20 C.F.R. § 404.1520(a)(4)(i). If the claimant is engaged in substantial gainful activity, the claimant is not disabled. Id. Second, if the claimant is not engaged in substantial gainful activity, the Commissioner evaluates the evidence to determine whether the claimant has a severe “impairment[] . . . [that] significantly limits [the claimant’s] physical or mental ability to do basic work activities.” 20 C.F.R. § 404.1520(c)). “An impairment is not severe if it amounts only to a slight abnormality

that would not significantly limit the claimant’s physical or mental ability to do basic work activities.” Kirby v. Astrue, 500 F.3d 705, 707 (8th Cir. 2007) (first citing Bowen v. Yuckert, 482 U.S. 137, 153 (1987); then citing id. at 158 (O’Connor, J., concurring); and then citing 20 C.F.R. § 404.1521(a)). Third, if the claimant has a severe impairment, the Commissioner considers the

impairment’s medical severity. 20 C.F.R. § 404.1520(a)(4)(iii). If the impairment meets or equals one of the presumptively disabling impairments listed in the regulations, the claimant is considered disabled, regardless of age, education, and work experience. 20 C.F.R. § 404.1520(a)(4)(iii), (d). Fourth, if the claimant’s impairment is severe, but it does not meet or equal one of the presumptively disabling impairments, the Commissioner assesses whether the claimant retains the residual functional capacity (RFC) to perform his or her past relevant work. 20 C.F.R. § 404.1520(a)(4)(iv). “RFC is defined as the most a claimant can still do despite his or her physical or mental limitations.” Martise v. Astrue, 641 F.3d 909, 923 (8th Cir. 2011) (quoting Leckenby v. Astrue, 487 F.3d 626, 631 n.5 (8th Cir. 2007)). While RFC must be “based on all

relevant evidence, including the medical records, observations of treating physicians and others, and an individual’s own description of his limitations,” RFC is nonetheless an administrative assessment—not a medical assessment—and therefore “it is the responsibility of the ALJ, not a physician, to determine a claimant’s RFC.” Boyd v. Colvin, 831 F.3d 1015, 1020 (8th Cir. 2016) (quoting Moore v. Astrue, 572 F.3d 520, 523 (8th Cir. 2009)). Thus, “there is no requirement that an RFC finding be supported by a specific medical opinion.” Hensley v. Colvin, 829 F.3d 926, 932 (8th Cir. 2016) (first citing Myers v. Colvin, 721 F.3d 521, 526–27 (8th Cir. 2013); and then citing Perks v. Astrue, 687 F.3d 1086, 1092–93 (8th Cir. 2012)). Ultimately, the claimant is responsible for providing evidence relating to his or her RFC,

and the Commissioner is responsible for developing the claimant’s “complete medical history, including arranging for a consultative examination[] if necessary, and making every reasonable effort to help [the claimant] get medical reports from [the claimant’s] own medical sources.” 20 C.F.R. § 404.1545(a)(3). If the Commissioner determines that the claimant retains the RFC to perform past relevant work, he or she is not disabled. 20 C.F.R. § 404.1520(a)(4)(iv).
