MEMORANDUM OPINION AND ORDER Plaintiff brings this action pursuant to 42 U.S.C. § 405(g) for judicial review of the final decision of the Commissioner of the Social Security Administration denying Plaintiff’s applications for disability insurance benefits under the Social Security Act. The Commissioner has answered and filed a transcript of the administrative record (hereinafter TR. ____). The parties have consented to jurisdiction over this matter by a United States magistrate judge pursuant to 28 U.S.C. § 636(c). The parties have briefed their positions, and the matter is now at issue. Based on the Court’s review of the record and the issues presented, the Court AFFIRMS the Commissioner’s decision. I. PROCEDURAL BACKGROUND On January 27, 2023, Plaintiff filed applications for Title II disability insurance benefits and Title XVI supplemental security income, alleging that she became disabled on August 25, 2020. (TR. 68, 164-76). “These claims were denied initially on April 21, 2023, and upon reconsideration on August 1, 2023.” (TR. 11). Following a March 14, 2024 administrative hearing, an Administrative Law Judge (ALJ) issued an unfavorable decision. (TR. 11-28). The Appeals Council denied Plaintiff’s request for review. (TR. 1-

3). Thus, the decision of the ALJ became the final decision of the Commissioner. II. THE ADMINISTRATIVE DECISION The ALJ followed the five-step sequential evaluation process required by agency regulations. , 431 F.3d 729, 731 (10th Cir. 2005); 20 C.F.R. §§ 405.1520 & 416.920. At step one, the ALJ determined that Plaintiff had not engaged in substantial gainful activity since August 25, 2020, her alleged onset date. (TR. 14). At

step two, the ALJ determined Plaintiff suffered from severe disorders involving: anxiety; depression; bipolar disorder; and, post-traumatic stress disorder (PTSD). (TR. 14). At step three, the ALJ found that Plaintiff’s impairments did not meet or medically equal any of the presumptively disabling impairments listed at 20 C.F.R. Part 404, Subpart P, Appendix 1 (TR. 15-16). At step four, the ALJ concluded that Plaintiff retained the residual functional capacity (RFC)1 to:

[P]erform a full range of work at all exertional levels but with the following nonexertional limitations: can understand, remember, and carry out detailed, but not complex instructions; can occasionally interact with co- workers and supervisors, but cannot interact with the public; and, can deal with occasional changes in a routine work setting.

1 Residual functional capacity “is the most [a claimant] can still do despite [a claimant's] limitations.” 20 C.F.R. § 404.1545(a)(1). (TR. 17). With this RFC, the ALJ concluded, at step four, that Plaintiff was not disabled because she could perform her past relevant work as a bench grinder (DOT #705.684- 010). (TR. 26).

Even so, the ALJ made alternative findings at step five. At the administrative hearing, the ALJ presented the RFC limitations to a vocational expert (VE) to determine whether there were other jobs in the national economy that Plaintiff could perform. (TR. 27). Given the limitations, the VE identified three jobs from the Dictionary of Occupational Titles (DOT). (TR. 27). The ALJ then adopted the VE’s testimony and concluded that during the relevant period, Plaintiff was not disabled at step five based on her ability to

perform the identified jobs. (TR. 28). III. ISSUES PRESENTED On appeal, Plaintiff challenges the ALJ’s step-three findings and argues that the ALJ failed to account for “the combination of [Plaintiff’s] medically determinable impairments” in formulating the RFC at step four. (ECF No. 9:1-2).2

2 In her reply, Plaintiff argues that the ALJ committed error at step one by failing to acknowledge that Plaintiff separated from employment “because of poor performance . . . . due to the disability at hand.” (ECF Nos. 22:2, 22-2:1). “This Court will not address arguments raised for the first time in a reply brief.” , No. CIV-22-548-P, 2023 WL 4401101, at *7 (W.D. Okla. July 7, 2023) (collecting cases). In any event, “[b]ecause the ALJ proceeded past step one to determine whether or not Plaintiff was disabled, any error in the ALJ’s step one determination is harmless.” , No. CIV-13-1022-F, 2014 WL 4418117, at *4 (W.D. Okla. Sept. 8, 2014); , No. 20-CV-00350-SH, 2022 WL 4009509, at *4 (N.D. Okla. Sept. 2, 2022). IV. STANDARD OF REVIEW This Court reviews the Commissioner’s final decision “to determin[e] whether the Commissioner applied the correct legal standards and whether the agency’s factual

findings are supported by substantial evidence.” , 952 F.3d 1172, 1177 (10th Cir. 2020) (citation omitted). Under the “substantial evidence” standard, a court looks to an existing administrative record and asks whether it contains “sufficient evidence to support the agency’s factual determinations.” , 587 U.S. 97, 102 (2019) (citation modified). “Substantial evidence . . . is more than a mere scintilla. It means—and means

only—such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” . at 103 (citation modified). While the court considers whether the ALJ followed the applicable rules of law in weighing evidence in disability cases, the court will “neither reweigh the evidence nor substitute [its] judgment for that of the agency.” , 805 F.3d 1199, 1201 (10th Cir. 2015) (citation modified). Nevertheless, the Court must reverse decisions if the ALJ has simply picked out and relied on evidence that supports her conclusion without discussing relevant evidence to the contrary.

V. STEP THREE Plaintiff alleges the ALJ committed legal error at step three in the consideration of her mental impairments. (ECF No. 9:13-18). The Court disagrees. A. Criteria at Step Three At step three, the ALJ must determine whether the claimant’s impairment is “equivalent to one of a number of listed impairments that the Secretary acknowledged

as so severe as to preclude substantial gainful activity.” , 79 F.3d 1007, 1009 (10th Cir. 1996). If this standard is met, the claimant is considered per se disabled. , 755 F.2d 141, 146 (10th Cir. 1985). The question of whether a claimant meets or equals a listed impairment is strictly a medical determination. , 929 F.2d 534, 536 (10th Cir. 1990); 20 C.F.R. §§ 404
