Defendant. _____________________________________________________________________

ORDER _____________________________________________________________________ ENTERED BY MAGISTRATE JUDGE KATHRYN A. STARNELLA

This matter is before the Court on the Social Security Administrative Record [#7], filed March 21, 2025, in support of Plaintiff’s Complaint [#1] seeking review of the decision of the Social Security Administration’s Commissioner (“Defendant” or “Commissioner”), denying Plaintiff’s claim for social security disability insurance pursuant to Title II of the Social Security Act (the “Act”), 42 U.S.C. § 401 et seq. Plaintiff filed an Opening Brief [#9] (the “Brief”), Defendant filed a Response [#10] in opposition, and Plaintiff filed a Reply [#15]. The Court has jurisdiction to review the Commissioner’s final decision under 42 U.S.C. §§ 405(g) and 1383(c)(3). The Court has reviewed the entire

1 Pursuant to D.C.COLO.LAPR 5.2(b), “[a]n order resolving a social security appeal on the merits shall identify the plaintiff by initials only.”

2 Frank Bisignano is the current Commissioner of Social Security and is substituted for former Acting Commissioner Leland Dudek as Defendant in this case. See Fed. R. Civ. P. 25(d). case file and the applicable law. For the reasons set forth below, the decision of the Commissioner is AFFIRMED.3 I. Background

On July 13, 2021, Plaintiff filed an application for disability and disability insurance benefits under Title II. Tr. 33.4 Plaintiff alleged disability beginning January 12, 2020. Id. His claim was denied on December 28, 2022, and again upon reconsideration on September 18, 2023. Id. On April 25, 2024, an administrative law judge (ALJ) issued an unfavorable decision. Tr. 30-48. On October 7, 2024, the Appeals Council denied Plaintiff's request for review. Tr. 17-19. The ALJ first determined that Plaintiff met the Act's insured status requirements through September 30, 2022, and that he did not engage in substantial gainful activity from January 12, 2020, the alleged onset date, through September 30, 2022, his date last insured. Tr. 35. The ALJ then found that, through his date last insured, Plaintiff suffered from the following severe impairments: (1) coronary artery disease/status-post coronary

artery bypass graft, (2) status-post cerebral vascular accident, (3) degenerative disc disease of the lumbar and cervical spine, and (4) osteoarthritis of the left wrist. Tr. 36. The ALJ also found Plaintiff's impairments, either separately or in combination, did not meet or medically equal “the severity of one of the listed impairments in 20 CFR Part 404, Subpart P, Appendix 1 (20 CFR 404.1520(d), 404.1525 and 404.1526).” Tr. 38.

3 The parties consented to proceed before the undersigned for all proceedings pursuant to 28 U.S.C. § 636(c) and D.C.COLO.LCivR 72.2. See Consent [#8]; Reassignment [#12].

4 The Court refers to the Transcript of the Administrative Proceedings, located at Docket No. 7, by the sequential transcript numbers instead of the separate docket numbers. The ALJ next concluded that Plaintiff had the residual functional capacity (“RFC”) to perform light work,5 including lifting and carrying up to 20 pounds occasionally and 10 pounds frequently, sitting up to six hours and standing and walking up to four hours in an eight- hour day, pushing and pulling as much as lifting and carrying, but is limited to occasional climbing of ramps and stairs, never climbing ladders or scaffolds, and occasional balancing, stooping, kneeling, crouching and crawling. Claimant is also limited to frequent handling with the left hand. Claimant is further limited to occasional exposure to extreme cold, extreme heat, dust, odors, fumes, pulmonary irritants, and no exposure to unprotected heights or moving mechanical parts.

Tr. 39. Based on the RFC and the testimony of an impartial vocational expert, the ALJ found that, through his date last insured, Plaintiff could perform his relevant past work as a programmer. Tr. 47-48. Therefore, the ALJ found that Plaintiff was not disabled at step four. Id. The ALJ’s decision is the Commissioner’s final decision for purposes of judicial review. 20 C.F.R. § 404.981 (explaining that the ALJ’s decision becomes the final decision when the Appeals Council denies a request for review). II. Standard of Review and Applicable Law

Pursuant to the Act: [T]he Social Security Administration (SSA) is authorized to pay disability insurance benefits and Supplemental Security Income to persons who have a “disability.” A person qualifies as disabled, and thereby eligible for such benefits, “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,

5 “Light work” is defined as follows: “Light work involves lifting no more than 20 pounds at a time with frequent lifting or carrying of objects weighing up to 10 pounds. Even though the weight lifted may be very little, a job is in this category when it requires a good deal of walking or standing, or when it involves sitting most of the time with some pushing and pulling of arm or leg controls. To be considered capable of performing a full or wide range of light work, you must have the ability to do substantially all of these activities. If someone can do light work, we determine that he or she can also do sedentary work, unless there are additional limiting factors such as loss of fine dexterity or inability to sit for long periods of time.” 20 C.F.R. § 404.1567(b). considering his age, education, and work experience, engage in any other kind of substantial gainful work which exists in the national economy.”

Barnhart v. Thomas, 540 U.S. 20, 21-22 (2003) (quoting 42 U.S.C. §§ 423(d)(2)(A), 1382c(a)(3)(B)). Under the applicable legal standard, a claimant is disabled if he or she is unable “to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment . . . which has lasted or can be expected to last for a continuous period of not less than 12 months.” 42 U.S.C. § 423(d)(1)(a). The existence of a qualifying disabling impairment must be demonstrated by “medically acceptable clinical and laboratory diagnostic” findings. 42 U.S.C. §§ 423(d)(3), 423(d)(5)(A).
