TABITHA GUYER, : NO. 1:25-CV-00425 Plaintiff, : : v. : : (CAMONI, M.J.) FRANK BISIGNANO, : Commissioner of Social Security, : Defendant. :

MEMORANDUM OPINION

Plaintiff Tabitha Guyer brought this action under 42 U.S.C. § 1383(c)(3), seeking judicial review of the final decision of the Commissioner of Social Security denying her claim for disability insurance benefits under Title II of the Social Security Act. Transcript, doc. 9-3 at 2. She challenges the Administrative Law Judge’s (ALJ) assessment of the residual functional capacity. Pl.’s Br., doc 16 at 1. Because the ALJ’s determinations are supported by substantial evidence, the Court will affirm the decision of the Commissioner. I. BACKGROUND

A. Procedural History

On June 8, 2021, Guyer applied for disability benefits under Title II of the Social Security Act, alleging disability as of May 10, 2021. Doc. 9-3 at 2. Following an initial denial, Guyer submitted an appeal, requesting a hearing before an ALJ. Doc. 9-4 at 113. The ALJ conducted

the hearing and determined that Guyer was not disabled. Doc. 9-2 at 31. Guyer filed a request for review of the ALJ’s decision, which the Appeals Council denied. Id. at 2. The ALJ’s decision, therefore, became

the final decision of the Commissioner. 42 U.S.C. § 405(g); see doc. 9-8 at 3. Pending before this Court is Guyer’s action seeking judicial review of

the Commissioner’s decision. Complaint, doc. 1. This case is fully briefed (docs. 16, 18, 21) and ripe for resolution. The parties consented to the jurisdiction of a United States Magistrate Judge to conduct all

proceedings in this case, pursuant to 28 U.S.C. § 636(c) and Federal Rule of Civil Procedure 73, including entry of final judgment. Doc. 7. B. The Disability Determination Process

To determine whether a claimant is disabled under the Social Security Act, an ALJ applies a “five-step sequential evaluation process.” 20 C.F.R. § 404.1520(a)(4). The ALJ assesses whether the claimant:

1. has engaged in substantial gainful activity since the onset of the alleged disability; 2. had a severe medically determinable impairment; 3. suffered from an impairment listed in the regulations as presumptively disabling; 4. could return to his past work; and 5. could perform other available work in the national economy.

See § 404.1520(a)(4)(i)–(v).

Between steps three and four, the ALJ also determines whether the claimant’s RFC allows the claimant to continue his previous employment. § 404.1520(a)(4)(iv). RFC “is the most [a claimant] can still do despite” impairments. § 404.1545(a)(1). The claimant bears the burden of persuasion through step four, while at step five, the burden shifts to the Secretary to show that the claimant can perform substantial gainful

employment other than the claimant’s past relevant work. Williams v. Sullivan, 970 F.2d 1178, 1181 (3d Cir. 1992), citing Bowen v. Yuckert, 482 U.S. 137, 146 n.5 (1987).

C. Issues on Appeal

After following the five-step sequential analysis, the ALJ determined that Guyer “has not been under a disability . . . from May 10, 2021, through the date of this decision.” Doc. 9-2 at 31. The ALJ determined at the RFC stage that Guyer has the ability: to perform light work as defined in 20 CFR 404.1567(b) except the claimant can stand and/or walk for four (4) hours in an eight (8) hour workday. The claimant can frequently handle and finger with her non-dominant, left upper extremity. She can occasionally climb ramps or stairs, but never climb ladders, ropes or scaffolds. The claimant can occasionally balance, stoop, kneel, crouch or crawl. She can tolerate occasional exposure to unprotected heights, and she can occasionally operate hazardous machinery. The claimant can tolerate frequent exposure to extreme cold and vibrations.

Id. at 27. The ALJ denied Guyer’s disability claim at step five, after considering her “age, education, work experience, and residual functional capacity,” because he found that “there are jobs that exist in significant numbers in the national economy that the claimant can perform.” Id. at 30. On appeal, Guyer argues that the ALJ erred by: (1) failing to develop the evidentiary record; (2) failing to address her need to lie down; and (3) failing to evaluate her symptoms. Doc. 16 at 1. The Court, adhering to the deferential standard of review outlined below, will affirm

the decision of the Commissioner. II. LEGAL STANDARD In reviewing the Commissioner’s final decision denying a claimant’s

application for benefits, the Court is limited to determining whether the findings of the final decision-maker are supported by substantial evidence in the record. See 42 U.S.C. § 1383(c)(3) (incorporating 42 U.S.C. § 405(g) by reference); Johnson v. Comm’r of Soc. Sec., 529 F.3d 198, 200 (3d Cir. 2008); Ficca v. Astrue, 901 F. Supp. 2d 533, 536 (M.D.

Pa. 2012). Under the substantial-evidence standard, a court examines an existing administrative record and asks whether it contains sufficient evidence to support the agency’s factual determinations. Biestek v.

Berryhill, 587 U.S. 97, 102 (2019). Substantial evidence does not mean a large or considerable amount of evidence, but rather “such relevant

evidence as a reasonable mind might accept as adequate to support a conclusion.” Id. at 103; see also Pierce v. Underwood, 487 U.S. 552, 565 (1988). Substantial evidence is less than a preponderance of the evidence

but more than a mere scintilla. Richardson v. Perales, 402 U.S. 389, 401 (1971). A single piece of evidence is not substantial evidence if the ALJ ignores countervailing evidence or fails to resolve a conflict created by

the evidence. Mason v. Shalala, 994 F.2d 1058, 1064 (3d Cir. 1993). In an adequately developed factual record, however, substantial evidence may be “something less than the weight of the evidence, and the possibility of

drawing two inconsistent conclusions from the evidence does not prevent [the ALJ’s decision] from being supported by substantial evidence.” Consolo v. Fed. Mar. Comm’n, 383 U.S. 607, 620 (1966). “In determining if the Commissioner’s decision is supported by substantial evidence the court must scrutinize the record as a whole.” Leslie v.
