McKinney v. Social Security Administration, Commissioner

In McKinney v. SSA, the petitioner Sarah McKinney challenged the denial of Social Security Disability Insurance benefits, arguing that the Administrative Law Judge improperly discounted her treating physician's opinion and relied on flawed vocational expert testimony. The case reached the U.S. Court of Appeals for the Eleventh Circuit. McKinney, a former nurse from Georgia, suffered from fibromyalgia and chronic fatigue syndrome. The Appeals Council denied review, making the ALJ's decision final. McKinney filed suit in federal district court, which affirmed the denial. On appeal, she contended that the SSA's evaluation violated the treating physician rule and her due process rights. The court examined whether substantial evidence supported the ALJ's residual functional capacity assessment and whether procedural errors warranted remand. The decision provided guidance on evaluating subjective symptom testimony under new SSA rulings.

The Eleventh Circuit reversed and remanded the district court's decision, holding that the ALJ's residual functional capacity determination was not supported by substantial evidence because it failed to account for moderate limitations in maintaining concentration and pace, and the hypothetical question to the vocational expert was incomplete. The Commissioner's final decision was vacated, and the case remanded for further administrative proceedings consistent with the opinion.

The central dispute was whether the ALJ properly applied the revised SSA regulations on evaluating medical opinions for claims filed after 2017, specifically whether the treating physician’s opinion was entitled to controlling weight and whether the ALJ's reliance on a vocational expert’s testimony that ignored moderate limitations in concentration, persistence, and pace constituted reversible error under the substantial evidence standard.

The ruling reinforced the requirement that ALJs must explicitly incorporate all medically determinable impairments—including moderate mental limitations—into RFC findings and vocational expert hypotheticals. It served as a significant check on SSA’s adjudicatory process, especially for claimants with subjective pain disorders, and prompted the agency to issue additional training on symptom evaluation consistency. Advocacy groups hailed the decision as vital protection for disability claimants facing improperly narrow RFC assessments.
