Background

Kelee L. Y. sought Supplemental Security Income based in part on a seizure disorder. An administrative law judge found her not disabled, and the Social Security Appeals Council declined review, making that ruling the Commissioner’s final decision.

On judicial review, the parties filed competing briefs about whether the agency properly evaluated the medical record and the frequency and severity of the seizures. The claimant argued that the administrative decision understated a medically determinable impairment and failed to analyze whether her condition met or equaled the agency’s listed impairments.

The Court’s Holding

The court reversed and remanded. It found harmful error at steps two and three of the sequential disability analysis. The administrative law judge did not adequately account for evidence bearing on the seizure disorder or give a legally sufficient explanation for the conclusion that the condition was not severe and did not satisfy the relevant listing.

The court also rejected reliance on older records suggesting medication noncompliance. Those records predated the relevant benefits period and did not contradict the claimant’s testimony that she had taken prescribed medication consistently for at least three months beginning in April 2022. Because correcting the step-two and step-three analysis could change the disability determination, the court returned the matter for further agency proceedings rather than deciding the remaining objections.

Key Takeaways

  • Social Security adjudicators must evaluate medically determinable seizure impairments using evidence from the relevant claim period.
  • Older treatment notes do not constitute substantial evidence of current medication noncompliance when they do not conflict with the claimant’s later testimony.
  • An agency must explain its severity and listing conclusions well enough to permit meaningful judicial review.
  • When those errors may affect the outcome, remand for a renewed administrative analysis is appropriate.

Why It Matters

The ruling illustrates why disability practitioners should organize seizure records around the precise benefits period and address medication adherence directly. Evidence of earlier lapses cannot automatically be used to discount later testimony or current limitations.

It also reinforces that step-two and listing findings are not boxes an administrative law judge may check without analysis. A claimant is entitled to a reasoned evaluation of the medical evidence before benefits are denied.
