Robert Michael Lesko v. Commissioner, Social Security Administration

Summary

The United States District Court for the Western District of Pennsylvania reviewed cross-motions for summary judgment in a Social Security disability benefits appeal. The court held that the ALJ failed to adequately explain how the claimant's mild mental limitations, including fatigue, brain fog, and concentration symptoms, were reflected in the residual functional capacity assessment. The claimant's motion was granted, the Commissioner's motion was denied, and the decision denying benefits was vacated and remanded under sentence four of 42 U.S.C. § 405(g).

Holdings

1. An ALJ must consider all medically determinable impairments, including nonsevere impairments producing only mild mental limitations, when formulating the claimant's RFC.
2. An ALJ may not rely on a finding of mild mental limitations while omitting any explanation of their impact on the RFC and vocational-expert hypothetical.
3. The case must be remanded for the ALJ to consider Lesko's mild mental limitations in formulating the RFC; the court need not reach the remaining challenges because the ALJ may reach different conclusions on remand.

Questions Presented

1. Whether the ALJ's residual functional capacity assessment was supported by substantial evidence when the ALJ found mild mental limitations related to fatigue, memory, concentration, and brain fog but did not explain how those limitations affected the RFC.
2. Whether remand was required because the ALJ failed to include or adequately convey the claimant's mild mental limitations in the vocational-expert hypothetical and failed to provide a detailed assessment of those limitations.
3. Whether the court should reach Lesko's additional arguments concerning the ALJ's evaluation of the medical evidence, subjective symptoms, and treating-source opinions.
