Tibbetts v. Kijakazi

Background

Michael Tibbetts challenged an administrative law judge’s denial of his application for Social Security disability benefits under Titles II and XVI of the Social Security Act. The administrative law judge found that Tibbetts had several severe impairments, including right wrist radial motor palsy, left knee degenerative joint disease, obesity, and anxiety disorder. The judge also found mild limitations in understanding, remembering, or applying information and moderate limitations in concentrating, persisting, or maintaining pace.

The administrative law judge assessed Tibbetts’s residual functional capacity—the most he could still do despite his impairments—as medium work with specified physical and mental limitations. The assessment stated, among other things, that Tibbetts could understand complex tasks and maintain attention to job duties for 95 percent of the workday. Based on that assessment, the judge concluded that Tibbetts could perform his past relevant work as a plasterer and was not disabled.

Parties’ Arguments

Tibbetts argued that the administrative law judge failed to address the mild and moderate mental impairments that the judge had found when formulating the residual functional capacity. Tibbetts did not argue that the judge necessarily had to include corresponding limitations in the assessment. Instead, he argued that the judge had to explain how those mental limitations affected his ability to perform his past relevant skilled work.

The Commissioner responded that the administrative law judge had accommodated Tibbetts’s mental limitations by finding that he could maintain attention to job duties for 95 percent of the workday.

Court’s Analysis

The court explained that an administrative law judge must consider all medically determinable impairments, including impairments that are not severe, when determining residual functional capacity. Although the administrative law judge stated that the assessment reflected the mental-function findings and included an attention-related limitation, the judge did not directly address Tibbetts’s mild and moderate mental impairments in the residual-functional-capacity analysis.

The court also noted that the administrative law judge had found persuasive the opinion of Dr. Ute Kollath. That opinion described impairments in Tibbetts’s ability to maintain adequate pace or persistence for complex tasks, follow complex or detailed instructions, and maintain adequate attention or concentration. Because the administrative law judge did not explain how Tibbetts’s mental impairments were accounted for, the court could not determine whether the judge had fulfilled the obligation to consider them.

The court concluded that the error was not harmless. It could not say that the error was inconsequential to the ultimate decision denying benefits. Because this error alone required further proceedings, the court did not address Tibbetts’s other arguments.

Disposition

The court granted Tibbetts’s motion for summary judgment and denied the Commissioner’s cross-motion. It vacated the administrative law judge’s decision denying benefits and remanded the case to the Social Security Administration for further consideration consistent with the order. The order did not award benefits to Tibbetts.
