CPT® Code 99455

CPT® Code 99455 is used to report a work-related or medical disability examination performed by the treating physician. This service involves a comprehensive evaluation to assess a patient’s degree of impairment or disability, often in the context of workers’ compensation, disability claims, or functional capacity determination.

The examination focuses on reviewing medical records, performing a detailed physical assessment, and completing required disability reports or forms that support impairment ratings or work capacity determinations.
