    SSDIResidual Functional Capacity

    RFC

    SSA's assessment of the maximum amount of work-related physical and mental activity a person can do consistently over a full workday despite their impairments, used when a claimant does not meet a Blue Book listing.

    Physical RFC classifies work capacity as: Sedentary, Light, Medium, Heavy, or Very Heavy.

    Mental RFC assesses abilities like concentration, following instructions, and handling stress.

    At age 50+, the Medical-Vocational Grid Rules give greater weight to age, education, and work history.

    → A well-documented RFC from your treating physician can significantly strengthen your SSDI claim.
