What you have to prove
Show one of: (A) disorganization of motor function in two extremities with extreme limitation; OR (B) marked limitation in physical functioning AND marked limitation in one mental functioning area.
Medical evidence SSA expects
EMG/NCS, neurology records, underlying cause workup (diabetes, autoimmune, chemo-induced, hereditary), and functional assessments.
Common misconceptions
Diabetic neuropathy with mild numbness usually doesn't qualify. Severe demyelinating neuropathies (CIDP, GBS sequelae) with significant weakness often do.
Didn't meet the listing? You can still qualify via a Medical-Vocational
Allowance — SSA's determination that your residual functional capacity, combined with
your age, education, and work history, leaves no jobs you can do. See our
appeals guide for what to do after an initial denial.
