Blue Book Listing 1.18

Abnormality of a Major Joint (Hip, Knee, Ankle, Shoulder, Elbow, Wrist)

Chronic joint damage that prevents effective ambulation or fine/gross manipulation.

What you have to prove

Show: (1) imaging-confirmed anatomical abnormality of the joint; (2) chronic pain, stiffness, or instability; (3) a finding on physical exam of limited range of motion; and (4) inability to ambulate effectively (weight-bearing joints) OR inability to perform fine and gross movements effectively (upper extremities).

Medical evidence SSA expects

X-ray or MRI of the joint, surgical records (arthroplasty, arthroscopy), physical therapy notes, and physician documentation of assistive-device need.

Common misconceptions

A single joint problem rarely qualifies on its own — most approvals come when multiple joints are involved or when combined with other impairments in a Medical-Vocational Allowance.

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.
