Blue Book Listing 13.18

Large Intestine (Colon, Rectum, Anus)

Colorectal cancer and anal canal cancers.

What you have to prove

Meet listing via: (1) adenocarcinoma that is inoperable, unresectable, recurrent, or with metastases beyond the regional lymph nodes; OR (2) squamous cell carcinoma of the anus recurrent after surgery.

Medical evidence SSA expects

Pathology, colonoscopy reports, CEA levels, imaging (CT, PET), and treatment records.

Common misconceptions

Early-stage colon cancer resected with curative intent + adjuvant chemo often doesn't meet the listing. Stage IV or recurrent disease typically does.

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.
