ICD-10 Code K63.5 – Polyp of colon (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K63.5 – Polyp of colon
What it is
K63.5 identifies a polyp in the colon, which is a growth projecting from the lining of the large intestine. It is used when the record documents a colon polyp without a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Colon polyps are often found during colonoscopy and may be asymptomatic, though some patients have rectal bleeding or a positive stool test.
When to use this code
Use K63.5 when the provider documents a polyp of the colon and no histology or more specific site is given. It also fits when a colonoscopy report confirms a colon polyp but the final pathology is not documented. If the record specifies a different intestinal site, code that site instead.
Do not use for
Do not use K63.5 for rectal polyps, anal polyps, or polyps of the stomach or small intestine. Check documentation if the lesion is described as adenomatous, inflammatory, or malignant and a more specific code is available.
Coding tip
Confirm the exact anatomic site and pathology wording before assigning K63.5.
