ICD-10 Code K62.1 – Rectal Polyp (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K62.1 – Rectal polyp
What it is
K62.1 identifies a polyp located in the rectum. Use it when the record documents a rectal mucosal growth or polyp, without a more specific histology or alternate diagnosis.
Clinical signs
Rectal polyps may be found during endoscopy, digital rectal examination, or imaging, and may cause bleeding or be asymptomatic. Clinical features vary; refer to documentation.
When to use this code
Use K62.1 when the clinician documents a rectal polyp and no more specific code is available. It fits cases where the lesion is in the rectum but pathology details are absent or not coded separately. If the note identifies a different anorectal condition, check documentation.
Do not use for
Do not use K62.1 for polyps in the colon, anal canal, or unspecified gastrointestinal sites. Check documentation if the record describes a neoplasm, inflammatory lesion, or another rectal disorder.
Coding tip
Confirm the anatomic site first; code the rectum only when the documentation clearly places the polyp there.
