Anal polyp

This code identifies the presence of a benign growth or mass arising from the lining of the anal canal. These polyps are typically non-cancerous but may cause symptoms such as bleeding, pain, or a feeling of a mass. They are distinct from polyps found higher in the colorectal tract.

Use this code when documentation explicitly states "anal polyp" or describes a benign polypoid lesion located specifically within the anal canal. This diagnosis is often made during an anoscopic or proctoscopic examination. Supporting documentation should clearly indicate the anatomical location as anal.

• Differentiate from rectal polyps (K62.1) or other colorectal polyps (e.g., K63.5) based on precise anatomical documentation.
• Do not use this code for malignant anal neoplasms; instead, refer to the C codes for anal cancer.
• If the polyp is excised, ensure the pathology report confirms its benign nature to support this diagnosis code.
