Benign neoplasm of anus and anal canal

This code represents a non-cancerous growth originating from the tissues lining the anus or anal canal. These benign neoplasms are typically slow-growing and do not metastasize to other parts of the body. They may present as polyps, adenomas, or other non-malignant cellular proliferations within this specific anatomical region.

Use this code when documentation clearly identifies a benign neoplasm located within the anus or anal canal. This diagnosis is often established through biopsy and histopathological examination, confirming the non-malignant nature and specific anatomical site. It is appropriate for conditions like benign anal polyps or adenomas.

• Always confirm the benign nature of the neoplasm; if malignant, a C-code is appropriate.
• Carefully distinguish between the anal canal/anus and the anal margin, perianal skin, or anal skin, as these have different codes (D22.5, D23.5).
• Ensure documentation specifies the exact location to avoid confusion with benign neoplasms of the rectum (D12.8).
