Benign neoplasm of colon

This code signifies the presence of a non-cancerous growth originating from the cells lining the colon. These benign neoplasms, often polyps, are typically slow-growing and do not invade surrounding tissues or metastasize to distant sites. While not malignant, some types of benign colonic neoplasms have the potential to transform into cancer over time.

Assign this code when documentation confirms a benign neoplasm of the colon, such as an adenomatous polyp, hyperplastic polyp, or hamartomatous polyp, without any indication of malignancy. This code is appropriate for initial diagnosis, surveillance, or follow-up of such lesions. Supporting documentation includes pathology reports, colonoscopy findings, and physician notes explicitly stating "benign" or "non-malignant."

• Do not use this code if the pathology report indicates dysplasia of an unspecified degree or carcinoma in situ; these require more specific codes.
• Distinguish carefully between benign neoplasms and inflammatory polyps, which are coded differently.
• If the benign neoplasm is removed, ensure the operative report clearly states the site and benign nature for accurate coding of the procedure.
