Benign neoplasm of ascending colon

This code signifies a non-cancerous tumor originating in the ascending portion of the large intestine. These benign growths, often polyps, do not invade surrounding tissues or metastasize to distant sites. While generally harmless, they may have the potential for malignant transformation over time.

Use this code for documented benign neoplasms specifically located in the ascending colon, typically identified during colonoscopy or imaging studies. Documentation should clearly state "benign" and specify the ascending colon as the anatomical site. This code is appropriate when pathology confirms a non-malignant lesion.

• Ensure the documentation explicitly states "benign" and precisely identifies the "ascending colon."
• Do not use this code if the neoplasm is described as malignant, uncertain, or of unknown behavior; refer to the appropriate C-series or D37 codes.
• If the specific colon segment is not documented (e.g., "benign colon polyp"), query the provider for clarification to ensure accurate site-specific coding.
