Benign neoplasm of colon, rectum, anus and anal canal (D12) ICD-10-CM
The D12 code range covers benign neoplasm of colon, rectum, anus and anal canal with 11 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the D12 Code Range
These benign growths occur in the colon, rectum, anus, or anal canal. A benign colon neoplasm lacks malignant features, invasion, and the potential to spread.
D12 divides the growths by location. Its subdivisions distinguish the cecum and appendix from the ascending, transverse, descending, and sigmoid colon. They also identify an unspecified part of the colon, the rectosigmoid junction, the rectum, and the anus or anal canal.
