D12

D12 — Benign neoplasm of colon, rectum, anus and anal canal

Non-billable headerICD-10-CM

D12 is a non-billable header ICD-10-CM code for benign neoplasm of colon, rectum, anus and anal canal. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

benign carcinoid tumors of the large intestine and rectum (D3A.02-)
polyp of colon NOS (K63.5)

Other codes that can never be billed with D12

These codes carry an Excludes1 note pointing at D12. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D12 alone.

D23.5Other benign neoplasm of skin of trunk
D13.3Benign neoplasm of other and unspecified parts of small intestine
K62.1Rectal polyp

Risk adjustment

D12 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead D12

10 child codes. Green means billable.
