Other codes that can never be billed with D22

These codes carry an Excludes1 note pointing at D22. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D22 alone.

D14.0Benign neoplasm of middle ear, nasal cavity and accessory sinuses
D31Benign neoplasm of eye and adnexa
D10.0Benign neoplasm of lip
D12.9Benign neoplasm of anus and anal canal
I78.1Nevus, non-neoplastic

D22 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 D22

9 child codes. Green means billable.
