Other codes that can never be billed with Q85.0

These codes carry an Excludes1 note pointing at Q85.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q85.0 alone.

D33Benign neoplasm of brain and other parts of central nervous system
D36.1Benign neoplasm of peripheral nerves and autonomic nervous system
D48Neoplasm of uncertain behavior of other and unspecified sites

Q85.0 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 Q85.0

5 child codes. Green means billable.
