M90
M90 — Osteopathies in diseases classified elsewhere
Non-billable headerICD-10-CM
M90 is a non-billable header ICD-10-CM code for osteopathies in diseases classified elsewhere. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Other codes that can never be billed with M90
These codes carry an Excludes1 note pointing at M90. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M90 alone.
Risk adjustment
M90 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 M90
3 child codes. Green means billable.
