M16
M16 — Osteoarthritis of hip
Non-billable headerICD-10-CM
M16 is a non-billable header ICD-10-CM code for osteoarthritis of hip. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with M16
These codes carry an Excludes1 note pointing at M16. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M16 alone.
Risk adjustment
M16 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 M16
