M93 — Other osteochondropathies
Non-billable headerICD-10-CM
M93 is a non-billable header ICD-10-CM code for other osteochondropathies. 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.
- osteochondrosis of spine (M42.-)
Other codes that can never be billed with M93
These codes carry an Excludes1 note pointing at M93. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M93 alone.
Risk adjustment
M93 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 M93
5 child codes. Green means billable.
