M84
M84 — Disorder of continuity of bone
Non-billable headerICD-10-CM
M84 is a non-billable header ICD-10-CM code for disorder of continuity of bone. 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.
- traumatic fracture of bone-see fracture, by site
Other codes that can never be billed with M84
These codes carry an Excludes1 note pointing at M84. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M84 alone.
Risk adjustment
M84 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 M84
