M88.1 — Osteitis deformans of vertebrae
M88.1 is a billable, specific ICD-10-CM code for osteitis deformans of vertebrae. It is valid for submission on a claim.
Excludes1 inherited from the categories above M88.1
These are not written on M88.1, but they bind it: a note on a category applies to every code beneath it. Billing M88.1 with anything listed here is a denial.
Other codes that can never be billed with M88.1
These codes carry an Excludes1 note pointing at M88.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M88.1 alone.
Risk adjustment
M88.1 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.
Medicare coverage
M88.1 is named in 15 Medicare coverage policies — 8 listing it as supporting medical necessity, and 7 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How M88.1 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to M88.1.
