M83.1 — Senile osteomalacia
M83.1 is a billable, specific ICD-10-CM code for senile osteomalacia. It is valid for submission on a claim.
Excludes1 inherited from the categories above M83.1
These are not written on M83.1, but they bind it: a note on a category applies to every code beneath it. Billing M83.1 with anything listed here is a denial.
Other codes that can never be billed with M83.1
These codes carry an Excludes1 note pointing at M83.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M83.1 alone.
Risk adjustment
M83.1 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
M83.1 is named in 18 Medicare coverage policies — 11 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 M83.1 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 M83.1.
