M83.3 — Adult osteomalacia due to malnutrition
M83.3 is a billable, specific ICD-10-CM code for adult osteomalacia due to malnutrition. It is valid for submission on a claim.
Excludes1 inherited from the categories above M83.3
These are not written on M83.3, but they bind it: a note on a category applies to every code beneath it. Billing M83.3 with anything listed here is a denial.
Other codes that can never be billed with M83.3
These codes carry an Excludes1 note pointing at M83.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M83.3 alone.
Risk adjustment
M83.3 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
M83.3 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.
