D64.9 — Anemia, unspecified
D64.9 is a billable, specific ICD-10-CM code for anemia, unspecified. It is valid for submission on a claim.
Excludes1 inherited from the categories above D64.9
These are not written on D64.9, but they bind it: a note on a category applies to every code beneath it. Billing D64.9 with anything listed here is a denial.
Other codes that can never be billed with D64.9
These codes carry an Excludes1 note pointing at D64.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D64.9 alone.
- D53.9Nutritional anemia, unspecified
Risk adjustment
D64.9 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
D64.9 is named in 21 Medicare coverage policies — 20 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
