D70.9 — Neutropenia, unspecified
D70.9 is a billable, specific ICD-10-CM code for neutropenia, unspecified. It is valid for submission on a claim.
Risk adjustment
D70.9 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
D70.9 is named in 22 Medicare coverage policies — 22 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
