Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Antineoplastic chemotherapy induced anemia
Excludes1 inherited from the categories above D64.81
These are not written on D64.81, but they bind it: a note on a category applies to every code beneath it. Billing D64.81 with anything listed here is a denial.
Risk adjustment
D64.81 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
D64.81 is named in 11 Medicare coverage policies — 11 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
