C94.8

C94.8 — Other specified leukemias

Non-billable headerICD-10-CM

Acute basophilic leukemia

Excludes1 inherited from the categories above C94.8

These are not written on C94.8, but they bind it: a note on a category applies to every code beneath it. Billing C94.8 with anything listed here is a denial.

Written on C94 — Other leukemias of specified cell type

leukemic reticuloendotheliosis (C91.4-)
myelodysplastic syndromes (D46.-)
personal history of leukemia (Z85.6)
plasma cell leukemia (C90.1-)

Other codes that can never be billed with C94.8

These codes carry an Excludes1 note pointing at C94.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C94.8 alone.

Risk adjustment

C94.8 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.

Code history

C94.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead C94.8
