C95 — Leukemia of unspecified cell type

Non-billable headerICD-10-CM

C95 is a non-billable header ICD-10-CM code for leukemia of unspecified cell type. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Other codes that can never be billed with C95

These codes carry an Excludes1 note pointing at C95. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C95 alone.

Risk adjustment

C95 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 to one of these instead C95

3 child codes. Green means billable.
