C95 — Leukemia of unspecified cell type
Is C95 billable?
No — C95 is a non-billable header code. C95 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 9 billable codes beneath C95.

Excludes1 — never code together
The conditions below can never be reported together with C95 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- personal history of leukemia (Z85.6)
Excludes2 — not included here — inherited from C81-C96
The conditions below are not part of C95, but a patient may have both at the same time. When documentation supports it, C95 and the excluded code may both be reported.
