C94.8 — Other specified leukemias
Is C94.8 billable?
No — C94.8 is a non-billable header code. C94.8 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 3 billable codes beneath C94.8.

Excludes1 — never code together — inherited from C94
The conditions below can never be reported together with C94.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from C81-C96
The conditions below are not part of C94.8, but a patient may have both at the same time. When documentation supports it, C94.8 and the excluded code may both be reported.
