C94Other leukemias of specified cell type

Not billable

Is C94 billable?

No — C94 is a non-billable header code. C94 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 16 billable codes beneath C94.

Excludes1 — never code together

The conditions below can never be reported together with C94 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

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

Excludes2 — not included here — inherited from C81-C96

The conditions below are not part of C94, but a patient may have both at the same time. When documentation supports it, C94 and the excluded code may both be reported.

  • Kaposi's sarcoma of lymph nodes (C46.3)
  • secondary and unspecified neoplasm of lymph nodes (C77.-)
  • secondary neoplasm of bone marrow (C79.52)
  • secondary neoplasm of spleen (C78.89)
