ICD-10 Code C94.00 – Acute erythroid leukemia, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C94.00 – Acute erythroid leukemia, not having achieved remission
What it is
C94.00 identifies acute erythroid leukemia that is still active and has not achieved remission. Use it when the record clearly states this specific leukemia subtype and remission status.
Clinical signs
Clinical features vary; refer to documentation. Typical records may describe an acute leukemia presentation with marrow involvement and findings consistent with erythroid-lineage disease.
When to use this code
Use this code when the provider documents acute erythroid leukemia and explicitly states the disease has not achieved remission. It may also be appropriate when the note clearly indicates persistent, active disease after prior therapy. If remission status is not stated, check documentation before coding.
Do not use for
Do not use this code for acute erythroid leukemia in remission or for cases where the leukemia type is different or unspecified. Check documentation if the diagnosis only says leukemia without the erythroid subtype.
Coding tip
Code the exact leukemia subtype and remission status together; if either element is missing, verify the provider’s documentation.
