2026 ICD-10-CM Diagnosis Code C94.20 – Acute megakaryoblastic leukemia not having achieved remission
What it is
This code identifies acute megakaryoblastic leukemia that is still active and has not gone into remission. Use it when the record specifically states the disease is not in remission.
Clinical signs
Clinical features vary; refer to documentation. Typical findings in acute leukemia may include anemia, bleeding, infection, and evidence of abnormal megakaryoblasts on marrow or blood evaluation.
When to use this code
Use C94.20 when the provider documents acute megakaryoblastic leukemia and states it has not achieved remission. It also fits follow-up notes that still describe active disease after treatment. If remission status is unclear, check documentation before assigning this code.
Do not use for
Do not use this code if the leukemia is documented as in remission or if the record does not specify remission status. Check documentation for other leukemia subtypes.
Coding tip
Always confirm the exact leukemia type and remission status in the provider note before coding.
