ICD-10 Code C92.40 – Acute promyelocytic leukemia, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.40 – Acute promyelocytic leukemia, not having achieved remission
What it is
This code identifies acute promyelocytic leukemia that is still active and has not gone into remission. Use it when the record clearly states APL without remission or equivalent wording.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record may describe acute leukemia findings, abnormal promyelocytes, and related marrow or blood evidence supporting APL.
When to use this code
Use C92.40 when the provider documents acute promyelocytic leukemia and specifically states it has not achieved remission. It also fits when the note indicates persistent active disease after prior therapy. If remission status is unclear, check documentation before coding.
Do not use for
Do not use this code for APL in remission or for cases where the documentation only says leukemia without specifying promyelocytic type. Check documentation if the remission status is missing.
Coding tip
Code the remission status exactly as documented, because APL has separate ICD-10-CM codes for remission and non-remission.
