ICD-10 Code C92.20 – Atypical chronic myeloid leukemia, BCR/ABL-negative, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.20 – Atypical chronic myeloid leukemia, BCR/ABL-negative, not having achieved remission
What it is
This code identifies atypical chronic myeloid leukemia that is BCR/ABL-negative and has not gone into remission. Use it when the record clearly documents this specific leukemia subtype and active disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include persistent leukemia with abnormal myeloid cells, splenomegaly, anemia, fatigue, or other signs of marrow involvement.
When to use this code
Use C92.20 when the provider documents atypical chronic myeloid leukemia, BCR/ABL-negative, and states the patient has not achieved remission. It is appropriate for active disease, ongoing evaluation, or follow-up when remission has not been documented. Check documentation if the record only says chronic myeloid leukemia without the atypical, BCR/ABL-negative, and remission details.
Do not use for
Do not use this code for chronic myeloid leukemia with BCR/ABL positivity, unspecified leukemia, or cases in remission. If the subtype or remission status is unclear, check documentation.
Coding tip
Confirm both the BCR/ABL-negative status and the “not having achieved remission” wording before assigning C92.20.
