ICD-10 Code C93.30 – Juvenile myelomonocytic leukemia, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C93.30 – Juvenile myelomonocytic leukemia, not having achieved remission
What it is
C93.30 identifies juvenile myelomonocytic leukemia that is still active and has not reached remission. Use it when the record specifically states this diagnosis and indicates no remission.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings in juvenile myelomonocytic leukemia include persistent monocytosis, splenomegaly, and signs of marrow involvement, but you should code only what is documented.
When to use this code
Use this code when the provider documents juvenile myelomonocytic leukemia and clearly states it has not achieved remission. It is appropriate for active disease during initial workup, ongoing management, or follow-up when remission is not documented.
If the chart does not state remission status, check documentation before assigning this code. Do not assume remission or non-remission from treatment history alone.
Do not use for
Do not use this code for juvenile myelomonocytic leukemia in remission or when the record is silent about remission status. Check documentation if the condition is described only as suspected or ruled out.
Coding tip
Match the code to the exact remission wording in the provider note; if remission status is unclear, query the clinician.
