ICD-10 Code C92.32 – Myeloid sarcoma, in relapse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.32 – Myeloid sarcoma, in relapse
What it is
C92.32 identifies myeloid sarcoma that has returned after a prior remission or response. It is a localized tumor of immature myeloid cells occurring outside the bone marrow.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a mass or organ-specific lesion with pathology confirming myeloid origin, often alongside a history of acute myeloid leukemia or other myeloid neoplasm.
When to use this code
Use this code when the record clearly states myeloid sarcoma is in relapse or recurrent after prior treatment. It may also apply when the clinician documents recurrent extramedullary disease with confirmed myeloid pathology. Check that relapse status is explicit.
Do not use for
Do not use this code for initial presentation of myeloid sarcoma, unspecified disease status, or other leukemia without documented sarcoma. If the chart does not confirm relapse, check documentation.
Coding tip
Confirm both the myeloid sarcoma diagnosis and the relapse wording before assigning C92.32.
