ICD-10 Code C92.30 – Myeloid sarcoma, not having achieved remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C92.30 – Myeloid sarcoma, not having achieved remission
What it is
C92.30 identifies myeloid sarcoma that is still active and has not gone into remission. It is a tumor made of myeloid cells occurring outside the bone marrow, documented as not in remission.
Clinical signs
Findings depend on the site involved and may include a mass, pain, swelling, or organ-related symptoms. Clinical features vary; refer to documentation for confirmation that the lesion is myeloid sarcoma and not in remission.
When to use this code
Use this code when the record clearly states myeloid sarcoma and indicates it has not achieved remission. It is appropriate for ongoing disease during treatment, persistent disease after therapy, or relapse when the provider documents non-remission. Check documentation if remission status is unclear.
Do not use for
Do not use this code for a history of myeloid sarcoma in remission or when the diagnosis is only suspected. Do not assign it if the chart documents another myeloid neoplasm instead.
Coding tip
Always verify the exact wording for remission status, because the code depends on provider documentation.
