What This Code Means

A solid tumor made of myeloid cancer cells that is currently in remission.

Coding Tips

•Document the anatomical site of the myeloid sarcoma when possible
•Verify remission status is explicitly stated in the clinical documentation

Clinical Significance

Myeloid sarcoma in remission indicates resolution of the extramedullary myeloid tumor after treatment. Remission requires both local tumor resolution and absence of systemic AML in the bone marrow. Patients with myeloid sarcoma in remission require surveillance for late relapse, which may present as recurrent extramedullary disease, new bone marrow-based AML, or both.

Documentation Requirements

✓Provider must document resolution of the extramedullary mass by imaging and normalization of the bone marrow biopsy.
✓The treatment that achieved remission and date of response should be recorded.
✓Ongoing surveillance plan including imaging of prior tumor sites and bone marrow monitoring must be documented.
✓Post-remission therapy (consolidation chemotherapy or transplant consideration) should be noted.

Commonly Confused Codes

C92.30 (myeloid sarcoma not in remission) is for active disease.C92.32 (myeloid sarcoma in relapse) is for recurrent disease.C92.01 (AML in remission) may be used if there was concurrent bone marrow disease.Z85.6 (personal history of leukemia) should not be used while active surveillance continues.
