Myeloid sarcoma, in remission

This code signifies a rare extramedullary tumor composed of immature myeloid cells, also known as granulocytic sarcoma or chloroma, that is currently in a state of remission. It indicates that the patient has a history of myeloid sarcoma and is no longer exhibiting active disease.

Use this code when documentation confirms a past diagnosis of myeloid sarcoma and the patient is currently free of active disease, often following successful treatment. This code is appropriate for follow-up visits, surveillance, or when the patient's history of myeloid sarcoma in remission is relevant to their current care.

• Ensure documentation explicitly states "in remission" for myeloid sarcoma; otherwise, a code for active disease or history of myeloid sarcoma (without remission status) may be more appropriate.
• Do not confuse with codes for active myeloid sarcoma (C92.30) or personal history of myeloid sarcoma (Z85.6).
• Sequence this code as a secondary diagnosis if the patient is being seen for a complication or sequela related to the past myeloid sarcoma or its treatment.
