Chronic myelomonocytic leukemia, in remission

This code signifies a chronic myelomonocytic leukemia (CMML) that is currently in remission. CMML is a clonal hematopoietic stem cell disorder characterized by persistent peripheral blood monocytosis and features of both myelodysplastic syndromes and myeloproliferative neoplasms. "In remission" indicates that the signs and symptoms of the disease have significantly decreased or disappeared, often due to successful treatment.

Use this code when a patient has a documented history of chronic myelomonocytic leukemia and current clinical and laboratory findings confirm a state of remission. This typically applies to follow-up encounters for patients who have undergone treatment (e.g., chemotherapy, stem cell transplant) and are no longer exhibiting active disease progression. Documentation should clearly state "CMML in remission" or similar.

• Always confirm the specific type of leukemia (myelomonocytic) and the remission status from the physician's documentation.
• Do not confuse with active CMML (C93.10) or CMML in relapse.
• Sequence this code as a primary diagnosis when the encounter is for management of the remission or related follow-up care.
