C92.21
Atypical chronic myeloid leukemia, BCR/ABL-negative, in remission
Clinical Classification Guidelines
Medical Intelligence & Overview
Atypical chronic myeloid leukemia (aCML) is a rare form of blood cancer that affects the bone marrow and blood. Unlike typical chronic myeloid leukemia (CML), which usually involves the presence of the BCR/ABL gene fusion, aCML does not show this genetic marker. When treated effectively, the disease can enter a period of remission, meaning that signs and symptoms are reduced or disappear. Managing aCML requires ongoing medical care to monitor remission status and address any complications.
Causes & Symptoms
Clinical Causes: The exact cause of aCML is unknown. It is not typically inherited or contagious. Certain genetic mutations may play a role, but BCR/ABL gene presence is absent. Exposure to certain chemicals or radiation has been investigated, but no definitive link has been established.
Key Symptoms: Fatigue and weakness Unintentional weight loss Fever or night sweats Abdominal discomfort due to an enlarged spleen Easy bruising or bleeding Frequent infections Bone pain or tenderness
Diagnostic & Treatment
Diagnosis Path: Complete blood count (CBC) revealing increased white blood cells and other abnormalities Bone marrow biopsy to assess cellularity and blasts Genetic testing to rule out BCR/ABL gene fusion, confirming the atypical nature Additional molecular tests to identify other genetic mutations associated with the disease
Treatment Protocols: Chemotherapy to reduce abnormal blood cell production Targeted therapies, although options are limited compared to BCR/ABL-positive CML Supportive care with blood transfusions and antibiotics as needed Stem cell transplantation in selected cases, offering a potential cure

Documentation
How do I report C92.21?
