Code Classification

Specific Coding for Chronic myelomonocytic leukemia

Non-specific codes like C93.1 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for chronic myelomonocytic leukemia:

  • BILLABLE CODE - Use C93.10 for Chronic myelomonocytic leukemia not having achieved remission
  • BILLABLE CODE - Use C93.11 for Chronic myelomonocytic leukemia, in remission
  • BILLABLE CODE - Use C93.12 for Chronic myelomonocytic leukemia, in relapse

Clinical Information

Information for Patients


Chronic Myeloid Leukemia

Also called: CML, Chronic granulocytic leukemia, Chronic myelogenous leukemia

Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In chronic myeloid leukemia (CML), there are too many granulocytes, a type of white blood cell.

Most people with CML have a gene mutation (change) called the Philadelphia chromosome.

Sometimes CML does not cause any symptoms. If you have symptoms, they may include:

Tests that examine the blood and bone marrow diagnose CML. Treatments include chemotherapy, stem cell transplants, infusion of donated white blood cells following stem cell transplants, surgery to remove the spleen, and biologic and targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses substances that attack cancer cells without harming normal cells.
