ICD-9 Code 205.12

Chronic myeloid leukemia, in relapse

Not Valid for Submission

205.12 is a legacy non-billable code used to specify a medical diagnosis of chronic myeloid leukemia, in relapse. This code was replaced on September 30, 2015 by its ICD-10 equivalent.

ICD-9: 205.12
Short Description:Chr myel leuk in relapse
Long Description:Chronic myeloid leukemia, in relapse

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:

  • Fatigue
  • Weight loss
  • Night sweats
  • Fever
  • Pain or a feeling of fullness below the ribs on the left side

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.

General Equivalence Map Definitions
The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
