Diagnosis Code 204.21
Information for Medical Professionals
The ICD-10 and ICD-9 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.
- C91.Z1 - Other lymphoid leukemia, in remission (approximate) 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.
Information for Patients
Also called: ALL, Acute lymphoblastic 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, however, 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 acute lymphocytic leukemia (ALL), also called acute lymphoblastic leukemia, there are too many of specific types of white blood cells called lymphocytes or lymphoblasts. ALL is the most common type of cancer in children.
Possible risk factors for ALL include being male, being white, previous chemotherapy treatment, exposure to radiation, and for adults, being older than 70.
Symptoms of ALL include:
- Weakness or feeling tired
- Easy bruising or bleeding
- Bleeding under the skin
- Shortness of breath
- Weight loss or loss of appetite
- Pain in the bones or stomach
- Pain or a feeling of fullness below the ribs
- Painless lumps in the neck, underarm, stomach, or groin
Tests that examine the blood and bone marrow diagnose ALL. Treatments include chemotherapy, radiation therapy, stem cell transplants, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells. Once the leukemia is in remission, you need additional treatment to make sure that it does not come back.
