Multiple Myeloma

Multiple myeloma is a cancer that begins in plasma cells, a type of white blood cell. These cells are part of your immune system, which helps protect the body from germs and other harmful substances. In time, myeloma cells collect in the bone marrow and in the solid parts of bones.

No one knows the exact causes of multiple myeloma, but it is more common in older people and African Americans. It can run in families. Common symptoms may include:

  • Bone pain, often in the back or ribs
  • Fractures (broken bones)
  • Weakness or fatigue
  • Weight loss
  • Frequent infections and fevers
  • Feeling very thirsty
  • Frequent urination

Doctors diagnose multiple myeloma using lab tests, imaging tests, and a bone marrow biopsy. Your treatment depends on how advanced the disease is and whether you have symptoms. If you have no symptoms, you may not need treatment right away. If you have symptoms, you may have chemotherapy, stem cell transplantation, radiation, or targeted therapy. Targeted therapy uses drugs or other substances that attack specific cancer cells with less harm to 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.
