C90.01 - Multiple myeloma in remission

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Asymptomatic multiple myeloma
• Immunoproliferative neoplasm in remission
• Indolent multiple myeloma
• Malignant lymphoma in remission
• Multiple myeloma in remission
• Non-Hodgkin's lymphoma in remission
• Smoldering myeloma

Clinical Information

• Multiple Myeloma-. a malignancy of mature plasma cells engaging in monoclonal immunoglobulin production. it is characterized by hyperglobulinemia, excess bence-jones proteins (free monoclonal immunoglobulin light chains) in the urine, skeletal destruction, bone pain, and fractures. other features include anemia; hypercalcemia; and renal insufficiency.
• Smoldering Multiple Myeloma-. an asymptomatic and slow-growing plasma cell dyscrasia characterized by presence of myeloma proteins and clonal bone marrow plasma cells without end-organ damage (e.g., renal impairment). it is distinguished from monoclonal gammopathy of undetermined significance by a much higher risk of progression to symptomatic multiple myeloma.

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

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.

Multiple myeloma

Multiple myeloma is a cancer that develops in the bone marrow, the spongy tissue found in the center of most bones. The bone marrow produces red blood cells, which carry oxygen throughout the body; white blood cells, which form the body's defenses (immune system); and platelets, which are necessary for blood clotting.

Multiple myeloma is characterized by abnormalities in plasma cells, a type of white blood cell. These abnormal cells multiply out of control, increasing from about one percent of cells in the bone marrow to the majority of bone marrow cells. The abnormal cells form tumors within the bone, causing bone pain and an increased risk of fractures. If the tumors interfere with nerves near the bones, numbness or weakness in the arms or legs can occur. Affected individuals may also experience a loss of bone tissue, particularly in the skull, spine, ribs, and pelvis. The deterioration of bone can result in an excess of calcium in the blood (hypercalcemia), which can lead to nausea and loss of appetite, excessive thirst, fatigue, muscle weakness, and confusion.

The abnormal plasma cells in multiple myeloma produce proteins that impair the development of normal blood cells. As a result, affected individuals may have a reduced number of red blood cells (anemia), which can cause fatigue, weakness, and unusually pale skin (pallor); a low number of white blood cells (leukopenia), which can result in a weakened immune system and frequent infections such as pneumonia; and a reduced number of platelets (thrombocytopenia), which can lead to abnormal bleeding and bruising. Kidney problems can also occur in this disorder, caused by hypercalcemia or by toxic proteins produced by the abnormal plasma cells.

People with multiple myeloma typically develop the disorder around age 65. Over time, affected individuals can develop life-threatening complications, but the rate at which this happens varies widely. Some affected individuals are diagnosed incidentally when tests are done for other purposes and do not experience symptoms for years.
