2024 ICD-10-CM Diagnosis Code C90.30

Approximate Synonyms

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

• Multiple solitary plasmacytomas
• Non-Hodgkin's lymphoma of bone
• Plasma cell myeloma/plasmacytoma
• Plasmacytoma
• Primary bone lymphoma
• Solitary osseous myeloma

Clinical Information

• Interleukin-6

  a cytokine that stimulates the growth and differentiation of b-lymphocytes and is also a growth factor for hybridomas and plasmacytomas. it is produced by many different cells including t-lymphocytes; monocytes; and fibroblasts.

• Plasmacytoma

  any discrete, presumably solitary, mass of neoplastic plasma cells either in bone marrow or various extramedullary sites.

C90.30 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
820	LYMPHOMA AND LEUKEMIA WITH MAJOR O.R. PROCEDURES WITH MCC	17	6.0467
821	LYMPHOMA AND LEUKEMIA WITH MAJOR O.R. PROCEDURES WITH CC	17	2.2321
822	LYMPHOMA AND LEUKEMIA WITH MAJOR O.R. PROCEDURES WITHOUT CC/MCC	17	1.2388

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert C90.30 to ICD-9-CM

  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

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.
