Multiple myeloma in remission

This code signifies a patient with a history of multiple myeloma where the disease is currently in a state of remission. Remission indicates a significant reduction or disappearance of signs and symptoms of the cancer, though the patient still requires ongoing monitoring for potential recurrence.

Apply this code when documentation clearly states that a patient with a prior diagnosis of multiple myeloma is currently in remission. This is typically supported by laboratory results (e.g., normal serum protein electrophoresis, absence of M-protein) and clinical assessment indicating no active disease.

• Always sequence this code after the appropriate Z code indicating personal history of malignant neoplasm (Z85.79).
• Do not use this code if the patient has active multiple myeloma; instead, use the appropriate code from the C90.0- series for active disease.
• Ensure the medical record explicitly states "in remission" for multiple myeloma to support the use of this code.
