Waldenstrom macroglobulinemia, in remission

This code signifies a malignant lymphoproliferative disorder characterized by the overproduction of IgM monoclonal paraprotein, currently in a state of remission. It represents a B-cell lymphoma that has responded to treatment, with no current evidence of active disease.

Apply this code when documentation explicitly states Waldenstrom macroglobulinemia is in remission following treatment. This typically indicates a period where the patient is being monitored for recurrence after achieving a complete or partial response. Supporting documentation would include physician notes confirming remission status, often based on laboratory values (e.g., stable or decreasing IgM levels) and clinical assessment.

• Do not use this code for active Waldenstrom macroglobulinemia; a different code exists for active disease.
• Ensure the medical record clearly specifies "remission" to justify using this code.
• Consider sequencing this code after any codes for current treatment encounters or complications related to the history of the disease.
