Waldenstrom macroglobulinemia not having achieved remission

This code identifies Waldenstrom macroglobulinemia (WM), a rare, slow-growing B-cell lymphoma characterized by the overproduction of IgM antibodies, when the disease is still active and has not achieved a state of remission. It indicates ongoing disease activity requiring continued management or monitoring.

Apply this code when a patient with a confirmed diagnosis of Waldenstrom macroglobulinemia is currently undergoing treatment or is being monitored for active disease, and their condition has not yet reached a state of complete or partial remission. Documentation should clearly state active WM, without mention of remission.

• Do not use this code if the patient has achieved complete or partial remission; instead, refer to codes for WM in remission.
• Ensure documentation explicitly states "not in remission" or implies active disease requiring ongoing management.
• Sequence this code as the primary diagnosis when WM is the reason for the encounter, or as a secondary diagnosis when it impacts the primary condition.
