Other malignant immunoproliferative diseases, in remission

This code signifies a malignant condition affecting the immune system's B-cells or T-cells, which is currently in a state of remission. These are rare cancers characterized by the uncontrolled proliferation of lymphocytes or plasma cells, but the patient is no longer exhibiting active disease symptoms or signs.

This code is used when a patient has a history of a malignant immunoproliferative disease (e.g., lymphoplasmacytic lymphoma, heavy chain disease) that is currently in remission. Documentation should clearly state the specific type of immunoproliferative disease and confirm its remission status, often following successful treatment.

• Always sequence this code after any codes for current active treatment or complications related to the history of the disease.
• Do not use this code for conditions that are cured; remission implies the potential for recurrence.
• Ensure the specific type of "other malignant immunoproliferative disease" is documented to support this more general code.
