What it is
C88.80 identifies a malignant immunoproliferative disorder that is still active and has not gone into remission. Use it when the record describes this category of disease without a more specific subtype.
Clinical signs
Clinical features vary; refer to documentation. These disorders may present with findings of abnormal lymphoid or plasma cell proliferation, but you should code only what the provider documents.
When to use this code
Use C88.80 when the diagnosis is documented as an other malignant immunoproliferative disease and the provider states it has not achieved remission. This code supports active disease status in the current encounter. Do not infer remission status from treatment alone; check documentation.
Do not use for
Do not use this code if the record names a more specific malignant immunoproliferative disorder or if remission is documented. Check documentation for the exact diagnosis and disease status.
Coding tip
Confirm both the exact disorder name and the phrase “not having achieved remission” before assigning C88.80.
