Angioimmunoblastic T-cell lymphoma not achieve remission

This code signifies a specific type of mature T-cell lymphoma, angioimmunoblastic T-cell lymphoma (AITL), that is currently active and has not yet responded to treatment to the point of remission. AITL is an aggressive non-Hodgkin lymphoma characterized by systemic symptoms, lymphadenopathy, and often skin rashes or autoimmune phenomena.

Use this code when documentation clearly indicates a diagnosis of angioimmunoblastic T-cell lymphoma and explicitly states that the disease has not achieved remission. This applies to initial diagnoses, ongoing treatment phases, or follow-up encounters where remission has not been attained. Supporting documentation includes pathology reports confirming AITL and physician notes detailing the current disease status.

• Do not use this code if the patient is in remission or has a history of AITL but is currently disease-free.
• Ensure the documentation specifies "angioimmunoblastic" as opposed to other T-cell lymphomas.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by codes for any associated symptoms or complications.
