Angioimmunoblastic T-cell lymphoma, in remission

This code signifies a diagnosis of angioimmunoblastic T-cell lymphoma (AITL) that is currently in remission. AITL is a rare, aggressive peripheral T-cell lymphoma characterized by systemic symptoms, lymphadenopathy, and often polyclonal hypergammaglobulinemia. "In remission" indicates that the signs and symptoms of the disease have significantly decreased or disappeared due following treatment.

This code is appropriate when a patient has a documented history of angioimmunoblastic T-cell lymphoma and clinical assessment confirms the disease is currently in remission. Documentation should clearly state "remission" or "in remission" for AITL, typically supported by imaging, laboratory results, and physician notes.

• Do not use this code for active disease; a different code for active AITL would be appropriate.
• Ensure documentation explicitly states "remission" for angioimmunoblastic T-cell lymphoma, not just "stable" or "responding to treatment" without further clarification of remission status.
• Consider sequencing this code after any codes for current treatment or complications related to the history of AITL, if applicable.
