Adult T-cell lymph/leuk (HTLV-1-assoc) not achieve remission

This code signifies a diagnosis of Adult T-cell lymphoma/leukemia (ATLL) that is specifically linked to Human T-lymphotropic virus type 1 (HTLV-1) infection. It indicates that the disease is currently active and has not responded to treatment to the point of remission. ATLL is an aggressive malignancy of mature T-lymphocytes.

Use this code for patients with a confirmed diagnosis of HTLV-1-associated ATLL who are currently undergoing treatment or have completed treatment but have not achieved remission. Documentation should clearly state the diagnosis of ATLL, its association with HTLV-1, and the current disease status as "not in remission" or "active disease."

• Always confirm the HTLV-1 association; if not specified, a different ATLL code may be appropriate.
• Distinguish carefully between "not having achieved remission" and "in remission" or "in relapse" as these have distinct codes.
• Ensure documentation supports the active disease state, such as ongoing treatment, persistent symptoms, or laboratory findings indicating active malignancy.
