Mature T/NK-cell lymphomas, unspecified, in remission

This code signifies a past diagnosis of a mature T-cell or NK-cell lymphoma, which is a type of non-Hodgkin lymphoma originating from mature T-lymphocytes or natural killer cells, and is currently in a state of remission. "Unspecified" indicates that the specific subtype of mature T/NK-cell lymphoma is not documented.

Utilize this code when a patient has a documented history of a mature T/NK-cell lymphoma, and clinical records confirm that the disease is currently in remission. This applies to situations where the specific subtype of T/NK-cell lymphoma is not identified in the documentation. Supporting documentation would include physician notes indicating "history of T-cell lymphoma, in remission" or "NK-cell lymphoma, currently in remission, type unspecified."

• Always sequence this code after the appropriate personal history code (Z85.79) if the patient is no longer receiving active treatment.
• Do not use this code if the patient is still undergoing active treatment for the lymphoma, even if the disease is responding.
• Ensure documentation clearly states "in remission" and that the specific subtype of mature T/NK-cell lymphoma is not specified.
