Sezary disease, in remission

This code signifies a current diagnosis of Sezary disease, a rare and aggressive form of cutaneous T-cell lymphoma, that is no longer exhibiting active signs or symptoms of the disease due to successful treatment. The patient's condition is stable and controlled, but the underlying malignancy remains.

Apply this code when documentation explicitly states "Sezary disease in remission" or similar phrasing indicating a complete or partial response to therapy with no current evidence of active disease. This typically follows a period of active treatment for Sezary disease.

• Do not use this code for active Sezary disease; refer to C84.10 for unspecified Sezary disease or other specific sub-codes if active.
• Ensure documentation clearly distinguishes between "in remission" and "history of" to avoid miscoding.
• Always sequence this code as the primary diagnosis if the patient is being seen for management of the remission state.
