Extranodal NK/T-cell lymphoma, nasal type, in remission

This code signifies a patient with a history of extranodal NK/T-cell lymphoma, nasal type, who is currently experiencing no evidence of active disease. This aggressive non-Hodgkin lymphoma primarily affects the nasal cavity and surrounding structures. "In remission" indicates that treatment has been successful in eradicating detectable cancer cells.

Use this code when documentation clearly states that a patient previously diagnosed with extranodal NK/T-cell lymphoma, nasal type, is now in remission. This typically applies to follow-up visits, surveillance, or when the patient is receiving maintenance therapy after achieving complete remission. Supporting documentation should include a definitive diagnosis of the specific lymphoma type and a physician's statement confirming the remission status.

• Always ensure the documentation specifies "nasal type" to differentiate from other extranodal NK/T-cell lymphomas.
• Do not use this code if the patient has active disease or is in relapse; a code for active lymphoma would be more appropriate.
• Consider sequencing this code after any Z codes for follow-up care or surveillance, if applicable.
