Blastic NK-cell lymphoma, in remission

This code signifies a diagnosis of blastic natural killer (NK)-cell lymphoma that is currently in a state of remission. Blastic NK-cell lymphoma is a rare and aggressive hematologic malignancy characterized by the proliferation of immature NK cells. "In remission" indicates that the signs and symptoms of the disease have significantly decreased or disappeared following treatment.

Use this code when documentation explicitly states that a patient has a history of blastic NK-cell lymphoma and is currently in remission. This typically applies to follow-up encounters, surveillance, or when the patient is receiving maintenance therapy after achieving remission. Ensure the physician's notes clearly specify "in remission" or a similar term.

• Do not use this code if the patient is still actively undergoing treatment for active disease; instead, use the code for active blastic NK-cell lymphoma.
• Always sequence this code after any codes for current treatment or complications related to the lymphoma or its treatment.
• Verify that the documentation specifies "blastic NK-cell lymphoma" and not another type of NK-cell lymphoma, as there are distinct codes for other forms.
