Non-follicular (diffuse) lymphoma, unspecified, in remission

This code signifies a diagnosis of non-follicular lymphoma, which is a broad category encompassing various types of diffuse lymphomas, where the specific subtype is not documented. The "in remission" status indicates that the signs and symptoms of the lymphoma have significantly decreased or disappeared, but the patient still requires ongoing monitoring.

Apply this code when documentation specifies a diffuse lymphoma, without further histological detail, and explicitly states the disease is currently in remission. This is appropriate for patients who have completed treatment and are now in a surveillance phase, with no active disease manifestations.

• Ensure documentation clearly states "diffuse" or "non-follicular" and "unspecified" if no further subtype is identified.
• Do not use this code for active disease or when a specific subtype of diffuse lymphoma (e.g., diffuse large B-cell lymphoma) is documented.
• Always sequence this code after any codes for the history of the lymphoma or any current complications related to its past treatment.
