Follicular lymphoma grade IIIa, in remission

This code signifies a specific type of non-Hodgkin lymphoma, follicular lymphoma, which is characterized by a grade IIIa cellular morphology. The "in remission" status indicates that the signs and symptoms of the cancer have significantly decreased or disappeared, but the patient still requires ongoing monitoring.

Use this code when documentation confirms a diagnosis of follicular lymphoma, specifically grade IIIa, and the patient is currently in a state of remission. This typically applies to patients who have completed initial treatment and are now being monitored for recurrence. Supporting documentation would include pathology reports confirming grade IIIa and physician notes indicating remission status.

• Ensure the documentation clearly specifies "grade IIIa" as other grades of follicular lymphoma have distinct codes.
• Verify the "in remission" status; if the lymphoma is active, a different code from the C82.3- series would be appropriate.
• Always sequence this code as a secondary diagnosis if the patient is receiving treatment for a complication or sequela related to the past lymphoma.
