Follicular lymphoma grade I, in remission

This code signifies a diagnosis of follicular lymphoma, specifically grade I, which is currently in a state of remission. Follicular lymphoma is a slow-growing (indolent) non-Hodgkin lymphoma originating from B-lymphocytes. Remission indicates that the signs and symptoms of the cancer have disappeared or significantly reduced due to treatment.

Use this code when documentation clearly states that a patient has a history of grade I follicular lymphoma and is currently in remission. This typically applies to follow-up encounters where the patient is being monitored after successful treatment. Supporting documentation would include pathology reports confirming grade I follicular lymphoma and physician notes indicating the current remission status.

• Always confirm the specific grade of follicular lymphoma (I, II, III, or unspecified) as different grades have distinct codes.
• Ensure the documentation explicitly states "in remission" to use this code; if the disease is active or recurrent, a different code is required.
• Sequence this code as a secondary diagnosis if the primary reason for the encounter is surveillance or management of long-term effects of treatment.
