Code Description

ICD-10 C82.1 is a billable code used to indicate a diagnosis of follicular lymphoma grade ii.

Key Diagnostic Point:

Follicular lymphoma grade II is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. It is classified as a low-grade lymphoma but has features that can lead to a more aggressive clinical course compared to grade I. Patients typically present with painless lymphadenopathy, and the disease can involve multiple lymph node regions as well as extranodal sites. The diagnosis is confirmed through histopathological examination, which reveals a mixture of small and large cells, with a predominance of large cells. Staging is crucial and follows the Ann Arbor classification, which assesses the extent of lymph node involvement and any extranodal disease. B-symptoms, including fever, night sweats, and weight loss, may be present and are indicative of more advanced disease. Treatment protocols often include watchful waiting for asymptomatic patients, while symptomatic individuals may require chemotherapy, immunotherapy, or radiation therapy. The prognosis varies based on the stage at diagnosis and the patient's overall health.
