Code Description

ICD-10 C82.11 is a billable code used to indicate a diagnosis of follicular lymphoma grade ii, lymph nodes of head, face, and neck.

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. This subtype is typically indolent but can transform into a more aggressive form. It primarily affects the lymph nodes in the head, face, and neck regions, presenting with painless lymphadenopathy. Patients may experience B-symptoms, which include fever, night sweats, and unexplained weight loss. Diagnosis is confirmed through histological examination of lymph node biopsies, which reveal a mixture of small and large cells. Staging is crucial for treatment planning and involves imaging studies such as CT scans or PET scans to assess the extent of disease. Treatment options may include watchful waiting for asymptomatic patients, chemotherapy, immunotherapy, or radiation therapy, depending on the stage and symptoms. The prognosis varies based on the individual’s overall health, age, and response to treatment.
