Code Description

ICD-10 C82.04 is a billable code used to indicate a diagnosis of follicular lymphoma grade i, lymph nodes of axilla and upper limb.

Key Diagnostic Point:

Follicular lymphoma is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. Grade I indicates a low-grade lymphoma with a relatively indolent course. This specific code pertains to cases where the lymphoma is localized to the lymph nodes of the axilla and upper limb. Patients may present with painless lymphadenopathy, and the disease can be asymptomatic for long periods. Staging is crucial, typically using the Ann Arbor system, which assesses the extent of disease based on lymph node involvement and the presence of B-symptoms such as fever, night sweats, and weight loss. Treatment often involves watchful waiting for asymptomatic patients, while symptomatic cases may require chemotherapy, immunotherapy, or radiation therapy. The prognosis for grade I follicular lymphoma is generally favorable, but careful monitoring is essential due to the potential for transformation to a more aggressive form of lymphoma.
