Code Description

ICD-10 C82.94 is a billable code used to indicate a diagnosis of follicular lymphoma, unspecified, 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. It is typically indolent but can transform into a more aggressive form. The unspecified designation indicates that the specific subtype or characteristics of the lymphoma have not been detailed. This code specifically pertains to cases where the lymphoma is localized to the lymph nodes of the axilla and upper limb. Patients may present with painless lymphadenopathy in these regions. Follicular lymphoma is often diagnosed through biopsy and histological examination, which reveals follicular patterns of neoplastic cells. Staging is crucial, as it influences treatment decisions and prognosis. The Ann Arbor staging system is commonly used, with stages I-IV indicating the extent of disease spread. B-symptoms, including fever, night sweats, and weight loss, may be present and are significant for staging and treatment planning. Treatment options vary from watchful waiting in asymptomatic cases to chemotherapy, immunotherapy, and targeted therapies in symptomatic or advanced cases.
