Code Description

ICD-10 C82.15 is a billable code used to indicate a diagnosis of follicular lymphoma grade ii, lymph nodes of inguinal region and lower limb.

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. The involvement of lymph nodes in the inguinal region and lower limb indicates a specific anatomical localization of the disease. Patients may present with painless lymphadenopathy, and the disease can be associated with B-symptoms such as fever, night sweats, and weight loss. Staging of follicular lymphoma is crucial for determining prognosis and treatment options, with the Ann Arbor staging system commonly used. Treatment protocols may include watchful waiting for asymptomatic patients, chemotherapy, immunotherapy, or radiation therapy, depending on the stage and symptoms. The prognosis varies, with factors such as age, performance status, and the presence of B-symptoms influencing outcomes.
