Code Description

ICD-10 C82.13 is a billable code used to indicate a diagnosis of follicular lymphoma grade ii, intra-abdominal lymph nodes.

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 intra-abdominal lymph nodes indicates that the lymphoma has spread beyond its original site, which can complicate treatment and prognosis. Patients may present with B-symptoms such as fever, night sweats, and weight loss, which are indicative of systemic disease. Staging is crucial in determining the extent of the disease, with the Ann Arbor staging system commonly used. Treatment protocols often include watchful waiting for asymptomatic patients, while symptomatic cases may require chemotherapy, immunotherapy, or targeted therapies. The prognosis for grade II follicular lymphoma can vary based on factors such as age, overall health, and response to treatment.
