Code Description

ICD-10 C82.03 is a billable code used to indicate a diagnosis of follicular lymphoma grade i, intra-abdominal lymph nodes.

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, which typically has a more indolent course compared to higher-grade lymphomas. Intra-abdominal lymph nodes are involved in this specific diagnosis, indicating that the lymphoma has localized to the abdominal region. Patients may present with symptoms such as abdominal pain, swelling, or discomfort due to lymphadenopathy. Follicular lymphoma is often diagnosed through imaging studies and confirmed via biopsy. Staging is crucial, as it helps determine the extent of the disease and guides treatment decisions. The Ann Arbor staging system is commonly used, with stages I-IV indicating the spread of the disease. B-symptoms, including fever, night sweats, and weight loss, may or may not be present and can influence prognosis and treatment strategies. Treatment options may include watchful waiting, chemotherapy, immunotherapy, or radiation therapy, depending on the stage and symptoms.
