Code Description

ICD-10 C82.33 is a billable code used to indicate a diagnosis of follicular lymphoma grade iiia, 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 IIIa indicates a higher grade of malignancy, where there is a predominance of large cells, and it is classified as a more aggressive form of lymphoma. Intra-abdominal lymph nodes are involved, which may include lymph nodes in the mesentery, retroperitoneum, or other abdominal regions. Patients may present with B-symptoms such as fever, night sweats, and weight loss, which are indicative of systemic disease. Diagnosis typically involves imaging studies such as CT scans and biopsy of affected lymph nodes. Treatment protocols may include chemotherapy regimens, immunotherapy, or targeted therapies, depending on the stage and overall health of the patient. The prognosis varies based on the disease stage, patient age, and response to treatment, with ongoing monitoring required for disease progression or recurrence.
