Code Description

ICD-10 C82.46 is a billable code used to indicate a diagnosis of follicular lymphoma grade iiib, intrapelvic 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 IIIb indicates a more aggressive form of the disease, where there is a predominance of large cells, often leading to a more rapid progression. In this case, the lymphoma is localized to the intrapelvic lymph nodes, which can include nodes in the iliac, inguinal, and pelvic regions. Patients may present with B-symptoms such as fever, night sweats, and weight loss, which are indicative of systemic involvement. Diagnosis typically involves imaging studies such as CT scans and biopsy of affected lymph nodes. Treatment protocols may include chemotherapy, immunotherapy, or radiation therapy, depending on the stage and symptoms. The prognosis can vary significantly based on the grade and extent of the disease, with grade IIIb generally associated with a poorer prognosis compared to lower grades.
