Code Description

ICD-10 C82.16 is a billable code used to indicate a diagnosis of follicular lymphoma grade ii, 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 II indicates an intermediate level of aggressiveness, with a higher number of centroblasts compared to grade I. In this case, the lymphoma is specifically located in the intrapelvic lymph nodes, which can include nodes in the iliac, inguinal, or pelvic regions. Patients may present with B-symptoms such as fever, night sweats, and unexplained weight loss, which can indicate a more advanced disease state. Diagnosis typically involves imaging studies such as CT scans or PET scans, along with biopsy of affected lymph nodes. Treatment protocols often include watchful waiting for asymptomatic patients, followed by chemotherapy, immunotherapy, or radiation therapy for symptomatic cases. The prognosis varies based on the stage at diagnosis and response to treatment, with a focus on managing symptoms and improving quality of life.
