Code Description

ICD-10 C82.31 is a billable code used to indicate a diagnosis of follicular lymphoma grade iiia, lymph nodes of head, face, and neck.

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 level of malignancy, with a greater number of large cells present in the tumor. This specific code pertains to cases where the lymphoma is localized to the lymph nodes of the head, face, and neck region. Patients may present with painless lymphadenopathy, and the disease can be indolent or aggressive. Staging is crucial, often utilizing the Ann Arbor system, which assesses the extent of disease spread. B-symptoms, including fever, night sweats, and weight loss, may be present and are indicative of systemic involvement. Treatment protocols typically involve chemotherapy, immunotherapy, or radiation therapy, depending on the stage and patient health. Accurate coding is essential for appropriate treatment planning and reimbursement.

Frequently Asked Questions

What is the significance of the grade in follicular lymphoma?

The grade indicates the aggressiveness of the lymphoma, with higher grades (like IIIa) suggesting a more aggressive disease that may require more intensive treatment.
