Code Description

ICD-10 C82.39 is a billable code used to indicate a diagnosis of follicular lymphoma grade iiia, extranodal and solid organ sites.

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 degree of malignancy, with more than 15% of the tumor composed of large cells. This specific code refers to cases where the lymphoma is present in extranodal sites, which can include organs such as the spleen, liver, or gastrointestinal tract. Patients may present with B-symptoms, which include fever, night sweats, and weight loss, indicating systemic involvement. Diagnosis typically involves imaging studies, biopsy, and immunophenotyping. Treatment protocols may include chemotherapy, immunotherapy, or targeted therapies, depending on the stage and patient health. The prognosis varies based on the extent of disease and response to treatment, necessitating careful staging and monitoring.
