Code Description

ICD-10 C82.90 is a billable code used to indicate a diagnosis of follicular lymphoma, unspecified, unspecified site.

Key Diagnostic Point:

Follicular lymphoma is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. It is typically indolent, meaning it often progresses slowly, and can present at various stages. The unspecified site indicates that the lymphoma has not been localized to a specific anatomical region, which can complicate treatment and prognosis. Patients may present with B-symptoms, which include fever, night sweats, and weight loss, indicating systemic involvement. Staging is crucial in determining the extent of the disease, with the Ann Arbor staging system commonly used. Treatment protocols may vary based on the stage and symptoms, ranging from watchful waiting in asymptomatic cases to chemotherapy, immunotherapy, or radiation therapy in symptomatic or advanced cases. The prognosis for follicular lymphoma can vary widely, with some patients experiencing long periods of remission, while others may have more aggressive disease requiring intensive treatment.
