Code Description

ICD-10 C82.40 is a billable code used to indicate a diagnosis of follicular lymphoma grade iiib, 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. Grade IIIb indicates a more aggressive form of the disease, where more than 50% of the tumor consists of large cells, which can lead to a more rapid progression and poorer prognosis compared to lower grades. This subtype is often diagnosed in adults and can present with various symptoms, including lymphadenopathy, splenomegaly, and B-symptoms such as fever, night sweats, and weight loss. The unspecified site indicates that the lymphoma is not localized to a specific anatomical location, which can complicate treatment planning and staging. Treatment typically involves a combination of chemotherapy, immunotherapy, and sometimes radiation therapy, depending on the stage of the disease and the patient's overall health. Regular monitoring and follow-up are crucial due to the potential for transformation into a more aggressive lymphoma.

  • Variability in treatment protocols based on patient factors
  • Documentation of disease progression and response to treatment

Audit Risk Factors

  • Inadequate documentation of B-symptoms
  • Failure to specify the site of lymphoma involvement
  • Misclassification of lymphoma grade
  • Lack of follow-up documentation on treatment response
