Code Description

ICD-10 C82.20 is a billable code used to indicate a diagnosis of follicular lymphoma grade iii, 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. Grade III indicates a more aggressive form of the disease, with a higher proliferation index and a greater likelihood of transformation to a more aggressive lymphoma. This code is used when the specific site of the lymphoma is not documented, which can complicate treatment planning and prognosis. Patients may present with B-symptoms such as fever, night sweats, and weight loss, which are indicative of systemic involvement. Staging of follicular lymphoma is crucial for determining treatment options, which may include watchful waiting, chemotherapy, immunotherapy, or stem cell transplantation, depending on the stage and symptoms. Accurate coding is essential for appropriate reimbursement and treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Unspecified site complicates treatment planning.
  • Grade III indicates a more aggressive disease requiring careful staging.
  • B-symptoms may vary, affecting clinical management.
  • Documentation must clearly differentiate from other lymphoma types.

Audit Risk Factors

  • Inadequate documentation of symptoms.
  • Failure to specify the site of the lymphoma.
  • Misclassification of lymphoma grade.
  • Lack of staging information.
