Code Description

ICD-10 C82.83 is a billable code used to indicate a diagnosis of other types of follicular lymphoma, intra-abdominal lymph nodes.

Key Diagnostic Point:

Follicular lymphoma is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. The 'other types' designation in C82.83 refers to variants of follicular lymphoma that do not fit into the more common categories, specifically those that present with lymphadenopathy in the intra-abdominal region. This can include lymph nodes in the mesentery or retroperitoneum. Patients may present with B-symptoms such as fever, night sweats, and weight loss, which are indicative of systemic involvement. Diagnosis is typically confirmed through biopsy and histological examination, often revealing a characteristic follicular pattern. Staging is crucial for treatment planning and involves imaging studies such as CT scans or PET scans to assess the extent of disease. Treatment options may include watchful waiting, chemotherapy, immunotherapy, or stem cell transplantation, depending on the stage and symptoms. The prognosis varies based on the specific characteristics of the lymphoma and the patient's overall health.

  • Potential for overlapping symptoms with other conditions

Audit Risk Factors

  • Inadequate documentation of B-symptoms
  • Failure to document staging and imaging results
  • Misclassification of lymphoma subtype
  • Lack of clarity in treatment plans
