Code Description

ICD-10 C82.42 is a billable code used to indicate a diagnosis of follicular lymphoma grade iiib, intrathoracic 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. Grade IIIb indicates a more aggressive form of the disease, where there is a predominance of large cells, often leading to a poorer prognosis compared to lower grades. The designation 'intrathoracic lymph nodes' specifies that the lymphoma is primarily affecting lymph nodes located within the thoracic cavity, which can include mediastinal and hilar nodes. Patients may present with B-symptoms such as fever, night sweats, and weight loss, which are indicative of systemic involvement. Diagnosis typically involves imaging studies, such as CT scans, and biopsy of affected lymph nodes. Treatment protocols often include chemotherapy regimens, immunotherapy, or targeted therapies, depending on the stage and overall health of the patient. The management of follicular lymphoma requires a multidisciplinary approach, including oncologists, radiologists, and pathologists, to ensure optimal patient outcomes.

  • Management of B-symptoms and their documentation
  • Variability in treatment protocols based on patient health and disease stage

Audit Risk Factors

  • Inadequate documentation of B-symptoms
  • Failure to specify the grade of lymphoma
  • Misclassification of lymph node involvement
  • Lack of supporting imaging studies in the medical record
