Code Description

ICD-10 C82.05 is a billable code used to indicate a diagnosis of follicular lymphoma grade i, lymph nodes of inguinal region and lower limb.

Key Diagnostic Point:

Follicular lymphoma is a type of non-Hodgkin lymphoma characterized by the proliferation of follicle center (germinal center) B-cells. Grade I indicates a low-grade lymphoma with a relatively indolent course. This specific code pertains to cases where the lymphoma is localized to the lymph nodes in the inguinal region and lower limb. Patients may present with painless lymphadenopathy, and the disease can be associated with B-symptoms such as fever, night sweats, and weight loss. Diagnosis typically involves imaging studies, such as CT scans, and biopsy of affected lymph nodes. Treatment options may include watchful waiting, chemotherapy, immunotherapy, or radiation therapy, depending on the stage and symptoms. The prognosis for grade I follicular lymphoma is generally favorable, but careful monitoring is essential due to the potential for transformation to a more aggressive form of lymphoma.

Complexity Factors

  • Specificity of the code to grade I follicular lymphoma
  • Location specificity (inguinal region and lower limb)
  • Differentiation from other lymphoma types
  • Need for accurate staging and documentation of B-symptoms

Audit Risk Factors

  • Inadequate documentation of B-symptoms
  • Failure to specify the grade of lymphoma
  • Misclassification of lymphoma type
  • Insufficient staging information
