Code Description

ICD-10 C82.26 is a billable code used to indicate a diagnosis of follicular lymphoma grade iii, unspecified, intrapelvic 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 III follicular lymphoma indicates a more aggressive form of the disease, with a higher proliferation index and a greater likelihood of transformation to a more aggressive lymphoma. When classified as 'unspecified,' it indicates that the specific characteristics of the lymphoma have not been detailed in the documentation. In this case, the lymphoma is localized to the intrapelvic lymph nodes, which may include lymph nodes in the pelvic region such as the iliac or inguinal nodes. Patients may present with B-symptoms, which include fever, night sweats, and weight loss, indicating systemic involvement. The staging of follicular lymphoma is crucial for determining treatment options, which may include watchful waiting, chemotherapy, immunotherapy, or radiation therapy, depending on the stage and symptoms. Accurate coding is essential for appropriate treatment planning and reimbursement.

Complexity Factors

  • Variability in documentation of lymphoma grades and types
  • Need for precise staging information
  • Differentiation from other types of lymphomas
  • Potential for transformation to aggressive forms

Audit Risk Factors

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

Specialty Focus

Medical Specialties

Hematology/Oncology

Documentation Requirements

Complete pathology reports, staging information, and treatment plans must be documented.

Common Clinical Scenarios

Patients presenting with lymphadenopathy, B-symptoms, or those undergoing treatment for follicular lymphoma.

Billing Considerations

Ensure that all relevant clinical details, including grade and staging, are clearly documented to support coding.

Radiology

Documentation Requirements

Imaging reports must clearly indicate the location and size of lymph nodes involved.

Common Clinical Scenarios

Imaging studies performed to assess lymph node involvement in patients with suspected lymphoma.

Billing Considerations

Radiology reports should correlate findings with clinical symptoms and pathology results.

Coding Guidelines

Inclusion Criteria

Use C82.26 When
  • Follow the official ICD
  • CM coding guidelines for neoplasms, ensuring that the code is supported by clinical documentation
  • Include details on the grade of lymphoma and any associated symptoms

Exclusion Criteria

Do NOT use C82.26 When
  • Exclude codes for other types of lymphomas or conditions that do not meet the criteria for C82
