Code Description

ICD-10 C82.81 is a billable code used to indicate a diagnosis of other types of follicular lymphoma, lymph nodes of head, face, and neck.

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 C82.81 refers to variants of follicular lymphoma that do not fit into the more common categories. This specific code is used when the lymphoma is localized to the lymph nodes of the head, face, and neck region. Clinically, patients may present with painless lymphadenopathy in these areas. Staging of follicular lymphoma is typically done using the Ann Arbor system, which considers the number of lymph node regions involved and the presence of B-symptoms such as fever, night sweats, and weight loss. Treatment protocols 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 Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and staging of follicular lymphoma
  • Differentiation from other types of lymphomas
  • Need for precise documentation of lymph node involvement
  • Potential for overlapping symptoms with other conditions

Audit Risk Factors

  • Inadequate documentation of lymph node involvement
  • Misclassification of lymphoma type
  • Failure to document B-symptoms
  • Inconsistent staging information

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of follicular lymphoma, improving the accuracy of patient records and treatment plans. C82.81 provides a clear distinction for types of follicular lymphoma localized to the head, face, and neck.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of follicular lymphoma, improving the accuracy of patient records and treatment plans. C82.81 provides a clear distinction for types of follicular lymphoma localized to the head, face, and neck.

Reimbursement & Billing Impact
