Neoplasm of uncertain behavior of larynx

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A growth in the larynx (voice box) that cannot yet be classified as cancer or benign. Further evaluation is needed to determine the tumor's potential behavior.

Coding Tips

  • •Laryngeal biopsies often result in uncertain behavior diagnoses; ensure pathology documentation supports this classification
  • •Consider whether the growth affects vocal cord function, as this may impact clinical management

Excludes 1 — Do NOT code together

  • neoplasm of uncertain behavior of aryepiglottic fold or interarytenoid fold NOS (D37.05)
  • neoplasm of uncertain behavior of hypopharyngeal aspect of aryepiglottic fold (D37.05)
  • neoplasm of uncertain behavior of marginal zone of aryepiglottic fold (D37.05)
