H61.811
BillableExostosis of right external canal
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A benign bony growth (exostosis) in the right external ear canal, often caused by repeated cold water exposure or chronic irritation.
Coding Tips
- •Confirm laterality is right; exostosis is often bilateral in swimmers, so check for bilateral involvement
- •Document if symptomatic (hearing loss, cerumen impaction) versus asymptomatic for clinical context
