E313 – Exostosis - post auricular approach
OHIP Surgical Assists Code — Y. Ocular and Aural Surgical Procedures · Schedule of Benefits
Surgical procedure for the removal of an exostosis (bony growth) in the ear canal. This procedure is performed using a post-auricular (behind the ear) approach and requires an anaesthetic.
When to Use
- Use E313 specifically for the surgical excision of ear canal exostoses when the post-auricular approach is required for adequate exposure.
- Select E313 when the procedure necessitates general or regional anaesthesia, distinguishing it from minor office-based procedures.
Common Pitfalls
- Billing E313 alongside other ear canal procedures (e.g., E311 or E312) without clear documentation of separate, distinct surgical sites or indications will trigger a rejection for unbundling.
- Failing to recognize that E313 does not include automatic assistant units; billing an assistant without prior authorization from a medical consultant as per GP85 will result in claim denial.
Billing Tips
- If an assistant is required, submit the claim using M400B and ensure the basic units are calculated as 6 plus the total time units to comply with the specific requirements for this procedure.
