E168 – Biopsy (posterior exposure)
OHIP Surgical Assists Code — OCULAR SURGICAL PROCEDURES · Schedule of Benefits
E168 is a surgical procedure for a biopsy of a tumour or foreign body from the orbit using a posterior exposure approach. The fee for the surgeon is specified, and the anaesthesiologist's fee is calculated based on 6 base units plus time units. Payment for a surgical assistant requires special authorization by a medical consultant.
When to Use
- Use E168 when performing a biopsy of an orbital tumor or foreign body specifically requiring a posterior exposure approach.
- Select E168 over E165 (Orbitotomy) when the primary clinical intent and procedure performed is the biopsy itself via posterior access.
Common Pitfalls
- Billing E168 with a surgical assistant without prior approval from a medical consultant will result in an automatic rejection.
- Confusing E168 with anterior orbital procedures; ensure the operative report clearly justifies the posterior exposure approach to avoid audit scrutiny.
Billing Tips
- Always document the specific posterior surgical approach in the operative note to support the use of E168 over other orbital biopsy codes.
