E943 – Releasing rotation flap including cantholysis
OHIP Surgical Assists Code — OCULAR SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E943 when a full-thickness eyelid defect repair (E222) requires a lateral cantholysis to provide the necessary tissue laxity for a rotation flap.
- Apply this code when the surgical plan necessitates a lateral canthotomy and cantholysis to advance the eyelid margin and close a defect that cannot be managed by primary closure alone.
Common Pitfalls
- Billing E943 without an associated E222 claim will result in an automatic rejection as it is strictly an add-on procedure.
- Attempting to bill E943 for simple eyelid reconstruction that does not involve a formal rotation flap or cantholysis will lead to audit recovery.
Billing Tips
- Ensure the operative report explicitly documents both the rotation flap and the cantholysis, as these are mandatory components for claiming the E943 premium.
