E942 – Cantholysis
OHIP Surgical Assists Code — OCULAR SURGICAL PROCEDURES · Schedule of Benefits
Cantholysis, when performed in conjunction with E222 (Primary closure of full thickness lid defect).
When to Use
- Use E942 specifically when performing a lateral cantholysis to mobilize the eyelid tissue during a reconstruction procedure coded as E222.
- Apply this code when the surgical release of the lateral canthal tendon is required to achieve tension-free closure of a full-thickness lid defect.
Common Pitfalls
- Billing E942 as a standalone procedure is incorrect; it must be billed in conjunction with E222 to be eligible for payment.
- Attempting to claim E942 for simple lid laceration repairs that do not involve the formal mobilization of the canthal tendon will result in rejection.
Billing Tips
- Ensure the operative report explicitly details the release of the lateral canthal tendon to justify the use of E942 alongside the primary closure code E222.
