E746
E746 – Sigmoidoscopy performed outside hospital
OHIP Surgical Assists Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E746 when performing a flexible sigmoidoscopy (Z535) in a private office or clinic setting rather than a hospital facility.
- Apply this premium when billing for a rigid sigmoidoscopy (Z536) or a sigmoidoscopy with biopsy (Z592) conducted in an out-of-hospital premises.
Common Pitfalls
- Billing E746 for procedures performed within a hospital facility will result in automatic rejection, as the premium is strictly for non-hospital settings.
- Attempting to bill E746 alongside Z535 while also claiming Z555 or Z580 will trigger a rejection due to explicit billing restrictions.
- Failure to link E746 to the primary procedure code (Z535, Z536, or Z592) in the same claim submission will lead to payment errors.
Billing Tips
- Ensure the facility location indicator on your claim reflects an out-of-hospital setting to support the validity of the E746 premium.
