Z735C – Examination and/or dilatation under general anaesthetic
OHIP Psychiatric Code — FEMALE GENITAL SURGICAL PROCEDURES · Schedule of Benefits
This service provides for the examination and/or dilatation of the vagina under a general anaesthetic. It is designated as a sole procedure, meaning other surgical procedures are not typically billed for the same encounter. The service includes the insertion and/or removal of an intrauterine device (IUD) if performed at the same time. This procedure requires an anaesthesiologist, and the anaesthesia fee (Z735C) is calculated based on 6 base units plus time units.
When to Use
- Use Z735 when performing a vaginal examination or dilatation under general anaesthetic as the primary and only surgical procedure for the encounter.
- Use this code for cases involving the insertion or removal of an intrauterine device (IUD) when performed under general anaesthesia, as the fee is inclusive of these services.
Common Pitfalls
- Billing Z735 in conjunction with other surgical procedures will result in a rejection, as it is strictly designated as a sole procedure.
- Attempting to bill a separate IUD insertion or removal fee (e.g., G552) alongside Z735 is a billing error, as these services are included in the Z735 fee.
Billing Tips
- Ensure the anaesthesiologist bills Z735C using the 6 base units plus time, and verify that any applicable age or emergency anaesthesia modifiers are applied to the anaesthetic fee specifically.
