R747 – Aneurysm of sinus of Valsalva
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
A surgical procedure for the excision of an aneurysm of the sinus of Valsalva. This procedure is eligible for assistant and anaesthesia services, with fees calculated based on basic and time units. Per , a second assistant's service is eligible for payment for this procedure without prior authorization.
When to Use
- Use R747 specifically for the surgical excision of an aneurysm of the sinus of Valsalva.
- Use this code when the procedure is performed as a standalone surgical intervention, distinct from more complex multi-valve or aortic root reconstructions that might fall under different cardiovascular surgical codes.
Common Pitfalls
- Failing to document the specific anatomical location of the sinus of Valsalva aneurysm, which can lead to audit scrutiny regarding the appropriateness of R747 versus other cardiovascular surgical codes.
- Incorrectly calculating surgical assistant units by failing to apply the tiered unit structure (1 unit for the first hour, 2 units up to 1.75 hours, and 3 units thereafter) as defined in the payment adjustment rules.
Billing Tips
- Ensure the second assistant is billed under the same claim as the primary surgeon, as R747 is explicitly eligible for a second assistant without prior authorization per GP90.
- Always verify the start time of the procedure to accurately apply after-hours premiums (E400B/E401B for assistants or E400C/E401C for anaesthesia), as these are calculated based on the case commencement time.
