R733 – Mitral valvuloplasty
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
Mitral valvuloplasty is a cardiovascular surgical procedure for the repair of the mitral valve. As a major surgical service, the fee includes pre-operative, intra-operative, and post-operative care. This service must be rendered personally by the physician or a supervised medical trainee and documented in the patient's medical record as per the requirements outlined in the Schedule of Benefits.
When to Use
- Use R733 for the surgical repair of the mitral valve when the procedure does not involve a full valve replacement.
- Use R733 as the primary procedure code when performing a mitral valvuloplasty in isolation or as the major component of a multi-valve procedure.
Common Pitfalls
- Billing R733 alongside a mitral valve replacement code is incorrect; follow the Schedule of Benefits rules for multivalvular procedures to avoid claim rejection.
- Failing to document the specific ISS score in the medical record when attempting to claim the E420 trauma premium will result in an audit recovery.
- Submitting R733 for a simple valvulotomy or minor repair that may be covered under a different, lower-valued cardiovascular code.
Billing Tips
- When performing multivalvular surgery, bill the major valve procedure at 100% and the additional valve procedures at 85% of their respective fees.
- Ensure that second surgical assistant claims for R733 are submitted clearly, as this code explicitly allows for a second assistant without prior medical consultant authorization.
