R722 – Total anomalous pulmonary venous drainage
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
Total repair of total anomalous pulmonary venous drainage. This is a major cardiovascular surgical procedure performed on the heart and pericardium to correct a congenital defect. The service is eligible for surgeon (suffix A), assistant (suffix B), and anaesthetist (suffix C) claims. Payment for assistant and anaesthetist services is calculated based on basic units plus time units. Anaesthesia services for this procedure have 28 base units. Assistant services have 18 base units.
When to Use
- Use R722A for the complete surgical correction of total anomalous pulmonary venous drainage (TAPVD) in pediatric patients.
- Use this code for the primary repair of the defect; it is not intended for minor revisions or diagnostic procedures.
Common Pitfalls
- Failure to apply the correct age-based premium (e.g., AGE_PREMIUM_LT30D or AGE_PREMIUM_LT1Y) will result in significant underpayment, as these are not automatically calculated by the system.
- Attempting to bill R722A alongside other cardiovascular procedures without explicit documentation of separate incisions or distinct anatomical sites often leads to rejection for unbundling.
Billing Tips
- Ensure the surgical assistant and anaesthetist submit their claims using the same R722 code to ensure the base units (18 for assistants, 28 for anaesthesia) are correctly applied to the time-based calculation.
