R721 – Arterial repair of transposition
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
Arterial repair of transposition of the great vessels. This is a surgical procedure listed in the Cardiovascular Surgical Procedures section of the Schedule of Benefits under Heart and Pericardium. The procedure has 18 basic units for a surgical assistant and 28 basic units for anaesthesia.
When to Use
- Use R721 exclusively for the arterial switch operation (Jatene procedure) performed to correct transposition of the great arteries.
- Select R721 when the primary surgical objective is the anatomical correction of the great vessels, distinguishing it from the physiological repair procedures coded under R720.
Common Pitfalls
- Billing R721 in conjunction with other cardiac repair codes (such as R720 or R722) without clear documentation of distinct, separate procedures will trigger an automatic rejection for unbundling.
- Failing to secure prior authorization for a second surgical assistant will result in the denial of the second assistant's claim, as R721 is strictly limited to one assistant unless medically justified.
Billing Tips
- Ensure the surgical report explicitly details the coronary artery reimplantation, as this is a critical component of the R721 procedure that justifies the complexity of the fee.
