OHIP Radiology Code · Schedule of Benefits
descending aorta with or without temporary shunt – first surgeon
When to Use
- Use R894 for the primary surgical repair of a descending thoracic aortic aneurysm or dissection when the procedure involves the descending aorta.
- Apply this code when performing a repair that requires the use of a temporary shunt to maintain distal perfusion during the cross-clamping phase.
Common Pitfalls
- Do not bill R894 in conjunction with R895, as the latter is intended for thoracoabdominal aortic procedures and represents a distinct anatomical scope.
- Failing to append the E667 add-on code when the procedure is performed for a ruptured aneurysm results in significant under-billing of the surgical complexity.
Billing Tips
- Always verify if the case qualifies for the E667 surcharge, as it is specifically designed to compensate for the emergent nature and increased technical difficulty of a ruptured descending aorta repair.
