This service is for the surgical repair or excision of an aneurysm in the arch of the thoracic aorta, which includes the placement of a graft. This is a major cardiovascular surgical procedure. The fee for this procedure includes specific basic units for both the surgical assistant (18 units) and the anaesthesiologist (20 units).

When to Use

Use R800 for open surgical repair or excision of a thoracic aortic arch aneurysm involving graft placement, distinguishing it from endovascular procedures found in section Q13.
Use R800 when the procedure is performed as an elective repair of a non-ruptured arch aneurysm.
Use R800 in conjunction with E667 when the procedure is performed for a ruptured thoracic aortic aneurysm.

Common Pitfalls

Failing to document the Injury Severity Score (ISS) in the medical record when claiming the E420 trauma premium, which leads to automatic claim rejection.
Incorrectly billing R800 for endovascular repairs, which are governed by separate codes in section Q13 of the Schedule of Benefits.
Attempting to stack E420 with after-hours premiums (E409, E410); these are mutually exclusive and the system will reject the claim if both are submitted.

Billing Tips

Ensure the E667 add-on code is submitted on the same claim as R800 when the clinical indication is a ruptured aneurysm to capture the additional flat fee.
Verify that the surgical assistant and anaesthesiologist units are correctly applied, as R800 explicitly includes 18 and 20 units respectively, which are factored into the total procedural compensation.
