R858 – Removal of infected aortic graft
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
Total removal of an infected aortic graft, including both the stem and the limbs of the graft. This procedure is listed in the Schedule of Benefits under Cardiovascular Surgical Procedures, specifically for Aorto-Iliac repair. A note in the schedule specifies that arterial reconstruction is payable as an extra service. This procedure is eligible for a second surgical assistant without requiring prior authorization. Add-on codes such as E664 (closure of duodenum) and E986 (suprarenal or supraceliac aortic cross clamp) may be payable with this service.
When to Use
- Use R858 for the complete excision of an infected aortic graft, including both the main body and the iliac limbs, typically in the context of graft infection management.
- Use R858 when the surgical plan involves total graft removal, distinguishing it from partial graft revisions or simple bypass procedures.
Common Pitfalls
- Failing to bill E986 when a suprarenal or supraceliac aortic cross clamp is utilized, as this is a distinct, payable add-on for the increased complexity of the procedure.
- Neglecting to bill for arterial reconstruction separately, as the Schedule of Benefits explicitly notes that arterial reconstruction is payable as an extra service in addition to R858.
Billing Tips
- Ensure that if a second surgical assistant is required, you bill for them directly, as R858 is eligible for a second assistant without needing prior authorization from a medical consultant.
