R840 – Bypass graft for haemodialysis - autogenous vein
OHIP Radiology Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This procedure involves creating a vascular access for haemodialysis by constructing a bypass graft with an autogenous vein. This is a surgical procedure typically performed by a vascular or general surgeon. The service includes the surgical procedure itself. Anaesthesia services are billed separately based on a unit system.
When to Use
- Use R840 specifically for the creation of a haemodialysis access using an autogenous vein graft, distinguishing it from synthetic graft procedures like R851.
- Select R840 when performing a primary autogenous bypass graft; if the procedure involves a revision or thrombectomy of an existing graft, use the appropriate revision-specific codes instead.
Common Pitfalls
- Billing R840 alongside R851 for the same vascular access site is a common audit trigger; ensure the procedure strictly matches the autogenous vein definition.
- Failure to document the specific anatomical source of the autogenous vein can lead to claim rejections during manual reviews or audits.
Billing Tips
- Ensure that any associated anaesthesia services are billed separately using the appropriate unit-based anaesthesia codes, as R840 covers only the surgical procedure.
- If the procedure is performed on an emergency basis after hours, verify that the start time is clearly documented to support the application of E409 or E410 premiums.
