R941 – Thrombectomy, by open technique
OHIP Radiology Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Thrombectomy by open technique as part of the revision or repair of an arterio-venous (AV) fistula or graft used for haemodialysis.
When to Use
- Use R941 when performing an open surgical thrombectomy specifically to restore patency to an AV fistula or graft for haemodialysis.
- Select R941 when the procedure involves an open incision to remove a thrombus, rather than percutaneous or endovascular intervention.
Common Pitfalls
- Do not bill R941 in combination with R942, R943, R944, R945, or R946, as only one of these codes is eligible for payment per patient per day.
- Avoid billing R941 if the procedure was performed via a percutaneous approach, as this code is strictly defined for open surgical techniques.
Billing Tips
- Ensure you correctly calculate and bill the surgical assistant and anaesthesia units, as R941 carries specific basic unit values (7 for assistants, 10 for anaesthesia) plus time-based units.
- Apply after-hours premiums (E409, E410) or age-based premiums if the patient meets the specific criteria, as these are valid add-ons for this surgical procedure.
