OHIP Radiology Code · Schedule of Benefits
Thoracic aorta aneurysm - repair or excision with graft - Two Surgeon - ascending aorta – first surgeon
When to Use
- Use R890 when performing a thoracic aorta aneurysm repair or excision with graft on the ascending aorta specifically requiring two surgeons, as opposed to the single-surgeon code R799.
- Select this code when the procedure involves complex graft placement or reconstruction where the surgical workload necessitates a co-surgeon (R891) to share the primary operative burden.
Common Pitfalls
- Billing R890 without ensuring the second surgeon has submitted R891, which can trigger audit flags regarding the necessity of a two-surgeon procedure.
- Incorrectly billing R890C for the anaesthesiologist when a pump is used; you must use E650C (28 units) instead of the standard 20 units associated with R890C.
- Failing to add E667 when the procedure is performed for a ruptured aneurysm, as this is a distinct, payable add-on that is often missed.
Billing Tips
- Ensure the primary surgeon uses the suffix 'A' (R890A) and the assistant uses 'B' (R890B) to correctly delineate roles and prevent payment processing errors.
- Always verify that the second surgeon is billing R891A, as R891 is ineligible for assistant or anaesthesia units, making the distinction between R890 and R891 critical for total claim accuracy.
