R899 – Thoraco-abdominal aneurysm – second surgeon
OHIP Radiology Code · Schedule of Benefits
Thoraco-abdominal aneurysm - repair or excision with graft, performed as a two-surgeon procedure (second surgeon).
When to Use
- Use R899 when the complexity of a thoraco-abdominal aneurysm repair necessitates a second primary surgeon to assist in the procedure, provided the first surgeon bills R898.
- Use this code specifically for the second surgeon's component when the surgical team structure is formally designated as a two-surgeon procedure rather than a surgeon-assistant model.
Common Pitfalls
- Billing R899 when the second physician is acting as a surgical assistant rather than a co-primary surgeon, which will result in a rejection or audit recovery.
- Attempting to bill R899 alongside R803, which is strictly prohibited as R803 is reserved for single-surgeon procedures.
- Failure to ensure the first surgeon has successfully submitted R898, as the Ministry cross-references these claims to validate the two-surgeon requirement.
Billing Tips
- Always append the suffix 'A' to R899 and ensure the operative report clearly delineates the specific contributions of both surgeons to justify the two-surgeon billing status.
