R545 – Iliopsoas tenotomy
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R545 is a surgical procedure for the tenotomy (cutting) of the iliopsoas tendon. This procedure is listed in the Musculoskeletal System section of the OHIP Schedule of Benefits, specifically within the 'Pelvis and Hip' reconstruction category. The service is eligible for surgeon (A), assistant (B), and anaesthetist (C) fees.
When to Use
- Use R545 for the surgical release of a tight iliopsoas tendon in patients with hip flexion contractures.
- Use R545 when performing an isolated iliopsoas tenotomy, distinct from more extensive hip reconstruction procedures.
Common Pitfalls
- Billing R545 as a bilateral procedure without using the appropriate bilateral indicator (e.g., modifier 'BI') will result in payment for only one side.
- Attempting to bill R545 in addition to a major hip reconstruction code (e.g., R540) may trigger a 'duplicate service' rejection if the tenotomy is considered an integral component of the primary procedure.
Billing Tips
- Ensure the surgical assistant and anaesthetist fees are calculated using the 6 basic units specified for R545, plus the appropriate time units based on the 15-minute interval tiers.
- Verify that the procedure start time is accurately recorded to correctly apply after-hours premiums (E400B/C or E401B/C) if the surgery commences outside of standard daytime hours.
