R101 – Delay, Small/Intermediate flap
OHIP Radiology Code — INTEGUMENTARY SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
As per the OHIP Schedule of Benefits, R101 is a surgical procedure for the delay of a small or intermediate-sized pedicle flap. This procedure is typically a preparatory stage for a subsequent flap transfer, intended to enhance the viability of the flap tissue by conditioning its blood supply. The fee is for the surgeon (suffix A), with separate calculations for assistant (suffix B) and anaesthetist (suffix C) services based on units.
When to Use
- Use R101 when performing the first stage of a planned multi-stage reconstruction to surgically delay a pedicle flap to improve vascularity before final transfer.
- Use this code specifically for small or intermediate flaps; use R100 for large flaps to ensure correct fee capture.
Common Pitfalls
- Billing R101 on the same day as the definitive flap transfer (e.g., R070 or R071) will trigger a rejection for duplicate service or unbundling.
- Failure to document the specific 'delay' procedure as a distinct surgical stage often leads to audit recovery, as it is frequently mistaken for a simple excision or closure.
Billing Tips
- Ensure the operative report explicitly describes the incision and undermining of the flap margins without full detachment to justify the 'delay' classification over a standard excision code.
