F101 – Primary prosthesis, femur only
OHIP Anaesthesia Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Open reduction for a femoral neck, trochanteric, or subtrochanteric fracture. This procedure involves the insertion of a primary prosthesis for the femur only, and includes Moore, Thompson, Unipolar, or Bipolar type prostheses. This is a surgical procedure and is eligible for surgeon (A), assistant (B), and anaesthetist (C) fees.
When to Use
- Use F101 for the insertion of a unipolar or bipolar prosthesis specifically for femoral neck, trochanteric, or subtrochanteric fractures.
- Select F101 when the procedure is limited to the femur and does not involve acetabular reconstruction or total hip arthroplasty, which would fall under different codes.
Common Pitfalls
- Billing F101 in conjunction with E420 (Trauma Premium) is a common error, as these are mutually exclusive with after-hours premiums.
- Confusing F101 with total hip arthroplasty codes; F101 is strictly for the femoral component in the context of specific fracture types.
Billing Tips
- Ensure the surgical report explicitly documents the type of prosthesis used (e.g., Moore, Thompson, Unipolar, or Bipolar) to support the use of F101 over other musculoskeletal codes.
- Always verify if the procedure qualifies for E409 or E410 based on the exact start time of the surgery, as these premiums significantly increase the base fee.
