F077 – Open reduction - multiple malleoli or ligaments
OHIP Anaesthesia Code — REDUCTION · Schedule of Benefits
Performs the open reduction of an ankle fracture involving multiple malleoli or associated ligaments. As a surgical procedure, this fee includes standard pre-operative and post-operative care. Payment for surgical assistant (F077B) and anaesthetist (F077C) services are calculated separately based on basic and time units as outlined in the General Preamble (-). This service is eligible for various premiums including those for age (), after-hours services (), and trauma ().
When to Use
- Use F077 for open reduction and internal fixation (ORIF) of bimalleolar or trimalleolar ankle fractures where multiple malleoli are addressed.
- Use F077 for ankle fractures involving significant ligamentous disruption requiring open surgical repair, provided it meets the criteria for multiple structures.
- Use F077 when the surgical approach involves the open reduction of complex ankle injuries that exceed the scope of a simple single-malleolar fixation.
Common Pitfalls
- Billing F077 alongside F108 is prohibited as they are mutually exclusive; ensure the correct code is selected based on the specific anatomical involvement.
- Failure to document the specific Injury Severity Score (ISS) in the medical record will result in the rejection of the E420 trauma premium.
- Incorrectly billing F077 for closed reductions; this code is strictly for open procedures, and closed reductions must be billed under the appropriate reduction codes.
Billing Tips
- Always verify if the procedure qualifies for after-hours premiums (E409 or E410) based on the exact start time of the surgery to maximize the procedural fee.
- When billing for a surgical assistant, ensure F077B is submitted on the same claim as F077 to ensure proper unit calculation and payment processing.
