F142
F142 – Orbit with maxilla - with wiring and local fixation
OHIP Anaesthesia Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Open reduction of an orbit with maxilla fracture, performed with wiring and local fixation. This procedure has 6 basic units for a surgical assistant and 7 basic units for an anaesthesiologist.
When to Use
- Use F142 for open reduction of orbital and maxillary fractures requiring internal fixation via wiring and local hardware.
- Select F142 when the surgical approach involves direct exposure and stabilization of the orbit and maxilla, distinguishing it from simpler closed reductions or isolated orbital floor repairs like F150.
Common Pitfalls
- Failing to append E932 for unilateral or E935 for bilateral procedures, which are essential add-ons for F142 to reflect the scope of the repair.
- Billing E830 for mini-plates without specifying the number of major fracture lines, as E830 is payable per major fracture line per side.
- Attempting to bill E932 or E935 alongside restricted codes like Z263-Z266 or E975-E976, which will trigger an automatic rejection.
Billing Tips
- Always itemize E830 for each distinct major fracture line (e.g., infraorbital, malar-zygomatic) to ensure full procedural compensation.
- Confirm the Injury Severity Score (ISS) is documented in the chart if claiming the E420 trauma premium, as this is a frequent audit target for maxillofacial surgical claims.
