F150 – Orbit with maxilla - closed reduction and dental wiring
OHIP Anaesthesia Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
- Surgical Assistant (Suffix B): No base units are assigned for the surgical assistant for this procedure. Fees are calculated based on time units as described in -.
When to Use
- Use F150 for the closed reduction of a zygomatic-orbital fracture involving the maxilla that is stabilized specifically through dental wiring (intermaxillary fixation).
- Select this code when the procedure is limited to closed reduction techniques, as opposed to open reduction with internal fixation (ORIF) which would require codes like F136 or F137.
Common Pitfalls
- Billing F150 in conjunction with E932, E934, or E935 is strictly prohibited by the Schedule of Benefits and will result in automatic claim rejection.
- Attempting to bill this code for open surgical approaches is a common audit risk; ensure the operative report clearly specifies that the reduction was closed and stabilized via wiring.
Billing Tips
- If mini-plates are utilized in addition to the wiring, ensure you bill the appropriate mini-plate fee per major fracture line as permitted by the Schedule notes to maximize the claim value.
- Always verify if the procedure qualifies for the E420 Trauma Premium if the patient meets the specific Injury Severity Score (ISS) thresholds and the documentation is present.
