F137 – Nasal bones - open reduction
OHIP Anaesthesia Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use F137 for open reduction of nasal bone fractures requiring surgical exposure, distinct from the closed reduction procedure billed under F136.
- Use F137 when the procedure includes necessary manipulation of the nasal septum in conjunction with the open reduction of the nasal bones.
Common Pitfalls
- Billing E825 for internal fixation without documenting the specific major fracture lines treated, which is required for audit compliance.
- Attempting to bill F137 for a closed reduction, which must be billed as F136; F137 is strictly for open surgical approaches.
- Incorrectly applying E825 as a flat fee per surgery rather than per major fracture line per side as specified in the billing schedule.
Billing Tips
- Ensure E825 is billed for every major fracture line addressed with a miniplate, as this is a per-line, per-side add-on code.

The add-on code E825 for miniplates is described with an associated note on page : 'Where mini-plate(s) are used, one mini-plate fee per each major fracture line (e.g. infraorbital, malar-zygomatic, nasal-frontal, LeFort I, LeFort II and III) (per major fracture line per side) should be billed.' Although this note is positioned under codes F143 and F144, it clarifies the use of miniplate add-on codes generally.
