F139 – Open reduction, per fracture, to include intermaxillary fixation
OHIP Anaesthesia Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Performs an open reduction for a mandible fracture. This fee is payable per fracture and includes intermaxillary fixation. As this is a '#'-prefixed service, when performed in a hospital, the provision of premises, equipment, supplies, and personnel are funded by the hospital global budget (: ).
When to Use
- Use F139 for the open reduction of a mandible fracture where intermaxillary fixation (IMF) is performed as part of the procedure.
- Use F139 specifically for the surgical management of a mandibular fracture when internal access is required to achieve reduction, distinguishing it from closed reduction procedures.
Common Pitfalls
- Billing F139 in conjunction with restricted codes like Z239 or Z240 will result in an automatic rejection.
- Failure to document the use of a miniplate or internal fixation device when claiming the E828 add-on will lead to audit recovery, as E828 is strictly limited to cases involving rigid internal fixation.
- Attempting to bill F139 for maxillary fractures is incorrect; F139 is specific to the mandible, whereas other codes in the F-series (e.g., F140) apply to maxillary or complex facial fractures.
Billing Tips
- Always append the E828 add-on code for each major fracture line treated with a miniplate to maximize the procedural fee, ensuring the specific fracture site is clearly identified in the operative report.
- When performing multiple fracture repairs, ensure each F139 is billed per fracture, but verify that the total number of claims aligns with the documented number of distinct fracture lines.
