OHIP Psychiatric Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Surgical procedure for the application of two dental arch bars, or splints, for facial osteotomy. This procedure is billable by the surgeon (suffix A), an assistant (suffix B), and an anaesthetist (suffix C). The fee for the assistant and anaesthetist is calculated based on basic units plus time units. According to the note on , this service includes the harvesting and grafting of bone or cartilage grafts.
When to Use
- Use Z240 when applying two dental arch bars or splints specifically as a component of a facial osteotomy procedure.
- Use this code for the stabilization of the maxilla and mandible during orthognathic surgery where intermaxillary fixation is required.
Common Pitfalls
- Do not bill separately for bone or cartilage harvesting or grafting; these are explicitly included in the Z240 fee per N32.
- Avoid billing Z240 for simple fracture stabilization if the procedure is not part of a facial osteotomy, as this may lead to audit scrutiny regarding the scope of the code.
- Ensure the operative report clearly details the application of two arch bars, as billing for only one bar or a different fixation method will result in a mismatch with the code definition.
Billing Tips
- Ensure the operative report explicitly documents the surgical necessity of the arch bars in the context of the facial osteotomy to satisfy GP8 requirements.
- When billing for assistants or anaesthetists, ensure the time units are accurately recorded, as the total fee for these providers is calculated based on basic units plus time.
