M107 – Total sternectomy
OHIP Ophthalmology Code — RESPIRATORY SURGICAL PROCEDURES · Schedule of Benefits
Total sternectomy is a major surgical procedure for the complete removal of the sternum. This service includes the work of the surgeon, as well as separate fees for an assistant and anaesthetist. - The assistant fee (M107B) is calculated based on 9 basic units plus time units. See and for calculation details. - The anaesthetist fee (M107C) is calculated based on 13 basic units plus time units. See and for calculation details. The fee for the surgical procedure includes pre-operative and post-operative care for up to two weeks, as outlined in the Surgical Preamble ().
When to Use
- Use M107A for the definitive surgical removal of the sternum, typically indicated for deep sternal wound infections or malignancy.
- Select M107A over M106 or M108 when the procedure involves the complete excision of the sternum rather than partial debridement or sternal closure procedures.
Common Pitfalls
- Failing to bill the first two post-operative visits and the day of discharge visit separately, as these are excluded from the M107A global fee.
- Incorrectly applying the 15% reduction rule for multiple procedures when the second procedure is for a complication of the initial sternectomy rather than a separate condition.
- Neglecting to document the Injury Severity Score (ISS) in the medical record when claiming the E420 trauma premium.
Billing Tips
- Ensure the assistant (M107B) and anaesthetist (M107C) claims are submitted with the appropriate time units, as the base units provided are only the starting point for total compensation.
- Verify that non-elective premiums (E409A/E410A) are only applied when the procedure commences within the specified after-hours windows, as these are strictly time-dependent.
