R388 – Genioplasty - three segments
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R388 is a surgical procedure for genioplasty involving three segments. It is a type of orthognathic surgery performed on the mandible. This procedure is eligible for a surgical assistant service (suffix 'B') with 6 base units and an anaesthesia service (suffix 'C') with 10 basic units, as listed on page of the Schedule. The total fees for assistant and anaesthesia services are calculated by adding time units as described in the General Preamble on pages - and - respectively.
When to Use
- Use R388 specifically for a genioplasty procedure involving the surgical sectioning of the mandible into three distinct segments.
- Select R388 over R386 or R387 when the surgical plan and operative report confirm the creation of three segments, as these codes are differentiated by the number of segments performed.
Common Pitfalls
- Billing R388 without clear documentation of the three-segment osteotomy will lead to audit recovery; the operative report must explicitly describe the three-segment technique.
- Attempting to bill a second surgical assistant without prior authorization will result in rejection, as R388 is not on the pre-approved list for multiple assistants.
Billing Tips
- Ensure the surgical assistant (suffix B) and anaesthesia (suffix C) claims correctly incorporate the base units (6 and 10 respectively) plus the appropriate time units to avoid underpayment.
