R463 – Posterior dento-alveolar osteotomy, mandible - both sides
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R463 is a surgical procedure for a posterior dento-alveolar osteotomy of the mandible, performed on both sides. This procedure is classified under orthognathic surgery. The fee for the surgeon (suffix A) is a flat rate. The fee for an assistant (suffix B) is based on 6 basic units plus time units. The fee for an anaesthetist (suffix C) is based on 15 basic units plus time units.
When to Use
- Use R463 when performing a bilateral posterior dento-alveolar osteotomy of the mandible to correct malocclusion or skeletal deformity.
- Select R463 specifically when the procedure involves both sides of the mandible; do not use R462 (which is for a single side) if the bilateral requirement is met.
Common Pitfalls
- Billing R463 in conjunction with other mandibular osteotomy codes for the same anatomical site, which will trigger a rejection for duplicate or overlapping services.
- Failing to document the bilateral nature of the procedure, which is a requirement for the R463 flat rate fee.
Billing Tips
- Ensure the surgical report clearly specifies that the osteotomy was performed on both sides of the mandible to justify the use of R463 over R462.
