R511 – Mandibular or maxillary visor osteotomy for alveolar hypoplasia
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R511 is a total U dento-alveolar osteotomy, specifically a mandibular or maxillary visor osteotomy for alveolar hypoplasia. This is a surgical procedure listed under the Orthognathic Surgery sub-section of the Musculoskeletal System. As a surgical service, payment includes all constituent and common elements as defined in the Schedule of Benefits (, ). The fee is for the surgeon's service (suffix A), with separate calculations for assistant (suffix B) and anaesthetist (suffix C) services based on unit values.
When to Use
- Use R511 for a total dento-alveolar visor osteotomy specifically indicated for the correction of alveolar hypoplasia.
- Select R511 when performing a segmental or total alveolar repositioning that does not meet the criteria for a full Le Fort I (R502) or sagittal split osteotomy (R507).
Common Pitfalls
- Billing R511 in conjunction with R502 or R507 for the same arch will trigger a rejection for duplicate or overlapping surgical services.
- Attempting to bill for a second surgical assistant without prior authorization from a medical consultant, as R511 is not on the pre-approved list for dual assistance.
Billing Tips
- Ensure the operative report explicitly documents the 'visor' technique to justify the use of R511 over more common orthognathic codes like R502 or R507.
