R351 – Posterior dento-alveolar osteotomy, maxilla - both sides, single segment
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Posterior dento-alveolar osteotomy, maxilla, both sides, single segment is a surgical procedure listed in the Musculoskeletal System section of the Schedule of Benefits under Orthognathic Surgery. It is claimable with suffixes for surgeon, assistant, and anaesthetist.
When to Use
- Use R351 for a single-segment posterior maxillary osteotomy performed bilaterally to address posterior open bite or vertical maxillary excess.
- Select R351 when the surgical plan involves a single segment mobilization of the posterior maxilla, distinguishing it from multi-segment procedures like R349 which involve the anterior segment.
Common Pitfalls
- Billing R351 alongside other maxillary osteotomy codes for the same segment can trigger rejection for unbundling; ensure the procedure reflects the total surgical scope.
- Attempting to bill for a second surgical assistant without prior medical consultant authorization will result in automatic rejection, as R351 is not on the pre-approved list for second assistants.
Billing Tips
- When performing multiple or bilateral procedures under the same anaesthetic, ensure the basic units for the assistant and anaesthesiologist are calculated based on the major procedure code only.
