R462 – Posterior dento-alveolar osteotomy, mandible - one side
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Posterior dento-alveolar osteotomy, mandible - one side is a surgical procedure listed within the Musculoskeletal System section of the Schedule of Benefits under Orthognathic Surgery.
When to Use
- Use R462 for a unilateral posterior mandibular dento-alveolar osteotomy performed as a component of orthognathic correction.
- Use R462 when the surgical scope is restricted to one side of the mandible; use R463 if the procedure is performed bilaterally.
Common Pitfalls
- Billing R462 alongside other mandibular osteotomy codes (e.g., R382 or R383) without clear documentation of separate, distinct surgical sites may trigger a rejection for unbundling.
- Failure to append the correct suffix (A for surgeon, B for assistant) will result in automatic claim rejection, as the fee is specifically defined for these roles.
Billing Tips
- If the patient is under 16 years of age, ensure the appropriate age-based fee premium is applied to the claim to capture the 10-30% increase depending on the exact age bracket.
