R382 – Anterior dento-alveolar osteotomy, maxilla or mandible - one segment
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Performs an anterior dento-alveolar osteotomy on either the maxilla (upper jaw) or mandible (lower jaw), involving a single segment. This is a surgical procedure listed under and classified under orthognathic surgery to correct dental and jaw misalignments. The fee is for the surgeon's service (suffix A), with separate calculations for assistant (suffix B) and anaesthesiologist (suffix C) services based on unit values.
When to Use
- Use R382 for a single-segment anterior dento-alveolar osteotomy when the surgical plan is limited to one specific segment of the maxilla or mandible.
- Select R382 for corrective orthognathic procedures where the scope of the osteotomy does not meet the criteria for multi-segment procedures like R383.
Common Pitfalls
- Billing R382 in conjunction with R383 for the same jaw segment will result in a rejection for duplicate or overlapping services.
- Failure to document the specific segment involved can lead to audit scrutiny, as the code is strictly defined for a single-segment procedure.
Billing Tips
- Ensure the surgical report explicitly identifies the single segment osteotomized to justify the use of R382 over more complex multi-segment codes.
