R389 – LeFort II maxillary osteotomy and advancement
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R389 is a surgical procedure for LeFort II maxillary osteotomy and advancement. As noted in the Schedule of Benefits on page (), the fee for this procedure includes the harvesting and grafting of bone or cartilage grafts. It is listed under the Musculoskeletal System, within the Skull and Mandible, Orthognathic Surgery subsection.
When to Use
- Use R389 for a formal LeFort II maxillary osteotomy involving the nasal bridge and infraorbital rims for midface advancement.
- Use this code when the procedure includes the harvesting and grafting of autogenous bone or cartilage, as these are bundled into the R389 fee.
Common Pitfalls
- Do not bill separately for bone or cartilage harvesting or grafting; these components are explicitly included in the R389 fee per the Schedule of Benefits.
- Avoid billing R389 for a standard LeFort I (R379) or LeFort III (R395) procedure, as these are distinct surgical codes with different anatomical scopes.
Billing Tips
- Ensure the surgical report clearly details the extent of the osteotomy to justify the use of R389 over less complex maxillary procedures.
