E961 – LeFort I advancement - in two segments
OHIP Surgical Assists Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This code represents the additional fee for performing a LeFort I advancement osteotomy in two segments. It must be billed in conjunction with the primary procedure code, R379 (LeFort I advancement in one segment).
When to Use
- Use E961 when the maxilla is surgically divided into two distinct segments during a LeFort I advancement to address transverse deficiencies or arch width discrepancies.
- Apply this code strictly as an add-on when the primary procedure R379 is performed and the surgical plan necessitates a split-segment osteotomy.
Common Pitfalls
- Billing E961 as a standalone procedure will result in an automatic rejection, as it requires the presence of R379 on the same claim.
- Confusing E961 with E962, which is reserved for three-segment osteotomies, will trigger a billing error or audit flag for incorrect complexity coding.
Billing Tips
- Ensure the operative report explicitly documents the division of the maxilla into two segments to justify the additional fee beyond the base R379 procedure.
