R588 – Naso-maxillary osteotomy without LeFort I
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
R588 is for a naso-maxillary osteotomy performed without a LeFort I procedure. Per the note on page , this service includes harvesting and grafting of bone or cartilage grafts.
When to Use
- Use R588 for isolated naso-maxillary osteotomy procedures where a full LeFort I osteotomy is not performed.
- Apply this code when the surgical plan involves repositioning the naso-maxillary complex for structural correction without the complete maxillary down-fracture required for a LeFort I.
Common Pitfalls
- Do not bill separately for bone or cartilage harvesting; these are explicitly included in the R588 fee and will be rejected or clawed back if claimed as additional procedures.
- Avoid using R588 if the procedure involves a LeFort I osteotomy, as this would be a miscoding of the surgical extent.
- Failure to document the specific nature of the osteotomy in the operative report is a primary cause for audit recovery, as the distinction from other maxillary procedures must be clear.
Billing Tips
- Ensure the operative report explicitly details the osteotomy sites to justify the use of R588 over other maxillary surgical codes.
- If the patient is under 16 years of age, remember to apply the appropriate age-based premium to the base fee of $803.80 to maximize the claim.
