R395 – Construction glenoid fossa and zygomatic arch (Obwegeser technique)
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Construction of the glenoid fossa and zygomatic arch, performed using the Obwegeser technique. As per the note on page , this service includes the harvesting and grafting of bone or cartilage grafts.
When to Use
- Use R395 for the reconstruction of the glenoid fossa and zygomatic arch specifically utilizing the Obwegeser technique for temporomandibular joint (TMJ) pathology.
- Use this code when the procedure involves the necessary harvesting and grafting of autogenous bone or cartilage, as these components are inclusive to the fee.
Common Pitfalls
- Do not bill separately for the harvesting of bone or cartilage grafts, as the R395 fee explicitly includes these services per the Schedule of Benefits.
- Avoid unbundling components of the Obwegeser technique; attempting to bill secondary musculoskeletal repair codes alongside R395 will result in rejection for duplicate or inclusive billing.
Billing Tips
- Ensure the operative report clearly details the Obwegeser technique to support the use of this specific code over more generic reconstructive codes like R389 or R396.
- Apply age-based premiums (e.g., AGE_PREMIUM_LT_16Y) if the patient meets the criteria, as R395 is a surgical procedure listed in the eligible sections of the Schedule.
