Modifier 66

Team Surgeons - Surgical Team

If a team of surgeons (more than 2 surgeons of different specialties) is required to perform a specific procedure, each surgeon bills for the procedure with a modifier 66. Sufficient documentation must establish that a team was medically necessary. All claims for team surgeons must contain sufficient information to allow pricing "by report."
