I do the billing for physician's side only. I have a retina specialist who performs many lasers. At the time of the visit's he may also perform an intravitreal injection of some sort (67028) He is not injecting anesthesia for the procedure it's usually a drug for the same problem as the laser. When the patient comes back for follow up's he usually does another injection. According to the CCI edits it's not bundled with some of the laser's. What if he performs an injection during post op. Would i bill 67028 with -78, -79 or -58 ??
