You need modifier 24 to separate the E/M service from the global period of the prior surgery, and you also need modifier 25 to show that the E/M service is distinct from the intravitreal injection the ophthalmologist performed that day.
You should also append modifier RT (Right side) to clarify to the carrier that the ophthalmologist is not caring for the eye that previously had surgery. On the claim form, report 99213-24-25-RT.
Don't miss: Append modifier 79 (Unrelated procedure or service by the same physician during the postoperative period) to 67028 (Intravitreal injection of a pharmacologic agent [separate procedure]) to show that the injection was also not related to the earlier surgery. Append RT to 67028 as well.
