Ophthalmic Coding Specialist Study Questions

Answer: B - When you append modifier -TC to a service, you are indicating that the provider only performed the technical component of the service. Some CPT codes have two components to them, such as radiology services. The professional component of the service is the supervision and interpretation of the x-ray results, whereas the technical component is actually taking the x-ray picture. Sometimes it is necessary to indicate that the physician only performed one or the other part of the service.
