TC |
Technical component: Under certain circumstances a charge may be made for the technical component alone. Under those circumstances the technical component charge is identified by adding modifier TC to the usual procedure code number. Note for ASCs: This modifier must be reported for facility charges associated with HCPCS codes that have both a technical and professional component (e.g., radiology services) under the Medicare Physician Fee Schedule (MPFS). |

Reduced services: Under certain circumstances a service or procedure is partially reduced or eliminated at the physician’s discretion. Under these circumstances the service provided can be identified by its usual procedure number and the addition of the modifier 52, signifying that the service is reduced. This provides a means of reporting reduced services without disturbing the identification of the basic service. |
