PC/TC indicators

Centers for Medicare & Medicaid Services (CMS) PC/TC indicators are found in the CMS National Physician Fee Schedule Relative Value File. Values which are currently in the CMS file are:

0 Physician service only codes. The concept of PC/TC does not apply.

1 Diagnostic tests for radiology services. Both modifiers 26 and TC can be used with these codes.

2 Professional component only codes. Modifiers 26 and TC cannot be used with these codes.

3 Technical component only codes. Modifiers 26 and TC cannot be used with these codes.

4 Global test only codes. These are selected diagnostic tests that describe a) the professional component of the test only, and b) the technical component of the test only. Modifiers 26 and TC cannot be used with these codes.

5 Incident to codes. These are services covered incident to a physician’s service when provided by auxiliary personnel employed by and working under physician. Modifiers 26 and TC cannot be used. Services cannot be paid when they are rendered to patients in inpatient or outpatient hospital setting.

6 Laboratory physician interpretation codes. Actual performance of the test is paid under the lab fee schedule. Modifier TC cannot be used. Physician performing interpretations of these codes must be billed with modifier 26. These services can be paid under the physician fee schedule if they are furnished to a patient by a hospital pathologist or an independent laboratory.

7 Physical therapy service, for which payment may not be made when the service is billed by an independently practicing physical or occupational therapist to a patient in an inpatient or outpatient hospital setting.

8 Physician interpretation codes. This identifies the professional component of clinical laboratory codes for which a separate payment may be made only if the physician interprets an abnormal smear for hospital inpatient.

9 Not applicable. The concept of TC/PC does not apply.

Policy Statement

CMS designates which procedure codes are valid for use with modifier 26 and modifier TC. Our health plan utilizes these CMS designations in determining procedure code/modifier combinations that are valid for our use. Procedure code/modifier combinations that are considered not valid for our health plan’s use will be denied.

In the event there is a conflict between CMS and the American Medical Association (AMA), our health plan reserves the right to modify the CMS guidance for non-Medicare Advantage plans.

Correct coding guidelines require that modifier 26 be used when the service provided represents only the professional component of a global service and not the equipment or facility component of the same service.

Modifier 26 must be reported with codes having a CMS PC/TC indicator of 1 by the interpreting physicians or other health care professionals if the service is performed in a CMS defined facility place of service setting. The facility will be reimbursed for the technical component portion of the service unless otherwise limited in the facility contract.

Correct coding guidelines require that modifier TC be used when the service provided represents only the equipment or facility component of a global service and not the professional component of the same service. Hospitals frequently provide only the technical component of some services. Hospitals are not currently required to submit the TC modifier but will be reimbursed as if the TC had been billed.

A global procedure code should be reported when a single provider or entity performs both the professional and technical components of a given service.

Appropriate use when adding modifier 26:

When billing only the professional component portion of a test.
To report the physician’s interpretation of a test.
Procedures that have a CMS PC/TC indicator of “1”.

Appropriate use when adding modifier TC:

When billing only the technical component of a test.
Procedures that have a CMS PC/TC indicator of “1”.

Examples of appropriate coding:

Codes 88305, 88311 and 88313 are PC/TC indicator 1 indicating it can be reported as a global code, or separately with modifiers 26 and TC.

Code 88305, 88311, and 88313 when the facility or professional provides the global service.
Code 88305-TC, 88311-TC and 88313- TC when the technical component only is provided.
Code 88305-26, 88311-26 and 88313-26 when the professional component only is provided.

Codes 88184 and 88185 are PC/TC indicator 3 indicating they are technical component only codes and no modifier should be attached.
