Modifier TC is used when only the technical component of a procedure is being billed when certain services combine both the professional and technical portions in one procedure code.
Use modifier TC when the physician performs the test but does not do the interpretation.
The payment for the technical component portion of a test includes the practice expense and the malpractice expense.
Technical component procedures are institutional and cannot be billed separately by the physician when the patient is:
In a covered Part A stay in a skilled nursing facility (SNF) location
This modifier must be reported in the first modifier field.
