Modifier TC- Professional Component

Modifier TC is used when only the technical component of a service is being billed.

What is Modifier TC?

Modifier TC tells insurance payers that the billing provider supplied the equipment, facility, technician, or technical portion of a service.

When to Use Modifier TC

• Only the technical portion is being billed
• The provider supplied equipment or facility resources
• A separate physician billed the professional interpretation
• The service has both professional and technical components

Billing Example

An imaging center performs an X-ray using its equipment and staff, while a separate physician interprets the results. The imaging center may bill the technical component using Modifier TC.

Documentation Tips

• Document the technical service provided
• Confirm who performed the interpretation
• Avoid billing the global service when components are split
• Keep service records and technical details available

Common Denial Reasons

• Duplicate billing with professional component
• Incorrect component billing
• Missing service documentation
• Modifier not allowed by payer
