Professional and technical components
Many diagnostic tests and radiology services can have both a professional component and a technical component. Under Medicare Physician Fee Schedule indicators, services designated for component billing may allow modifier 26 for the professional component and TC for the technical component. Not every diagnostic code permits those modifiers.
| Component | Operational question |
|---|---|
| Professional | Who performed and documented the interpretation/report? |
| Technical | Who supplied the equipment, technician and technical resources? |
| Global | Did one billing entity furnish both billable components? |
Cardiology examples
ECG, ambulatory monitoring, stress testing and imaging can involve separate technical and interpretation workflows. Before billing, confirm which entity performed each component, that the required report exists, and that the code's payment-policy indicator supports the selected billing method.
Radiology controls
- Confirm the order/referral requirements that apply.
- Verify authorization for services that require it.
- Confirm medical-necessity support and diagnosis linkage.
- Check place of service and billing entity.
- Verify whether the claim is professional, technical or global.
