Modifier 26: Professional Component Billing
Modifier 26 indicates the professional component of a service. Learn when to use modifier 26, how it differs from modifier TC.
When to Append Modifier 26
Append to a procedure code (typically radiology or diagnostics) when the physician provides only the interpretation and report, not the technical performance of the test. Use when the technical component (TC) is billed separately by the facility.
- A formal written interpretation and report must exist in the medical record.
- The report must be physician-authored and signed.
- Billing the global code (without 26 or TC) when services are split between physician and facility - causes duplicate billing and claim denial.
