Key Takeaways
- Physician billing covers the professional component: the physician’s exam, interpretation, judgment, and written report.
- Facility billing covers the technical component: the equipment, technicians, supplies, and overhead used to deliver the service.
- Modifier 26 reports the professional component only. Modifier TC reports the technical component only. No modifier means one entity is billing both as a global service.
- Physician claims are typically submitted on a CMS-1500 form. Facility claims are typically submitted on a UB-04 form.
- The same CPT code can pay differently depending on whether the service happened in a physician’s own office or in a facility.
- Mismatched modifiers and place-of-service codes are a common, preventable source of denials for facility-based physicians.
Physician billing and facility billing get talked about as if they’re two names for the same thing, but they’re two different claims for two different halves of the same procedure, and mixing them up is one of the more common ways a clean claim still gets denied.
What Physician Billing Covers
Physician billing reports the professional component of a service: the physician’s exam, supervision, interpretation of results, clinical judgment, and written report. It’s billed on a CMS-1500 form, or electronically as an 837P. When a physician-owned practice provides both the equipment and the clinical work, no modifier is needed and the practice bills the full global service. When the physician performs only the interpretation, using equipment or space they don’t own, modifier 26 reports the professional component alone.
What Facility Billing Covers
Facility billing reports the technical component: the equipment, technicians, supplies, room, and overhead required to actually perform the procedure. Hospitals bill this on a UB-04 form, or electronically as an 837I, and Medicare treats a UB-04 claim as covering the technical component by default, so hospitals generally don’t append a separate modifier for it. Modifier TC is used mainly by non-hospital facilities and independent diagnostic testing facilities billing on a CMS-1500 instead.
How Modifiers 26 and TC Split a Single Procedure Code
Not every CPT code can be split this way. CMS publishes a PC/TC indicator for each code in the Medicare Physician Fee Schedule, and only codes flagged as splittable can be billed with modifier 26 or TC. For a splittable code:
- Modifier 26 reports the professional component only, billed by the interpreting physician
- Modifier TC reports the technical component only, billed by whoever owns the equipment and staff
- No modifier reports the full global service, billed when one entity performed both components
The same procedure code, in other words, can turn into two separate claims from two separate entities, or one claim from a single entity, depending entirely on who actually did what.
Why the Same Service Can Pay Differently Depending on Where It Happens
Place of service changes the payment amount, not just the paperwork. Under the Medicare Physician Fee Schedule, a professional service performed in a facility pays at a lower facility rate, because the facility is already being paid separately to cover the overhead. The same service performed in a physician’s own office pays at a higher non-facility rate, since the practice is absorbing that overhead itself. Billing the wrong place-of-service code can mean a denial, or getting paid the wrong amount even when the claim is accepted.
Where This Commonly Causes Denials
Most of the denials that trace back to this split follow a small set of patterns: a physician appending modifier TC for equipment they don’t actually own, a facility-based interpretation submitted with no modifier at all, or a place-of-service code that doesn’t match the modifier on the claim. Denial patterns like these tend to cluster around read-heavy specialties, cardiology, radiology, and pathology in particular, where the physician and the facility are frequently different entities billing the same procedure code. A pre-submission claim scrubber is built to catch exactly this kind of mismatch before a payer ever sees the claim.
Getting the professional and technical split right on every claim is exactly the kind of detail PGM’s physician billing services are built to catch, whether a practice bills globally, splits components with facilities, or works across multiple sites of service.

Frequently Asked Questions About Physician and Facility Billing
What claim form do physicians use versus facilities?
Physicians typically bill on a CMS-1500 form, or its electronic equivalent, the 837P. Facilities typically bill on a UB-04 form, or its electronic equivalent, the 837I. The form itself signals which side of the service is being billed.
Can one provider bill both the professional and technical component?
Yes, when the same entity performs both, no modifier is needed and the full global service is billed on a single claim. Splitting into modifier 26 and modifier TC only applies when two different entities are each billing their own portion.
Does Medicare pay less for a service performed in a facility?
For the professional component, yes. The Medicare Physician Fee Schedule pays a lower facility rate for services performed in a facility setting and a higher non-facility rate for services performed in a physician’s own office, because the facility is separately reimbursed for the overhead in the first case.
How can a practice tell whether a code can even be split this way?
Check the PC/TC indicator listed for that code in the CMS Medicare Physician Fee Schedule Relative Value File. Only codes flagged as splittable can carry modifier 26 or TC at all. Appending either modifier to a code that isn’t splittable is its own, separate trigger for rejection, distinct from using the right modifier on the wrong claim.
Is physician billing the same as medical billing in general?
Physician billing is a subset of medical billing focused specifically on the professional component and CMS-1500 claims, as distinct from facility or institutional billing.
