Facility fees, explained: why a clinic visit can produce two bills

The short answer, first

Start with the two charges side by side. The professional fee is the charge for the clinician: the time, judgment, examination, procedure, or interpretation the clinician personally provided. The facility fee is the charge for the place: the building, the room, the equipment, the supplies at that site, the support staff who are not the clinician, and the overhead of keeping the location open. In a hospital or hospital-owned outpatient department, those parts are often billed separately, by separate offices, under separate names. In an independent practice, the same overhead usually sits inside a single professional charge, so the patient sees one bill.

Because the parts bill separately, they can also be processed separately. A plan may show two claims for the same date, and it may apply cost sharing to each part, which is why a visit can sometimes produce two cost-sharing amounts as well as two bills. The statements may arrive on different days, from different addresses, with different reference numbers. Read the pair as a pair: same date, same visit, two billing parts. The same service can also bill differently by setting: at a hospital-owned site it can produce a facility charge plus a professional charge, while at an independent office it usually produces the professional charge alone. Our comparison of hospital outpatient departments and imaging centers shows the same split for scans, and why a radiologist bills separately after an MRI, CT or X-ray prices the reading and equipment pieces code by code.

How to tell before an appointment: the overview

You do not need to understand the whole payment system to avoid a surprise. Ask a short set of questions, in order, before the appointment, and hold the answers in writing.

1. Ask who owns the practice or clinic where you will be seen, and whether it is part of a hospital or health system.
2. Ask whether that exact location bills as a hospital outpatient department or a hospital-owned clinic for your type of visit.
3. Ask directly whether a facility fee will be billed in addition to the professional fee.
4. Ask for both charges, not a single combined figure: the expected facility charge and the expected professional charge, named separately.
5. Ask who will send each bill, so you know which names and billing offices to expect afterward.
6. If you have insurance, ask how your plan is expected to process each part, and whether each part can carry its own cost sharing.
7. If you are uninsured or paying yourself, ask for both parts to be listed in your Good Faith Estimate, or in two estimates if the parts are billed by different providers.
8. Check the estimate or written answer before the appointment, confirm that both parts appear, and keep it with the date you received it.

None of these steps argues about whether the fee should exist. Each only asks the office to name, in advance and in writing, a charge it already knows how it bills. A vague answer tells you to keep asking, in writing, before the visit rather than after the bills arrive.

Where the service happens decides how it bills

Where the service happens	How billing usually works	The question to ask
Hospital outpatient department, on campus or elsewhere	Facility fee plus professional fee, often billed and processed as two separate parts	"Will this visit be billed with a facility fee and a professional fee, and can you give me both charges?"
Hospital-owned clinic or practice, including an off-campus site that looks like an office	Often the same split: facility fee plus professional fee, because the billing identity is the hospital	"Who owns this practice, and does this location bill a facility fee for my visit?"
Independent practice that is not owned by a hospital or health system	Usually a professional fee only, with the overhead of the office inside that single charge	"Is this practice independent, and will there be any facility charge in addition to the professional fee?"

Read the table as a pattern, not a promise about any one office. The middle row catches people out. A hospital-owned clinic may keep the name, staff, waiting room, and address it had as an independent practice. From the chair, nothing announces the change. From the billing system, everything has changed, because the site now bills under the hospital. A building does not have to look like a hospital for hospital billing logic to apply: ownership and billing designation, not appearance, decide your row.

The table also explains why price comparisons mislead. Two quotes can look far apart, or suspiciously close, simply because one names both parts and the other names only one. A low quote that is the professional part alone is not a complete quote. Before comparing figures, ask each office: does this number include both parts, and if not, what is the other part and who bills it?

Why hospitals charge facility fees

Hospitals describe facility fees as the way the cost of running the facility itself gets paid, separate from the work of any individual clinician. Stated neutrally, the reasoning runs like this. A hospital site carries costs that exist whether or not a clinician is in the room: the building, the equipment, the support staff, the supplies on hand, the records and scheduling systems, and the cost of keeping a site staffed and open across the day. Those costs have to be accounted for somewhere. The facility fee is the line that accounts for them separately, instead of folding them into the professional charge.

You do not have to accept or reject that reasoning to use this guide. Patients, hospitals, insurers, and policymakers debate facility fees, and this site takes no side. What matters for your appointment is practical: whether the fee applies to your visit, whether you were told before the visit, whether both parts were named in your estimate, and whether the bills match what you were told. The pattern has also spread beyond hospital campuses: when a hospital acquires an independent practice, the site can start billing under the hospital pattern, and the facility layer appears on visits that previously billed as one charge, with the same clinicians in the same rooms. A second bill after such a change is not, by itself, an error. It is evidence the billing identity changed.

One office visit, three Medicare billing setups, in 2026 dollars

Medicare's own payment files show the split with real numbers. Take the most familiar visit code there is, CPT 99213, which the CMS fee schedule file lists as "Office o/p est low 20 min": an established patient's office or outpatient visit at the low level. The fee schedule carries two amounts for it. The nonfacility amount is paid when the visit happens in a physician's office. The facility amount is paid when the patient is a hospital outpatient. The Medicare Claims Processing Manual is explicit about the second case: for an outpatient of a hospital, place of service code 19 (off campus) or 22 (on campus), the facility rate is paid, wherever the face-to-face encounter took place. The hospital then bills its own line for the clinic visit, HCPCS G0463, under the outpatient payment system.

Show the numbers behind this figure

Setting	Line	Payment system	Medicare anchor
Physician office	99213 nonfacility	PFS, Michigan Locality 01	$95.55
On-campus hospital department	99213 facility	PFS, Michigan Locality 01	$59.13
On-campus hospital department	G0463 clinic visit	OPPS, national unadjusted	$136.02
Excepted off-campus department (PO)	99213 facility	PFS, Michigan Locality 01	$59.13
Excepted off-campus department (PO)	G0463 at about 40% of OPPS	PFS-equivalent rate, our arithmetic	$54.41

Three things in that table matter more than the dollar amounts themselves. First, the physician's own line goes down when the visit moves into a hospital department. The RVU file shows why: the work and malpractice values for 99213 are identical in both settings, and the whole difference sits in practice expense, 1.46 units in an office against 0.33 in a facility. The office overhead that the physician no longer carries is the part the hospital bills for separately.

Second, the hospital line is larger than the physician line it travels with. On campus, the G0463 anchor of $136.02 is more than twice the $59.13 physician facility amount. Those two numbers come from different payment systems with different geographic bases, so this guide does not add them into a single "hospital visit price". What can be said is narrower and still useful: a visit that bills under a hospital creates a second claim, and on that second claim Medicare's anchor alone exceeds the whole office-visit anchor.

Third, the off-campus rows show that Medicare itself pays less for the same clinic visit line depending on where the department is and when it started billing, which the next section explains. None of these figures is a commercial or self-pay price. A hospital's charge for G0463, or a plan's allowed amount for it, is set by the hospital's chargemaster and the plan's contract, and can sit far from the Medicare anchor in either direction. Use the anchors to understand the shape of the bill, and get the actual figures for both lines from the billing offices in writing.

How to spot a facility fee on an itemized bill and an EOB

After the visit, the pair of bills is your evidence. Ask each billing office for the itemized statement, and set the statements beside your explanation of benefits, the document your plan sends showing how it processed each claim. The itemized-bill check is the full procedure for reading a statement line by line, and it applies to both parts unchanged. For a facility fee, add these checks.

• Look for two claims or statements for the same date: one from the clinician or practice, one from the hospital or facility.
• On the facility statement, look for a line naming the facility, the department, or the outpatient setting, rather than a clinical service the clinician performed.
• Check the names. The facility bill may carry the hospital or health system name, not the clinic name, and the professional bill may carry a group name you do not recognize.
• On the explanation of benefits, check whether the plan processed the two parts separately, and whether it assigned cost sharing to each part.
• Match both parts against any written quote or estimate you received. A facility line never mentioned, by an office that confirmed a single all-in price in writing, is a question to raise with that answer in hand.
• If the itemized hospital statement shows codes, look for G0463, the hospital outpatient clinic visit, and for a PO or PN modifier beside it. Either modifier means the hospital billed the line from an off-campus department.
• On the physician side, a place of service code can appear on the claim detail: 11 for an office, 19 for an off-campus hospital outpatient department, 22 for an on-campus one. Under the Medicare manual, 19 and 22 mean the physician was paid the lower facility rate, which is consistent with a separate hospital line for the same visit.

Two traps sit inside this check. The first is assuming the second statement is a duplicate and ignoring it, when it is a separate claim that will age on its own schedule. The second is assuming it must be an error, when the accurate question is whether the location bills a facility fee and whether you were told. A fee denied in writing before the visit, appearing twice for one visit, or dated on a day you did not attend, is an accuracy problem. Keep the pair in one folder, and remember each office can correct only its own part.

Questions to ask when you book

The booking call is where a facility fee is easiest to deal with, because nothing has been billed yet and every answer can still be put in writing. Write the answers down with the name of the person who gave them.

• "Who owns this practice or clinic? Is it part of a hospital or a health system?"
• "Does this location bill as a hospital outpatient department or a hospital-owned clinic for a visit like mine?"
• "Will I be charged a facility fee in addition to the professional fee?"
• "What are the expected charges for both parts, and can you send them to me in writing?"
• "Will I receive two bills, and from which names or billing offices will they come?"
• "If I pay without insurance, will both parts be listed in my estimate?"
• "If the location or the billing arrangement changes before my appointment, will you tell me and update the written price?"

If you are comparing settings, ask the same questions at each one and record the answers the same way: facility part, professional part, and an all-in figure built only from parts the office itself named. The cash price guide gives the wording for a complete written cash price. Hospital price transparency postings can help you prepare when the site is a hospital: our guide to hospital price transparency explains where the published charges live and how to turn a posted row into a question for billing. Use a posting to frame your questions, not replace them, because it may not tell you whether your visit will carry a facility part.

Facility fees and Good Faith Estimates for self-pay patients

If you are uninsured, or you choose to pay yourself without using insurance, the written protection is the Good Faith Estimate. Our guide to Good Faith Estimates explains who is entitled to one, what it must list, and the dispute route that can open when a final bill is far above the estimate. The facility fee point is simple: an estimate for a visit at a site that bills a facility fee should list that charge among the expected charges, shown separately from the professional charge when the two bill separately.

Check the estimate when it arrives, before the visit. Does it name both billing parts, or only one? Does it name the location where you will be seen, since the location decides whether the facility part applies? If a part is missing, ask in writing for a revised estimate, and keep both versions with their dates. If the missing part is billed by a different provider, request that provider's own estimate as well. If you are using insurance, you will not receive a Good Faith Estimate of this kind, but the same discipline applies: ask for both parts in writing anyway.

Medicare's site rules: on campus, off campus, PO and PN

Many readers meet the two-part bill first through a Medicare statement, and Medicare is also where the rules about facility fees are written down in the most detail. CMS pays hospital outpatient departments through the Hospital Outpatient Prospective Payment System, usually shortened to OPPS, and pays physicians through the Physician Fee Schedule. That is the two-part structure in its plainest form. Since 2017, though, Medicare has not treated every hospital department alike, and the differences explain why the same clinic visit line can carry different Medicare amounts.

The starting point is section 603 of the Bipartisan Budget Act of 2015. As the CY2026 OPPS final rule summarizes it, items and services furnished from January 1, 2017 by certain off-campus outpatient departments of a hospital are no longer paid under the OPPS but under another Part B payment system, generally the Physician Fee Schedule. The Medicare regulation at 42 CFR 419.48 sets out who is spared, which CMS calls "excepted": a dedicated emergency department; a department on the hospital's campus, or within the distance the rules allow of a remote location of the hospital; and an off-campus department that was furnishing and billing services under the OPPS before November 2, 2015. An off-campus department that opened later is "nonexcepted".

The two kinds of off-campus department mark their claim lines differently, and the modifier tells you which rules applied:

• Modifier PN marks a nonexcepted item or service from a nonexcepted off-campus department. CMS says these are generally paid under the Physician Fee Schedule at the OPPS rate adjusted by a "PFS Relativity Adjuster" of 40 percent, that is, 60 percent less than the OPPS rate.
• Modifier PO marks a service from an excepted off-campus department. These stay under the OPPS, but since the CY2019 rule CMS has paid the clinic visit, G0463, at a PFS-equivalent rate in these departments. The cut was phased in: CMS says these departments were paid approximately 70 percent of the OPPS rate for the clinic visit in CY2019, and from CY2020 the PFS-equivalent rate has been 40 percent of the OPPS payment. CMS describes the policy as a method to control unnecessary increases in the volume of outpatient services, and the CY2027 proposed rule notes that the U.S. Court of Appeals for the D.C. Circuit upheld that reading in American Hospital Ass'n v. Azar, 964 F.3d 1230 (2020). Off-campus departments of rural sole community hospitals have been exempt from it since CY2023.
• From January 1, 2026, the CY2026 rule extends the same PFS-equivalent payment to drug administration services in the APC 569X family furnished in excepted off-campus departments, again with rural sole community hospitals exempted. The drug itself is a separate line paid per unit at the same rate in either setting; the Part B infusion coinsurance guide sets the drug line and the administration line side by side for common infusion codes.

The direction of travel is toward more of the same. In the CY2027 OPPS proposed rule, published in the Federal Register on July 7, 2026, CMS proposed paying the PFS-equivalent rate for imaging without contrast in excepted off-campus departments too. It was a proposal, not a rule, when this guide was checked on October 28, 2026; the final CY2027 rule had not been published. Separately, Congress has acted: as the same proposed rule describes it, section 6225 of the Consolidated Appropriations Act, 2026, enacted February 3, 2026, bars OPPS payment for services furnished on or after January 1, 2028 by an off-campus outpatient department unless the department bills under its own National Provider Identifier, separate from the main hospital's, and the hospital has attested that the department meets the provider-based rules. It is a billing detail, but from that date each off-campus department's Medicare claims are to carry an identifier of its own rather than the main hospital's.

Two limits keep this in proportion. The reduced rates apply to off-campus departments; CMS wrote in the CY2026 rule that over 60 percent of clinic visits under the OPPS are furnished on campus, and that those on-campus visits are not affected by the existing policy. It asked for public comment on extending the policy on campus and has not adopted that. And the rules govern what Medicare pays the hospital. They do not cap what a hospital charges a self-pay patient or what a commercial plan allows, which are set by the hospital and by contract.

For a person with Original Medicare, the setting shows up in cost sharing. Part B coinsurance is generally 20 percent of the Medicare-approved amount, applied to each line separately once the deductible is met. In an office, that is one share on one line. In a hospital department, it is a share of the physician's facility amount plus the hospital's copayment for G0463, whose minimum unadjusted amount is $27.21 on campus in CY2026 before any wage-index adjustment. Your actual share depends on the locality, any supplemental coverage, and how much of the deductible remains, so ask both billing offices for their figures. For the wider arithmetic of what a Medicare patient pays for hospital outpatient care, see what Medicare patients pay for an outpatient procedure.

State notice rules vary

Some states have their own rules about facility fees, including notice rules, limits in particular settings, or disclosure when a practice is hospital-owned. Those rules differ by state and change over time, so this guide does not list them: a partial list read as complete would mislead. Instead, treat the state question as one more check. If a fee surprises you, ask the billing office whether a state notice rule applies and whether any required notice was given. Your state department of insurance can tell you what rules exist where you received care.

If a facility fee appears that you were never told about

Work in the same order as any billing question: documents first, calls second, payment decisions last. Gather the itemized statements for both parts, the explanation of benefits, and any written quote or estimate. Mark the exact disagreement in one sentence: you were quoted a single price in writing and no facility charge was named, the facility line appears twice, or the date or location is wrong. A disagreement stated that precisely can be checked. A general complaint that the bill feels too high cannot.

Then call the office that sent the facility bill, state the sentence, and ask it to explain the line against your documents, or correct it if they show an error. Ask what happens to the account while the question is under review, and get the answer in writing. Call the professional billing office only if its part is also in question; it cannot settle the facility part. Do not ignore the second bill hoping it was a mistake: a separate claim does not disappear because it was unexpected, and a question raised early is far easier to resolve.

Facility fee traps to avoid

• Assuming a clinic that looks like an ordinary office cannot bill a facility fee, when ownership, not appearance, decides the question.
• Comparing a quote naming only the professional part with one naming both, and treating the smaller number as cheaper.
• Accepting a single combined figure without asking whether a facility fee is inside it, and who bills each part.
• Treating the second bill for the same date as a duplicate and ignoring it, when it may be a separate facility claim on its own schedule.
• Treating every facility fee as an error, when the checkable questions are whether the site bills one and whether you were told.
• Letting a self-pay estimate stand with only one part listed, when a missing facility line is quick to fix before the visit.

For surgical codes, Medicare pays a surgery center roughly half of the hospital outpatient facility payment; the figures and the cases where the patient share reverses are in the surgery center comparison.

A facility fee is one of the ten places a high bill with insurance can come from, and that guide shows its effect on a plan's deductible and coinsurance with stated numbers. Therapy is a case where a hospital outpatient department adds no separate facility column to the Medicare schedule, as the physical therapy cost guide shows. A joint injection is the opposite case: in a hospital-owned clinic the hospital line for CPT 20610 is several times the physician's line, as the cortisone shot cost breakdown shows.
