Facility fee

What a facility fee is

A facility fee is the payment to the hospital or behavioral health facility for the costs of running the site of care. It covers items like the building, utilities, nursing and tech staff, equipment, supplies, and program infrastructure. It is separate from the professional fee, which pays the individual clinician for the service.

In practice, the facility fee is coded using revenue codes and sometimes facility-specific HCPCS codes on the UB-04, or as a technical component when split-billing a service. In hospital outpatient departments and provider-based clinics, the same visit often generates two claims: a facility claim and a professional claim. The same concept applies in behavioral health programs such as PHP, IOP, and inpatient or residential treatment, where the per-diem or program code functions as a facility fee.

Facility fees are not "extra" in the payer's view. They are a defined component of payment under the contract or fee schedule. For Medicare and many Medicaid programs, outpatient facility services are paid under specific payment systems and fee schedules, separate from the physician fee schedule.

Why facility fees matter operationally

Facility fees are real dollars, and they typically represent the larger share of the reimbursement for hospital-based and residential behavioral health services. Mis-coding or missing a facility fee can cut your revenue for a day of care in half or more, or drop it to zero if the only bill you send is the professional claim.

Incorrect facility billing drives preventable denials and underpayments. Common patterns include billing a facility fee from a non-facility site of service, billing both a facility per-diem and separate revenue codes that the payer treats as bundled, or using the wrong revenue code so the payer prices at a much lower rate. These show up as CO-97, CO-96, or CO-45 adjustments and drag down net collection rate.

Facility fees also drive patient responsibility. For outpatient hospital and many Medicaid managed care plans, the patient may owe separate copays or higher coinsurance on the facility side. If your front desk or financial counseling teams are not clear on the difference, patient estimates will be wrong and your collection at time of service will suffer.

How facility fees show up on claims and in payments

On the claim, the facility fee lives on the institutional side. You will see it as:

• Revenue codes (for example, 090x for behavioral health, 100x for room and board, and other program-related codes) on the UB-04
• Sometimes a facility-level HCPCS or per-diem code that represents the program day, intensive outpatient session, or partial hospitalization day
• Site-of-service and billing-provider details that indicate a hospital or facility, not a private office

The clinician's work is billed as the professional fee on a CMS-1500 with CPT or HCPCS codes, typically using a non-facility rate. Some services can be split into professional and technical components, each with separate reimbursement.

On the remittance advice, you will see the facility fee paid at the contracted rate, often with higher patient cost sharing compared with an office visit. Underpayments can hide in the details: incorrect revenue codes or place of service can cause the payer to apply the wrong fee schedule or bundle the facility fee into another service.

Your contracting and RCM teams need a clear mapping between revenue codes, program types, and contracted rates, so they can validate each remittance and catch when a facility fee is missing, reduced, or bundled unexpectedly.

• Billing a hospital-style facility fee for services rendered in a freestanding outpatient clinic (POS 11) and getting hit with CO-4 or CO-97 because the payer only covers a professional fee in that setting.
• Using a generic revenue code for behavioral health days (for example, 0910) when the contract expects a specific revenue code and per-diem HCPCS for IOP or PHP, which causes the payer to price at a low default rate and write off the difference as CO-45.
• Billing a residential per-diem facility fee and then also billing individual therapy and group therapy revenue codes for the same day when the payer expects those services to be bundled, leading to CO-97 adjustments that look like denials but are really packaging edits.
• Omitting the facility fee entirely for tele-behavioral services provided out of a hospital outpatient department, because the team assumes only the professional claim is allowed, leaving money on the table where payers actually permit a facility component.
• Failing to align prior authorization to the facility level of care, for example, getting auth for psychotherapy CPT codes only, not for the PHP or residential program per diem, so the entire facility fee later denies as non-covered (CO-197 or CO-96) even though staff documented the care correctly.

In behavioral health, facility fees often take the form of per-diem or program fees for levels of care such as inpatient psychiatry, residential treatment, withdrawal management, PHP, and IOP. The single per-diem line on the UB-04 may represent therapy groups, nursing observation, milieu, and program overhead, while separate revenue codes handle room and board or ancillary services. Misaligning those program codes with what the payer expects is an easy way to lose whole days of revenue.

Many behavioral health benefits are carved out to a separate behavioral health vendor. That vendor may apply different rules for facility versus professional services, including requiring concurrent authorization for facility-based days but not for outpatient therapy. You can see a clean-looking claim still deny for all units past the auth span, because the facility per diem is tied directly to authorization dates and total days approved.

State Medicaid and Medicaid managed care plans often pay behavioral health facility services under very specific rate structures. Examples include fixed per-diem rates for residential and withdrawal management, or structured PHP and IOP codes that combine therapy and facility costs. These programs may carve out room and board, limit facility fees when the member is in another covered setting, or prohibit separate billing for services that commercial payers might allow. Getting the facility fee wrong in Medicaid can trigger not only denials but audit risk and recoupment.

For telehealth in behavioral health, some payers cover only the professional fee when services are provided from the clinician's home or a non-hospital clinic, while others allow a limited facility or "originating site" fee only when a licensed facility is the site of service. Billing a facility fee for a virtual group run from a standard office suite can quickly draw CO-96 or policy-based recoupments if it conflicts with payer telehealth policies.

For facility fees, AI agents can read contracts, fee schedules, and historical remittances to learn how each payer prices specific revenue codes, HCPCS, and levels of care. They can check every UB-04 for consistent use of revenue codes, place of service, and covered per-diem structures, then flag claims where the facility fee looks underpaid, bundled unexpectedly, or missing altogether. AI can also cross-check authorizations against billed program days to catch facility units that will deny later if you bill past the approved span.

Supabill's claims-scrubbing agent holds payer-specific rules about which settings can bill a facility fee, which revenue codes bundle with which per diems, and when a telehealth service can support a facility component. Its denials agent reads every 835, classifies CO-97, CO-45, and CO-96 patterns related to facility fees, and surfaces recurring issues by payer and program line so humans can fix workflows or renegotiate contracts. Human experts still need to interpret ambiguous behavioral health contracts, handle payer medical policy disputes, and make judgment calls on when to appeal a facility underpayment versus write off a small variance.

What is the difference between a facility fee and a professional fee?

A facility fee pays the hospital or treatment center for the costs of running the site of care, such as space, equipment, and nursing or program staff. A professional fee pays the clinician for the service itself, using CPT or HCPCS codes on a professional claim. Many encounters in hospital-based or residential programs legitimately generate both fees.

Can a freestanding behavioral health clinic bill a facility fee?

Usually not in the same way a hospital outpatient department can. Freestanding clinics typically bill only professional fees on the CMS-1500, unless they meet specific state or payer criteria as a licensed facility with an approved payment methodology. Always confirm with your payer contracts and any Medicaid or managed care manuals.

Why do patients sometimes get separate bills for a behavioral health visit?

In a hospital-based or provider-based clinic, one claim is for the clinician's professional services and another claim is for the facility fee. The patient may have separate copays or coinsurance for each. Clear scripting and estimates at registration help prevent surprise and complaints to payers or regulators.

Can facility fees be billed for telehealth behavioral health services?

Some payers allow a limited facility or originating-site fee for telehealth when the patient connects from a qualified facility, while others pay only the professional fee. Behavioral health programs should confirm payer rules for telehealth modifiers, allowed originating sites, and any restrictions on facility components before billing. Source

How do I know if a facility fee was paid correctly on a claim?

Compare the paid amount on the revenue-code lines and per-diem codes to the contracted rates or published fee schedule for that payer. Review the remittance advice for reductions marked CO-45, CO-96, or CO-97 that might indicate incorrect coding, bundling, or non-coverage of certain facility components, then follow up for corrections or appeals as needed.
