Any cost-sharing requirements shall be applied as though the emergency ground ambulance services or urgent ground ambulance services had been received from a participating ground ambulance service provider. Except as otherwise provided in State or federal law, cost sharing shall be calculated based on the lesser of the policy's copayment or coinsurance for an emergency room visit or 10% of the recognized amount.

By accepting the payment from the health insurance issuer, the nonparticipating ground ambulance service provider shall not seek any payment from the beneficiary, insured, or enrollee for any amount that exceeds the deductible, coinsurance, or copay for services provided to the beneficiary, insured, or enrollee.

(b-15) Beginning on October 1, 2026, and each October 1 thereafter, each nonparticipating ground ambulance service provider shall file annually with the Department of Public Health, in the form and manner prescribed by the Department of Public Health, its average gross charge rates and any other information required by the Department of Public Health, by rule, for each of the following ground ambulance charge descriptions, as applicable: (1) basic life support, urgent base; (2) basic life support, emergency base; (3) advanced life support, urgent, level 1 base; (4) advanced life support, emergency, level 1 base; (5) advanced life support, emergency, level 2 base; (6) specialty care transport base; (7) emergency response, evaluation without transport base; (8) emergency response, treatment without transport base; (9) emergency response, paramedic intercept base; and (10) loaded mileage, per loaded mile charge for each of the applicable base charge descriptions services.

The Department of Public Health may also request information from nationally recognized organizations that provide data on health care costs. The Department of Insurance shall direct the health insurance issuer to the location in which the information reported to the Department of Public Health is stored.

Upon receipt of the provider's bill or facility's bill, the health insurance issuer shall provide the nonparticipating provider, nonparticipating ground ambulance service provider, or the facility with a written explanation of benefits that specifies the proposed reimbursement and the applicable deductible, copayment, or coinsurance amounts owed by the insured, beneficiary, or enrollee. The health insurance issuer shall pay any reimbursement subject to this Section directly to the nonparticipating provider, nonparticipating ground ambulance service provider, or the facility.

(d) For bills assigned under subsection (c), the nonparticipating provider or the facility may bill the health insurance issuer for the services rendered, and the health insurance issuer may pay the billed amount or attempt to negotiate reimbursement with the nonparticipating provider or the facility. Within 30 calendar days after the provider or facility transmits the bill to the health insurance issuer, the issuer shall send an initial payment or notice of denial of payment with the written explanation of benefits to the provider or facility. If attempts to negotiate reimbursement for services provided by a nonparticipating provider do not result in a resolution of the payment dispute within 30 days after receipt of written explanation of benefits by the health insurance issuer, then the health insurance issuer or nonparticipating provider or the facility may initiate binding arbitration to determine payment for services provided on a per-bill or batched-bill basis, in accordance with Section 300gg-111 of the Public Health Service Act and the regulations promulgated thereunder. The party requesting arbitration shall notify the other party arbitration has been initiated and state its final offer before arbitration. In response to this notice, the nonrequesting party shall inform the requesting party of its final offer before the arbitration occurs. Arbitration shall be initiated by filing a request with the Department of Insurance.

(e) The Department of Insurance shall publish a list of approved arbitrators or entities that shall provide binding arbitration. These arbitrators shall be American Arbitration Association or American Health Lawyers Association trained arbitrators. Both parties must agree on an arbitrator from the Department of Insurance's or its approved entity's list of arbitrators. If no agreement can be reached, then a list of 5 arbitrators shall be provided by the Department of Insurance or the approved entity. From the list of 5 arbitrators, the health insurance issuer can veto 2 arbitrators and the provider or facility can veto 2 arbitrators. The remaining arbitrator shall be the chosen arbitrator. This arbitration shall consist of a review of the written submissions by both parties. The arbitrator shall not establish a rebuttable presumption that the qualifying payment amount should be the total amount owed to the provider or facility by the combination of the issuer and the insured, beneficiary, or enrollee. Binding arbitration shall provide for a written decision within 45 days after the request is filed with the Department of Insurance. Both parties shall be bound by the arbitrator's decision. The arbitrator's expenses and fees, together with other expenses, not including attorney's fees, incurred in the conduct of the arbitration, shall be paid as provided in the decision.

(f) (Blank).

(g) Section 368a of this Code Act shall not apply during the pendency of a decision under subsection (d). Upon the issuance of the arbitrator's decision, Section 368a applies with respect to the amount, if any, by which the arbitrator's determination exceeds the issuer's initial payment under subsection (c), or the entire amount of the arbitrator's determination if initial payment was denied. Any interest required to be paid to a provider under Section 368a shall not accrue until after 30 days of an arbitrator's decision as provided in subsection (d), but in no circumstances longer than 150 days from the date the nonparticipating facility-based provider billed for services rendered.

(h) Nothing in this Section shall be interpreted to change the prudent layperson provisions with respect to emergency services under the Managed Care Reform and Patient Rights Act.

(i) Nothing in this Section shall preclude a health care provider from billing a beneficiary, insured, or enrollee for reasonable administrative fees, such as service fees for checks returned for nonsufficient funds and missed appointments.

(j) Nothing in this Section shall preclude a beneficiary, insured, or enrollee from assigning benefits to a nonparticipating provider when the notice and consent criteria are satisfied under paragraph (2) of subsection (b-5) or in any other situation not described in subsection (b) or (b-5).

(k) Except when the notice and consent criteria are satisfied under paragraph (2) of subsection (b-5), if an individual receives health care services under the situations described in subsection (b) or (b-5), no referral requirement or any other provision contained in the policy or certificate of coverage shall deny coverage, reduce benefits, or otherwise defeat the requirements of this Section for services that would have been covered with a participating provider. However, this subsection shall not be construed to preclude a provider contract with a health insurance issuer, or with an administrator or similar entity acting on the issuer's behalf, from imposing requirements on the participating provider, participating emergency facility, or participating health care facility relating to the referral of covered individuals to nonparticipating providers.

(l) Except if the notice and consent criteria are satisfied under paragraph (2) of subsection (b-5), cost-sharing amounts calculated in conformity with this Section shall count toward any deductible or out-of-pocket maximum applicable to in-network coverage.

(m) The Department has the authority to enforce the requirements of this Section in the situations described in subsections (b) and (b-5), and in any other situation for which 42 U.S.C. Chapter 6A, Subchapter XXV, Parts D or E and regulations promulgated thereunder would prohibit an individual from being billed or liable for emergency services furnished by a nonparticipating provider or nonparticipating emergency facility or for non-emergency health care services furnished by a nonparticipating provider at a participating health care facility.

(n) This Section does not apply with respect to air ambulance services. This Section does not apply to any policy of excepted benefits or to short-term, limited-duration health insurance coverage.

(o) A home rule unit may not regulate payments for ground ambulance service in a manner inconsistent with this Section. This subsection is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State.

(p) (o) Notwithstanding any other provision of law to the contrary, if a beneficiary, insured, or enrollee receives neonatal intensive care from a nonparticipating provider or nonparticipating facility, a health insurance issuer shall ensure that the beneficiary, insured, or enrollee shall incur no greater out-of-pocket costs than he or she would have incurred with a participating provider or a participating facility, as long as the nonparticipating provider or nonparticipating facility bills the neonatal intensive care as emergency services.
