Illinois medical bill laws

Surprise billing

For state-regulated insured plans, you pay no more than in-network cost-sharing for emergency care from out-of-network providers or facilities, and for ancillary care such as anesthesia or radiology from out-of-network providers at in-network facilities. Air ambulance and short-term plans are excluded. (215 ILCS 5/356z.3a)

State surprise billing laws reach plans the state regulates, such as most individual plans and fully insured employer plans. A self-funded employer plan follows the federal No Surprises Act, and a state law reaches it only if the plan opted in.

Ground ambulance

We found no Illinois law limiting ground ambulance balance billing, in the sources we checked, and the federal law does not cover ground ambulance. (215 ILCS 5/356z.3a(b-10))

Hospital financial assistance

Illinois hospitals must give uninsured Illinois residents free care at or below 200% of the poverty guidelines and a discount up to 600%, on charges over $150. Rural and critical access hospitals use 125% and 300%. (210 ILCS 89/10 (Hospital Uninsured Patient Discount Act))

• hospitals other than rural or critical access hospitals: free care at or below 200% of the guideline ($66,000 a year for a household of four); discounted care up to 600% ($198,000 for four).
• rural and critical access hospitals: free care at or below 125% of the guideline ($41,250 a year for a household of four); discounted care up to 300% ($99,000 for four).

Conditions in the law: Uninsured Illinois residents only; a high-deductible plan counts as insurance. You must apply (within 90 days of discharge, service, screening or a public-coverage denial). Applies to medically necessary charges over $150 per visit ($300 at rural and critical access hospitals). Total collected in 12 months is capped at 20% of family income.

Medical debt

• Credit reporting agencies may not include adverse information they know or should know relates to medical debt, or to a collection action on it, in a credit report, and may not keep medical debt information in a consumer's file. (815 ILCS 505/2EEEE)
• Hospitals may pursue collection against uninsured patients only after screening for coverage and financial assistance, applying required discounts, offering a reasonable payment plan and allowing 90 days to apply for aid; they may not sue uninsured patients shown to lack sufficient income and assets. (210 ILCS 88/30, 88/35)

In an October 2025 interpretive rule, the CFPB said it reads federal credit reporting law as generally preempting state laws on credit report contents; the rule also says courts decide such questions (CFPB interpretive rule, 90 FR 48710 (Oct. 28, 2025)).

Coming change, not yet in force: Starting January 1, 2027, a hospital suing a patient for unpaid medical debt may not file for or be granted a lien on the patient's primary residence, and a medical debt judgment may not become a lien on that home. (210 ILCS 88/30(c-5); 735 ILCS 5/12-101 (P.A. 104-0490))

Complaints about a state-regulated plan go to the Illinois Department of Insurance, Office of Consumer Health Insurance.

How the No Surprises Act limits surprise bills

The No Surprises Act covers people in job-based plans, individual plans and Marketplace plans. For emergency care, out-of-network air ambulance rides, and non-emergency care from an out-of-network clinician at an in-network hospital, hospital outpatient department, critical access hospital or ambulatory surgical center, you generally owe only your in-network cost-sharing. That payment counts toward your in-network deductible and out-of-pocket limit.

A provider can ask you to waive this protection for some scheduled care, but only with written notice at least 72 hours ahead (on the day you book, if you book less than 72 hours ahead, and at least 3 hours before care the same day). Some services can never be waived, including emergency medicine, anesthesiology, pathology, radiology, neonatology, assistant surgeons, hospitalists, intensivists and diagnostic services, and neither can care for unforeseen, urgent needs that come up during the visit.

Two gaps matter most. Ground ambulance rides are not covered by the federal law, and Medicare, Medicaid, VA, TRICARE and Indian Health Service coverage use their own billing protections instead. If a bill looks wrong, call the No Surprises Help Desk at 1-800-985-3059 or file a complaint with CMS.

Uninsured or self-pay: the good faith estimate dispute

If you have no insurance, or have private insurance and choose not to bill it, providers must give you a written good faith estimate when you schedule care at least 3 business days ahead, and whenever you ask. Short-term plans, health care sharing ministries, farm bureau plans and self-funded student plans count as uninsured for this rule. CMS says people in Medicare, Medicaid and other federal programs do not get a good faith estimate, even for a service their program does not cover. CMS is also not enforcing the rule that the main provider's estimate list other providers, so ask each provider you expect a bill from, such as the anesthesiologist or the lab, for its own estimate.

When a provider's bill comes in at least $400 above that provider's estimate, you can start the federal patient-provider dispute process within 120 days of receiving the initial bill. The fee is $25. While the dispute is open, the provider may not send the bill to collections and must pause late fees, and it should stop collection that has already started. The threshold is per provider, so compare each provider's bill with its own line on the estimate.

Hospital financial assistance (charity care)

Every nonprofit hospital must have a written financial assistance policy covering emergency and medically necessary care. It must publish the policy and an application, cap what it charges people eligible under the policy at the amounts it generally bills insured patients, wait at least 120 days after the first bill before actions like credit reporting or a lawsuit, and accept applications for at least 240 days after the first bill.

Some states go further and set income levels at which hospitals must give free or discounted care. Those levels are stated as a percentage of the federal poverty guidelines. For 2026, 100% of the guideline is $15,960 for one person and $33,000 for a household of four in the 48 contiguous states and DC (Alaska and Hawaii are higher). The hospital applies its own policy and decides each application.

Medical debt and credit reports

A federal rule that would have removed medical debt from credit reports was vacated by a federal court on July 11, 2025, so no general federal ban is in force. Federal law does keep one kind off reports: a veteran's medical debt for VA-authorized care from an outside provider, for a year after the care and once it is paid or settled (15 U.S.C. 1681c(a)(7)-(8); 1681a). The three national credit bureaus say they leave off paid medical collections and medical collections under $500, and wait 1 year before an unpaid one appears. Several states ban or limit medical debt reporting by law; the table below shows which. In an October 2025 interpretive rule the CFPB said it reads federal credit reporting law as generally preempting state laws on credit report contents, and that courts decide such questions (CFPB interpretive rule, 90 FR 48710 (Oct. 28, 2025)). In August 2026 a federal court in Texas held that federal law preempts a Texas law keeping certain out-of-network medical debt off credit reports, and barred Texas from enforcing it (Consumer Data Industry Ass'n v. State of Texas, No. 1:19-cv-876-RP (W.D. Tex. Aug. 10, 2026)).

Separately, federal debt collection law bars a collector from collecting any amount the law does not permit, which can include an amount the No Surprises Act does not allow (15 U.S.C. 1692f(1)).

For a nonprofit hospital, reporting a debt to a credit bureau counts as an extraordinary collection action, so the federal waiting period and the pause while you apply for financial assistance both apply to it.
