Dispute a medical bill in Illinois.

The law

Illinois Consumer Coverage Disclosure Act + Network Adequacy & Transparency Act

Cite: 215 ILCS 124, 215 ILCS 134

Illinois law combines network-adequacy rules (insurers must maintain enough in-network providers within reasonable distance) with surprise-billing protections that prohibit balance billing for in-network facility care provided by out-of-network providers.

Your rights

What Illinois protects you from.

  • 01

    Patients pay only in-network cost-sharing for emergency services and for ancillary services (anesthesia, pathology, radiology, lab) at in-network facilities.

  • 02

    Illinois Department of Insurance handles complaints and operates a hotline for surprise-billing disputes.

  • 03

    Network adequacy: if no in-network provider is within reasonable distance, services from an out-of-network provider must be billed at in-network rates.

  • 04

    You can file complaints with the Attorney General Health Care Bureau which has subpoena power over hospitals.
