Michigan medical bill laws

Surprise billing

For plans regulated by Michigan and state or local government employee plans, an out-of-network provider may not collect more than your in-network cost sharing for emergency care, or for non-emergency care at an in-network facility when you had no chance to choose an in-network provider. (MCL 333.24507)

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 Michigan law limiting ground ambulance balance billing, in the sources we checked, and the federal law does not cover ground ambulance. (DIFS publication FIS-PUB 8540)

Hospital financial assistance

Hospitals in Michigan's Medicaid program must accept 115% of Medicare rates as payment in full from uninsured patients with income up to 250% of the federal poverty guidelines. This is a price cap, not free care. (MCL 400.105d(2))

  • Medicaid-participating hospitals, uninsured patients only (price capped at 115% of Medicare): discounted care up to 250% ($82,500 for four).

Conditions in the law: Uninsured patients only. This is a price cap, not free care: a hospital in Michigan Medicaid must accept no more than 115% of Medicare rates as payment in full from an uninsured patient with income up to 250% of the poverty guidelines.

Medical debt

We found no Michigan law aimed specifically at medical debt collection or credit reporting, in the sources we checked. General debt collection law still applies.

Complaints about a state-regulated plan go to the Michigan Department of Insurance and Financial Services (DIFS).

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.

What this tool does not do

  • It does not decide whether a bill is wrong, whether you owe it, or whether a program will accept you. The plan, provider, hospital or dispute entity decides.
  • It does not read your explanation of benefits or bill. Network status, waivers and amounts are what you tell it.
  • It covers federal law and the state laws we could confirm at official sources on October 20, 2026. A state with no law listed may still have regulations, local rules or hospital policies that help.
  • It is not legal advice. For a large bill or a lawsuit, a legal aid office or a lawyer can review the papers.
  • Nothing you type is sent or stored, and the letter is built in your browser.

Frequently Asked Questions

Does Michigan have a surprise medical billing law?

(MCL 333.24507). The federal No Surprises Act also applies. 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.

Are ground ambulance surprise bills limited in Michigan?

We found no Michigan law limiting ground ambulance balance billing in the sources we checked, and the federal No Surprises Act does not cover ground ambulance.

Do Michigan hospitals have to offer free or discounted care?

What is the No Surprises Act?

A federal law that limits surprise out-of-network bills for people in job-based, individual and Marketplace plans.

Questions go to the No Surprises Help Desk at 1-800-985-3059.

Does the No Surprises Act cover ground ambulance bills?

No. Ground ambulance rides are outside the federal law. Some states limit ground ambulance balance billing by their own law; the state table on this page shows which.

How do I dispute a bill that is higher than my good faith estimate?

If you were uninsured or self-pay and a provider billed at least $400 more than its estimate, you can start the federal patient-provider dispute process within 120 days of receiving the initial bill. The fee is $25, and the provider may not send the bill to collections while the dispute is open.
