Medical Bill Collection Laws in Illinois: Your Rights and Options

Medical bill collection laws in Illinois give you more room than most people realize. Hospitals have to offer financial assistance and a payment plan before turning your bill over to collections, licensed collectors must send written validation and stop calling if you dispute the debt, wage garnishment is capped at 15% of your gross weekly pay, and you have five years to be sued before the debt becomes time-barred. Knowing where these protections sit — and acting on them within their deadlines — is what separates a manageable bill from a default judgment and a garnished paycheck.

What Hospitals Must Do Before Sending Your Bill to Collections

An Illinois hospital cannot hand your unpaid bill to a collection agency the moment you fall behind. The Fair Patient Billing Act and the Hospital Uninsured Patient Discount Act require a sequence of steps first, and skipping them gives you a defense later.

If you are uninsured, the hospital must give you at least 90 days from your discharge or outpatient visit to apply for financial assistance before it can start collection action.¹ During that window the hospital must screen you for discount programs, let you verify that the bill is accurate, and offer a reasonable payment plan if you cannot pay in full. Charity care information has to be offered regardless of your immigration status or residency.

If you are insured, the hospital must give you 90 days from the initial bill to request a reasonable payment plan.¹ If you ask for one but cannot agree on terms within 90 days, the hospital can then move to collections. This is where a lot of people lose ground: they set the bill aside, the 90 days pass in silence, and the next letter is from a collection agency.

Every bill sent to an uninsured patient must include a prominent statement that you may qualify for an income-based discount and explain how to apply.² Hospitals must also post signage in admission and registration areas — in English and in any language spoken by at least 5% of their patients — telling you financial assistance may be available.³ You can also request a fully itemized statement at any time.

Nonprofit hospitals carry an additional federal obligation. Before taking any “extraordinary collection action” — selling your debt, reporting it to credit bureaus, placing a lien, garnishing wages, suing you, or denying future medically necessary care — a 501(c)(3) hospital must wait at least 120 days from the first post-discharge billing statement and notify you about its Financial Assistance Policy.4 If you never received that notice from a nonprofit hospital, raise it.

Rules Collectors Must Follow Once They Have Your Account

Every collection agency operating in Illinois has to hold a state license. The Illinois Collection Agency Act makes it illegal to collect debts, solicit accounts, or even maintain a sales office in the state without one, and the Department of Financial and Professional Regulation can fine an agency up to $10,000 per violation and revoke its license.⁵

Within five days of first contacting you, a collector must send a written notice showing the amount owed, the name of the creditor, and a statement that you have 30 days to dispute the debt in writing.⁵ If you dispute the debt within that 30-day window, the collector has to stop collection activity until it sends you verification. Use the window. A written dispute is often the fastest way to surface billing errors, wrong amounts, or debt that was never yours.

Federal law layers on more limits. Under the Fair Debt Collection Practices Act, collectors cannot call before 8 a.m. or after 9 p.m. local time and must stop contacting you at work if you tell them your employer prohibits personal calls.⁶ Threats, abusive language, and repeated harassing calls are prohibited under both the FDCPA and the Illinois Collection Agency Act. A collector who violates the FDCPA can be sued within one year for your actual damages plus up to $1,000 in additional statutory damages, along with attorney’s fees and court costs.⁷

Surprise Bills That Shouldn’t Exist at All

Some medical bills you receive were never legally owed. The federal No Surprises Act, in effect since January 2022, prohibits out-of-network providers from billing you directly for the difference between their charge and what your insurance pays in most emergency situations, and your plan cannot deny coverage because you went to an out-of-network emergency room without prior authorization.⁸

The Act also reaches non-emergency care. If you go to an in-network facility, ancillary providers like anesthesiologists, radiologists, and pathologists cannot surprise-bill you for out-of-network charges, and you cannot be asked to waive these protections for ancillary services or for emergency care before you are stabilized.⁸

If you are uninsured or paying out of pocket, providers must give you a good faith estimate of expected charges when you schedule a service or when you ask for one.⁹ The estimate has to itemize the expected costs, including charges from other providers reasonably expected to be involved in your care. A final bill that comes in substantially higher gives you grounds to dispute.

Medical Debt on Your Credit Report

The credit reporting picture has changed, but not as much as some coverage suggested. Since 2022 and 2023, Equifax, Experian, and TransUnion have voluntarily agreed that paid medical collections no longer appear on credit reports, unpaid medical collections do not appear until they are at least one year old, and medical collections under $500 are excluded entirely.¹⁰ These are policies, not laws.

A broader CFPB rule finalized in 2024 would have banned medical debt from credit reports altogether. A federal court in Texas vacated that rule on July 11, 2025, holding that the CFPB had exceeded its authority under the Fair Credit Reporting Act.¹¹ So medical debt above $500 that goes unpaid for more than a year can still land on your report under the current bureau policies. The one-year buffer is real breathing room to apply for financial assistance, negotiate, or dispute errors. Paying the debt at any point should get it removed. Keep written records of every payment and every call.

How Long a Collector Has to Sue You

In Illinois, a creditor or collector has five years to file a lawsuit to collect medical debt. Once that window closes, an expired statute of limitations is a complete defense — if you raise it.

Two traps. Making even a small partial payment on old medical debt can restart the five-year clock in some situations. And collectors sometimes sue on time-barred debt hoping you will not show up to raise the defense. If you ignore the lawsuit and a default judgment is entered, the court does not check the statute of limitations on its own. You lose the protection by not asserting it.

The statute only blocks a lawsuit. It does not erase the debt or stop a collector from contacting you about it, and unpaid medical debt can stay on your credit report for up to seven years from the original delinquency under the bureau policies regardless of whether the statute of limitations has run.

If You Are Sued for a Medical Bill

Getting served with a lawsuit over a medical bill is alarming. The worst thing you can do is ignore it. Without a written response, the collector gets a default judgment — essentially the court accepting their version of the facts — and can then move to garnish your wages, freeze your bank accounts, and place liens on your property.

You typically have 30 days after being served to file an answer, though the exact deadline depends on how you were served. Defenses to raise can include an expired statute of limitations, lack of proper debt verification, incorrect amounts, and the hospital’s failure to follow the billing and financial assistance rules above. If you cannot afford a lawyer, contact the Illinois Attorney General’s Health Care Bureau or a local legal aid organization.

If judgment is entered against you on a consumer debt of $25,000 or less, interest accrues at 5% per year instead of the standard 9% that applies to most other judgments. Above $25,000, the 9% rate applies.¹² You can stop interest from accruing by tendering full payment of the judgment, costs, and accrued interest, even while an appeal is pending.

What They Can Take if They Win

Illinois protects wages more aggressively than federal law does. Federal law allows a creditor to garnish up to 25% of disposable earnings. Illinois limits garnishment to the lesser of 15% of your gross weekly pay or the amount by which your disposable earnings exceed 45 times the applicable minimum wage.¹³ For someone earning close to minimum wage, that formula can protect the entire paycheck.

Illinois also shields specific personal property from judgment creditors under 735 ILCS 5/12-1001:¹⁴

Household goods including furniture, appliances, clothing, computers, phones, and medications, though a creditor can seek court permission to levy on a single item worth more than $5,000 at resale.
Up to $4,000 in equity in any property not covered by another exemption (the wildcard exemption).
Up to $3,600 in equity in one motor vehicle.
Up to $2,250 in professional tools, books, or implements of your trade.
Social Security, unemployment compensation, veterans’ benefits, disability payments, and alimony or child support, fully exempt to the extent reasonably necessary for your support.

These exemptions do not apply themselves. You have to claim them affirmatively after judgment is entered.

When a Collector or Hospital Breaks the Rules

Under the Illinois Collection Agency Act, the Department of Financial and Professional Regulation can fine a collection agency up to $10,000 per violation, suspend or revoke its license, or place it on probation.⁵ Under the FDCPA, private lawsuits recover actual damages plus up to $1,000 in statutory damages per case, or in a class action the lesser of $500,000 or 1% of the collector’s net worth, plus attorney’s fees.⁷

For hospitals, the Attorney General can seek civil penalties of up to $500 per violation when a hospital knowingly and repeatedly fails to provide required discount information under the Hospital Uninsured Patient Discount Act, and can refer a hospital found to have violated the Act to the Illinois Department of Public Health for potential adverse licensure action.² Nonprofit hospitals that fail to meet federal 501(r) financial assistance and billing requirements risk losing tax-exempt status.

Where to File a Complaint

The Illinois Attorney General’s Health Care Bureau handles complaints about hospital billing disputes, unfair collection practices, and violations of the state’s hospital billing and financial assistance laws.¹⁵ You can file online, by phone through the Bureau’s toll-free hotline, or by mail. The Bureau mediates between consumers and providers and can escalate to formal investigation when it sees a pattern.

For collection agency misconduct specifically, you can also file with the Illinois Department of Financial and Professional Regulation, which oversees licensing. Filing in both places at once is common and increases the chance someone acts on your complaint.

Options When the Debt Is Unmanageable

The Illinois Medical Debt Relief Act, in effect from July 1, 2024 through July 1, 2029, directs the state to purchase and cancel medical debt for low-income residents.¹⁶ You do not apply individually. Debt is bought in bulk based on income and geographic criteria, and you would receive notification if yours was selected for erasure.

Federal bankruptcy remains available. Medical bills are unsecured debt, among the easiest obligations to discharge. Chapter 7 can eliminate medical debt in roughly three to four months, but you must first pass a means test comparing your income to the Illinois state median. If your income is too high for Chapter 7, Chapter 13 lets you propose a three-to-five-year repayment plan, at the end of which remaining eligible medical debt is discharged. Bankruptcy carries serious credit consequences and should not be the first option, but for someone facing tens of thousands in medical debt with no realistic path to repayment, it can be the difference between years of garnishment and a genuine fresh start. Talk to a bankruptcy attorney before filing; the means-test and exemption calculations are easy to get wrong on your own.
