Key Takeaways
- Forty percent is the hard ceiling. Under the Illinois Health Care Services Lien Act, all health care liens combined cannot exceed 40% of the verdict, judgment, award, settlement or compromise, no matter how large the medical bills are.
- No single category takes more than a third. One licensed category, meaning all the hospitals together or all the physicians together, may never receive more than one-third of the recovery.
- The 40% splits twenty and twenty. Once the liens reach the ceiling, health care professionals are limited to 20% and health care providers to 20%, and whatever one side does not use is reallocated to the other inside the same 40%.
- Attorney fees get capped too. When health care liens meet or exceed 40%, all attorney liens are limited to 30% of the recovery, which is less than the one-third most contingency agreements call for.
- A cap is not a discharge. The statute limits what a provider can take out of the settlement, not what it is owed. The unpaid balance survives, and the provider may still pursue it by other means.
The case settles. The number sounds like enough. Then the arithmetic starts, and a letter arrives from the hospital that treated you the night of the crash, claiming a piece of the money before you see any of it.
Injured people in Illinois usually learn about medical liens at exactly the wrong moment, after the settlement is agreed and the leverage is gone. The good news is that Illinois does not let the bills run the table. A single statute puts a hard ceiling on what every provider can pull out of your recovery, and it puts a second ceiling on your own lawyer.

What a Medical Lien Is in Illinois
A medical lien is a legal claim a health care professional or provider places on the money you recover from the person who hurt you. It does not attach to your house, your wages or your bank account. It attaches to the claim itself, and it is paid out of the settlement or judgment before the balance reaches you.
The controlling law is the Health Care Services Lien Act, 770 ILCS 23. Section 10(a) gives every health care professional and provider who treats an injured person a lien on all claims and causes of action of that person, for the amount of its reasonable charges up to the date damages are paid. Our overview of medical liens covers the basic definition; this guide is about the ceilings and the arithmetic.
Two limits are built into that same sentence. The lien covers reasonable charges, not whatever appears on the bill, and the total of all such liens cannot exceed 40% of the recovery.
Who can actually file one
Not every party sending you a bill has a lien under this Act. Section 5 defines two closed lists, and the distinction matters later, because each list gets its own sub-cap.
| Category | Who is included |
|---|---|
| Health care professional | Licensed physician, licensed dentist, licensed optometrist, licensed naprapath, licensed clinical psychologist, or licensed physical therapist |
| Health care provider | Licensed hospital, licensed home health agency, licensed ambulatory surgical treatment center, an accredited ambulatory surgical treatment facility, licensed long-term care facility, or licensed emergency medical services personnel |
One exclusion is written into Section 10(a) directly: services rendered under the Workers’ Compensation Act or the Workers’ Occupational Diseases Act are outside this statute. If your treatment was billed through a work injury claim, a different set of rules governs the money, and our Illinois workers’ compensation page is the better starting point.
The 40 Percent Ceiling
Section 10(a) states the limit plainly. The total amount of all liens under the Act shall not exceed 40% of the verdict, judgment, award, settlement or compromise secured by or on behalf of the injured person.
That is a ceiling on the aggregate, not on each bill. Ten providers with liens do not get 40% each. They share the same 40%, in proportion to their charges, under Section 10(c).
How the 40 percent is divided
Section 10(c) does three things at once, and they interact.
- Proportionate sharing. All lienholders share proportionate amounts within the 40% limit. A provider owed half the total charges gets half of whatever is available.
- The one-third limit on any one category. No individual licensed category of professional, such as physicians, or of provider, such as hospitals, may receive more than one-third of the recovery. This applies whether or not the liens reach 40%.
- The twenty and twenty split. If the total of all liens meets or exceeds 40%, then all professional liens are capped at 20% and all provider liens are capped at 20%, with one important qualifier below.
The qualifier is the part most summaries leave out. The statute directs that liens be satisfied to the fullest extent possible by reallocating the amount unused within the aggregate 40%. If the physicians only claim 12%, the remaining 8% does not vanish. It moves to the hospital side, subject always to the one-third limit on any single category.
A worked example on a $100,000 settlement
Assume a hospital bills $52,000, a physician group bills $18,000, and the fee agreement with your lawyer is the customary one-third.
| Claim on the settlement | Billed or contracted | Statutory ceiling | Paid |
|---|---|---|---|
| Hospital (provider) | $52,000 | $20,000 base | $22,000 |
| Physician group (professional) | $18,000 | $20,000 | $18,000 |
| All health care liens | $70,000 | $40,000 | $40,000 |
| Attorney lien | $33,333 | $30,000 | $30,000 |
| Left for the injured person | $30,000 |
Without the Act, $70,000 of bills against a $100,000 settlement plus a one-third fee would leave the injured person with nothing. The statute is what turns that into $30,000.
What a Provider Must Do to Have a Lien at All
A lien is not automatic. Section 10(b) requires a written notice, and it is specific about both content and delivery. The notice must contain:
- The name and address of the injured person
- The date of the injury
- The name and address of the health care professional or provider
- The name of the party alleged to be liable to compensate the injured person
That notice has to be served on both the injured person and the party against whom the claim exists, by registered mail, certified mail or in person. Serving one and not the other does not complete it.
Timing carries real consequences. The statute provides that a payment made in good faith to anyone other than the lienholder, before the lien notice is served, bars or prevents the creation of an enforceable lien to the extent of that payment. A provider that sits on its notice can lose the lien entirely.
The 20-day rule that voids a lien
Section 25 is the provision injured people almost never hear about. After a written request signed by the patient or the patient’s representative, or a subpoena, a provider claiming a lien has 20 days to furnish three written statements: the nature and extent of the injuries, the nature and extent of the treatment given, and the history of how the injuries occurred as recorded in the records.
If the provider fails or refuses to supply that statement after a proper request, Section 25(b) says the lien “shall immediately become null and void.” Not reduced. Void.
What You Have to Do
The obligations run both directions, and missing one creates problems at the worst time.
- Give notice before the money moves. Section 15 provides that a judgment, award, settlement or compromise may not be satisfied without the injured person first giving written notice to any provider that served a lien notice.
- Use the court if the numbers do not work. Section 30 lets either the injured person or the provider petition the circuit court, on written notice to all interested adverse parties, to adjudicate the rights of everyone involved and enforce the liens. This is the mechanism for a disputed or inflated lien.
Section 20 adds a detail that matters in larger cases. If the recovery is paid over time through an annuity or another extended payment mechanism, the lien must be satisfied by the paying party to the fullest extent Section 10 permits before the annuity is established. Providers do not wait in line behind a structured settlement. This comes up often in catastrophic injury cases, where structured payouts are common.
Liens Are Not the Same as Subrogation
Health insurers, Medicaid plans and similar payers often assert a right of reimbursement out of your settlement. That is subrogation, and Illinois treats it differently.
Section 50 provides that when a subrogation or reimbursement claim exists and your recovery is reduced by comparative fault, or by the uncollectibility of the full value of the claim because of limited liability insurance, the subrogation claim is reduced in the same proportion. After that reduction, the party asserting it must bear a pro rata share of your attorney’s fees and litigation expenses.
Then comes the exception that surprises people. Section 50 expressly does not apply to lienholders under the Health Care Services Lien Act, nor to workers’ compensation liens, nor to claims recouping uninsured or underinsured motorist payments under Sections 143a and 143a-2 of the Illinois Insurance Code. A hospital holding a health care services lien does not pay a share of your legal fees. Its protection is the 40% ceiling instead.
A Cap Is Not Forgiveness
This is the expectation that needs setting early. Section 45 states that nothing in the Act limits the right of a provider, or an attorney, to pursue collection of its reasonable charges through all available means, and that a lienholder may seek payment of the charges that remain unpaid after its lien is satisfied.
In the example above, the hospital billed $52,000 and collected $22,000 from the settlement. The remaining $30,000 does not disappear because the lien was capped. It remains a debt, and it can be pursued like any other.
That is precisely why the negotiation matters more than the arithmetic. The statutory limits under Section 10(c) may be waived or reduced by the lienholder, and providers routinely accept less than the ceiling to close a file. Whether that happens depends on who is asking and what leverage exists. If you are working through who pays your medical bills after a crash, or trying to recover lost wages, the lien negotiation is usually where the real money is won or lost.
Frequently Asked Questions
Can a hospital put a lien on my personal injury settlement in Illinois?
Yes. Under 770 ILCS 23/10(a), a licensed hospital that treated you has a lien on your claim for its reasonable charges. It must serve a written lien notice on you and on the party alleged to be liable, by registered mail, certified mail or in person, before the lien is enforceable.
How much can a hospital take from my settlement in Illinois?
All health care liens combined are capped at 40% of the recovery. No single licensed category, including all hospitals together, may take more than one-third. If total liens reach 40%, hospitals and other providers are limited to 20%, which can rise through reallocation if professionals do not use their full 20%.
How do I know if I have a medical lien?
You should have received a written lien notice containing your name and address, the date of injury, the provider’s name and address, and the name of the party alleged to be liable. If no notice was served on both you and the liable party before payment was made in good faith, an enforceable lien may never have been created.
Do medical liens apply to workers’ compensation cases?
No. Section 10(a) excludes services rendered under the Workers’ Compensation Act and the Workers’ Occupational Diseases Act from the Health Care Services Lien Act.
What happens if the provider ignores a request for records?
Section 25 gives a lien-claiming provider 20 days to furnish written statements about your injuries, treatment and history after a signed medical authorization request or subpoena. If it fails or refuses, the lien immediately becomes null and void.
Does the hospital help pay my attorney’s fees?
No. Section 50 requires subrogation and reimbursement claimants to bear a pro rata share of attorney’s fees, but it expressly excludes lienholders under this Act. A hospital lien is limited by the 40% ceiling instead.
Can I still owe the hospital after the lien is paid?
Yes. Section 45 preserves the provider’s right to collect the balance of its reasonable charges by other means after the lien is satisfied. The cap limits what comes out of the settlement, not what you owe.
Can a medical lien be reduced?
Yes. Section 10(c) allows the statutory limits to be waived or reduced by the lienholder, and Section 30 lets either side petition the circuit court to adjudicate the rights of all interested parties and enforce the liens.
