Illinois Medical Malpractice Funding

Illinois medical malpractice claims must be filed within two years of the date the plaintiff knew, or through reasonable diligence should have known, of the injury, under 735 ILCS 5/13-212(a). A four-year statute of repose runs from the act or omission regardless of discovery. For a plaintiff under 18 at the time of the act, the repose period is eight years from the act or until the twenty-second birthday, whichever comes first, under section 13-212(b). Fraudulent concealment extends the period under 735 ILCS 5/13-215. Illinois has no presuit notice or screening panel, but the complaint must be accompanied by an attorney affidavit and a written report from a qualified health professional stating that there is a reasonable and meritorious cause for filing, under 735 ILCS 5/2-622; the court may allow 90 additional days where the attorney could not obtain the consultation before the deadline.

Modified comparative fault with a 51 percent bar under 735 ILCS 5/2-1116. A med-mal plaintiff whose contributory fault is more than 50 percent of the proximate cause of the injury is barred; at 50 percent or less the damages are reduced proportionally. Patient noncompliance defenses are tried under this framework, and Illinois juries are instructed on it in medical negligence cases.

Illinois has no enforceable cap on non-economic damages in medical malpractice. The $500,000 physician and $1,000,000 hospital caps enacted in 2005 in 735 ILCS 5/2-1706.5 were struck down in Lebron v. Gottlieb Memorial Hospital, 237 Ill.2d 217 (2010), where the Illinois Supreme Court held that a legislative cap violates the separation of powers clause by invading the judiciary's remittitur function. Because the 2005 act was non-severable, the entire package fell. Punitive damages are unavailable in Illinois healing-art malpractice actions under 735 ILCS 5/2-1115. Damages against state-operated facilities are heard in the Court of Claims and subject to its limits.

Illinois awards prejudgment interest in medical malpractice cases under 735 ILCS 5/2-1303(c), added by Public Act 102-6 effective July 1, 2021. Interest accrues at six percent per year from the date the action is filed on all damages except punitive damages, sanctions, attorney fees, and costs, for no more than five years. If the defendant made a written settlement offer within 12 months of filing and the judgment does not exceed it, no prejudgment interest is awarded; if the judgment exceeds the offer, interest runs only on the difference. The statute applies to actions for personal injury or wrongful death caused by negligence, which includes medical negligence.

Under 735 ILCS 5/2-101, a med-mal action is filed in the county of residence of any defendant joined in good faith or in the county where the transaction or some part of it occurred — for most claims, the county of the hospital or clinic. Hospital corporations reside in any county where they have an office or do business, which affects Cook County filings. Claims against the State and its university hospitals proceed in the Court of Claims.

Illinois regulates consumer litigation funding under the Consumer Legal Funding Act, 815 ILCS 121/1 et seq.. Fee capped at 18% of the funded amount per 6-month period, plus a one-time document preparation fee of no more than $75.

How does Illinois prejudgment interest change the funding equation?

Since July 2021, a med-mal judgment carries six percent annual interest from the filing date for up to five years. That partially compensates the plaintiff for the time the case takes and makes an early lowball defense offer more expensive to the carrier, which supports a plaintiff who can afford to wait.

The interest applies only if the case reaches judgment, and a written settlement offer within 12 months of filing can cut it off or limit it to the excess over the offer. Underwriting treats prejudgment interest as a factor in the defense's settlement calculus rather than as a component of expected recovery. The five-year ceiling also bounds its effect in the longest cases.

Why does Lebron matter for the value of an Illinois claim?

Lebron struck the 2005 non-economic caps and, by the separation of powers reasoning, made a future cap difficult to enact. Illinois med-mal damages are limited only by the evidence and remittitur, so catastrophic and birth injury claims are underwritten on their full documented loss.

The same act had bundled the caps with other reforms, and the court held the package non-severable, so all of it fell. Punitive damages remain unavailable in Illinois healing-art malpractice under section 2-1115, which is the one statutory limit that still applies. The liability analysis is unchanged: the section 2-622 report and later expert proof still decide the case.

What does the four-year repose mean for a late-discovered Illinois claim?

Section 13-212 gives two years from discovery, but the four-year repose from the act is absolute except for fraudulent concealment. A patient who learns of an error more than four years after treatment usually cannot sue, and funders confirm the act date against the filing date before advancing.

Minors are treated differently: the repose runs eight years from the act or until the twenty-second birthday, whichever is first, which keeps birth injury claims open longer. The section 2-622 report requirement can also interact with the deadline, since a 90-day extension to obtain the consultation is available only where the attorney could not secure it in time.
