Illinois Medical Malpractice — No Caps
Illinois has NO damage caps as of 2010. The Illinois Supreme Court struck down the 2005 legislative caps ($500K against physicians, $1M against hospitals) in Lebron v. Gottlieb Memorial Hospital, finding they violated the separation of powers doctrine of the Illinois Constitution. The legislature eventually repealed the cap statutes. Illinois remains a no-cap state and is one of the more plaintiff-favorable jurisdictions in the US.
SOL (735 ILCS 5/13-212): 2 years from the date the claimant knew or should have known of the injury/death. Statute of repose: 4 years from the date of the negligent act (absolute bar subject to fraud/concealment exception extending to 5 years from discovery under §5/13-215). Minors: 8 years from the negligent act, but cannot be filed after the child's 22nd birthday.
Expert affidavit required AT FILING (735 ILCS 5/2-622): certificate of counsel + written report from a qualified health professional finding 'reasonable and meritorious cause' for the lawsuit. Expert must be actively practicing or teaching in relevant specialty (or have done so within 6 years). Failure = MANDATORY DISMISSAL. Cook County (Chicago) juries produce dramatically higher verdicts than downstate Illinois — 3-5× difference for same injuries. Geographic venue choice is critical.
Key IL Med-Mal Statutes
IL med-mal uses strict pre-filing expert requirement + no-cap framework:
735 ILCS 5/13-212
SOLStandard: 2 years from knowledge of injury, 4-year statute of repose
Scope: Minors: 8 years from negligent act OR by 22nd birthday. Concealment extends 5 years from discovery (§5/13-215).
Lebron v. Gottlieb Memorial Hospital (2010)
Damage Caps STRUCK DOWNStandard: NO cap on non-economic damages
Scope: IL Supreme Court: 2005 caps ($500K physicians / $1M hospitals) violated separation of powers. Inseverability clause voided all of PA 94-677.
735 ILCS 5/2-622
Expert Affidavit at FilingStandard: Certificate of counsel + health professional report at complaint filing
Scope: Report must state 'reasonable and meritorious cause'. Failure = MANDATORY DISMISSAL.
No Statutory Punitive Cap
Uncapped PunitivesStandard: No punitive damages cap (though rare in med-mal)
Scope: Willful/wanton misconduct standard
Recovery Structure
Economic damages: medical, lost wages, future care — no cap. Non-economic damages: NO cap (Lebron 2010). Punitive damages: available for willful/wanton — no statutory cap, court discretion. Comparative fault: modified 51% bar under 735 ILCS 5/2-1116. Collateral source modified: court may reduce awards by collateral source payments, offset by premiums. Periodic payments: NOT mandatory — lump sum is default. Attorney fees: standard contingency.
§5/2-622 Expert Affidavit + Venue Strategy
§5/2-622 Expert Affidavit AT FILING: complaint must be accompanied by (1) certificate of counsel stating consultation with qualified health professional, (2) written report from that professional finding 'reasonable and meritorious cause'. Failure = MANDATORY DISMISSAL (can be amended within limited time). Expert must be practicing or teaching in relevant specialty within last 6 years. Stricter than CA (no affidavit) + NY (no affidavit); similar to TX §74.351 (post-filing 120 days) + FL §766.106 (pre-NOI). Cook County vs downstate: 3-5× verdict differential for same injuries. Plaintiff attorneys strongly prefer Cook County venue — fact-specific. Concealment exception: extends SOL to 5 years from discovery (§5/13-215) when active concealment proven.
Damage Caps (None, Post-Lebron)
NO non-economic damages cap (Lebron v. Gottlieb 2010). NO punitive damages cap (court discretion, willful/wanton). NO economic damages cap. Plaintiff-friendly framework — only NY and FL have similarly no-cap frameworks among the 5 states. Government entities: immunity under Tort Immunity Act (745 ILCS 10) — generally immune except willful/wanton or failure to repair after actual notice. Gov entity claims have shorter notice windows — consult attorney promptly.

Illinois Medical Malpractice FAQs
Does Illinois have medical malpractice damage caps?
NO. Lebron v. Gottlieb Memorial Hospital (2010) struck down the 2005 caps ($500K physicians, $1M hospitals) as unconstitutional under the IL Constitution's separation of powers clause. The court found caps infringed the judiciary's remittitur authority. Inseverability clause voided ALL provisions of Public Act 94-677. Lebron's logic extends to any future cap attempt. Illinois is one of the few states where jury verdicts can reach full value without legislative constraints.
What is the §5/2-622 expert affidavit requirement?
Under 735 ILCS 5/2-622, every IL med-mal complaint must be ACCOMPANIED at filing by: (1) certificate of counsel stating they consulted with a qualified health professional, (2) written report from that professional finding 'reasonable and meritorious cause' for the lawsuit. Expert must be practicing or teaching in relevant specialty within last 6 years. Failure = MANDATORY DISMISSAL (subject to limited amendment windows). Start expert consultation weeks before filing. Strict IL appellate precedent enforces §5/2-622.
What is the Illinois med-mal SOL?
2 years from knowledge of injury/death under 735 ILCS 5/13-212. 4-year statute of repose from negligent act (absolute bar, subject to fraud/concealment exception). Concealment exception: 5 years from discovery of concealment under §5/13-215. Minors: 8 years from act OR by age 22, whichever sooner. Consult IL med-mal attorney immediately on discovery — discovery-rule cases require careful documentation of when you 'knew or should have known'.
Why are Cook County verdicts so much higher than downstate Illinois?
Demographic + cultural factors: Cook County juries are more racially diverse, more urban, more likely to distrust large institutional defendants (hospitals, insurers). Downstate juries (rural, suburban) trend pro-business + more conservative on damages. Typical differential: 3-5× for same injury. Plaintiff strategy: establish Cook County venue where possible (defendant resides in Cook County, or event occurred in Cook County). Defense strategy: motion for transfer to plaintiff's/event's rural county.
What are typical Illinois medical malpractice settlement values?
Average settlement: $646,921 (Sept 2024 NPDB data — Illinois ranks top-5 nationally). Total IL claims paid Jan-Sept 2024: $212.19M across 328 claims. Recent notable verdicts: $56M (2025 elective liposuction/bleeding); $40M (Advocate Physician Partners negligence); $3.6M (2024 stroke malpractice); $3M (2024 ER misdiagnosis). Cook County cases 3-5× downstate values. No caps + plaintiff-friendly Cook County juries + §5/2-622 quality-filter = top US jurisdiction for high-value med-mal verdicts.
Pending IL Med-Mal Issues
Active legal developments (as of April 2026):
- Cook County (Chicago) produces dramatically higher verdicts than downstate — 3-5× difference for same injuries. $646K average masks geographic split.
- Lebron ruling's logic would invalidate future cap attempts, but no IL Supreme Court ruling has explicitly addressed a new post-2010 cap.
- Expert affidavit §5/2-622 requirements strictly enforced — procedural missteps fatal.
