Illinois Medical Debt Statute of Limitations: 2 Years with Key Exceptions

In Illinois, the statute of limitations (SOL) for written contracts—including medical bills—is 2 years from the date of default (typically the date of service or last payment).

Core Rule

  • 735 ILCS 5/13-202: Actions on written contracts must be commenced within 2 years.
  • After SOL expires, the debt is time-barred—creditor cannot obtain a court judgment, but the debt still exists and may be reported to credit bureaus (7 years per FCRA).

Important Exceptions Extending the SOL

  • Minors (735 ILCS 5/13-211): SOL tolled until age 18 → effectively 2 years after 18th birthday (total up to ~20 years from service).
  • Motor vehicle accident claims (735 ILCS 5/13-202.1): 5 years for claims arising from motor vehicle accidents (includes medical bills from MVA treatment).
  • Written acknowledgment or partial payment (735 ILCS 5/13-214): Any signed written acknowledgment of the debt or voluntary payment restarts the 2-year clock from that date.
  • Judgment: If creditor sues and wins within SOL, judgment is enforceable for 20 years (renewable).

What the SOL Does NOT Do

  • Does not erase the debt.
  • Does not prevent collection attempts (calls, letters)—only lawsuits.
  • Does not remove from credit report (7 years from delinquency per FCRA).

Consumer Protections

  • FDCPA prohibits threatening legal action on time-barred debt.
  • Illinois Collection Agency Act requires licensing and regulates conduct.
  • If sued on time-barred debt, raise SOL as affirmative defense in court response.

Practical Advice

  1. Request itemized bill and verify dates of service.
  2. Check if insurance should have paid (timely filing, coordination of benefits).
  3. Negotiate settlement (often 30–50% of balance) if within SOL.
  4. If outside SOL, do not make payment or written acknowledgment without legal advice—it revives the debt.
  5. Consult an Illinois consumer law attorney for specific situations.

Note: This applies to Illinois law only. Other states range from 3–10 years for written medical contracts.
