Medical debt in Illinois is governed by a 10-year statute of limitations (735 ILCS 5/13-206). After this period, creditors cannot sue to collect the debt in court. Illinois also has specific rules on wage garnishment, charity care, and credit reporting that affect how you should handle medical debt.

Statute of limitations on medical debt in Illinois

Under 735 ILCS 5/13-206, the statute of limitations on written contracts (which includes most medical bills) is 10 years in Illinois. The clock starts from the date of last payment or last activity on the account.

Once this period expires, the debt is "time-barred" — the creditor cannot file a lawsuit to force payment. However:

  • The debt still legally exists and collectors can still request payment
  • Making a payment or acknowledging the debt in writing can RESTART the clock
  • The debt may still appear on your credit report for up to 7 years from first delinquency

Wage garnishment rules in Illinois

15% of gross wages or amount over 45x state min wage

Wage garnishment can only occur after a creditor:

  1. Files a civil lawsuit against you
  2. Serves you with a summons and complaint
  3. Wins a judgment (often by default if you don't respond)
  4. Obtains a separate garnishment order

If you receive a lawsuit notice, ALWAYS respond — even just to request more time. Default judgments are the most common path to wage garnishment.

What to do if you have medical debt in Illinois

  1. Request an itemized bill. You have a legal right to one. Audit each line against Medicare rates before paying anything.
  2. Apply for financial assistance. All nonprofit hospitals are required by IRS rules to offer charity care programs. Most cover patients up to 300–400% FPL.
  3. Verify the statute of limitations. If the debt is older than 10 years with no payment activity, it may be time-barred and unenforceable in court.
  4. Negotiate before paying. Medical debt collectors typically buy debt for 5–10 cents on the dollar — they will often settle for 20–40% of face value.
  5. Never ignore a lawsuit. Default judgments are the most common path to wage garnishment. Always respond to court notices even if only to request more time.
  6. If you cannot pay, consider bankruptcy. Medical debt is fully dischargeable in Chapter 7 bankruptcy. Medical bills are the leading cause of personal bankruptcy in the US.
Bottom line: In Illinois, medical debt has a 10-year statute of limitations, and 15% of gross wages or amount over 45x state min wage. Audit your bill first, apply for charity care, and never make a payment on old debt without understanding whether it's time-barred.
