Please bring documentation of your primary and secondary insurance carriers with you to your appointment, including address and phone number.

Due to the increasing number of plan restrictions from managed care companies, it is your responsibility to know and be able to provide:

  1. Your primary care doctor
  2. The hospital approved by your insurance plan
  3. The laboratory and X-ray facility approved by your plan
  4. Co-payment amount required by your insurance plan
  5. Referral for service, if applicable

Minimum Payment Expectations

SIU Medicine will collect the co-payment for the services specified by your health insurance plan. If there is a remaining balance after your insurance payment is received, you will receive an invoice for payment by mail.

If you do not have health insurance, we ask for a minimum payment at the time of service.
