Online referral guides


Patients with HMO and PPO are expected to obtain a referral for the visit, if required by their plan. The co-payment specified by the plan will be collected at the time of service. Please have your patient familiarize themselves with their specific coverage to understand their payment obligation. They should contact their insurance company to determine their plan's specific requirements and coverage options.


SIU Medicine participates with Medicaid programs of Illinois and Missouri. If your patient is from one of these states and has out-of-state prior authorization restrictions, the patient should contact their program directly to complete these requirements. Except in emergency situations, SIU Medicine will not provide care to Medicaid patients from other states unless financial arrangements are made in advance.

Medicaid patients are required to bring their current medical assistance card. If their plan requires a co-payment, it will be collected at the time of service. If the patient does not have his or her card, we may not be able to verify plan eligibility and the patient will be considered self-pay.
