St. Peter's Health accepts most major insurances but may not be contracted with them all. To verify if we are in-network with your specific insurance, contact your insurance carrier.

Patients are expected to furnish all the necessary health insurance information and sign the medical release and insurance assignment authorizations. St. Peter’s Health will submit complete insurance claims on the appropriate forms for the charges recorded. 

Keep in mind that insurance is a contract between the patient and his or her insurance company and that St. Peter’s Health is acting only as a billing agent. St. Peter’s Health cannot pursue payment from insurance carriers in the event of non-payment or benefit denials. If a patient’s insurance carrier has not submitted payment within 30 days of billing, St. Peter’s Health expects the patient to pay the balance in full. Patients receive a monthly statement showing any account activity and the remaining balance due.
