Choosing your


MSF contracts with Express Scripts to serve as our pharmacy benefit manager. You may choose from any of Express Scripts Participating Pharmacies to get your prescription medications filled. Your pharmacist will process and submit the billing electronically to Express Scripts. When you are picking up your first prescription, please present a copy of the First Prescription Fill Form. Please note, filling prescriptions at non-participating pharmacies may require that you pay for your medications.

Your prescription will be filled with the generic equivalent of the brand-name drug unless it is not the therapeutic equivalent. You may be required to pay the difference between brand-name drugs and the generic product if you choose to use the brand-name product.

If you have questions, please contact your claims examiner at 406-495-5000 or
