You can choose how to get your maintenance medications. Most plans allow you to choose to get your medications from a Military Treatment Facility, a retail network pharmacy, or through TRICARE Home Delivery Pharmacy Program. But, some plans require you to use delivery for certain medications. We’ll alert you if your medication has restrictions on your pharmacy location. Express Scripts Pharmacy offers delivery of up to a 90-day supply of your medication to any location. You can track your order online or through the Express Scripts mobile app. We also offer an optional 3-month payment plan. And, you have access to an Express Scripts pharmacist at any time, 24/7.
