How can I manage my payments?

Express Scripts offers easy payment plans to help you pay for your medications. The Extended Payment Program (EPP) allows you to use a credit or debit card to pay in three equal monthly installments with no service fee for Home Delivery orders. Once enrolled in the program, an EPP payment schedule is provided at checkout.

Additionally, you can sign up for Autopay and Express Scripts will automatically deduct payment for your prescription orders.

To sign up for Autopay:

  1. Go to Payment information under Account in the navigation menu at the top of your screen.
  2. Chose Edit information on the right side of the page.
  3. Enter your payment information.
  4. Turn on Autopay by switching the toggle button to on.

If you want to use an option other than Autopay, you'll need to submit payment information each time you order a prescription or pay your bill online or through the mail. If you are enrolled in the EPP, you can’t turn on Autopay.
