Ensure Prescription Accuracy When Using TRICARE Pharmacy Home Delivery

Beneficiaries who use TRICARE Pharmacy Home Delivery not only save money but also receive prescription medications conveniently at their door. More than 1 million prescriptions ship monthly through Home Delivery, but there are times when a prescription can’t be filled and the order must be returned to the provider or beneficiary.

The main reason for returned prescriptions is missing information like date of birth or address, requiring clarification from the beneficiary or physician. If any information is missing Express Scripts will contact the prescriber and beneficiary to get the information before returning the prescription. Prescriptions can also be returned or denied if the medication is not covered. To find out if a medication is covered, call the TRICARE pharmacy contractor Express Scripts at 1-877-363-1303 or check the formulary search tool at

It can be frustrating to receive a returned prescription or an “unable to fill” letter. Here are some suggestions to help avoid having a prescription returned:

  • Ask the physician to send prescriptions electronically to TRICARE Pharmacy Home Delivery.
  • If submitting a prescription by mail, make sure the patient’s name, date of birth, mailing address and the sponsor’s Social Security number or Department of Defense benefits number are clearly written on the back of the prescription.
  • Beneficiaries who receive a message from Express Scripts about their prescription should contact Express Scripts as soon as possible to find out what is needed to get their prescription filled.

TRICARE Pharmacy Home Delivery is the least expensive option when not using a military treatment facility pharmacy. There are no shipping costs, and refills are easily ordered online, by phone, mail or mobile app. Home Delivery also gives convenient notifications about order status, refill reminders and assistance with renewing expired prescriptions.
