TRICARE E-Payment Enrollment Deadline

Week of May 20, 2013

Beneficiaries enrolled in TRICARE Reserve Select or TRICARE Retired Reserve who pay monthly premiums by check must switch to an electronic form of payment by May 31 to avoid losing coverage. TRICARE will only accept monthly premium payments using recurring automatic payments by credit or debit card, or by recurring electronic funds transfer from a linked bank account. To avoid confusion, beneficiaries should verify that their bank sends EFT payments electronically. Beneficiaries can contact their regional contractor to set up automatic payments and obtain more information. Contact information for each region is available on the TRICARE website at Contact Us.
