Military beneficiaries that are currently enrolled in TRICARE Reserve Select (TRS) or TRICARE Retired Reserve (TRR) who pay monthly premiums by check will be required to switch to an electronic form of payment before Jan. 1, 2013. If you fail to do so, your account will be automatically cancelled.
TRICARE.mil has stated that “Beginning Jan. 1, 2013, TRICARE will only accept monthly premium payments using recurring automatic payments by credit or debit card, or by recurring electronic funds transfer (EFT) from a linked bank account. To avoid confusion, beneficiaries should verify that their bank sends EFT payments electronically.”
