A glitch that caused the online method of enrolling and switching Tricare plans is expected to last for the entire open season. Those who made an adjustment online in the first week before the glitch occurred are urged to call Tricare and confirm the changes. Officials warned that they are unsure of how many previous changes were affected before the glitch came into full affect, leaving those unaware with a possible change or gap in their coverage. Those who wish to remain in their current Tricare plan do not need to call. Beneficiaries who want to switch between Tricare Prime and Select are required to call even if one already did it online earlier this season.
