OmptumRx replaces Caremark prescription drug program on January 1

The Employees Retirement System of Texas (ERS) Board of Trustees awarded the third-party administrator contract for the HealthSelect Prescription Drug Program to OptumRx, an affiliate of UnitedHealthcare, Inc. The four-year contract runs from January 1, 2017 through December 31, 2020. Caremark will continue to administer the prescription drug plan through December 31, 2016.

Here are a few important things you should know about the transition to OptumRx:

  • In late December, UnitedHealthcare will send a new combined medical and prescription benefits ID card with OptumRx information to participants.
  • Participants can start using the new card on January 1, 2017.
  • Participants who currently use the prescription mail service should have at least a two-month supply of any medication they take regularly to ensure they are covered during the transition.
  • Optum’s mail service pharmacy will be available beginning January 1, 2017. Participants with any active, refillable mail service prescriptions with Caremark will be transferred to Optum in January.
  • Participants should watch the mail for notifications from OptumRx about prescription drug coverage and benefits as well as any action they may need to take.
