Express Scripts will be the administrator for the HealthSelectSM Prescription Drug Program beginning Jan. 1, 2024

HealthSelect Prescription Drug Program logo

In December, the ERS Board of Trustees awarded the third-party administrator contract for the HealthSelectSM Prescription Drug Program and HealthSelectSM Medicare Rx to Express Scripts. The six-year term of the contract is Jan. 1, 2024 through Dec. 31, 2029.

What the change means for participants

Participants in the non-Medicare HealthSelect of Texas® plans are automatically enrolled in a comprehensive prescription drug program. Employees, non-Medicare retirees and their eligible dependents enrolled in HealthSelectSM of Texas, HealthSelectSM Out-of-State, and Consumer Directed HealthSelectSM do not need to re-enroll because of this transition. They will be automatically transferred to Express Scripts on Jan. 1.

In December, Express Scripts will send you two new ID cards included in the welcome packet to use starting Jan. 1, 2024

Why ERS is making the change

ERS is required to rebid the administration of its benefit programs on a regular basis to ensure we are providing competitive benefits at a reasonable cost. Express Scripts’ proposal included costs that were considerably lower than the other bidders. In fact, Express Scripts’ bid was almost $470 million lower than the next lowest bidder, while maintaining current coverage levels and high-quality service.

In-network pharmacies

Express Scripts has a network of over 60,000 retail pharmacies you can use. For maintenance medications (medications you take long-term), you can get up to a 90-day supply at an Extended Days’ Supply Retail pharmacy or Express Scripts Mail Order pharmacy through Express Scripts® Home Delivery. Express Scripts has mail order for specialty medications with Accredo.

Call center

Express Scripts call center is now available toll-free at (800) 935-7189 (TTY: 711), 24 hours a day, 7 days a week. Representatives can answer general questions about the transition, plan benefits, the new formulary and pharmacy network.
