Prime Therapeutics LLC (Prime)1 has been selected by Boeing as your new pharmacy benefit administrator. We are pleased to be entrusted with your care and are committed to providing outstanding service, pharmacy expertise and convenience for you and your eligible family members. Prime will replace Express Scripts,® and this change will take effect on January 1, 2021.

Prime is collectively owned by several Blue Cross and Blue Shield plans, subsidiaries or affiliates of those plans, including the main administrator of Boeing-sponsored medical plans — Blue Cross and Blue Shield of Illinois (BCBSIL). Today, Prime provides pharmacy benefit management services for over 30 million members across many medical plans. For Boeing, we’ll provide pharmacy benefit management services for these Boeing-sponsored plans: all medical plans administered by BCBSIL, plus Cigna HMO and Aetna HMOs (except the Aetna HMO in Kansas). We’ll offer you services and features that are similar to those you have had with Express Scripts — a large national network of retail pharmacies, a home delivery (mail order) and specialty pharmacy and a drug list that’s comparable to your current list. Plus, you’ll find new features like the opportunity to get up to a 90-day supply of medications at over 54,000 retail pharmacies.
