Blue Shield of California Rolls Out New PBM Model as Other Plans Mull Similar Option

  • Jan 09, 2025

    Blue Shield of California on Jan. 1 rolled out a pharmacy benefits model that uses five vendors to handle various duties, representing a major shift from using CVS Caremark as the insurer’s sole PBM. Pharmacy benefit experts tell AIS Health that other health plans are considering a similar unbundled approach, although they say the switch from one PBM to multiple vendors can be time-consuming and complex. 

    Blue Shield announced the transition in August 2023 for its commercial and Medicare lines of business. The company is contracting with four new vendors: Amazon.com Inc.’s online pharmacy manages online and mail-order fills; Mark Cuban Cost Plus Drug Co. manages retail pharmacy pricing and payment; Abarca Health LLC handles claims management and rebate processing; and Prime Therapeutics LLC negotiates with manufacturers. Meanwhile, Caremark continues to administer specialty medications under the medical benefit.
