A PBM is an organization that manages pharmaceutical benefits for employers, managed care organizations or other medical providers. PBM activities may include all or some of the following:
A pharmacy carve-out pharmacy arrangement is when pharmacy benefits are separated from medical benefits and are managed outside of an organization’s primary medical health plan vendor. This approach is self-insured, and an employer works directly with a PBM to administer and manage the pharmacy benefits.
A pharmacy benefit group purchasing employer coalition leverages their members’ combined purchasing power to obtain maximum discounts from their PBM vendor partners for all its members. The group’s collective buying power far exceeds what any one company can generate on its own and can provide savings by being a part of the coalition. In addition, the combined size leads to better account management and services. What differentiates the Rx Collaborative in the market are the superior services and expertise available to its members.
