The Costco Difference

Costco is well known for its corporate philosophy of providing goods and services at the lowest net cost, this also extends to our approach to Pharmacy Benefit Management.


Costco Health Solutions is a true “Pass-Through” model PBM. Our sole compensation is an administrative fee with no additional charges. We pass through100% of all rebates and any other sources of revenue. Meaning more savings for you!


You also gain access to Costco Wholesale pharmacies which are well known as the low cost source for prescription medications and no Costco membership is required to use Costco pharmacies.

The goal of the Costco Health Solutions formulary, also known as a preferred drug list, is used to help members and prescribers to make the best medication decision in terms of safety, efficacy, cost effectiveness and overall value.

Ongoing review of new and existing prescription drugs ensures the formulary is up-to-date, and meets the health needs of all patients.
