Abstract: A pharmacy contribution management method comprises analyzing historical claim data, determining a tiered model for prescription contributions, the tiered model describing a plurality of prescription cost tiers and recommended prescription contribution for each of the plurality of prescription cost tier, permitting an organization to determine a prescription contribution for each of the plurality of prescription cost tier, enabling a member associated with the organization to shop of lowest price drugs via pass-through pricing from the pharmacies, receiving a prescription claim from a pharmacy arising from a prescription purchase by the member associated with the organization, and transmitting the prescription contribution for the organization to the pharmacy, so that the pharmacy may charge the member an amount equal to a price of the prescription minus the organization's prescription contribution.
