Abstract: A centralized formulary system for maintaining formulary data to service the needs of multiple user groups. Formulary and drug information is updated automatically when received from outside sources. In addition to drug identifying data, line of business and utilization management protocol data is associated with the formulary data. The formulary data further comprises coverage data for health plans that use the formularies. The additional business data maintained in association with the formularies facilitates the retrieval and editing of formulary data for various business needs, including compliance with third party requirements. The system allows users to analyze formulary data, edit formulary data, produce reports regarding formulary data, and export files. The system also supports submission of formulary data to third party computer systems.
