IDX Systems Corporation was a healthcare software technology company that formerly had headquarters in South Burlington, Vermont, United States. It was founded in 1969 by Robert Hoehl, Richard Tarrant, and Paul Egerman. IDX was acquired by General Electric and incorporated into its GE Healthcare business unit in 2006. Prior to its acquisition by GE Healthcare, IDX had four primary lines of business: Flowcast was the original application produced by IDX. It is a revenue cycle management system for medium to large physician groups, hospitals, and integrated delivery networks, and includes... scheduling, billing and collections modules. It is written in the MUMPS programming language and runs on InterSystems Caché. Groupcast was a financial management system for smaller provider groups. Carecast was a system used primarily by large hospitals and medical centers as an integrated clinical and financial application. Known as "Lastword" before IDX re-branded it, the system was developed in the 1980s by Seattle-based PHAMIS, Inc., a company acquired by IDX in 1997. Carecast also came in a regionalized version currently used at the University College Hospital in London.
