Abstract: A medical claim verification and processing system reads a medical information card (MEDICARD) to determine a patient's background medical and insurance information. The validity of the card is rapidly determined by accessing a central brokerage computer. A local service provider enters into a local terminal the medical and MEDICARD information services provided or to be provided to the patient by using a patient service code and transmits this information to a central brokerage computer. The central brokerage computer converts the patient service code input by the service provider or MEDICARD into a particular service code for the patient's insurance carrier. This service code is then utilized to determine the insurance claim payment for that particular patient service. The claim payment amount for the medical service is then transmitted back to the local entry terminal for use by the service provider and patient.
