DATA PROCESSING SYSTEM FOR ACCURATELY CALCULATING A POLICYHOLDER'S DISCOUNT IN A MEDICAL INSURANCE PLAN AND A METHOD THEREFOR

A data processing system for accurately calculating a discount in a medical insurance plan comprises a premiums module adapted to access data regarding the amount of premiums paid by a policyholder of the medical insurance plan for a predetermined period. A claims module is adapted to access data regarding the amount of claims paid by the medical insurance plan to the policyholder for the predetermined period, the claims module being further adapted to access data to determine if there have been any claims submitted by a policyholder which have not yet been paid, and if so to apply a set of rules to each submitted claim which has not been paid to determine if it is likely to be paid, and if the claim is likely to be paid then adding the amount of the claim to the amount of claims already paid for the predetermined period. Finally, a discount module adapted to receive data from the premiums module and the claims module and to use the data to calculate a discount amount.
