In a system and method for verifying the accurate processing of medical insurance claim data by one or more health insurance companies, a healthcare provider enters claim data into a provider terminal. The provider terminal transmits the claim data to an insurance claim processor that processes claims for payment on behalf of one or more health insurance companies. Upon receipt of the processed claim data from the insurance claim processor, the provider terminal compares the processed claim data with the claim data originally submitted to the insurance claim processor and generates comparison data indicating whether the original claim data has been processed in accordance with predetermined claim processing rules. The health care provider terminal may also generate and retransmit revised claim data when the processed claim data has not been processed in accordance with the predetermined processing rules or within a defined period of time.
