Abstract: A method of programmatically retrieving and processing electronically posted medical bill payments is disclosed. Electronically posted payment information is programmatically retrieved, parsed into a pre-determined format and stored in a permanent database. The information is subsequently retrieved from the database/storage location and reformatted to meet individual medical provider requirements compatible with the medical provider's internal billing systems. The retrieved payment information is used to update the billing records for previously submitted claims from the medical provider. Data is parsed into transaction level, claim level and service level information. Information on denials of payment and partial payments for submitting claims is stored in the permanent database and later utilized to generate Explanation of Benefit report needed to re-submit the medical claims to the same or different medical carrier.
