Abstract: In one embodiment, a document management system is provided that automatically converts documents submitted electronically with or for a claim into a format that is required by a third-party payor. The document management system maintains a list of document format and delivery preferences for each third-party payor. Rather than submit a claim and document directly to the third-party payor, the submitter submits the claim and document to the document management system using a portal that accepts a wide variety of electronic document formats. The document management system then retrieves the format and delivery preferences of the third-party payor and converts the documents into whatever format is required by the third-party payor. The document management system then delivers the converted document to the third-party payor according to the delivery preferences such as email, fax, or regular mail.
