Methods and systems for requesting and delivering supporting documents to an insurance carrier to enable the carrier to process an insurance claim for services rendered by an institutional health care provider. Hard copies of supporting documents are converted to electronic images that are accessible by the carrier through the Internet, thereby eliminating the need for communication between the provider and the carrier through regular mail. The images are indexed based upon the insurance claim, the provider, the patient, and/or the carrier to enable the carrier to access the images associated with a specific insurance claim efficiently. In addition, the insurance claim can be pre-adjudicated prior to delivering the claim to the carrier for processing and can be approved and paid before the carrier processes the claim.
