An exemplary method for determining the appropriateness of service provider claims for payment includes scheduling appointments for patients with service providers based on requests for services, generating appointment information corresponding to each of the scheduled appointments, and capturing service information corresponding to claims received from the service providers for payment of charges associated with services rendered by the service providers to the patients. The method further includes automatically identifying candidate appointments that correspond to a particular received claim based on a degree of similarity between the service information associated with the particular received claim and the appointment information associated with the scheduled appointments. Additionally, the method includes flagging the particular received claim for resolution when none of the candidate appointments corresponds to the particular received claim, and presenting the particular received claim for payment when at least one of the candidate appointments corresponds to the particular received claim.
