A method for identifying charge capture opportunities comprises steps of receiving and storing in a server computer at least one itemized bill and at least one final bill, comparing the final bill to the itemized bill to identify line item discrepancies between the bills, comparing either or both bills to a Charge Description Master (CDM) to identify discrepancies between line items of the bill and correct charges defined in CDM, and evaluating final bill according to a set of rules to identify potential missing charges associated with billed charges. Additionally or alternatively, itemized charges can be evaluated according to the rules to identify potential missing charges. Potential missing charges are displayed to a user as revenue opportunities for correction of the bill or other remedial action.
