Abstract: A method and system is provided to review and control clinical data quality in the reporting of hospital claims data. The method and system perform data quality checks and generate turn-around documents that establish communications between coders and physicians in order to obtain the best description of a case for reporting purposes. The system provides file security and tracks cases through the entire review process to final reporting. Patient data and system performance data are aggregated into a common data base. From this integrated data base, a variety of summary reports are generated to identify systematic problems in data quality and to assess the success of the data correction process. The system interfaces with existing data systems to optimize the performance efficiency of a total health information system functioning within a hospital or within third-party claims review organizations including payers of hospital claims.
