PIS and DRGs: coding inaccuracies and their consequences for resource management.

Accurate information is important for the successful implementation of the Resource Management Initiative and the NHS White Paper. A review of 153 joint replacements performed in a three-month period in Leicester showed that 24 per cent of 139 procedures for which medical notes were available had been given incorrect Diagnosis-Related Groupings (DRGs). Of these, 64 per cent could be ascribed to errors in allocating OPCS-3 codes and 36 per cent to errors in converting OPCS-3 codes to DRGs by computer. It is of concern that inaccurate information may in future be used to allocate resources. The resource implications of assiduous quality control of recording, coding and computing is pointed out, and it is suggested that improved classification systems should be assessed for use in the NHS.
