The G-DRG system 2008 once again brings many changes to rheumatological departments in Germany. The following article presents the main general and specific changes in the G-DRG system, as well as in the classification systems for diagnoses and procedures and in invoicing for 2008. Since the G-DRG system is only a tool for the redistribution of resources, every hospital needs to analyze the economic effects of the system by applying the G-DRG transition grouper to its own cases. Depending on their clinical focus, rheumatological departments may experience positive or negative effects from the system's application. The strain placed on hospitals by the inadequate funding of increased costs needs to be assessed separately from the effects of redistribution by the G-DRG system.
