Action Plan
  Yes No If yes, how could the problem be corrected? Responsibility Estimated Date of Completion
1. Have we lost patients to a new hospital or new service at another hospital? Would the loss of those patients have contributed to a fall in case mix?          
2. Did we implement any significant changes in documentation practices? If so, could those practices have contributed to inaccurate or incomplete coding and a fall in case mix?          
3. Did any physicians move away, taking their patients with them? Could the loss of these patients have contributed to a fall in case mix?          
4. Have there been changes in the practice of medicine that have resulted in inpatient procedures being performed in the outpatient arena. Could this change have contributed to a fall in case mix?          
5. Have there been changes in codes or the DRGs to which those codes are grouped? Could these changes have contributed to a fall in case mix?          
6. Have there been changes to the registration process that resulted in higher rejection rates or backlogs? Could such problems have contributed to a roller coaster effect in case mix?          
7. Has there been a decline in coding accuracy that could have contributed to the fall in case mix?          
8. Have there been significant backlogs in coding? Could those backlogs have contributed to a roller coaster effect in case mix?
