Your hospital is reviewing its DRG coding patterns for Medicare. It has focused on two DRGs: 640 (Misc disorders of nutrition, metabolism, fluids/electrolytes w MCC) and 641 (Misc disorders of nutrition, metabolism, fluids/

electrolytes w/o MCC). There were 100 patients assigned to these two DRGs: 50 to 640 and 50 to 641.

National averages suggest that 85 should have been assigned to DRG 640 and 15 to DRG 641.

Assuming an average payment of $6,000 per DRG with a case weight of 1.0, how much lost payment from Medicare may be resulting from poor coding and documentation? Use case weight values from Appendix 3-A.
