  1. DRG = Diagnosis Related Group. DRG Relative Weight × Base Rate = Medicare payment. The drop in DRG relative weight with Medicare patients was 0.7264. Multiplied by St. Francis Hospital Base Rate of ~$5234 (average of $5171 for fiscal 2005 and $5297 for fiscal 2006) corresponds to reduction in payment of ~$3802 per admission for Medicare patients.
