Abstract
To explore the relationship between commercial health care prices and Medicare spending/utilization across U.S. regions. Claims from large employers and Medicare Parts A/B/D over 2007–2009. We compared prices paid by commercial health plans to Medicare spending and utilization, adjusted for beneficiary health and the cost of care, across 301 hospital referral regions. A 10 percent lower commercial price (around the average level) is associated with 3.0 percent higher Medicare spending per member per year, and 4.3 percent more specialist visits (p < .01). Commercial health care prices are negatively associated with Medicare spending across regions. Providers may respond to low commercial prices by shifting service volume into Medicare. Further investigation is needed to establish causality.Keywords
