Geographic Adjustment in Medicare Payment: Phase I: Improving Accuracy

Medicare is the largest health insurer in the United States, providing coverage for 39 million people aged 65 and older and 8 million people with disabilities, and reaching more than an estimated $500 billion in payments in 2010. Although Medicare is a national program, it adjusts fee-for-service payments according to the geographic location of a practice. While there is widespread agreement about the importance of providing accurate payments to providers, there is disagreement about how best to adjust payment based on geographic location.
