Variation in Payment Rates under Medicare's Inpatient Prospective Payment System.

Objective

To measure variation in payment rates under Medicare's Inpatient Prospective Payment System (IPPS) and identify the main payment adjustments that drive variation.

Data sources/study setting

Medicare cost reports for all Medicare-certified hospitals, 1987-2013, and Dartmouth Atlas geographic files.
