In January 2021, the Centers for Medicare and Medicaid Services (CMS), passed a “rule” that requires all hospitals to provide a shoppable list of prices for three hundred inpatient procedures. I use this newly available data to examine prices at the Albany Medical Center (AMC) and New York Presbyterian (NYPH) hospitals. I find significant price variation across hospitals, service class, and payor class. Additionally, there is significant interaction between hospital and service class, hospital and payor class, and service class and payor class. The data shows that evaluation and
management services were over 25 percentage points more expensive at NYPH than at AMC and that radiological and laboratory services were 136 and 134 percentage points less expensive at AMC than at NYPH. Surgical services are over 40 percentage points less expensive and AMC than NYPH. Medicare and Medicaid payors paid approximately 50 percentage points less than Commercial and Exchange payors for Evaluation and Management Services and even less for the other service classes. Exchange payors were found to pay prices that were 20 percentage points more expensive at NYPH than at AMC. These patterns do not easily fit models of market power or economies of scale.
