CMS has posted data on hospital charges associated with the 100 most common Medicare inpatient stays. In a fact sheet announcing the availability of the data, CMS highlighted the “significant variation in charges from hospital to hospital -- including those within the same community -- for inpatient services that may be provided in connection with a given inpatient stay.” For instance, a CMS fact sheet notes that the range in average inpatient charges for services associated with joint replacement (MS-DRG 470) range from $5,300 to $223,000.
