The Centers for Medicare & Medicaid Services today launched a new online tool that allows consumers to compare Medicare payments and copayments for certain procedures that are performed in both hospital outpatient departments and ambulatory surgical centers. The Procedure Price Lookup tool displays national averages for the amount Medicare pays the hospital or ambulatory surgical center and the national average copayment amount a beneficiary with no Medicare supplemental insurance would pay the provider. "Working with their clinicians, the Procedure Price Lookup will help patients with Medicare consider potential cost differences when choosing where to have a medical procedure that best meets their needs," said CMS Administrator Seema Verma.
