Where can states find a list of the Medicare competitive bidding areas (CBAs), including zip codes and areas of the state, and how does a state find out if it has CBAs?

States may review Medicare’s CBAs through the following website for the most up-to-date information: www.dmecompetitivebid.com. In the alternative, the Center for Medicaid and CHIP Services (CMCS) has a list of states and CBAs by state that is available upon request. We will monitor the lists and update them with any necessary Medicare changes. As of January 1, 2018, the following states and territories do not have CBAs: Alaska, Maine, Vermont, North Dakota, South Dakota, Montana, Wyoming, and all of the US territories.
