Competitive Bidding Areas

The Centers for Medicare & Medicaid Services (CMS) consolidated the competitive bidding areas (CBAs) included in Round 1 2017 and Round 2 Recompete by conducting Round 2021 in the same geographic areas for a total of 130 CBAs (listed below). Contracts for off-the-shelf (OTS) back braces and OTS knee braces were not awarded in three of the 130 CBAs where savings would not be achieved (see list below). Please see the CMS announcement for additional information. The CBAs are identified by counties and ZIP codes.

A CBA is an area where only Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) Competitive Bidding Program contract suppliers may furnish competitively bid lead and non-lead items to beneficiaries unless an exception is permitted by regulations. CBAs are based on metropolitan statistical areas, which are areas designated by the Office of Management and Budget, that include major cities and their surrounding suburban areas.

Round 2021 CBAs have nearly the same ZIP codes as CBAs in Round 1 2017 and Round 2 Recompete. However, if certain ZIP codes have changed, we have updated the CBAs to reflect the changes. For example, if a ZIP code within a CBA was split into two new ZIP codes, we included both new ZIP codes in that CBA. Also, if a ZIP code was deleted (no longer valid with the United States Postal Service) from an area, we removed that ZIP code from the CBA. To determine whether a specific ZIP code is included in the competitive bidding program, you may use the Round 2021 ZIP code file below.
