Competitive Acquisition Ombudsman (CAO)

Mission

Provide quality responses to DMEPOS suppliers and individuals and unbiased reporting to Congress.

Overview of the Competitive Acquisition Ombudsman

The Competitive Acquisition Ombudsman (CAO) was created as part of the Medicare Improvements for Patients and Providers Act of 2008 (MIPPA) Section 154(b) to respond to inquiries and complaints made by suppliers and individuals relating to the application of the Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) Competitive Bidding Program. The CAO program falls under the leadership of the Office of the Medicare Beneficiary Ombudsman, which is responsible for resolving inquiries and complaints for all aspects of the Medicare program.

The CAO works with the local Competitive Bidding Implementation Contractor (CBIC), a source for assistance in resolving complaints made by suppliers and individuals.

The CAO, in coordination with the Office of the Medicare Beneficiary Ombudsman, is also required to submit an annual report to Congress that includes the CAO's findings and if appropriate, recommendations for improvements to the application of the Competitive Bidding Program.

The Role of the Competitive Acquisition Ombudsman (CAO)

The CAO works closely with CMS components and its contractors, as well as with external partners, to:

  • Respond to suppliers' and individuals' inquiries and complaints;
  • Ensure that issues are resolved; and
  • See that a comprehensive process for timely responses to suppliers and individuals is in place.
