CMS is pleased to announce the Certified Application Counselor Designated Organization (CDO) Application web form is now live and will remain available year-round!

CDOs are a vital component of the assister community. In states with a Federally-facilitated Marketplace (FFM), CDOs oversee Certified Application Counselors (CACs), who are annually trained and able to help consumers seeking health coverage options through the Marketplace.

Help us spread the word – the Centers for Medicare & Medicaid Services (CMS) invites new applicant organizations who want to become CDOs to apply.
