“By federal law, if you sign someone up for Medicaid, you also give them the right to vote.”

In January 2026, Mehmet Oz, the administrator of the Centers for Medicare and Medicaid Services, said that under federal law, signing someone up for Medicaid also gives them the right to vote.

That is not how the law works. The 1993 National Voter Registration Act requires states to offer voter-registration services at various public agencies, including those that administer Medicaid. But offering the opportunity to register is not the same as registering someone, and it does not confer the right to vote.

Only U.S. citizens who meet their state's eligibility rules may register and vote. Medicaid enrollment neither registers a person nor changes who is eligible. PolitiFact rated the claim False.
