The Center for Medicaid and CHIP Services (CMCS) is committed to working in close partnership with states, as well as providers, families, and other stakeholders to support effective, innovative, and high quality health coverage programs. Medicaid and the Children’s Health Insurance Program (CHIP) are joint federal/state programs for which state Medicaid/CHIP agencies have full responsibility for all aspects of the administration and operation of the Medicaid program in their state, including determining eligibility for and enrollment into their programs.

How to apply for Medicaid

Eligibility Requirements

Medicaid eligibility criteria vary from state to state. Many states have expanded their Medicaid programs to cover more low-income adults. If you are unsure if you might qualify for Medicaid, you should apply. You might be eligible depending on your household income, family size, age, disability, and other factors. You must be a United States (U.S.) citizen, a U.S. national, or have a satisfactory immigration status to be eligible for full benefits. Visit HealthCare.gov to take a quick screening to help you determine your eligibility for Medicaid/CHIP or other health insurance options.

Application Process

You can apply for Medicaid through the Health Insurance Marketplace or directly with your state Medicaid agency. Don’t wait.
