Medicaid is a federal program, but it is administered individually by each state. That's why you apply for Medicaid at your state's own Medicaid office, which is usually at a local county social service or social welfare office. To find information about where to apply for Medicaid in your state, go to the Benefits.gov web site and click on the name of your state. This will take you to a page which gives information about the local office where you apply for Medicaid, and tells you how to contact them so you can learn what paperwork – about your income, assets, and medical expenses -- to bring with you when you file your application.
