My medicaid has been closed and have to recertify want to know how to do so by mail? Is there an official website where it can be downloaded.

What state?- usually there is a form (PDF file) that you can fill in, print and mail. You just want to make sure you have all of your documentation to go along with the form to not delay the process. The form is usually specific for the state since each state governs its Medicaid program.
