How often does Medicaid have to be renewed, and what if my Medicaid was ended?

This is the federal rule for people whose Medicaid is based on MAGI income methods. Eligibility must be renewed once every 12 months, and no more often than that [1]. If the state can renew you from information it already has, it must do so without asking you for more. It must then tell you the decision and why [1].

If it can't, it must send you a renewal form with the facts it has. You get at least 30 days from the date of the form to respond [1]. If your Medicaid ends because you did not send the form or information, the state must look at your eligibility again if you send the renewal form within 90 days after the date of termination. A state may choose a longer period [1]. The sources here do not cover the rules for people whose Medicaid is not MAGI-based.

Your state Medicaid agency sets the form and the way to send it. If your Medicaid ended, the notice also tells you how to ask for a hearing — "Don't know yet" the steps here.
