The full explanation.

The simple version

Applying for Medicaid is free and can be done at any time of year. There are two main ways to apply, and help is available so you do not have to do it alone. Gathering a few documents ahead of time makes the process smoother.

Where to apply

You can apply two ways:

  • Directly through your state's Medicaid agency — by phone, online, by mail, or in person
  • Through the Health Insurance Marketplace at HealthCare.gov, which forwards your information to your state if you may qualify

What to gather

You will usually need proof of income (such as recent pay stubs or tax records), identity, residency, and household size. Exact requirements vary by state, so check your state's list before you start. Having these ready can speed up the decision.

Medicaid applications are accepted year-round — you never have to wait for an enrollment window.

Get help and ask about backdating

Hospital social workers, patient navigators, and Marketplace assisters can help you apply at no cost. If you qualify, ask whether your coverage can be backdated to help with recent medical bills — many states allow some retroactive coverage.
