3. Seniors 65 years of age and over. People in this category are usually covered by Medicare, a health insurance program of the federal government.

4. Disabled People. If you're permanently disabled, there's a good chance you can qualify for Medicare.

5. Immigrants Needing Emergency Care. If you have a medical emergency, you might be eligible for a state-funded Alien Emergency Medical Program (AEM) which can pay for your emergency care.
