Believe it or not, the current Medicaid requirements are not consistent from one state to another. Since the Federal government does not clearly state rules for accepting or denying individuals for the Medicaid health program, it is largely left up to the states to set their own guidelines.
There are some guidelines from the Federal government which tell the states who they absolutely must cover, but they do not list general guidelines beyond that for denying or accepting most people. Each state must grant coverage to individuals qualified under the Federal rules, but everyone else is left up to the individual state's policies.
Two of the most common ways to automatically be qualified for the Medicaid program is to receive Federal income assistance of some variety or to prove that you are at or below 133% of the current national poverty level. This isn't the same as Medicare coverage, which is a different program all to together.
Instead of trying to decipher the rest of the complicated guidelines the Federal government has set to ensure groups of people are automatically covered, you should contact your local Social Services or Medicaid office to inquire whether you are eligible for free medical benefits.
When you contact your local office or set an appointment to apply, make to ask about any other State operated programs which may be of help to you. Often, states have their own programs which are designed to pick up people who do not qualify for Medicaid and give them the help they really need.
Most people who qualify under the current Medicaid requirements will also qualify for other services through the state or federal government. This may include food stamps, housing, and other basic living needs. The only way to determine whether you qualify any of these types of services is to walk into your local Social Services agency or make an appointment with someone in that office.
