Medicaid is a form of health care insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether an individual qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't presume they don't qualify because they earn a good income. As an example, people who have many dependents may qualify for Medicaid even though they earn what might certainly be a sensible income. Medicaid can also cover the price of treatment, if a person has been abusing drugs or alcohol and requires rehab. There are lots of drug and alcohol rehabilitation facilities which accept Medicaid, but different states have different rules for what kinds of treatment are covered. Some states only cover outpatient rehabilitation services for example while other states cover more extensive treatment say for example a residential stay in long-term drug rehabilitation program. If someone is involved in substance abuse and wants help, they're able to use their Medicaid insurance coverage to obtain this help. If they do not have Medicaid and in addition don't have the money or any other kind of medical health insurance to cover treatment, they can check if they are eligible for a Medicaid and then sign up for a drug and alcohol rehabilitation facility which is approved in their state.
