Medicaid is a health care insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether someone qualifies for Medicaid doesn't only depend upon income however, and individuals shouldn't presume they don't qualify just because they make a fair income. For example, people who have quite a few dependents may be eligible for Medicaid regardless of whether they earn what might be considered a fair income. Medicaid also can cover the expense of rehab, when someone has been abusing drugs or alcohol and needs treatment. There are lots of drug rehabilitation centers which accept Medicaid, but different states have different guidelines for what forms of rehab are covered. Some states only include outpatient treatment services as an example while other states cover more intensive rehab such as a residential stay in long-term drug and alcohol rehabilitation center. If somebody is involved in drug abuse and wants help, they are able to use their Medicaid health coverage to obtain this treatment. If they do not have Medicaid and in addition don't have enough cash or some other type of medical health insurance to cover rehabilitation, they can find out if they are eligible for a Medicaid and then enroll in an alcohol and drug treatment facility that's approved within their state.
