Medicaid is a type of medical insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether a person qualifies for Medicaid doesn't only depend on income however, and individuals shouldn't presume they don't qualify simply because they make a fair income. For example, people who have a lot of dependents may be eligible for Medicaid even when they make an amount be described as a reasonable income. Medicaid can also cover the expenses of rehabilitation, if someone has been abusing alcohol or drugs and needs rehabilitation. There are lots of alcohol and drug treatment programs which accept Medicaid, but various states have different guidelines for what forms of rehabilitation are covered. Some states only include outpatient rehab services as an example while other states cover more extensive rehab like a residential stay in long-term drug treatment program. If a person is involved in substance abuse and wants help, they could use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and in addition don't have the money or some other form of health care insurance to cover treatment, they could see if they are eligible for a Medicaid and then enroll in an alcohol and drug rehabilitation program that is approved within their state.
