Medicaid is a kind of medical insurance available for those who are in specific income brackets which qualifies them to obtain this government funded insurance coverage. Whether or not an individual qualifies for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify just because they earn a fair income. For example, people who have many dependents may be entitled to Medicaid even though they earn what can certainly be a reasonable income. Medicaid may also cover the expenses of treatment, if a person has been abusing drugs or alcohol and requires treatment. There are several drug and alcohol treatment facilities which accept Medicaid, but different states have distinct guidelines for what forms of rehabilitation are covered. Some states only include outpatient treatment services for example while other states cover far more extensive rehab like a residential stay in long-term drug treatment facility. If somebody is involved in substance abuse and wants help, they can use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid and also don't have enough cash or another form of health insurance to cover treatment, they can see if they are eligible for a Medicaid and then enroll in a drug and alcohol rehabilitation facility that's approved in their state.
