Medicaid is a type of medical insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether someone qualifies for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify simply because they earn a reasonable income. For example, individuals who have many dependents may be eligible for Medicaid regardless of whether they earn what can certainly be a fair income. Medicaid also can cover the expense of rehab, if someone has been abusing drugs or alcohol and needs treatment. There are numerous alcohol and drug treatment programs which accept Medicaid, but different states have distinct guidelines for what sorts of treatment are covered. Some states only include outpatient treatment services for instance while other states cover far more extensive rehab like a residential stay in long-term alcohol and drug rehabilitation facility. If anyone is involved in drug abuse and needs help, they could use their Medicaid health coverage to get this help. If they don't have Medicaid and in addition don't have the funds or some other kind of health insurance to cover treatment, they could determine if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation facility which is approved in their state.
