Medicaid is a form of health care insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether a person qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify simply because they earn a good income. By way of example, men and women who have a lot of dependents may be eligible for Medicaid even if they earn what would be considered a reasonable income. Medicaid could also cover the expenses of rehabilitation, if a person has been abusing drugs or alcohol and requires treatment. There are lots of drug and alcohol rehabilitation programs which accept Medicaid, but different states have different rules for what kinds of treatment are covered. Some states only cover outpatient rehab services as an example while other states cover far more intensive treatment say for example a residential stay in long-term drug and alcohol rehabilitation facility. If somebody is involved in drug use and desires help, they can use their Medicaid insurance coverage to obtain this treatment. If they do not have Medicaid plus don't have the funds or some other type of medical health insurance to cover treatment, they could check if they are eligible for a Medicaid and then enroll in a drug treatment facility that is approved in their state.
