Medicaid is a kind of medical insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether someone 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 reasonable income. For example, men and women who have quite a few dependents may qualify for Medicaid even when they make what would certainly be a sensible income. Medicaid could also cover the expenses of rehab, when someone has been abusing drugs or alcohol and needs treatment. There are lots of drug rehabilitation programs which accept Medicaid, but different states have different guidelines for what forms of rehabilitation are covered. Certain states only cover outpatient rehab services for example while other states cover more extensive treatment say for example a residential stay in long-term drug rehabilitation program. If a person is involved with substance abuse and needs help, they are able to use their Medicaid health coverage to obtain this help. If they don't have Medicaid and in addition don't have the funds or some other kind of medical insurance to pay for rehab, they could find out if they qualify for Medicaid and then sign up for an alcohol and drug treatment facility which is approved inside their state.
