Medicaid is a kind of health care insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether somebody is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify because they earn a reasonable income. As an example, people who have many dependents may be entitled to Medicaid even though they earn what can be described as a reasonable income. Medicaid could also cover the expenses of rehabilitation, when someone has been abusing drugs or alcohol and requires treatment. There are lots of alcohol and drug rehabilitation programs which accept Medicaid, but various states have distinct guidelines for what types of treatment are covered. Some states only cover outpatient treatment services for example while other states cover more extensive rehabilitation say for example a residential stay in long-term drug and alcohol rehab center. If a person is involved with substance abuse and wants help, they could use their Medicaid insurance coverage to get this help. If they don't have Medicaid and also don't have enough cash or another form of medical insurance to cover rehabilitation, they could check if they qualify for Medicaid and then sign up for a drug rehabilitation program which is approved in their state.
