Medicaid is a kind of health care insurance available for many people who are in certain income brackets which qualifies them to receive this government funded insurance. Whether someone qualifies for Medicaid doesn't only depend upon their earnings however, and individuals shouldn't assume they don't qualify just because they earn a reasonable income. As an example, men and women who have a lot of dependents may be entitled to Medicaid even when they earn what can be described as a sensible income. Medicaid may also cover the costs of rehab, if a person has been abusing drugs or alcohol and requires treatment. There are many drug and alcohol rehab programs which accept Medicaid, but various states have different rules for what types of rehabilitation are covered. Some states only cover outpatient rehabilitation services for instance while other states cover more extensive rehabilitation like a residential stay in long-term alcohol and drug rehabilitation program. If anyone is involved in substance abuse and needs help, they are able to use their Medicaid insurance coverage to get this help. If they do not have Medicaid plus don't have the cash or another kind of health care insurance to pay for rehab, they could find out if they are eligible for a Medicaid and then enroll in a drug treatment center that's approved within their state.
