Medicaid is a form of medical health insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance. Whether a person is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify because they make a good income. For instance, people who have a lot of dependents may be eligible for Medicaid even if they make what might be considered a fair income. Medicaid could also cover the price of rehabilitation, when someone has been abusing drugs or alcohol and requires treatment. There are lots of drug and alcohol rehabilitation facilities which accept Medicaid, but various states have different guidelines for what forms of rehabilitation are covered. Certain states only cover outpatient rehabilitation services for example while other states cover far more extensive treatment say for example a residential stay in long-term drug rehab facility. If anyone is involved with drug abuse and needs help, they could use their Medicaid health coverage to get this treatment. If they do not have Medicaid plus don't have the cash or some other type of health care insurance to cover rehab, they could find out if they are eligible for a Medicaid and then sign up for an alcohol and drug rehab center that's approved in their state.
