Medicaid is a form of medical insurance available for many people who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only depend on their earnings however, and individuals shouldn't presume they don't qualify because they make a reasonable income. For example, men and women who have many dependents may be eligible for Medicaid even if they make what can be described as a fair income. Medicaid may also cover the expenses of treatment, if someone has been abusing drugs or alcohol and needs treatment. There are lots of alcohol and drug rehab centers which accept Medicaid, but different states have distinct rules for what kinds of rehab are covered. Some states only include outpatient treatment services by way of example while other states cover more extensive treatment say for example a residential stay in long-term alcohol and drug rehab program. If a person is involved in drug use and wants help, they can use their Medicaid insurance coverage to get this help. If they don't have Medicaid plus don't have enough cash or some other form of medical insurance to pay for rehab, they could see if they qualify for Medicaid and then sign up for a drug rehab center which is approved inside their state.
