Medicaid is a form of medical insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance coverage. Whether or not someone qualifies for Medicaid doesn't only determined by their earnings however, and individuals shouldn't assume they don't qualify simply because they make a fair income. By way of example, individuals who have many dependents may qualify for Medicaid even when they make what would be considered a reasonable income. Medicaid could also cover the expenses of rehab, if someone has been abusing drugs or alcohol and requires rehabilitation. There are several drug rehab programs which accept Medicaid, but different states have distinct rules for what sorts of rehabilitation are covered. Some states only cover outpatient treatment services as an example while other states cover more intensive treatment say for example a residential stay in long-term drug and alcohol rehabilitation facility. If somebody is involved in substance abuse and needs help, they could use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid and also don't have the cash or some other type of medical insurance to pay for rehab, they can see if they are eligible for a Medicaid and then sign up for a drug and alcohol treatment program that's approved in their state.
