Medicaid is a type of health insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether an individual qualifies for Medicaid doesn't only depend on their earnings however, and individuals shouldn't presume they don't qualify just because they make a good income. For example, people who have a lot of dependents may be eligible for Medicaid regardless of whether they make an amount be considered a reasonable income. Medicaid can also cover the expense of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are lots of drug and alcohol rehab centers which accept Medicaid, but various states have distinct rules for what types of treatment are covered. Some states only cover outpatient rehabilitation services for example while other states cover far more intensive treatment say for example a residential stay in long-term drug and alcohol rehabilitation program. If a person is involved with drug use and desires help, they could use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and in addition don't have enough cash or another kind of medical health insurance to pay for rehabilitation, they can find out if they are eligible for a Medicaid and then sign up for a drug and alcohol rehab program that's approved within their state.
