Medicaid is a form of medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify because they make an acceptable income. For instance, people who have many dependents may be eligible for Medicaid even if they make an amount be described as a reasonable income. Medicaid could also cover the price of rehab, if someone has been abusing drugs or alcohol and requires treatment. There are lots of drug and alcohol rehabilitation facilities which accept Medicaid, but different states have distinct rules for what types of treatment are covered. Certain states only include outpatient treatment services for instance while other states cover far more intensive rehabilitation say for example a residential stay in long-term drug and alcohol rehabilitation program. If somebody is involved with substance abuse and wants help, they're able to use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid plus don't have the money or some other type of medical health insurance to cover rehabilitation, they can determine if they qualify for Medicaid and then sign up for a drug rehab program which is approved in their state.
