Medicaid is a kind of medical insurance available for individuals who are in specific income brackets which qualifies them to acquire this government provided insurance coverage. Whether an individual is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify because they earn a reasonable income. For instance, individuals who have a lot of dependents may be eligible for Medicaid regardless of whether they make what can be considered a reasonable income. Medicaid also can cover the expenses of rehab, if a person has been abusing drugs or alcohol and requires rehab. There are lots of drug rehabilitation facilities which accept Medicaid, but various states have distinct rules for what kinds of treatment are covered. Some states only cover outpatient treatment services for instance while other states cover far more intensive treatment say for example a residential stay in long-term drug and alcohol rehabilitation center. If somebody is involved in substance abuse and needs help, they can use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid and in addition don't have enough cash or some other form of medical insurance to pay for rehab, they can see if they qualify for Medicaid and then sign up for a drug and alcohol rehab center that is approved inside their state.
