Medicaid is a kind of medical health insurance available for individuals who are in specific income brackets which qualifies them to acquire this government funded insurance coverage. Whether an individual is qualified for Medicaid doesn't only depend on their earnings however, and individuals shouldn't assume they don't qualify because they earn a fair income. For example, people who have many dependents may be entitled to Medicaid even when they make what can be described as a reasonable income. Medicaid could also cover the price of rehab, if a person has been abusing drugs or alcohol and requires rehabilitation. There are lots of drug rehab centers which accept Medicaid, but various states have different rules for what types of rehabilitation are covered. Some states only include outpatient rehab services for instance while other states cover far more extensive rehab say for example a residential stay in long-term drug rehabilitation program. If someone is involved with drug use and wants help, they could use their Medicaid health coverage to get this treatment. If they do not have Medicaid plus don't have the money or some other type of health insurance to cover rehab, they could see if they are eligible for a Medicaid and then sign up for a drug treatment program which is approved inside their state.
