Medicaid is a health insurance available for individuals who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether someone is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify simply because they make an acceptable income. For example, individuals who have many dependents may be entitled to Medicaid even when they earn what would certainly be a sensible income. Medicaid could also cover the expenses of rehab, if a person has been abusing drugs or alcohol and requires treatment. There are many drug and alcohol rehabilitation facilities which accept Medicaid, but various states have different rules for what kinds of rehab are covered. Certain states only include outpatient rehab services for example while other states cover more intensive treatment such as a residential stay in long-term alcohol and drug treatment center. If somebody is involved with drug use and needs help, they're able to use their Medicaid health coverage to get this help. If they do not have Medicaid plus don't have the funds or any other kind of medical insurance to pay for rehab, they can determine if they are eligible for a Medicaid and then sign up for a drug rehab program that is approved inside their state.
