Medicaid is a form of medical health insurance available for many people who are in certain income brackets which qualifies them to obtain this government funded 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 just because they make an acceptable income. For instance, individuals who have many dependents may be entitled to Medicaid regardless of whether they earn what can be described as a sensible income. Medicaid also can cover the costs of rehabilitation, when someone has been abusing drugs or alcohol and requires treatment. There are many drug and alcohol rehab facilities which accept Medicaid, but various states have distinct rules for what types of treatment are covered. Certain states only include outpatient treatment services for instance while other states cover more extensive rehab say for example a residential stay in long-term drug and alcohol rehab facility. If someone is involved with substance abuse and needs help, they can use their Medicaid health coverage to get this help. If they don't have Medicaid and in addition don't have the money or another type of medical insurance to cover rehabilitation, they can see if they are eligible for a Medicaid and then sign up for a drug and alcohol rehabilitation program that's approved inside their state.
