Medicaid is a health insurance available for many people who are in specific income brackets which qualifies them to acquire this government funded insurance. Whether or not someone qualifies for Medicaid doesn't only depend on income however, and individuals shouldn't presume they don't qualify just because they earn an acceptable income. For example, individuals who have quite a few dependents may be entitled to Medicaid even though they earn what might be described as a fair income. Medicaid could also cover the price of rehab, if a person has been abusing alcohol or drugs and requires rehabilitation. There are many drug and alcohol rehabilitation programs which accept Medicaid, but different states have distinct rules for what types of rehabilitation are covered. Some states only include outpatient rehabilitation services as an example while other states cover more extensive rehab say for example a residential stay in long-term alcohol and drug rehab facility. If somebody is involved with drug abuse and needs help, they are able to use their Medicaid health coverage to get this treatment. If they don't have Medicaid and also don't have the funds or some other form of medical insurance to cover treatment, they can find out if they qualify for Medicaid and then sign up for an alcohol and drug treatment program that's approved in their state.
