Medicaid is a type of medical insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether an individual is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they earn an acceptable income. For example, individuals who have a lot of dependents may be eligible for Medicaid even if they earn what might be described as a fair income. Medicaid could also cover the price of treatment, when someone has been abusing drugs or alcohol and requires treatment. There are several alcohol and drug rehabilitation programs which accept Medicaid, but different states have different rules for what kinds of treatment are covered. Certain states only cover outpatient rehabilitation services for example while other states cover more extensive rehabilitation like a residential stay in long-term drug and alcohol rehabilitation facility. If somebody is involved in drug abuse and wants help, they're able to use their Medicaid health coverage to acquire this help. If they do not have Medicaid and also don't have the funds or another type of medical health insurance to cover rehab, they can determine if they qualify for Medicaid and then sign up for a drug treatment program that is approved within their state.
