Medicaid is a medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not somebody qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify just because they make an acceptable income. By way of example, people who have a lot of dependents may qualify for Medicaid even though they earn what might be considered a fair income. Medicaid may also cover the costs of rehab, when someone has been abusing alcohol or drugs and requires rehab. There are numerous drug rehab facilities which accept Medicaid, but different states have different guidelines for what kinds of treatment are covered. Certain states only include outpatient treatment services as an example while other states cover more extensive rehabilitation say for example a residential stay in long-term drug rehab center. If someone is involved in substance abuse and wants help, they could use their Medicaid health coverage to get this help. If they don't have Medicaid plus don't have the money or some other type of health insurance to pay for treatment, they can find out if they are eligible for a Medicaid and then enroll in a drug and alcohol rehab center that's approved within their state.
