Medicaid is a form of medical insurance available for many people who are in specific income brackets which qualifies them to receive this government funded insurance coverage. Whether somebody is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify simply because they make a reasonable income. By way of example, people who have a lot of dependents may be eligible for Medicaid even though they make what might be described as a fair income. Medicaid can also cover the costs of rehab, when someone has been abusing alcohol or drugs and requires rehab. There are lots of drug and alcohol treatment centers which accept Medicaid, but different states have different guidelines for what forms of rehabilitation are covered. Some states only include outpatient treatment services by way of example while other states cover more intensive rehabilitation say for example a residential stay in long-term alcohol and drug rehab facility. If a person is involved with drug abuse and wants help, they are able to use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid and also don't have the money or some other type of health care insurance to pay for rehab, they can check if they are eligible for a Medicaid and then sign up for a drug rehab center which is approved in their state.
