Medicaid is a form of medical insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether a person qualifies for Medicaid doesn't only determined by their earnings however, and people shouldn't assume they don't qualify simply because they earn an acceptable income. As an example, people who have quite a few dependents may qualify for Medicaid even though they make what might be described as a fair income. Medicaid could also cover the costs of rehabilitation, if someone has been abusing alcohol or drugs and requires treatment. There are numerous alcohol and drug rehab centers which accept Medicaid, but different states have different guidelines for what forms of treatment are covered. Some states only include outpatient treatment services for example while other states cover more intensive treatment say for example a residential stay in long-term drug and alcohol rehab facility. If a person is involved with substance abuse and wants help, they can use their Medicaid insurance coverage to get this help. If they don't have Medicaid plus don't have enough cash or another type of health insurance to cover rehab, they can find out if they qualify for Medicaid and then enroll in a drug and alcohol rehab program that's approved inside their state.
