Medicaid is a medical insurance available for many people who are in certain income brackets which qualifies them to acquire this government funded insurance coverage. Whether someone is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify because they earn a good income. By way of example, people who have a lot of dependents may qualify for Medicaid even when they make what would be described as a reasonable income. Medicaid can also cover the expenses of rehab, if a person has been abusing alcohol or drugs and needs rehabilitation. There are lots of drug treatment facilities which accept Medicaid, but different states have distinct rules for what forms of rehabilitation are covered. Certain states only cover outpatient rehabilitation services as an example while other states cover far more extensive rehabilitation say for example a residential stay in long-term drug and alcohol rehabilitation center. If somebody is involved in drug abuse and needs help, they are able to use their Medicaid health coverage to acquire this help. If they do not have Medicaid plus don't have the funds or another kind of health insurance to cover treatment, they could see if they qualify for Medicaid and then sign up for a drug rehab program that is approved within their state.
