Medicaid is a form of health insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether or not an individual qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify because they earn 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 treatment, if someone has been abusing drugs or alcohol and requires treatment. There are lots of drug and alcohol rehab centers which accept Medicaid, but different states have different rules for what kinds of rehabilitation are covered. Certain states only include outpatient rehab services by way of example while other states cover far more intensive rehab say for example a residential stay in long-term alcohol and drug rehab program. If somebody is involved with substance abuse and wants help, they can use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid plus don't have the funds or another kind of medical insurance to pay for rehab, they could find out if they are eligible for a Medicaid and then enroll in a drug rehab facility that's approved in their state.
