Medicaid is a medical health insurance available for many people who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether or not an individual is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify just because they earn a reasonable income. For example, people who have many dependents may be eligible for Medicaid even when they make what would be considered a reasonable income. Medicaid could also cover the expenses of treatment, when someone has been abusing drugs or alcohol and requires rehabilitation. There are numerous alcohol and drug treatment centers which accept Medicaid, but different states have distinct rules for what forms of rehabilitation are covered. Some states only include outpatient rehabilitation services for example while other states cover more intensive rehab such as a residential stay in long-term drug and alcohol rehabilitation program. If somebody is involved in drug use and wants help, they could use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid plus don't have the money or any other kind of medical health insurance to pay for treatment, they could see if they are eligible for a Medicaid and then sign up for a drug rehabilitation center that's approved inside their state.
