Medicaid is a medical insurance available for those who are in specific income brackets which qualifies them to obtain this government funded insurance.

For instance, people who have quite a few dependents may qualify for Medicaid even when they make an amount be considered a fair income. Medicaid can also cover the price of rehab, when someone has been abusing alcohol or drugs and requires rehabilitation. There are several alcohol and drug rehabilitation facilities which accept Medicaid, but various states have distinct guidelines for what kinds of rehabilitation are covered. Some states only cover outpatient treatment services for instance while other states cover far more extensive rehab like a residential stay in long-term drug and alcohol treatment program. If anyone is involved with drug use and needs help, they can use their Medicaid health coverage to obtain this help. If they don't have Medicaid plus don't have the funds or another type of medical health insurance to pay for rehab, they can find out if they are eligible for a Medicaid and then sign up for a drug and alcohol rehabilitation program that's approved within their state.
