Medicaid is a form of medical insurance available for those who are in specific income brackets which qualifies them to receive this government funded insurance coverage. Whether or not someone qualifies for Medicaid doesn't only depend on income however, and individuals shouldn't presume they don't qualify simply because they make a fair income. As an example, people who have quite a few dependents may be eligible for Medicaid even if they earn what might be considered a fair income. Medicaid may also cover the expenses of rehabilitation, when someone has been abusing drugs or alcohol and needs rehabilitation. There are lots of drug and alcohol treatment programs which accept Medicaid, but various states have distinct guidelines for what kinds of treatment are covered. Certain states only include outpatient rehab services as an example while other states cover more extensive treatment say for example a residential stay in long-term drug treatment facility. If somebody is involved in substance abuse and desires help, they could use their Medicaid health coverage to acquire this help. If they don't have Medicaid and in addition don't have the cash or any other type of health insurance to cover rehabilitation, they can check if they are eligible for a Medicaid and then sign up for a drug rehabilitation facility that's approved inside their state.
