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 an individual is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they earn a fair income. For instance, individuals who have many dependents may qualify for Medicaid even if they earn what would certainly be a fair income. Medicaid may also cover the expense of rehabilitation, if someone has been abusing alcohol or drugs and requires rehabilitation. There are lots of drug and alcohol rehab facilities which accept Medicaid, but various states have different rules for what types of treatment are covered. Certain states only include outpatient treatment services for example while other states cover far more extensive treatment say for example a residential stay in long-term drug rehab center. If someone is involved in substance abuse and desires help, they are able to use their Medicaid health coverage to get this help. If they do not have Medicaid and in addition don't have the cash or another form of medical insurance to pay for rehab, they can see if they qualify for Medicaid and then sign up for a drug and alcohol rehab facility that's approved in their state.
