Medicaid is a form of health insurance available for those who are in specific income brackets which qualifies them to receive this government provided insurance coverage. Whether or not an individual is qualified for Medicaid doesn't only depend on their earnings however, and individuals shouldn't assume they don't qualify just because they earn a fair income. As an example, individuals who have a lot of dependents may qualify for Medicaid even when they earn what would be considered a fair income. Medicaid could also cover the costs of rehab, when someone has been abusing alcohol or drugs and requires rehab. There are many alcohol and drug rehab programs which accept Medicaid, but various states have distinct guidelines for what kinds of rehabilitation are covered. Some states only include outpatient treatment services as an example while other states cover more intensive treatment like a residential stay in long-term alcohol and drug rehabilitation facility. If a person is involved with drug abuse and desires help, they could use their Medicaid health coverage to obtain this help. If they don't have Medicaid and in addition don't have the cash or some other kind of health care insurance to pay for rehab, they could determine if they are eligible for a Medicaid and then sign up for an alcohol and drug treatment center which is approved within their state.
