Medicaid is a form of health care insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether someone qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't assume they don't qualify because they make a fair income. For example, individuals who have many dependents may qualify for Medicaid even though they make an amount certainly be a reasonable income. Medicaid can also cover the expense of rehab, if someone has been abusing alcohol or drugs and requires rehab. There are lots of drug rehabilitation programs which accept Medicaid, but different states have different rules for what forms of treatment are covered. Some states only include outpatient treatment services for example while other states cover far more intensive treatment such as a residential stay in long-term alcohol and drug rehabilitation center. If someone is involved in drug abuse and needs help, they are able to use their Medicaid health coverage to acquire this help. If they do not have Medicaid and also don't have enough cash or any other form of health care insurance to pay for treatment, they can see if they are eligible for a Medicaid and then enroll in a drug and alcohol rehab facility which is approved in their state.
