Medicaid is a medical health insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance. Whether or not somebody is qualified for Medicaid doesn't only determined by their earnings however, and people shouldn't presume they don't qualify simply because they make an acceptable income. By way of example, people who have many dependents may be eligible for Medicaid even though they earn what might be considered a sensible income. Medicaid can also cover the expenses of rehab, if a person has been abusing alcohol or drugs and needs rehabilitation. There are several drug and alcohol treatment programs which accept Medicaid, but various states have different rules for what forms of treatment are covered. Some states only cover outpatient rehab services as an example while other states cover more extensive treatment say for example a residential stay in long-term alcohol and drug rehabilitation facility. If someone is involved with substance abuse and needs help, they can use their Medicaid health coverage to get this help. If they do not have Medicaid and in addition don't have the money or another type of health care insurance to cover treatment, they could determine if they are eligible for a Medicaid and then enroll in a drug and alcohol rehabilitation facility which is approved within their state.
