Medicaid is a medical health insurance available for those who are in specific income brackets which qualifies them to obtain this government funded insurance coverage. Whether or not a person is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify simply because they make a good income. For instance, people who have many dependents may be eligible for Medicaid even if they earn what might be considered a sensible income. Medicaid can also cover the costs of treatment, if someone has been abusing alcohol or drugs and requires rehabilitation. There are several alcohol and drug rehab facilities which accept Medicaid, but different states have different rules for what types of rehab are covered. Certain states only cover outpatient rehabilitation services for example while other states cover more extensive treatment like a residential stay in long-term drug and alcohol treatment center. If anyone is involved in drug use and desires help, they're able to use their Medicaid insurance coverage to obtain this help. If they do not have Medicaid plus don't have the money or any other type of health care insurance to pay for rehab, they could see if they qualify for Medicaid and then sign up for a drug rehab facility that's approved within their state.
