Medicaid is a type of health care insurance available for those who are in specific income brackets which qualifies them to acquire this government provided insurance. Whether someone qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify because they earn a good income. As an example, individuals who have a lot of dependents may be eligible for Medicaid even when they earn what would be described as a sensible income. Medicaid may also cover the expenses of treatment, when someone has been abusing alcohol or drugs and requires rehabilitation. There are lots of drug and alcohol rehab facilities which accept Medicaid, but different states have different rules for what types of rehab are covered. Certain states only cover outpatient rehab services for instance while other states cover more intensive rehab such as a residential stay in long-term drug and alcohol treatment program. If anyone is involved with drug use and needs help, they could use their Medicaid health coverage to obtain this help. If they do not have Medicaid and also don't have the funds or another type of health care insurance to pay for treatment, they can check if they are eligible for a Medicaid and then enroll in a drug and alcohol treatment facility that is approved inside their state.
