Medicaid is a form of health insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether somebody qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify just because they make a fair income. By way of example, people who have many dependents may qualify for Medicaid regardless of whether they make what would be considered a reasonable income. Medicaid can also cover the expense of treatment, if a person has been abusing drugs or alcohol and needs rehab. There are numerous drug and alcohol treatment programs which accept Medicaid, but different states have different guidelines for what types of rehabilitation are covered. Certain states only cover outpatient rehab services as an example while other states cover more extensive rehabilitation like a residential stay in long-term alcohol and drug rehab program. If anyone is involved with drug use and needs help, they could use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid and also don't have the money or another form of medical insurance to cover treatment, they can check if they are eligible for a Medicaid and then enroll in a drug and alcohol rehabilitation center that's approved within their state.
