Medicaid is a kind of medical insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance. Whether a person is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify just because they make a reasonable income. By way of example, individuals who have many dependents may be eligible for Medicaid even when they make what can be described as a sensible income. Medicaid also can cover the costs of treatment, when someone has been abusing drugs or alcohol and requires rehab. There are lots of drug rehab programs which accept Medicaid, but different states have different rules for what types of treatment are covered. Certain states only cover outpatient rehab services for example while other states cover far more extensive rehab like a residential stay in long-term drug and alcohol treatment facility. If a person is involved with drug use and desires help, they could use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid and also don't have the cash or another kind of health care insurance to pay for treatment, they could check if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation program that's approved within their state.
