Medicaid is a kind of medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether a person qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify because they earn an acceptable income. For example, people who have many dependents may be entitled to Medicaid even when they make what can be considered a reasonable income. Medicaid also can cover the costs of rehab, if someone has been abusing alcohol or drugs and needs rehabilitation. There are lots of drug and alcohol rehab facilities which accept Medicaid, but different states have different rules for what forms of treatment are covered. Certain states only cover outpatient rehabilitation services by way of example while other states cover far more extensive treatment say for example a residential stay in long-term alcohol and drug rehab program. If a person is involved in drug use and wants help, they can use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and also don't have enough cash or any other kind of medical health insurance to cover rehab, they can check if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation program which is approved in their state.
