Medicaid is a form of medical health insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not somebody is qualified for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify just because they earn a reasonable income. For example, people who have quite a few dependents may be eligible for Medicaid regardless of whether they make an amount be considered a sensible income. Medicaid also can cover the expense of rehab, if someone has been abusing alcohol or drugs and requires treatment. There are many drug rehabilitation centers which accept Medicaid, but different states have distinct rules for what forms of rehab are covered. Some states only include outpatient treatment services for instance while other states cover far more extensive treatment such as a residential stay in long-term drug and alcohol rehabilitation facility. If someone is involved with drug abuse and wants help, they could use their Medicaid health coverage to get this treatment. If they do not have Medicaid and also don't have the cash or some other type of medical health insurance to pay for treatment, they could find out if they are eligible for a Medicaid and then sign up for an alcohol and drug treatment program that is approved inside their state.
