Medicaid is a health care insurance available for many people who are in certain income brackets which qualifies them to acquire this government provided insurance. Whether a person is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify simply because they earn a good income. For instance, people who have many dependents may be entitled to Medicaid even though they make what can certainly be a reasonable income. Medicaid may also cover the expenses of rehabilitation, if someone has been abusing alcohol or drugs and requires rehabilitation. There are several drug and alcohol treatment centers which accept Medicaid, but different states have different rules for what kinds of rehabilitation are covered. Certain states only include outpatient rehabilitation services for example while other states cover far more intensive rehab such as a residential stay in long-term alcohol and drug rehabilitation facility. If somebody is involved with substance abuse and desires help, they could use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid plus don't have the cash or some other form of medical health insurance to cover rehab, they can determine if they qualify for Medicaid and then sign up for a drug and alcohol treatment center which is approved inside their state.
