Medicaid is a health care insurance available for individuals who are in specific income brackets which qualifies them to acquire this government provided insurance. Whether somebody qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify because they make a reasonable income. As an example, people who have many dependents may qualify for Medicaid even though they make what might be considered a fair income. Medicaid also can cover the price of treatment, when someone has been abusing alcohol or drugs and requires rehabilitation. There are numerous alcohol and drug rehabilitation programs which accept Medicaid, but different states have different rules for what sorts of treatment are covered. Some states only include outpatient treatment services as an example while other states cover more extensive treatment like a residential stay in long-term drug and alcohol treatment center. If somebody is involved with drug use and needs help, they can use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid and in addition don't have the cash or another form of medical insurance to pay for rehab, they can determine if they are eligible for a Medicaid and then enroll in a drug and alcohol treatment facility that is approved in their state.
