Medicaid is a health insurance available for those who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether a person is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they earn a fair income. For example, people who have a lot of dependents may be eligible for Medicaid even when they make what might certainly be a reasonable income. Medicaid can also cover the expense of treatment, if a person has been abusing alcohol or drugs and requires rehab. There are many drug and alcohol treatment centers which accept Medicaid, but different states have distinct rules for what kinds of rehabilitation are covered. Some states only include outpatient rehabilitation services by way of example while other states cover more extensive rehab say for example a residential stay in long-term alcohol and drug rehab program. If someone is involved with drug abuse and desires help, they can use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid and in addition don't have the cash or any other type of medical insurance to pay for rehab, they can see if they are eligible for a Medicaid and then enroll in a drug and alcohol treatment center which is approved inside their state.
