Medicaid is a health insurance available for many people who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether or not somebody qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify just because they make an acceptable income. As an example, individuals who have quite a few dependents may qualify for Medicaid even though they make what can be described as a reasonable income. Medicaid also can cover the price of treatment, if a person has been abusing drugs or alcohol and requires rehabilitation. There are many alcohol and drug rehabilitation programs which accept Medicaid, but different states have distinct guidelines for what forms of rehabilitation are covered. Certain states only cover outpatient treatment services for example while other states cover more intensive rehab like a residential stay in long-term drug rehab program. If someone is involved in drug abuse and desires help, they are able to use their Medicaid insurance coverage to obtain this treatment. If they do not have Medicaid and in addition don't have the money or any other kind of health care insurance to pay for rehab, they could find out if they are eligible for a Medicaid and then enroll in a drug treatment center which is approved within their state.
