Medicaid is a form of medical health insurance available for individuals who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether someone qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify just because they earn a reasonable income. For example, people who have many dependents may be entitled to Medicaid even when they make what can be described as a sensible income. Medicaid also can cover the expenses of rehab, if someone has been abusing drugs or alcohol and requires treatment. There are numerous drug rehabilitation centers which accept Medicaid, but various states have different guidelines for what forms of rehabilitation are covered. Certain states only include outpatient rehabilitation services by way of example while other states cover more extensive treatment like a residential stay in long-term drug rehab center. If anyone is involved in substance abuse and wants help, they are able to use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid and also don't have the funds or any other form of medical insurance to pay for treatment, they can determine if they are eligible for a Medicaid and then enroll in an alcohol and drug rehab program that is approved within their state.
