Medicaid is a type of medical insurance available for those who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not someone qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify just because they earn a fair income. For instance, men and women who have many dependents may be entitled to Medicaid even though they earn what would certainly be a sensible income. Medicaid could also cover the expense of treatment, when someone has been abusing alcohol or drugs and needs treatment. There are many alcohol and drug rehab facilities which accept Medicaid, but various states have distinct guidelines for what forms of rehab are covered. Certain states only cover outpatient rehab services for example while other states cover far more intensive treatment like a residential stay in long-term alcohol and drug treatment program. If someone is involved with substance abuse and desires help, they are able to use their Medicaid health coverage to get this treatment. If they don't have Medicaid plus don't have the funds or some other form of medical health insurance to pay for rehabilitation, they could find out if they qualify for Medicaid and then sign up for a drug treatment program which is approved within their state.
