Medicaid is a health insurance available for individuals 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 simply because they earn a fair income. For instance, men and women who have many dependents may be entitled to Medicaid even if they earn what might be considered a fair income. Medicaid also can cover the expenses of rehabilitation, if someone has been abusing alcohol or drugs and needs treatment. There are lots of drug and alcohol rehab programs which accept Medicaid, but different states have distinct rules for what forms of rehabilitation are covered. Certain states only cover outpatient treatment services for example while other states cover far more extensive treatment like a residential stay in long-term alcohol and drug treatment program. If anyone is involved in drug use and needs help, they could use their Medicaid health coverage to get this treatment. If they don't have Medicaid plus don't have the cash or some other type of medical health insurance to pay for rehab, they could determine if they qualify for Medicaid and then sign up for a drug rehabilitation center that is approved in their state.
