Medicaid is a form of medical insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify because they make a reasonable income. As an example, people who have many dependents may qualify for Medicaid even if they make what would be described as a fair income. Medicaid could also cover the expenses of rehabilitation, when someone has been abusing alcohol or drugs and requires treatment. There are several drug and alcohol treatment programs which accept Medicaid, but different states have different rules for what sorts of rehabilitation are covered. Some states only include outpatient treatment services by way of example while other states cover more intensive rehab say for example a residential stay in long-term alcohol and drug rehabilitation program. If a person is involved in substance abuse and wants help, they are able to use their Medicaid health coverage to get this treatment. If they don't have Medicaid plus don't have enough cash or another type of health care insurance to pay for rehabilitation, they could find out if they are eligible for a Medicaid and then enroll in a drug treatment facility which is approved inside their state.
