Medicaid is a form of medical health insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance. Whether or not a person is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify just because they earn an acceptable income. For instance, people who have many dependents may be entitled to Medicaid regardless of whether they make what might be described as a fair income. Medicaid also can cover the expenses of rehabilitation, if someone has been abusing drugs or alcohol and requires treatment. There are lots of drug rehab centers which accept Medicaid, but various states have distinct guidelines for what forms of treatment are covered. Some states only cover outpatient treatment services as an example while other states cover far more extensive rehabilitation like a residential stay in long-term drug rehab program. If somebody is involved in drug use and desires help, they could use their Medicaid health coverage to obtain this help. If they don't have Medicaid and in addition don't have the money or any other type of medical health insurance to cover rehabilitation, they can see if they qualify for Medicaid and then sign up for a drug treatment facility which is approved in their state.
