Medicaid is a form of medical insurance available for those who are in certain income brackets which qualifies them to acquire this government provided insurance coverage. Whether or not a person qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify simply because they make a fair income. As an example, individuals who have many dependents may qualify for Medicaid even though they make what might be described as a reasonable income. Medicaid also can cover the expenses of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are many drug rehab facilities which accept Medicaid, but various states have distinct rules for what kinds of treatment are covered. Certain states only include outpatient treatment services as an example while other states cover more extensive rehabilitation say for example a residential stay in long-term drug and alcohol rehabilitation center. If a person is involved in substance abuse and needs help, they could use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid plus don't have the money or some other form of health insurance to pay for rehabilitation, they can see if they are eligible for a Medicaid and then sign up for an alcohol and drug rehab program which is approved in their state.
