Medicaid is a form of medical insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether an individual is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify simply because they make a good income. For instance, people who have many dependents may be entitled to Medicaid regardless of whether they earn an amount be described as a reasonable income. Medicaid could also cover the expenses of rehabilitation, if someone has been abusing alcohol or drugs and requires rehabilitation. There are many alcohol and drug rehab programs which accept Medicaid, but various states have different rules for what sorts of rehabilitation are covered. Some states only include outpatient rehab services for example while other states cover more intensive rehab like a residential stay in long-term drug treatment facility. If someone is involved with drug abuse and wants help, they can use their Medicaid health coverage to get this help. If they don't have Medicaid and in addition don't have the money or some other form of health care insurance to pay for rehabilitation, they could see if they qualify for Medicaid and then sign up for a drug treatment facility which is approved within their state.
