Medicaid is a form of health care insurance available for many people who are in specific income brackets which qualifies them to receive this government provided insurance. Whether an individual is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't presume they don't qualify because they make a reasonable income. By way of example, individuals who have a lot of dependents may be entitled to Medicaid regardless of whether they make what would be considered a fair income. Medicaid may also cover the expense of rehab, when someone has been abusing alcohol or drugs and requires rehabilitation. There are many alcohol and drug treatment programs which accept Medicaid, but different states have different guidelines for what kinds of treatment are covered. Certain states only include outpatient rehab services for instance while other states cover far more intensive treatment such as a residential stay in long-term drug and alcohol treatment facility. If someone is involved with substance abuse and wants help, they could use their Medicaid health coverage to get this help. If they don't have Medicaid plus don't have the cash or some other type of medical insurance to pay for rehabilitation, they could see if they are eligible for a Medicaid and then enroll in a drug and alcohol rehab center that's approved within their state.
