Medicaid is a health care insurance available for those who are in specific income brackets which qualifies them to receive this government provided insurance. Whether a person qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they make a good income. As an example, people who have many dependents may qualify for Medicaid even if they make what would certainly be a sensible income. Medicaid may also cover the price of rehabilitation, if someone has been abusing alcohol or drugs and requires rehabilitation. There are several drug and alcohol treatment facilities which accept Medicaid, but various states have different rules for what kinds of treatment are covered. Certain states only include outpatient rehab services for example while other states cover more extensive rehab such as a residential stay in long-term drug and alcohol rehabilitation facility. If someone is involved in substance abuse and wants help, they're able to use their Medicaid insurance coverage to get this help. If they do not have Medicaid plus don't have the cash or some other form of health insurance to cover rehab, they can check if they are eligible for a Medicaid and then enroll in a drug treatment center that's approved inside their state.
