Medicaid is a form of health insurance available for those who are in certain income brackets which qualifies them to acquire this government provided insurance coverage. Whether or not an individual is qualified for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify because they earn a fair income. As an example, people who have quite a few dependents may be entitled to Medicaid even when they earn what can be described as a sensible income. Medicaid can also cover the costs of treatment, when someone has been abusing alcohol or drugs and requires rehab. There are lots of alcohol and drug rehabilitation facilities which accept Medicaid, but various states have different guidelines for what kinds of treatment are covered. Certain states only cover outpatient rehab services by way of example while other states cover more intensive rehab say for example a residential stay in long-term drug rehab center. If somebody is involved in substance abuse and wants help, they could use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid and in addition don't have enough cash or any other type of health insurance to cover rehabilitation, they could see if they are eligible for a Medicaid and then sign up for an alcohol and drug treatment facility that is approved in their state.
