Medicaid is a form of health care insurance available for individuals who are in specific income brackets which qualifies them to receive this government provided insurance coverage. Whether or not someone is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify simply because they make a reasonable income. As an example, individuals who have a lot of dependents may qualify for Medicaid even when they earn what might be described as a sensible income. Medicaid may also cover the costs of rehabilitation, if someone has been abusing alcohol or drugs and requires rehabilitation. There are lots of drug and alcohol rehabilitation facilities which accept Medicaid, but different states have distinct rules for what kinds of treatment are covered. Some states only cover outpatient treatment services for instance while other states cover more extensive rehab such as a residential stay in long-term alcohol and drug rehab center. If anyone is involved with substance abuse and wants help, they are able to use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid and in addition don't have enough cash or any other form of medical insurance to cover rehabilitation, they can see if they are eligible for a Medicaid and then sign up for a drug treatment facility that is approved inside their state.
