Medicaid is a health insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether someone is qualified for Medicaid doesn't only determined by their earnings however, and people shouldn't assume they don't qualify simply because they earn an acceptable income. As an example, people who have many dependents may be entitled to Medicaid even when they earn what would be considered a sensible income. Medicaid also can cover the price of treatment, if a person has been abusing alcohol or drugs and needs rehab. There are lots of drug and alcohol treatment centers which accept Medicaid, but various states have different guidelines for what forms of rehabilitation are covered. Some states only cover outpatient rehabilitation services by way of example while other states cover more extensive rehab like a residential stay in long-term drug and alcohol rehabilitation facility. If somebody is involved in drug abuse and needs help, they are able to use their Medicaid health coverage to get this help. If they don't have Medicaid and in addition don't have enough cash or another form of health care insurance to pay for rehabilitation, they can find out if they qualify for Medicaid and then enroll in a drug and alcohol treatment program that is approved within their state.
