Medicaid is a medical insurance available for many people who are in specific income brackets which qualifies them to receive this government provided insurance. Whether an individual qualifies for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify just because they make a good income. As an example, people who have a lot of dependents may be eligible for Medicaid regardless of whether they earn what would be described as a reasonable income. Medicaid could also cover the costs of rehabilitation, if a person has been abusing alcohol or drugs and needs rehabilitation. There are numerous drug rehabilitation programs which accept Medicaid, but various states have distinct guidelines for what types of treatment are covered. Some states only include outpatient treatment services for example while other states cover far more intensive rehab such as a residential stay in long-term drug rehab center. If anyone is involved in substance abuse and needs help, they can use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid and also don't have the money or some other form of medical health insurance to pay for rehabilitation, they could determine if they qualify for Medicaid and then sign up for a drug and alcohol treatment facility that's approved in their state.
