Medicaid is a kind of medical insurance available for individuals who are in specific income brackets which qualifies them to obtain this government funded insurance. Whether a person is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify just because they earn an acceptable income. By way of example, individuals who have a lot of dependents may be entitled to Medicaid even though they earn what might be considered a reasonable income. Medicaid may also cover the costs of treatment, when someone has been abusing alcohol or drugs and needs rehabilitation. There are many drug and alcohol rehab programs which accept Medicaid, but various states have distinct rules for what types of treatment are covered. Certain states only include outpatient treatment services for instance while other states cover more extensive treatment such as a residential stay in long-term drug and alcohol treatment facility. If someone is involved in substance abuse and needs help, they could use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid plus don't have enough cash or another type of medical insurance to cover rehabilitation, they could see if they are eligible for a Medicaid and then sign up for a drug treatment facility which is approved within their state.
