Medicaid is a type of health care insurance available for those who are in specific income brackets which qualifies them to receive this government provided insurance. Whether or not an individual qualifies for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify because they make a good income. By way of example, people who have many dependents may be eligible for Medicaid even if they make what might be considered a fair income. Medicaid may also cover the costs of treatment, if someone has been abusing alcohol or drugs and requires rehab. There are numerous drug rehabilitation centers which accept Medicaid, but various states have distinct rules for what types of rehab are covered. Certain states only cover outpatient rehabilitation services by way of example while other states cover far more extensive treatment like a residential stay in long-term drug and alcohol rehab center. If someone is involved in substance abuse and needs help, they could use their Medicaid health coverage to obtain this help. If they do not have Medicaid and also don't have the money or another kind of medical health insurance to pay for rehabilitation, they can find out if they are eligible for a Medicaid and then sign up for an alcohol and drug rehab center that is approved within their state.
