Medicaid is a kind of medical health insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether someone qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they make a good income. For instance, individuals who have a lot of dependents may be eligible for Medicaid even when they make what might be considered a sensible income. Medicaid may also cover the expense of treatment, when someone has been abusing alcohol or drugs and needs treatment. There are several drug rehab centers which accept Medicaid, but various states have different guidelines for what sorts of treatment are covered. Certain states only include outpatient rehabilitation services as an example while other states cover far more extensive rehab like a residential stay in long-term drug rehab facility. If anyone is involved in substance abuse and needs help, they could use their Medicaid health coverage to obtain this help. If they don't have Medicaid and also don't have the money or another kind of medical health insurance to cover rehab, they can see if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation program that is approved in their state.
