Medicaid is a type of medical health insurance available for many people who are in specific income brackets which qualifies them to receive this government funded insurance. Whether or not someone qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify because they earn a fair income. For instance, people who have many dependents may be eligible for Medicaid even when they make what might be described as a reasonable income. Medicaid also can cover the costs of treatment, when someone has been abusing alcohol or drugs and requires rehab. There are lots of alcohol and drug treatment programs which accept Medicaid, but different states have distinct guidelines for what sorts of rehabilitation are covered. Some states only cover outpatient rehabilitation services as an example while other states cover more intensive rehab like a residential stay in long-term alcohol and drug treatment center. If somebody is involved in substance abuse and wants help, they are able to use their Medicaid health coverage to get this treatment. If they don't have Medicaid and also don't have enough cash or another kind of medical health insurance to cover rehab, they can determine if they are eligible for a Medicaid and then sign up for a drug and alcohol treatment center which is approved within their state.
