Medicaid is a health care insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether or not an individual is qualified for Medicaid doesn't only depend on their earnings however, and individuals shouldn't assume they don't qualify simply because they earn a reasonable income. As an example, individuals who have a lot of dependents may be entitled to Medicaid even though they earn what might be considered a fair income. Medicaid could also cover the costs of treatment, when someone has been abusing drugs or alcohol and requires treatment. There are lots of alcohol and drug treatment centers which accept Medicaid, but various states have distinct guidelines for what kinds of treatment are covered. Some states only include outpatient rehabilitation services for example while other states cover far more intensive treatment such as a residential stay in long-term alcohol and drug rehabilitation program. If someone is involved in drug abuse and needs help, they could use their Medicaid health coverage to obtain this help. If they do not have Medicaid plus don't have the cash or any other type of health care insurance to cover treatment, they can find out if they qualify for Medicaid and then enroll in a drug rehab facility which is approved inside their state.
