Medicaid is a type of health care insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't assume they don't qualify because they make a reasonable income. For example, people who have a lot of dependents may be entitled to Medicaid even when they make what can certainly be a reasonable income. Medicaid also can cover the costs of treatment, if someone has been abusing alcohol or drugs and requires rehab. There are many drug and alcohol treatment facilities which accept Medicaid, but various states have distinct rules for what sorts of rehab are covered. Some states only cover outpatient rehabilitation services by way of example while other states cover far more extensive treatment such as a residential stay in long-term alcohol and drug rehab program. If a person is involved with drug abuse and wants help, they could use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid and in addition don't have the cash or some other kind of medical insurance to cover rehabilitation, they could find out if they qualify for Medicaid and then enroll in an alcohol and drug rehab program which is approved in their state.
