Medicaid is a form of health care insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether an individual qualifies for Medicaid doesn't only determined by income however, and people shouldn't presume they don't qualify just because they make an acceptable income. For example, individuals who have quite a few dependents may be entitled to Medicaid even though they make what might be described as a reasonable income. Medicaid may also cover the costs of treatment, if a person has been abusing alcohol or drugs and requires rehab. There are lots of drug rehabilitation programs which accept Medicaid, but different states have different guidelines for what forms of rehabilitation are covered. Some states only cover outpatient treatment services for instance while other states cover far more intensive rehab like a residential stay in long-term drug rehab program. If somebody is involved with drug abuse and wants help, they can use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid plus don't have the money or some other form of health insurance to pay for rehabilitation, they can find out if they are eligible for a Medicaid and then enroll in an alcohol and drug rehabilitation program which is approved inside their state.
