Medicaid is a health care insurance available for those who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify simply because they earn an acceptable income. For example, people who have many dependents may qualify for Medicaid even though they make what might certainly be a reasonable income. Medicaid could also cover the expense of rehabilitation, when someone has been abusing alcohol or drugs and needs treatment. There are several drug rehab centers which accept Medicaid, but different states have distinct rules for what forms of treatment are covered. Some states only cover outpatient treatment services as an example while other states cover far more extensive rehab such as a residential stay in long-term drug and alcohol rehabilitation program. If a person is involved with substance abuse and desires help, they can use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and also don't have the cash or any other form of health care insurance to pay for rehabilitation, they could see if they qualify for Medicaid and then enroll in a drug and alcohol treatment facility that's approved inside their state.
