Medicaid is a health insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance coverage. Whether or not someone is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify because they make a good income. For example, men and women who have quite a few dependents may be eligible for Medicaid even though they earn what can certainly be a sensible income. Medicaid may also cover the costs of rehab, if someone has been abusing alcohol or drugs and requires rehab. There are lots of drug rehab facilities which accept Medicaid, but different states have different rules for what kinds of rehabilitation are covered. Certain states only include outpatient treatment services for example while other states cover more intensive rehab like a residential stay in long-term drug rehabilitation center. If a person is involved in drug use and desires help, they are able to use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid and in addition don't have the funds or some other type of medical insurance to cover rehabilitation, they can find out if they are eligible for a Medicaid and then enroll in a drug rehabilitation program that's approved inside their state.
