Medicaid is a kind of health care insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance coverage. Whether or not an individual qualifies for Medicaid doesn't only determined by income however, and people shouldn't presume they don't qualify because they make a fair income. For instance, people who have many dependents may qualify for Medicaid even when they make what can be described as a fair income. Medicaid can also cover the costs of rehabilitation, if someone has been abusing drugs or alcohol and requires treatment. There are lots of alcohol and drug rehab centers which accept Medicaid, but different states have different rules for what kinds of rehab are covered. Certain states only cover outpatient treatment services as an example while other states cover more extensive treatment say for example a residential stay in long-term alcohol and drug rehabilitation facility. If someone is involved with substance abuse and desires help, they are able to use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid and also don't have the funds or another type of health insurance to pay for rehab, they can check if they qualify for Medicaid and then enroll in an alcohol and drug rehab program that is approved within their state.
