Medicaid is a form of medical insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance coverage. Whether or not someone qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't presume they don't qualify just because they make a fair income. As an example, individuals who have many dependents may qualify for Medicaid even if they make what can be considered a reasonable income. Medicaid could also cover the expenses of rehabilitation, if a person has been abusing alcohol or drugs and needs treatment. There are lots of alcohol and drug treatment programs which accept Medicaid, but various states have different rules for what kinds of rehab are covered. Certain states only include outpatient rehab services for example while other states cover more extensive rehab such as a residential stay in long-term alcohol and drug treatment center. If anyone is involved in drug use and desires help, they are able to use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and also don't have the cash or any other type of medical health insurance to cover rehabilitation, they can check if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation facility which is approved in their state.
