Medicaid is a type of health care insurance available for many people who are in specific income brackets which qualifies them to receive this government funded insurance. Whether someone qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they earn an acceptable income. For instance, people who have many dependents may be entitled to Medicaid regardless of whether they earn what can be described as a fair income. Medicaid may also cover the expense of rehab, if a person has been abusing drugs or alcohol and requires treatment. There are many alcohol and drug rehab facilities which accept Medicaid, but various states have distinct guidelines for what forms of treatment are covered. Certain states only cover outpatient treatment services for example while other states cover far more extensive treatment such as a residential stay in long-term alcohol and drug rehabilitation center. If somebody is involved with substance abuse and desires help, they're able to use their Medicaid insurance coverage to get this help. If they don't have Medicaid plus don't have the funds or any other form of medical insurance to cover rehab, they could check if they qualify for Medicaid and then enroll in a drug rehab facility which is approved inside their state.
