Medicaid is a kind of medical insurance available for individuals who are in specific income brackets which qualifies them to acquire this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify because they make an acceptable income. For example, people who have many dependents may be entitled to Medicaid regardless of whether they earn what might be described as a fair income. Medicaid may also cover the expenses of rehabilitation, if a person has been abusing drugs or alcohol and requires treatment. There are many drug rehabilitation facilities which accept Medicaid, but various states have distinct rules for what forms of treatment are covered. Certain states only include outpatient treatment services as an example while other states cover more extensive rehab such as a residential stay in long-term drug rehab program. If somebody is involved with drug abuse and desires help, they could use their Medicaid health coverage to get this treatment. If they don't have Medicaid and in addition don't have the funds or some other form of medical insurance to cover rehab, they could see if they are eligible for a Medicaid and then enroll in an alcohol and drug rehab facility which is approved in their state.
