Medicaid is a type of medical insurance available for individuals who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether or not an individual qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify because they make a reasonable income. For example, people who have many dependents may be entitled to Medicaid regardless of whether they make what might be described as a fair income. Medicaid may also cover the expenses of rehabilitation, when someone has been abusing drugs or alcohol and requires treatment. There are many alcohol and drug rehabilitation facilities which accept Medicaid, but different states have distinct guidelines for what forms of treatment are covered. Some states only include outpatient treatment services for example while other states cover far more extensive rehab like a residential stay in long-term drug rehab program. If somebody is involved in drug abuse and wants help, they can use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid and also don't have the money or another type of medical insurance to cover treatment, they could find out if they qualify for Medicaid and then enroll in a drug and alcohol rehabilitation facility that's approved in their state.
