Medicaid is a type of health care insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance. Whether or not a person qualifies for Medicaid doesn't only depend upon their earnings however, and individuals shouldn't assume they don't qualify simply because they earn a fair income. For instance, people who have quite a few dependents may qualify for Medicaid even if they make what would certainly be a reasonable income. Medicaid could also cover the costs of treatment, when someone has been abusing drugs or alcohol and needs rehab. There are lots of drug treatment programs which accept Medicaid, but various states have different rules for what forms of rehabilitation are covered. Certain states only include outpatient rehabilitation services for instance while other states cover far more intensive rehabilitation say for example a residential stay in long-term drug and alcohol treatment center. If anyone is involved with drug use and desires help, they can use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid and in addition don't have enough cash or another type of health insurance to cover rehab, they could check if they are eligible for a Medicaid and then enroll in an alcohol and drug rehab facility that's approved in their state.
