Medicaid is a type of health care insurance available for individuals who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether a person is qualified for Medicaid doesn't only depend upon their earnings however, and individuals shouldn't assume they don't qualify because they earn a good income. As an example, people who have many dependents may be entitled to Medicaid even when they earn what might be described as a reasonable income. Medicaid may also cover the price of rehab, if someone has been abusing drugs or alcohol and requires rehab. There are numerous drug rehab programs which accept Medicaid, but various states have different guidelines for what types of rehabilitation are covered. Some states only cover outpatient treatment services for instance while other states cover more extensive rehab such as a residential stay in long-term alcohol and drug rehabilitation program. If someone is involved in drug abuse and needs help, they're able to use their Medicaid insurance coverage to obtain this treatment. If they do not have Medicaid plus don't have the money or another type of medical health insurance to cover rehab, they could check if they are eligible for a Medicaid and then enroll in a drug treatment facility that's approved within their state.
