Medicaid is a health insurance available for those who are in specific income brackets which qualifies them to acquire this government funded insurance coverage. Whether or not a person is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify simply because they earn a good income. As an example, people who have quite a few dependents may be eligible for Medicaid even though they make what would be considered a fair income. Medicaid may also cover the costs of treatment, when someone has been abusing alcohol or drugs and requires rehab. There are numerous drug and alcohol treatment programs which accept Medicaid, but various states have distinct guidelines for what sorts of rehab are covered. Some states only include outpatient rehab 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 with substance abuse and desires help, they can use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and also don't have the cash or another kind of health care insurance to pay for treatment, they could check if they qualify for Medicaid and then sign up for a drug and alcohol rehab program that's approved in their state.
