Medicaid is a type of medical insurance available for those who are in specific income brackets which qualifies them to receive this government provided insurance coverage. Whether a person is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify simply because they earn a good income. As an example, people who have a lot of dependents may be entitled to Medicaid even if they earn what would certainly be a fair income. Medicaid also can cover the costs of rehabilitation, when someone has been abusing alcohol or drugs and requires treatment. There are several drug rehab facilities which accept Medicaid, but different states have distinct rules for what types of treatment are covered. Some states only cover outpatient rehabilitation services for example while other states cover far more intensive rehab such as a residential stay in long-term alcohol and drug rehabilitation program. If somebody is involved with drug abuse and needs help, they're able to use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and in addition don't have enough cash or some other kind of health insurance to cover rehab, they can see if they qualify for Medicaid and then enroll in a drug and alcohol rehab facility that is approved within their state.
