Medicaid is a kind of medical insurance available for those who are in specific income brackets which qualifies them to acquire this government provided insurance coverage. Whether or not someone is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify just because they make an acceptable income. As an example, men and women who have many dependents may qualify for Medicaid even if they earn an amount be described as a fair income. Medicaid may also cover the expense of rehab, if a person has been abusing alcohol or drugs and needs rehabilitation. There are many drug and alcohol rehab programs which accept Medicaid, but different states have different rules for what forms of treatment are covered. Some states only cover outpatient treatment services for instance while other states cover far more intensive treatment say for example a residential stay in long-term drug rehab facility. If someone is involved with substance abuse and needs help, they are able to use their Medicaid health coverage to get this treatment. If they don't have Medicaid and in addition don't have the funds or another kind of health care insurance to pay for rehab, they can determine if they are eligible for a Medicaid and then sign up for a drug treatment program which is approved within their state.
