Medicaid is a health care insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether somebody qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify simply because they make a good income. For instance, individuals who have many dependents may be entitled to Medicaid even though they make what would be described as a sensible income. Medicaid also can cover the costs of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are several alcohol and drug rehab centers which accept Medicaid, but various states have different rules for what sorts of treatment are covered. Certain states only include outpatient rehabilitation services as an example while other states cover far more extensive rehabilitation say for example a residential stay in long-term alcohol and drug rehabilitation program. If someone is involved in substance abuse and needs help, they can use their Medicaid health coverage to obtain this help. If they do not have Medicaid and also don't have the cash or another form of medical health insurance to pay for treatment, they could check if they are eligible for a Medicaid and then sign up for a drug treatment program which is approved within their state.
