Medicaid is a form of health care insurance available for many people who are in certain income brackets which qualifies them to acquire this government provided insurance. Whether someone qualifies for Medicaid doesn't only determined by income however, and people shouldn't presume they don't qualify because they earn a reasonable income. As an example, men and women who have many dependents may be eligible for Medicaid even if they make what can be considered a fair income. Medicaid can also cover the costs of treatment, if a person has been abusing alcohol or drugs and requires treatment. There are many drug and alcohol rehab facilities which accept Medicaid, but various states have different guidelines for what forms of treatment are covered. Some states only cover outpatient rehabilitation services by way of example while other states cover far more extensive rehabilitation say for example a residential stay in long-term alcohol and drug rehab program. If someone is involved in drug abuse and needs help, they can use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid and also don't have the cash or any other type of medical health insurance to cover rehab, they could determine if they are eligible for a Medicaid and then sign up for a drug rehabilitation facility that's approved inside their state.
