Medicaid is a health care insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether a person qualifies for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify just because they earn a good income. As an example, men and women who have a lot of dependents may qualify for Medicaid even when they earn an amount be considered a reasonable income. Medicaid may also cover the expense of rehabilitation, if a person has been abusing alcohol or drugs and requires treatment. There are several alcohol and drug treatment programs which accept Medicaid, but various states have different guidelines for what sorts of rehabilitation are covered. Some states only cover outpatient rehabilitation services by way of example while other states cover more extensive rehabilitation such as a residential stay in long-term alcohol and drug rehabilitation facility. If someone is involved in drug abuse and wants help, they can use their Medicaid health coverage to get this help. If they don't have Medicaid and in addition don't have the money or some other kind of health care insurance to pay for rehabilitation, they can determine if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation facility which is approved within their state.
