Medicaid is a type of medical insurance available for those who are in specific income brackets which qualifies them to obtain this government funded insurance coverage. Whether or not somebody qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify just because they make an acceptable income. For instance, men and women who have a lot of dependents may be entitled to Medicaid even if they make what can be described as a sensible income. Medicaid can also cover the costs of rehabilitation, when someone has been abusing drugs or alcohol and requires rehab. There are several drug rehabilitation programs which accept Medicaid, but various states have distinct rules for what types of rehabilitation are covered. Certain states only cover outpatient treatment services as an example while other states cover more intensive treatment like a residential stay in long-term drug rehabilitation facility. If anyone is involved with substance abuse and needs help, they can use their Medicaid insurance coverage to get this help. If they don't have Medicaid and in addition don't have the funds or some other kind of health care insurance to cover treatment, they can find out if they qualify for Medicaid and then enroll in a drug treatment program that is approved inside their state.
