Medicaid is a kind of health care insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether a person is qualified for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify because they make an acceptable income. By way of example, people who have many dependents may qualify for Medicaid even when they earn what can be considered a sensible income. Medicaid can also cover the costs of rehab, when someone has been abusing alcohol or drugs and needs rehabilitation. There are several drug and alcohol rehabilitation programs which accept Medicaid, but various states have distinct rules for what kinds of treatment are covered. Some states only cover outpatient rehab services by way of example while other states cover far more extensive rehabilitation such as a residential stay in long-term drug and alcohol rehabilitation facility. If someone is involved with drug abuse and needs help, they could use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid and also don't have the money or any other kind of medical insurance to cover rehabilitation, they can see if they are eligible for a Medicaid and then sign up for a drug treatment facility that is approved inside their state.
