Medicaid can also cover the expense of rehab, if someone has been abusing drugs or alcohol and requires treatment. There are lots of drug and alcohol rehab facilities which accept Medicaid, but different states have distinct rules for what sorts of rehab are covered. Some states only cover outpatient rehab services as an example while other states cover far more extensive rehab like a residential stay in long-term drug and alcohol treatment program.
