CareSource requires you to get prior authorization for certain drugs. This means that you will need to get approval from CareSource before the prescription is filled. If you don’t get approval, CareSource may not cover the drug.

In some cases, CareSource requires you to first try certain drugs to treat a medical condition before we will cover another drug for that condition. For example, if Drug A and Drug B both treat the medical condition, CareSource may not cover Drug B unless you try Drug A first. If Drug A does not work for you, CareSource will then cover Drug B.
