If your prescribing doctor feels it is necessary to exceed the set limit, he or she must get prior approval before the higher quantity will be covered.
Prior Authorization: Certain Drugs require you or your doctor to get prior authorization in order to be covered. Usually just an additional form. If you dont get approval, the plan may not cover the drug.
Step Therapy: Means you must first try one drug to treat your medical condition before the plan will cover another drug for the same condition. If you have already tried other drugs or your doctor thinks they are not right for you, you and your doctor can ask the plan to cover this drug.
Avg Unit Cost: Average unit cost (e.g. per pill) for specified days supply at in-area retail pharmacies. A pharmacy is considered in-area when it is geographically located in the service area.

What if a drug I need is not listed?

Please check the formulary for different brand and generic names. If you still cannot locate your drugs, your plan may not offer coverage. Talk to your doctor first about changing your prescription to a drug on your plans formulary. If this is not an option, you can request an exception to have the plan review its coverage decision based on your individual circumstances.
