Prior authorization means that your doctor must get approval from Blue Shield before prescribing specific medications or performing a particular medical service or operation. Without this prior approval, Blue Shield may not pay for your medication or medical procedure, and you will have to pay out of pocket.

To see if a particular service or drug requires prior authorization, open the Blue Shield and FEP Prior authorization list PDF below. If your entry is on the list, then you will need to work with your doctor to get prior authorization before Blue Shield will pay.

Remember, it’s always important to check that the service or drug you need is a covered benefit under your plan. For any questions about prior authorization, please call Customer Service at the number on the back of your Blue Shield member ID card.
