Yes, there are three of them. They are:
In case of an emergency like a stroke or cardiac arrest, you can check in to the nearest emergency room. The EPO plan will cover the cost of emergency care even if the hospital is not in the network.
You can arrange for an out-of-network specialist with the insurer after prior intimation if your EPO plan does not have a specialist providing a particular healthcare facility.
If you purchased your EPO insurance plan while undergoing a complex treatment in out-of-network care, the plan will cover the treatment cost with the current doctor on a case-by-case basis.
