For example, if you are traveling Out of Area (OOA) and skiing in Colorado, and you have a medical emergency, emergency room care is considered In-Network. Any financial responsibility you have under your health plan (coinsurance, copay) should be calculated as part of In-Network.
* If you have an HMO or EPO plan, it is black and white language. If you have a PPO plan, legally it is a bit squishy because of the already provided for out of network (OON) access. BUT - generally - any emergency is considered in network no matter what product you have and where you are.
