Know the plan's network and select it when you search, and make sure the provider you want to visit is in that network.
Knowing your network can save you money.
Note that providers may move in and out of a network and that a hospital or clinic may use both in-network and out-of-network providers. To make sure your provider is in your network, check before each visit. The best way to verify participation is to sign in before using Find a doctor.
