Know Your Provider Network
A provider network is a list of the doctors, other health care providers, and hospitals your health insurer or plan has attached to it. The prescription drugs covered can vary from plan to plan. Members often receive the most coverage at the lowest cost when they use a provider in their network.
Your plan's provider network likely will be shown on your health insurance card: HMO (health maintenance organization) or PMO (preferred provider organization) for example.
