Provider networks are a foundational part of how health insurance plans control costs and manage access to care. A provider network is a group of doctors, hospitals, pharmacies, and other healthcare providers that have contracted with an insurance company to deliver services at negotiated rates.
Understanding provider networks helps individuals predict healthcare costs, avoid surprise bills, and choose plans that align with their preferred doctors and hospitals. Network rules affect referrals, out-of-pocket costs, emergency coverage, and whether care is covered at all.
This guide explains how provider networks work, why they exist, and how different network structures affect access to healthcare services.
