The following list highlights the top Integrated Delivery Networks (IDNs) by number of affiliated physician groups. A physician group is constituted by one or more physicians operating as an organization to deliver care. In order for an organization to be placed under a network, Definitive Healthcare requires that the IDN have ownership or operational control over the group.
With 42 affiliated physician groups, Wills-Knighton Health System—a Louisiana-based IDN—has the greatest number of reported in-network physician groups. The states appearing the most frequently as IDN headquarters were Pennsylvania and Tennessee, each with five networks represented. Due to numerous ties, the top 23 IDNs are represented in the list below.
