Top IDNs by Physician Group membership

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.
