National PPO
This map indicates the concentration of medical providers throughout the United states.

The geographic diversity of the network allows a greater level of penetration than with virtually any other network available in the marketplace. ECHA clients, even national in scope, can achieve as high as 90% of claims being re-priced through a negotiated fee arrangement. This broad penetration generally assures an initial cost reduction and long term cost stabilization of benefit plans.
