In order to minimize disruption for potential new clients, a dental plan needs to maximize its overlap with competitors' networks. In other words, they need to have as many of the same dentists as possible. What might be a manageable task when aiming to match up with a single competitor, this gets quite challenging for a plan with 8-10 significant competitors.
In the chart above, the blue circle represents Network A, a middle-of-the-pack network among the Top 15 dental PPO plans, while the gold circle represents the average of all of the Top 15 dental PPO plans. Network A, though quite large, only overlaps with its peers at a rate of 57%. This means that while 6 out of 10 access points in Network A's network are likely also to be in any given competitor's network, 4 out of 10 are not, and will potentially cause disruption for a prospective client. The challenge for Network A, as it is for all dental plans looking to grow, is to maximize their overlap with key competitors so that potential clients will experience minimal disruption when switching to their plan.
