Network size is measured in many different ways. Some dental carriers count unique licenses, some count provider locations, while others count access points. And, unfortunately, some dental insurance companies may not keep their records up-to-date, failing to remove retired or no longer practicing dentists from their lists of participating dentists. These differences can artificially inflate a network’s size, making it appear much larger than it truly is.
What’s the Difference: Licenses vs. Locations vs. Access Points
Unique licenses refers to the total number of individual dental licenses. Every dentist is assigned a unique license number and the dentist’s unique license is not impacted by the number of offices in which a dentist works. This indicator represents individual dentists and is the most accurate indicator of network size.
Unique provider locations is a helpful but secondary indicator of network size. Dentists who practice in multiple locations bring their expertise to a broader geographic area, but with limited availability at each location. This indicator allows a dentist to be counted multiple times (once for each practice they work at). Since the dentist splits time between those practices, it is not the best representation of access and network size.
Access points, perhaps the most confusing indicator of network size, are arrived at by multiplying the number of unique dentists by the locations in which they practice. For example, 4 dentists practicing in 5 office locations equals 20 access points. These “access points” are not necessarily indicative of practical access as an enrollee could still only see one unique dentist at one office location at one point in time.
What Does This Mean To You And Your Clients?
An artificially inflated network is a hassle for you and your clients—just imagine the phone calls you may receive when your clients run into problems receiving services from in-network dentists. To ensure that you’re receiving an accurate representation of a network’s true size, it’s important to understand how a dental carrier quantifies their networks.
Tip #1: The size of the network cannot exceed the number of dentist licenses.
The Arizona Dental Board of Examiners (BODEX) oversees dentist licensing within the state and posts licensing data on its homepage. As of June 30, 2018, the Board had 4,854 licensed dentists on file. If a dental carrier claims to have a network with more than 4,854 Arizona dentists, this is your first clue the carrier may be inflating its numbers.
Tip #2: The number of practicing dentists within Arizona is lower than the number of licensed dentists.
While BODEX issues dental licenses, it relies on the dentists to self-report when they retire or move out of state. To understand the true number of licensed, practicing dentists within the state, you must remove licensed dentists with an out-of-state address from your network count, as these dentists are not practicing in Arizona. Unfortunately, this information isn’t readily available to the public, but according to our monthly reports, about 800 of the licensed dentists on file with BODEX do not practice in Arizona. This puts the actual number of licensed, practicing dentists in Arizona at 4,054. If a dental carrier claims to have a network with more dentists, this is a sign the carrier may be inflating its numbers.
Tip #3: Ask each dental carrier for the number of unique providers in its network.
To ensure an apples to apples comparison, you need each carrier to use the same network measurement. Unique provider count (aka unique licenses) is the most accurate indicator of the network size, and the indicator upon which Delta Dental relies the most to measure our networks.
