Does Candor Health measure network adequacy?
No. Network adequacy measurement and the filings that go to CMS and state regulators are what Quest Analytics does. Candor Health keeps the provider records underneath that analysis accurate, which decides whether the adequacy result is real.
The plain answer
Adequacy tools count the providers, and Candor Health makes sure the providers being counted are real
An adequacy report is only as good as the records it measures. That is where the two jobs connect.

01
What is network adequacy measurement, and who does it?
Quest Analytics: QESNetwork adequacy is whether a plan's network has enough providers of each type within the time and distance standards regulators set. Quest Analytics has measured and filed it for health plans since 2003. Quest says it works with 90% of payers and 30+ state regulators, and its QES platform covers network compliance, data integrity and performance. Quest also owns BetterDoctor, a provider attestation portal.

What does Candor Health do?
Candor Health: verified company informationCandor Health builds each provider record from 120,000+ sources and 4 billion+ claims a month, scores every field and republishes daily. Network Builder turns provider search results into saved networks, shows where the gaps are and finds the providers that close them. That helps you build a network. It is not a regulatory adequacy filing.

03
Why does the data decide the adequacy result?
CMS Online Provider Directory Review Report, Round 3Adequacy counts providers at locations. If the provider has moved, retired or stopped taking patients, the count is wrong and the network is a ghost network on paper. CMS found at least one inaccuracy at 48.74% of the directory locations it reviewed. Fix the data first and the adequacy measure means something.
