We work with almost all major insurance companies, but there are a few exceptions. Our team works hard to get our clients credentialed as fast and accurately as we can, but not all insurance companies allow us to meet these goals. Because of this, after many years of frustration and unpredictable service quality, we are no longer offering any credentialing services for Aetna. This was a difficult decision, but ultimately we are confident that this choice will allow us to put our time and energy to better use for all our clients.
