Credentialing Overview

HCAS implemented a centralized and streamlined provider credentialing process as its first initiative. This process offers a single point-of-entry for providers to submit credentialing information that HCAS participating health plans use to verify a provider’s qualifications prior to network participation. Each health plan makes independent decisions regarding a provider’s eligibility for participation in its network.

HCAS is committed to achieving significant efficiencies in the credentialing process by building on the success of a statewide physician credentialing initiative in Massachusetts. HCAS extended its centralized credentialing process to include physicians and allied health providers working in several New England states.

Process Components

HCAS participating health plans partner with CAQH® to collect and store a provider’s credentialing information. Information is collected one time from providers, reducing the need to submit multiple applications to different sources.

A provider’s credentialing data is then utilized to complete the primary source verification process. Verisys, formerly Aperture Health, a national credentials verification organization (CVO), performs the primary source verification function on behalf of HCAS participating health plans.


Health plans are required by law and by accrediting organizations to credential providers on a periodic basis. Due to these requirements, there are significant efficiencies to be gained by centralizing the process. The most significant of which is that it enables providers to complete the application process one time for several health plans. In addition, when a provider completes the recredentialing process every few years existing data can be updated, reducing the amount of time that providers spend on administrative work.
