Change Healthcare System Interruption

Change Healthcare, our electronic data interchange (EDI) clearinghouse for claims and payment cycle management, continues to address their network interruption related to a security incident. Below are updates for our systems and processes:

  1. Claims payments: Providers who were unable to successfully submit claims during the outage may now submit them either through Availity or PCH Global, or, through Change Healthcare once connectivity is restored. We have extended the claims timely filing deadline for claims that would have been rejected due to untimely filing during the service interruption. For more details, see the Claims Timely Filing Deadline Extension (PDF) provider notice.

  2. Electronic claims submission through Availity: If you or your clearinghouse do not currently use Availity to submit claims, you must register with Availity at: Please choose the registration option that aligns with your business: Healthcare or Atypical Provider.

    For registration process assistance and other resources, access the training site link on the Availity registration page.

    If you are currently registered with Availity for another payor, or if you use another clearinghouse, you must request that they route your electronic claims for AmeriHealth Caritas New Hampshire to Availity.

    For additional information and resources see the recent Additional Information for Availity (PDF) provider notice.

  3. Submitting claims through Change Healthcare – Although AmeriHealth Caritas New Hampshire has not reconnected directly to Change Healthcare, providers may submit claims to AmeriHealth Caritas New Hampshire through Change Healthcare.

    • Providers may use Relay Health or iEDI (the two clearinghouses being offered today by Change Healthcare/Optum) for submitting claims to AmeriHealth Caritas New Hampshire. Claims submitted through these clearinghouses will be routed to us via Availity until we reestablish direct connectivity to Change Healthcare.
      • To use Relay Health or iEDI, you will have to establish new connectivity with these clearinghouses.
      • For new connectivity requirements, you will need to reach out to your Change Healthcare account representative.
