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. Electronic remittance advice (ERA/835) files — IMPORTANT UPDATE:

    AmeriHealth Caritas (DC) is pleased to Inform you that a solution has been developed in collaboration with Change Healthcare/Optum to provide the detailed payment recovery information missing from the provider remittance advice. This solution will provide payment recovery details on the remittance advice or 835 you receive with your payments for claims processed on and after May 6, 2024.

    For claims processed February 21, 2024 through May 5, 2024, AmeriHealth Caritas DC has generated a comprehensive claims recovery report available in the NaviNet provider portal. For more details for accessing this report see the Remittance Advice Payment Recovery Details Now Available! (PDF) provider notice.

    Providers can view and download an electronic remittance pdf via the NaviNet provider portal. Providers may also access the ERA/835 file through ECHO Health. For additional information, please see the 835 Access (PDF) provider notice.

  2. 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.

  3. 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 District of Columbia to Availity.

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

  4. Submitting claims through Change Healthcare – Although AmeriHealth Caritas DC has not reconnected directly to Change Healthcare, providers may submit claims to AmeriHealth Caritas DC through Change Healthcare.

    • Providers may use Relay Health or iEDI (the two clearing houses being offered today by Change Healthcare/Optum) for submitting claims to AmeriHealth Caritas DC. 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.
      • If you do not know who your account representative is, you can submit an inquiry via the Change Healthcare General Inquiry form.

  5. Manual claims submission through PCH Global: To enroll for claims submission  through PCH Global, please go to and click the Sign-Up link in the upper right-hand corner to register.
