Sectigo has recently updated its root and intermediate certificates, including the introduction of the new Sectigo Root R46. To avoid potential service disruption, please ensure your TrustStores are updated with the latest certificates as soon as possible.
As certificate authorities are rotating their roots more frequently, Optum recommends keeping your TrustStores current as part of regular maintenance.

Customers,
As part of Optum’s effort to continuously improve our systems, we are migrating to Cloudflare to enhance system redundancy, security and cost effectiveness.
This will affect both the network (switch) and e-Prescribing, specifically the following URLs:
• connect.changehealthcare.com
• rxnsconnect.changehealthcare.com
• scriptrouting.changehealthcare.com
• connecthttppost.changehealthcare.com
As part of this change, the DNS names will resolve to the IP Subnet 168.183.3.128 /27 (usable range 168.183.3.128 - 168.183.3.159).
If your firewall filters by DNS, then no action should be needed on your part.
However, if your organization does IP filtering, you will need to add to your whitelist for outbound traffic to IP Subnet 168.183.3.128 /27 (usable range 168.183.3.128-168.183.3.159). This should be completed by March 1, 2026 to avoid disruption when the change is implemented.
