Overview
In alignment with Executive Order 14222, the Centers for Medicare & Medicaid Services (CMS) has announced the decommissioning of the CSSC Operations website, effective May 31, 2025.
All resources related to Risk Adjustment and Prescription Drug Event (PDE) data submission currently hosted on the CSSC platform will be migrated to CMS.gov in the coming months.
This initiative is part of a federal effort to streamline digital services, improve information access, and reduce operational redundancies across government agencies.
Key Transition Details
Decommission Date: May 31, 2025
Impacted Content:
Risk Adjustment technical documentation
Encounter data submission tools
PDE file specifications
Submission guidance and training materials
New Destination:
CMS.gov (specific sections for Risk Adjustment and PDE will host the migrated materials)
Rationale Behind the Change
This transition is driven by Executive Order 14222, titled “Implementing the President’s ‘Department of Government Efficiency’ Cost Efficiency Initiative”. The order emphasizes optimizing federal systems by reducing duplication and consolidating information platforms.
By hosting all Medicare data submission content on CMS.gov, CMS aims to create a centralized, authoritative source for plans and data submitters—thereby enhancing usability, security, and consistency.
Continued Support Availability
While the website itself will be sunset, the CSSC Operations Help Desk will remain fully operational to support all Risk Adjustment and PDE submission inquiries.
Stakeholders may continue to contact CSSC through the following channels:
Email: csscoperations@palmettogba.com
Phone: 1-877-534-2772
This ensures continuity of service throughout and beyond the transition period.
Recommended Actions for Stakeholders
To ensure a smooth transition, stakeholders are encouraged to take the following steps:
Bookmark CMS.gov and familiarize teams with relevant navigation paths
Download and archive any critical documents from the CSSC website prior to decommission
Update internal SOPs and documentation with the new CMS.gov links (once released)
Notify impacted teams, including IT, compliance, analytics, and vendor partners
Monitor CMS.gov communications for updated timelines and resource availability
Where to Find Migrated Content
Once migrated, stakeholders can expect to find Risk Adjustment and PDE documentation within the following CMS.gov sections:
CMS Risk Adjustment Resources
CMS Prescription Drug Event (PDE) Information
CMS will announce specific navigation paths and provide updates as the migration progresses.
Final Notes
The decommissioning of the CSSC Operations website represents a strategic shift toward centralization and digital modernization across federal systems. While change of this scale can present initial operational adjustments, CMS is committed to ensuring an orderly and transparent transition.
Stakeholders are encouraged to act early, stay informed, and utilize continued support from CSSC Operations to maintain submission compliance and data integrity throughout the migration.
If your organization requires transition planning assistance, documentation templates, or internal training resources, we recommend initiating those preparations now to avoid disruptions.
For further updates, please monitor communications from CMS and bookmark the CMS.gov portals relevant to your role.
