CMS recently announced that it will postpone the planned decommissioning of the CSSC Operations website, which was originally scheduled to occur on May 31, 2025. This site, csscoperations.com, plays an important role in Medicare Advantage and Part D operations, especially when it comes to Risk Adjustment and Prescription Drug Event (PDE) data submission.

The decision to delay comes as CMS works to ramp up its Risk Adjustment Data Validation (RADV) audits. The agency recognizes that the CSSC website provides essential tools and information that many health plans and system vendors rely on for timely and accurate data submission. Disrupting access during such a critical compliance period could negatively impact reporting, so CMS is hitting pause — for now.

So what does this mean for you? It means nothing changes just yet. Health plans can continue to access everything they need through csscoperations.com, including file layouts, submission guidance, and technical documentation. The site remains the central hub for encounter data and PDE submissions until further notice.

CMS hasn’t shared a new date for the transition to CMS.gov, but they’ve confirmed that more information will be provided in a future memo. Until then, you can keep using the same processes and tools you’re already familiar with.

Support also remains in place. The CSSC Operations Help Desk is still available to answer your questions related to data submissions. You can reach them at csscoperations@palmettogba.com or by phone at 1-877-534-2772.

This extension is good news — it gives you more time to stabilize your internal systems, ensure submission accuracy, and prepare for whatever the next phase of migration looks like. But it’s also a reminder: while the shutdown is postponed, it’s not canceled. Use this time wisely to stay audit-ready and ahead of future changes.
