Another year of Medicare Part C and Part D Data Validation (DV) audits is in the books. Here are a few key takeaways and best practices from this year’s experience: 1. Share CMS Technical Specifications Early Ensure all report owners receive CMS technical specs and reporting requirements well in advance. This promotes clear understanding of required data elements and ensures alignment for HPMS submissions and audit readiness. 2. Strengthen Internal Quality Control A robust internal QC process is essential. Assign a lead to manage this effort and establish standardized checks. Block time in March to confirm that what’s submitted in HPMS accurately reflects your intended data. 3. Validate Vendor Data Throughout the Year Accurate reporting hinges on reliable vendor data. Set expectations for vendors with delegated reporting responsibilities to provide both summary and detailed data. Request clear references or documentation to interpret results effectively. 4. Create a Centralized Measure Reporting Library Maintain a central repository that includes final submissions (HPMS summary and supporting detail), measure logic, and relevant policies and procedures. These documents not only support measure reporting but also fulfill many DV audit documentation requirements. Congratulations to our Medicare clients on another successful reporting year. As always, early preparation and strong processes are the foundation of accurate reporting and DV audit success.
