Compilation & Archiving of DV Work Papers

When the SO gets the archive from the DVC, the SO adds the documentation of its DVC selection process to the archive, including how the DVC meets the minimum qualifications, credentials, and resources listed in Appendix A: Standards for Selecting a Data Validation Contractor.

This includes maintaining the documentation that all users have completed the 2025 DV Training.

The SO keeps this complete archive for the 10-year retention period, following federal regulations in 42 CFR 422.504(d) and 423.505(d).

CMS may ask for and audit work papers at its discretion.

Remember, you can find the Medicare Part C and Part D Reporting Requirements Data Validation Procedure Manual on the Part C and Part D Data Validation webpage. Open the 2025 Parts C and D Data Validation file under the Downloads section on the webpage to access the DV Manual.
