2025 Medicare Part C & Part D Reporting Requirements & Data Validation

Guidance for DV Standard 6

Standard 6 is applicable only if an SO’s data systems underwent any changes during the reporting period. The DVC selects (N/A) in the EES if Standard 6 isn’t applicable to the reporting section or contract under review.

Implementation Guidance

Review documentation on data system changes and determine if changes to an SO’s data system adversely changed data reported by conducting the following activities:

  • Determine if there were any changes to data sources used for data collection and storage, data processing, analysis, and reporting for the reporting section under review.
  • Determine if data system changes were the root cause of any outlier notices from CMS for the reporting section under review.
  • Determine if the SO started any process or quality improvement activities during the reporting period specifically related to the data system change for the reporting section under review.
  • Determine if any changes to data systems during the reporting period adversely changed the validity of the SO’s data.
