Medicare Advantage and Part D Data Validation Audit Experience and Efficiency

Medicare Advantage organizations and Part D Plan Sponsors require annual third-party Data Validation Auditing (DVA) to test their Part C and Part D CMS reporting.


ATTAC Consulting Group (ACG) is one of the nation’s leading CMS Part C and Part D Data Validation Auditors. As a firm serving Medicare Advantage (MA) and Part D Plans, ACG navigates the systems, data sets and CMS reporting every day. This experience allows us to conduct an efficient and accurate DVA audit of your Plan’s Part C and Part D reporting.

Focus & Efficiency

ACG’s DVA audit will thoroughly test your internal data as well as that of your PBM and other delegates.

But getting the numbers right is only part of the story. ACG uses a proven audit framework and process that is focused and targeted, keeping the audit streamlined. Because we work with most major PBMs, we are extremely efficient in testing Part D data and reporting. Our audit teams start early, lead you through the process, and keep you informed all the way through. DVA isn’t painless, but we will make it as efficient as possible.

ACG Qualifications

ACG meets CMS DVA auditor standards in Part C and Part D experience, systems expertise and data security. We have years of experience and have performed hundreds of audits in the Medicare Advantage, Part D and Medicaid realms.
