Medicare Part C & D Data Validation Audit (DVA)

Meeting Your Data Validation Audit Needs:

Attest has been conducting data validation projects since 1997 and Medicare DVA projects since their inception in 2011. In 2025, we audited more than 25% of the total contracts nationwide.

Our large and diverse market share has enabled us to continually refine our internal processes and tools to reflect best practices. As such, our reputation of excellence and client satisfaction is reflected in our client growth and retention.

We have never missed a reporting deadline. In 2025, we marked all contracts final in advance of the CMS deadline. We assure client agreement with the Data Validation results via ongoing tracking and plan review of draft findings prior to submission to CMS.

How it works:

A core audit team is assigned to each audit. The core team coordinates the efforts of all resources and serves as the primary liaison with your company year-round. Additional resources for source code review and census/sample validation assist the core audit team as needed throughout the project. Access to greater staff expertise allows for efficient completion of documentation review and responses to your communications throughout the year.

We are committed to involving clients throughout the process and keeping them informed of any possible findings. We will share a regular issue log, timeline, and status of key deliverables beginning in April of the audit year. We believe in a no surprises approach, meaning that you will know the status of your DVA throughout the entire process. Here at Attest, we are committed to conducting your Data Validation Audit review in an open, efficient, and reassuring manner.
