We See Dead People.

Higher quality data means higher HEDIS measures. Stars are just a bonus.

The challenge

Deceased members don’t disappear from your data—they stay “alive” in eligibility files, quality measurement, and outcomes reporting, quietly skewing the numbers your organization is measured on. The industry’s default mortality file is an inferior product, missing 8 out of 10 U.S. deaths and leaving those gaps hidden in plain sight.

“Master” implies complete. It’s not even close. And there’s another myth worth retiring alongside it: that industry accreditations for primary source verification require the Death Master File (DMF) specifically. It doesn’t. NCQA’s standards call for a reliable source of verification—not a mandate for the DMF. Organizations have more accurate options available and always have. Why not choose superior quality?

Two ways Berwyn closes the gap

Berwyn Group is the leader in population data management, offering the industry’s most advanced and trusted death audit solutions.

For organizations that want the most accurate, fully validated death audit available—with Berwyn handling the research and delivering only confirmed results—CertiDeath® is our gold standard.

For organizations that want a superior alternative to the industry’s inferior default file, BerwynDMF delivers more than 4x the coverage—no PII required, no workflow disruption.

Both are built to help health plans, health systems, and healthcare services companies manage the accuracy of the populations they serve.

The guarantee

If we don’t provide additional deaths in your population within the first 30 days, you don’t pay.
