Published on 

Wednesday, March 13, 2024

Did You Know?

In the February 2024 edition of The Livanta Claims Review Advisor, Livanta reported findings from their second year of higher-weighted diagnosis related groups (HWDRG) validation reviews completed from November 1, 2022 through October 31, 2023. They note in the newsletter that these types of reviews “involve validation of codes on the claim by credentialed coding auditors and clinical review by board-certified practicing physicians as appropriate.”


Coding auditors utilize official coding guidelines, the American Hospital Association (AHA) Coding Clinics, and other authoritative coding references to complete their DRG validation reviews.  


Why It Matters?

When a hospital submits a record for a HWDRG, the review may also include a review to determine if the documentation also supported the medical necessity of an inpatient admission. The following table highlights a compare of Livanta’s Year One and Year Two review results.
