NOTE: DUE TO CHANGES IN THE WAY CMS DISTRIBUTES THE DEFINITION OF THE US FEDERAL DRG GROUPER, V40 (released October 1s, 2021) IS THE LAST VERSION WE WILL BE SUPPORTING. WE WILL LEAVE THIS SITE UP FOR A YEAR IN CASE PEOPLE WANT TO BUY GROUPERS FOR VERSION 40 AND BEFORE BUT WE WILL NOT BE UPDATING THIS PRODUCT LINE ANY FURTHER. WE ARE CONFIDENT THAT MANY CUSTOMERS WILL BE ABLE TO USE THE CMS JAVA IMPLEMENTATION AS-IS. CONTACT US IF YOU NEED SOME KIND OF CUSTOM SUPPORT OVER AND ABOVE WHAT CMS HAS RELEASED.

Welcome to the web site for DRGGroupers. We sell a range of products and services, all of which are related to assigning Diagnosis Related Groups (DRGs) to inpatient stays.

 We provide a service to assign DRGs to your data sets if you don't want to run or install software and just want DRGs assigned to your inpatient encounter records. We recently moved that service into the cloud and automated our end, allowing us to dramatically drop the price. Follow the “SERVICES” link in the navigation menu above.

We sell an application to assign DRGs called DRGFilt. DRGFilt is available in both Windows and Linux versions. Follow the “SOFTWARE” link in the navigation bar above.

We sell software tools to allow you to add DRG assignments to your app or system. Follow the “SOFTWARE” link in the navigation bar above.

We still sell and support ICD9-based grouping products or services. We have yet to integrate our ICD9-based offerings into our new on-line presence. Contact us directly if you are interested in an ICD9-based product or service.

NOTE: we support MS-DRGs, the DRG algorithm released by the US Federal government's Centers for Medicare & Medicare Services (CMS). We do not currently support APR-DRGs, refined DRGs or any other variant of the MS-DRGs.
