Home Health PPS Grouper Software (HHGS)

Home Health PPS Grouper Software (HHGS) Package (for claims starting 01-01-2026)

The January 2026 release of the HH PPS Grouper software (v07.0.26) is now available in the “Downloads” section of this webpage. A summary of the changes for what is included in the v07.0.26 HH PPS Grouper software update is listed below.

In November 2018, CMS finalized a case-mix classification model, the Patient-Driven Groupings Model (PDGM), effective beginning January 1, 2020. The PDGM, or Home Health PPS Grouper Software (HHGS), relies more heavily on clinical characteristics and other patient information to place home health periods of care into meaningful payment categories and eliminates the use of therapy service thresholds. In conjunction with the implementation of the PDGM, there will be a change in the unit of home health payment from a 60-day episode to a 30-day period.

The following reflects the changes included in the v07.0.26 software update:

• There are no logic or interface changes for v07.0.26

The following tables impacting grouping logic and HIPPS code assignments are updated effective January 1, 2026 (see details in the Summary of Changes document provided with the software):

• Clinical Group for updates to OASIS point values
• FI Response for updates to functional impairment threshold values
• Comorbidity Group for updates to the list of comorbidity groups marked for low comorbidity adjustment
• Comorbidity Interaction for updates to the list of comorbidity interaction pairs for high comorbidity adjustment

6-10-2025 Home Health PPS Grouper Software (HHGS) Package (for claims starting 01-01-2025) – Interactive GUI Compatible with Java 17 and Higher

Due to recent changes involving Oracle's decision to discontinue commercial support for JavaFX 8, the Home Health Grouper Interactive GUI for the January 2025 version 6.0.25 has been replaced to be compatible with Java version 17 and higher. 

Note that no immediate action is required for users in which the Interactive GUI is still functioning; however, effective October 1, 2025, the Grouper will be optimized exclusively for Java 17 and above.

Notice Regarding Upcoming Releases of the Home Health PPS Grouper

The October 2025 version of Home Health PPS Grouper has been upgraded to Java software version 17.  Home health agencies and their software vendors who implement the HH Grouper in a mainframe environment are impacted by this change as well. CMS had previously notified users of this upgrade.

With this release, one Common Business-Oriented Language (COBOL) Java bridge module is provided that will utilize the 64-bit, Java 17 JVM environment.  The installation guides for the program provide notice of the changes.

The Java jar has been developed and tested using Java 17; Java 8 support is no longer available as of the v06.1.25 October 1, 2025 release.
