The “PDPM Grouper JAR Package V2.2001.zip” is now available in the Downloads section below. This V2.2001 release is an update to adjust the OBRA logic for target dates on or after October 1, 2023.   

The logic for standalone OBRA assessments will be similar to the interim payment assessments logic.

This means that: 

    If A0310A=01 and A0310B=99, use column 1 (GGxxxxx1) 

    If A0310A=02-06 and A0310B=99, use column 5 (GGxxxxx5) 

This change will affect Nursing, Occupational Therapy, and Physical Therapy logic.

PDPM Grouper V2.1000

An updated version of the Patient Driven Payment Model (PDPM) Grouper V2.1000 has been posted in the Downloads section. This update is just a documentation update to clarify the following:

• Jars are packaged differently (snf-x.x.x-jar-with-dependencies removed). Instead, jars in the “lib” folder should be included on the classpath to avoid compilation issues (refer to snf.bat).
• The software now uses a Protobuf bin file in place of the original/plain CSV files for processing; however, to maintain consistency, we are still providing the corresponding CSV files in the src\main\resources\specTableCSV folder.

PDPM Grouper V2.0002 Posted

An updated version of the Patient Driven Payment Model (PDPM) Grouper has been posted in the Downloads section below with the new version number V2.0002 and will be implemented into the Minimum Data Set (MDS) Assessment Submission And Processing (ASAP) system on Thursday, January 6, 2022.This update addresses two issues with the Non-Therapy Ancillary (NTA) comorbidities mapping. First, it corrects an issue where diagnosis codes were mapped to NTA comorbidities as 1 to 1 mappings where 1 to 2 mappings were intended from the PDPM_International Classification of Diseases, Tenth Revision (ICD10)_Mappings_FY20XX Excel sheet. The list of affected diagnosis codes are: D89810, D89811, D89812, D89813, K7041, M3211, M3213, M3301, M3311, M3321, M3391, M3481, T8630, T8631, T8632, T8633, T8639, Z48280, Z943. Second, it fixes a spacing issue in the NTA comorbidity description name “Disorders of Immunity – Except: RxCC97: Immune Disorders”, which resulted in those points not adding up correctly during the NTA comorbidity score calculation.

Additionally, this new version was repackaged to address a security vulnerability with the third party library Log4J. The library was upgraded to v2.16.0. No changes were made to the PDPM/Skilled Nursing Facility (SNF) component itself to address the updated Log4J file.

Final Version of Java PDPM Grouper Posted

An update to the FINAL version of the Java Patient Driven Payment Model (PDPM) Grouper, v.2.0 has been posted in the Downloads section below. This update to Skilled Nursing Facility (SNF) addresses two issues. It corrects a logic issue on “Behavioral Symptoms and Cognitive Performance” under Nursing payment component. When C0100 and C0500 are both dashes (not assessed), the grouper returned an incorrect nursing classification. A nursing component of BAB1 may be being returned in error. It also corrects a Non-Therapy Ancillary (NTA) comorbidity score calculation. The Grouper was calculating I8000: End-Stage Liver Disease and I8000: Immune Disorders as 2 points each but those should only count as 1 point each.

September 21, 2021

Final Version of PDPM Grouper v.2.0 Posted

An update to the FINAL version of the Java Patient Driven Payment Model (PDPM) Grouper, v.2.0 has been posted in the Downloads section below. This update to the PDPM package is to enable vendor direct integration with the jars through a provided batch script and to update the snf-2.0.0-qa-test.jar file. Users can reference the readme.txt within the jars/directory for more details. Note that all other jars remained the same.

The PDPM Grouper Java Archive (JAR) Package V2.0 technical documentation was updated with the correct email address for vendor support questions. Also, the note regarding logic updates to the Non-Therapy Ancillary (NTA) Comorbidity Score Calculation for the Minimum Data Set (MDS) 1040 Items refers to a change in the GROUPER logic that was made in January 2021 to correct a technical error that allowed two points to be added to the total NTA score instead of one point as originally intended by the PDPM coding logic. While this technical error affected very few stays (0.075%) from October 2019 to December 2020, a description of the logic change was not included in the documentation when the revised GROUPER DLL was posted in January 2021. The coding logic contained in the current production GROUPER since January 2021 and in the Java GROUPER that is effective October 2021 should be utilized from this point forward.

A beta test version of the Java PDPM Grouper has been posted. This version is to allow users to familiarize themselves with the Java program. The Fiscal Year 2022 PDPM Grouper, v.2.0, will be distributed only in a Java version.

These files are located in the Downloads section below.

February 04, 2021

An update to the PDPM Grouper DLL package was posted. This is NOT a change to the previously posted DLL file itself, just supporting information. The documentation file was updated, as there were NTA mapping changes not previously documented. Also, one file in the source code zip from the previous package, mdsgrouper,h, was not the latest version. The correct version is included in this updated package. NOTE: the DLL was compiled with the latest version of mdsgrouper.h in the previous package. Therefore, there is no change to the DLL file itself.

An updated errata (V3.00.7) was posted for the FINAL version (v3.00.1) of the MDS 3.0 Data Specifications, currently in production. The resolution to issue 17 in the previous errata was flawed, as the addition of edit -3963d prevented submission of IPA inactivations. Therefore, edit -3963d has been suspended for now, and will be revised in a future release.

The updated PDPM package and revised errata are posted in the Downloads section below.

January 07, 2021

An update to the PDPM Grouper DLL has been posted, along with its source code and test cases.

(Note that codes M35.81 and M35.89 replace code M35.8, which should no longer be used on assessments with target date on or after January 1, 2021.)

In addition, the lookup files containing the allowable ICD-10 codes for item I0020B (as of January 1, 2021) have been updated to contain the new ICD-10 codes listed above, as well as remove M35.8. They are posted as a separate ZIP file.

These files are located in the Downloads section below.

January 01, 2021

The Validation Utility Tool (VUT) is a software utility that can be used to validate MDS 3.0 submission files in XML format. The tool enforces the edits that are mapped to the MDS 3.0 items as published in the MDS 3.0 Data Specifications.

The v3.5.0 VUT continues to support older data specification versions and has been updated to incorporate Issue 17 in Errata v3.00.6 to the current Data Specifications, as well as new ICD codes and is in effect on January 1, 2021. The MDS VUT version 3.5.0 is now available in the Downloads section at the bottom of this webpage.

Please note that there are edits which the VUT cannot support because they are edits against existing ASAP system data. The VUT does not interface with ASAP therefore it cannot confirm those edits. The VUT does not currently interface with the RUG III and IV DLLs, or the new PDPM DLLs, therefore it does not recalculate and confirm that Grouper values are correct.

October 09, 2020

An update to the PDPM Grouper DLL has been posted, along with its source code and test cases. This version, V1.0008, corrects an issue with a dynamic array that was not consistently reinitialized when processing multiple assessments within a short time frame. This occasionally caused incorrect PDPM recalculation results when processing pre- and post- 10/01/2020 assessments.

September 29, 2020

An update to the PDPM Grouper DLL has been posted, along with its source code and test cases. This version, V1.0007, adds six ICD-10 codes that were inadvertently excluded from the NTA calculation: T8484XA, T8389XA, T8321XA, T82399A, T82392A, and T83021A.

September 14, 2020

The FINAL version of the PDPM Grouper DLL V1.0006 has been posted, along with its source code and test cases. This version supports the calculation of PDPM payment codes on OBRA assessments when not combined with the 5-day SNF PPS assessment, specifically the OBRA comprehensive (NC) and OBRA quarterly (NQ) assessment item sets. Note that the grouper will return 4-character codes for these OBRAs.

It is important to include the control item STATE_PDPM_OBRA_CD (as defined in the V3.00.5 errata for the FINAL version (v3.00.1) of the MDS 3.0 Data Specifications) for assessments with target date on or after October 1, 2020.

Note that this FINAL version supports the ICD-10 codes that are defined in the data specifications as valid for item I0020B for FY2021. Also, please note that the grouper expects valid FY2021 ICD-10 codes for I8000A-J when processing assessments with target date on or after October 1, 2020.

These changes will go into production on October 1, 2020. As a result, two edits will be revised. These changes will facilitate calculation of PDPM HIPPS codes on OBRA assessments for states that wish to have this calculation performed.

May 15, 2020

In response to State Medicaid Agency and stakeholder requests, CMS has updated the MDS 3.0 item sets (version 1.17.2) and related technical data specifications. These changes will support the calculation of PDPM payment codes on OBRA assessments when not combined with the 5-day SNF PPS assessment, specifically the OBRA comprehensive (NC) and OBRA quarterly (NQ) assessment item sets, which was not possible with item set version 1.17.1. This will allow State Medicaid Agencies to collect and compare RUG-III/IV payment codes to PDPM ones and thereby inform their future payment models.

The changes to the technical data specifications that support these modifications are contained in the Errata v3.00.4 which can be accessed in the file: MDS 3.0 data specs errata (v3.00.4) Final 04-30-2020 in the Downloads section below. Supporting materials including the 1.17.2 Item Change History report and the revised 1.17.2 Item Sets can be accessed in the file: MDS 3.0 Final Item Sets v1.17.2 for October 1 2020 zip also posted in the Downloads section below.

Please confirm with your State Medicaid Agency if your State will be requiring the calculation of the PDPM payment codes on the OBRA assessments when not combined with a 5-day SNF PPS assessment.

March 27, 2020

CMS is delaying the Minimum Data Set (MDS) 3.0 v1.18.1 release, which had been scheduled for October 1, 2020, in response to stakeholder concerns. The MDS item sets are used by Nursing Home and Swing Bed providers to collect and submit patient data to CMS. This MDS data informs payment, quality, and the survey process.

In December of 2019, CMS posted a draft of the MDS 3.0 item set v1.18.0 and received feedback from our stakeholders. We would like to thank the stakeholders for sharing their concerns regarding the proposed changes to the MDS 3.0 item sets and more specifically the removal of the Section G items from OBRA assessments.

The MDS changes CMS planned for October 1, 2020 will now be delayed. CMS staff are actively engaged in discussions with various stakeholders, regarding the various changes, the impacts of these changes, as well as, the compressed timeline to educate and train facility staff and update software and IT systems.

Please direct any comments or questions regarding the above information to MDSCodinganswers@cms.hhs.gov mailbox.
