The new design has been updated to reflect the change in the underlying classification to ICD-10 5th edition, which came into effect on 1 April 2016. Spell-level trimpoints at the HRG level are split between elective and non-elective admissions. This means there are 3 trimpoints per HRG, 1 at episode level, and 2 at spell level.
Please read the summary of changesprovided with this release to understand the changes made since the HRG4+ 2015/16 Reference Costs Grouper and the update to the Grouper software application.

Casemix companion - a starting point and general reference guide for anyone interested in learning about the casemix classification system. It gives an introduction to HRGs, groupers, HRG4+ design concepts and grouping logic.

Code to group - this provides details of the constituent elements that contribute to HRG grouping, and contains reference data such as the ICD-10 and OPCS-4 codes utilised in the design, the procedure and diagnosis hierarchies, and the complication and comorbidities lists for HRG subchapters. It also includes information on Programme Budgeting Category (PBC) mapping and a comprehensive list of HRG codes and labels, including other fields used by the Grouper.
Test data and expected results - this contains sample data that can be used to test the grouper installation (running the sample data should result in 90% grouped, 10% ungrouped). The file format is representative of that in the sample RDFs, provided within the Grouper application. These files can be used as example patient data, or as a template to understand the required input to the Grouper to enable successful grouping.
Roots - this workbook identifies new HRGs, deleted HRGs and changes to existing HRG labels between reference costs designs.
Trimpoints - this identifies the episode and spell-level trimpoints used to collect reference costs for each HRG in a given year. Spell-level trimpoints at the HRG level are split between elective and non-elective admissions. This means there are 3 trimpoints per HRG, 1 at episode level, and 2 at spell level.
Grouper trimpoint methodology - provides the methodology for the calculation of the trimpoints.
