Notes:
The National Schedule of Reference Costs, developed by the Department of Health, uses Healthcare Resource Groups (HRGs) as the basis for costing in-patient and day case services. Healthcare Resource Groups (HRGs) are derived from existing CDS data items using an algorithm and a software package developed by the NHS Information Authority (Casemix Programme).

HRG DOMINANT GROUPING VARIABLE-PROCEDURES (DGVP) is a field derived by the HRG Acute Inpatient Grouper. It represents the procedure that the HRG grouping algorithm has identified as having the greatest effect upon the resources consumed by a PATIENT. It is required for the production of the National Schedule of Reference Costs reports.

The DGVP has the same data format, rules and attributes as OPCS-4 codes for PATIENT PROCEDURE, see also PROCEDURE CODING.

DSCN 08/2000 includes HRG DOMINANT GROUPING VARIABLE-PROCEDURES in the core CDS to standardise the handling of this data item within the CDS, the NHSCDS EDIFACT message and the NWCS database. It is mandatory from 01/10/2001
