It was decided during EG meeting that the changes will be done in 2024 PL version, change concerns the NDMS, grouper (Nordic and national) and all def. tables (xls, json, csv).
This case remains open.

This is to clarify the issues which require changes in NordDRG tools (NDMS, grouper, def. tables). Based on that, the original text of this ticket was changed from "DRG-MDC vs DG-MDC" to “Changes required in NordDRG tools (NDMS, grouper, def. tables)” to reflect the actual content of this ticket.

The issues are taken from a Word file attached to #822. 

They are not directly related to transition to ICD-11 but given that the transition will require changes in NDMS, grouper and/or def.tables anyway, it would make sense to manage all the necessary changes at once. 

The suggested changes are as follows:

1. Change the heading ‘mdc’ in the table drglogic to ‘mdc_dg’ (= mdc of diagnosis) and the heading ‘mdc’ in the table drg_name to ‘mdc_drg (= mdc of drg)’ This will show that the term MDC is used in two different contexts in NordDRG
2. In the table drg_logic, rename the columns procpro and secpro to procpro1 and procpro2, similar to the dgprop columns. The term “secpro” is not present in the table proc_feat and the meaning is not obvious. 
3. Harmonise the abbrevation of grouping features throughout the def.tables (and NDMS and grouper), no matter what table they are in. The differences in abbreviations are:
   • Principal diagnosis property
     • pdgprop in table drg_logic & pdgprop_name
     • PDGPRO in table dg_feat
   • Operation room procedure property
     • or_proc in table drg_logic
     • OR in table proc_feat
   • Procedure property
     • procpro in table drg_logic
     • PROCPR in table proc_feat
     • procprop in table procprop_name
4. Extra columns in the table drglogic for administrative parameters as the type of care, type of contact and type of profession of the health care personal. Currently they are in the fields for diagnoses and procedures. 
5. Extra columns in the table drglogic for interventions. Now there are only two columns for interventions so the columns dgprop 1-4, originally meant for diagnoses, have to be used also for interventions if a grouping rule is based on more than two procedure codes. 
6. Enable multiple coding for procedures (similar to asterisk-dagger for diagnoses) so that general qualifiers (NCSP codes beginning with Z) are hooked to the right intervention code. With the present logic, an irrelevant bilateral procedure (e.g. peripheral intravenous catheters) can lead to a DRG for major bilateral interventions (e.g. DRG 471N ‘Bilateral or multiple major joint procs of extremities’). If the problem will be solved in ICHI, we can skip this suggestion.

This case remains further active.

This case was discussed in the meeting. The tracker of the ticket will be changed to development initiative. The ticket remains further active, waiting for the implementation of ICD-11.
