Description

Sweden suggests a change in the NordDRG grouper regarding MDC 98 rule.

We have made a comparison of the test cases between the Department of Health and Welfare new grouper and Prodacapos and find that they interpret the rule for MDC 98 differently. This concerns the fact that the diagnoses in MDC 98 are automatically changed to MDC 12 and 13.

The Department of Health and Welfare new grouper takes into account if there is an MDC 98 diagnosis also as a secondary diagnosis. For example Z098 Control study for other treatment for other conditions and A562 Chlamydia infection of the urinary and genital tract, unspecified when grouping a patient case.

In the Prodacapo grouper, a case with a secondary diagnosis –from MDC 98 are grouped to DRG W29E Other factors affecting health status, not complicated.
In the Department of Health and Welfare new grouper the same case are grouped to DRG N59N Other diseases of the scrotum, penis etc. which is more correct when the secondary diagnosis concerns a patient of male gender.

The Nordic DRG Grouper (latest version 10022020) is taking into account the diagnosis codes from MDC98 and changes it to MDC12 or MDC13 depending on the sex of the patient.
I used the Swedish 2020 definition tables (the ones of NDMS) and two testcases with the same primary and secondary diagnosis as indicated in Liselotte's example.
The grouping result was DRG O50E/369N Menstrual & other female reproductive system disorders for female and DRG N59N/352 Other male reproductive system diagnoses.
The csv with two testcase and grouping results are attached. Please check if you get the same results.

Thanks Kristiina,
Good that the Nordic and SoS grouper do the same. Prodacapos doesn't, they group to:W29E Other factors affecting health status, not complicated. Who asks them to change / correct?

During the certification process of national 2020 groupers this difference was addressed and as far as NCC is aware of this should be corrected in Prodacapo's grouper now and it should take into account the MDC98 changing rule.

This is a technicla problem that probably has been already solved.
It is not a definition problem.
