Dignosis category 30M05 ‘Non-malignant breast disorders’ is a residual category with non standard coding
When MDC 30 was formed by splitting the breast disorders from MDC 09 the categories retained their last two characters (09M04=>30M04 and 09M05 => 30M05). However, 30M05 really is a residual category and 30M05 does not appear in the logic table. All other residual categories have coding ‘xxM99’ where xx is the MDC of the category.
This non standard coding causes problems in the maintenance.
Technical change
The category is changed from 30M05 to 30M99. 34 codes (form ICD+) are changed to 30M99. Logic table changes are not needed. The property 30X99 is already added to the dx’s with 30M05 and thus that will neither change.
DRG change
The grouping is not affected by the change.

This change seems logical. Just one question - will you keep the text "Non-malignant breast disorders" or should it be "Other breast disorders"?
