About coding warfarin dysmorphism
The ICD-10-CM code for warfarin dysmorphism is Q86.2 (Dysmorphism due to warfarin).
Within Q86 (congenital malformation syndromes due to known exogenous causes, not elsewhere classified), Q86.2 is specifically for Dysmorphism due to warfarin. Related codes cover fetal alcohol syndrome (dysmorphic) (Q86.0), fetal hydantoin syndrome (Q86.1) and other congenital malformation syndromes due to known exogenous causes (Q86.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 794 (Neonate with Other Significant Problems, relative weight 1.4935), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
