About Q86.2
Q86.2 is the ICD-10-CM diagnosis code for Dysmorphism due to warfarin. It belongs to category Q86 (congenital malformation syndromes due to known exogenous causes, not elsewhere classified), block Q80-Q89 (other congenital malformations) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 760.79 (other noxious influences affecting fetus or newborn via placenta or breast milk).
