About Q27.3

Q27.3 is the ICD-10-CM diagnosis code for arteriovenous malformation (peripheral). It belongs to category Q27 (other congenital malformations of peripheral vascular system), block Q20-Q28 (congenital malformations of the circulatory system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within Q27 (other congenital malformations of peripheral vascular system), Q27.3 is specifically for arteriovenous malformation (peripheral). Related codes cover congenital absence and hypoplasia of umbilical artery (Q27.0), congenital renal artery stenosis (Q27.1), other congenital malformations of renal artery (Q27.2), congenital phlebectasia (Q27.4), other specified congenital malformations of peripheral vascular system (Q27.8) and congenital malformation of peripheral vascular system, unspecified (Q27.9).

To report this condition, pick the subcode that matches the documentation: Q27.30 (unspecified), Q27.31 (limb), Q27.32 (limb), Q27.33 (vessel), Q27.34 (vessel) and Q27.39 (site).

Don't report Q27.3 together with the conditions in its Excludes1 note: acquired arteriovenous aneurysm (I77.0).

The conditions in its Excludes2 note aren't part of Q27.3, but may be coded alongside it if the patient has both: arteriovenous malformation of cerebral vessels (Q28.2) and arteriovenous malformation of precerebral vessels (Q28.0).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
