About coding peripheral vascular system hypoplasia
The ICD-10-CM code for peripheral vascular system hypoplasia is Q27.8 (Other specified congenital malformations of peripheral vascular system). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q27.8.
Within Q27, choose Q27.8 (Other specified congenital malformations of peripheral vascular system) only when documentation doesn't support a more specific option: congenital absence and hypoplasia of umbilical artery (Q27.0), congenital renal artery stenosis (Q27.1), other congenital malformations of renal artery (Q27.2), arteriovenous malformation (peripheral) (Q27.3), congenital phlebectasia (Q27.4) and congenital malformation of peripheral vascular system, unspecified (Q27.9).
Don't report Q27.8 together with the conditions in its Excludes1 note: arteriovenous malformation (Q27.3-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
