ICD-10 code for umbilical artery single

The ICD-10-CM code for umbilical artery single is Q27.0 (Congenital absence and hypoplasia of umbilical artery).

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

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 299 (Peripheral Vascular Disorders with MCC, relative weight 1.5842), DRG 300 (Peripheral Vascular Disorders with CC, relative weight 1.0464) and DRG 301 (Peripheral Vascular Disorders without CC/MCC, relative weight 0.7133), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
