ICD-10 code for congenital phlebectasia

The ICD-10-CM code for congenital phlebectasia is Q27.4 (Congenital phlebectasia).

Within Q27 (other congenital malformations of peripheral vascular system), Q27.4 is specifically for congenital phlebectasia. 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), arteriovenous malformation (peripheral) (Q27.3), other specified congenital malformations of peripheral vascular system (Q27.8) and congenital malformation of peripheral vascular system, unspecified (Q27.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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.
