Oth congenital malformations of peripheral vascular system

This code represents various congenital abnormalities of the peripheral arteries, veins, or lymphatic vessels that are not specifically classified elsewhere. These malformations are present at birth and can affect blood flow, vessel structure, or lymphatic drainage in the extremities or other peripheral areas.

Use this code for documented congenital vascular anomalies of the peripheral system that are not arteriovenous malformations (AVMs) or other more specific congenital vascular codes. Examples include congenital venous malformations (excluding AVMs), lymphatic malformations, or other specified arterial anomalies of the extremities. Documentation should clearly state the congenital nature and the specific type of peripheral vascular malformation.

• Ensure the documentation explicitly states "congenital" and specifies the type of peripheral vascular malformation.
• Carefully review documentation to differentiate from acquired vascular conditions or more specific congenital codes.
• Always check for an associated arteriovenous malformation (AVM) as this is an Excludes1 note; if an AVM is present, a code from Q27.3- should be used instead.
