Other congenital malformations of peripheral vascular system (Q27) ICD-10-CM
The Q27 code range covers other congenital malformations of peripheral vascular system with 14 ICD-10-CM diagnosis codes. 12 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q27 range.
Arteriovenous Malformations
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
Congenital Phlebectasia
Widening of a vein that is present at birth.
About the Q27 Code Range
These blood vessel malformations are present at birth. They involve vessels such as umbilical and kidney arteries and vessels in the limbs or digestive system.
The subdivisions separate absent or underdeveloped umbilical arteries from narrowed or otherwise malformed kidney arteries. Q27.3 identifies artery-and-vein malformations. Its further subdivisions distinguish vessels in the upper limb, lower limb, digestive system, and kidney from other or unspecified sites. Other codes identify congenital phlebectasia and other specified or unspecified peripheral vessel malformations.
