Inclusion Terms
- Aneurysmal varix
- Arteriovenous aneurysm, acquired
Type 1 Excludes
- arteriovenous aneurysm NOS Q27.3
- presence of arteriovenous shunt fistula for dialysis Z99.2
- traumatic - see injury of blood vessel by body region
Type 2 Excludes
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
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 InformationClinical
Arteriovenous Fistula
an abnormal direct communication between an artery and a vein without passing through the capillaries. an a-v fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. the locations and size of the shunts determine the degree of effects on the cardiovascular functions such as blood pressure and heart rate.Central Nervous System Vascular Malformations
congenital, inherited, or acquired abnormalities involving arteries; veins; or venous sinuses in the brain; spinal cord; and meninges.Cirsoid Aneurysm
a rare arteriovenous malformation that affects the head and neck and manifests with nodules or papules due to the presence of tortuous dilated vessels in the subcutaneous tissues, usually of the scalp. it may be congenital or caused by trauma.
