Other disorders of arteries and arterioles (I77) ICD-10-CM
The I77 code range covers other disorders of arteries and arterioles with 27 ICD-10-CM diagnosis codes. 23 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 I77 range.
Arterial Disorder
An impairment of the structure or function of the blood vessels which carry blood away from the heart.
Arterial Dissection
A tear within the wall of the artery.
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.
Arteritis
INFLAMMATION of any ARTERIES.
Carotid Artery Dissection
Spontaneous or traumatic separation of the layers of the carotid artery wall. It manifests with headache, neck pain, temporary vision loss, and/or ischemic stroke.
Dissection of Iliac Artery
A tear within the wall of an iliac artery.
Dissection of Renal Artery
A tear within the wall of a renal artery.
Dissection of Vertebral Artery
A tear within the wall of a vertebral artery.
Fibromuscular Dysplasia
A disorder characterized by fibrous thickening of the arterial wall resulting in narrowing of the arterial lumen. It most often affects the renal artery and less often the carotid artery and abdominal arteries. It can cause hypertension and aneurysm formation.
Malignant Atrophic Papulosis
Variously described as a vasculopathy, endovasculitis, or occlusive arteriopathy, this condition occurs in a benign cutaneous form and a lethal multiorgan systemic variant. It is characterized by a narrowing and occlusion of the lumen of small to medium-sized blood vessels, leading to ischemia and infarction in the involved organ systems. The etiology and pathophysiology are unknown.
Median Arcuate Ligament Syndrome
Compression of the CELIAC ARTERY by the median arcuate ligament, a fibrous band of the DIAPHRAGM, causing abdominal pain after eating and weight loss. OMIM: 116870
Necrosis of Artery
The death of arterial tissue.
Rupture of Artery
A tearing of the arterial wall.
Stricture of Artery
A pathologic narrowing of an artery.
About the I77 Code Range
These disorders affect arteries and arterioles, which are smaller arteries. They include acquired artery-to-vein connections, artery narrowing, and rupture.
I77 separates named artery disorders from other specified and unspecified disorders. I77.7 divides arterial dissection by the affected artery or limb. I77.81 divides aortic ectasia by chest, abdomen, both, or unspecified site.
