Other disorders of arteries and arterioles (I77)
The ICD-10 code I77 series classifies various unusual and specific disorders of arteries and arterioles that do not fit common categories like atherosclerosis. These codes are used to identify conditions ranging from acquired arteriovenous fistulas to arterial dissections, strictures, ruptures, and arterial inflammatory diseases.
The section includes I77.0 for acquired arteriovenous fistulas, which covers conditions such as carotid cavernous fistula and surgically created vascular grafts. I77.1 addresses arterial strictures or stenoses that can involve vessels like the iliac or thoracic aorta. Ruptures of arteries, including trauma to arteries like the brachial or iliac, fall under I77.2. For fibromuscular dysplasia, a non-atherosclerotic artery disease affecting renal or carotid arteries, coders use I77.3. I77.4 covers celiac artery compression syndrome, an external narrowing of a major abdominal artery. Arteritis without a determined cause is captured by I77.6, including various forms of vasculitis such as ANCA-associated vasculitis (I77.82). Arterial dissections, specifying various arteries like carotid (I77.71), renal (I77.73), vertebral (I77.74), and more, are coded from I77.70 to I77.79. Other specified diseases include aortic ectasia (I77.81) and less common arterial conditions described under I77.89. When the disorder is unspecified, I77.9 applies.

Instructional Notations
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
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
AIDS Arteritis, Central Nervous System
Inflammation of ARTERIES in the CENTRAL NERVOUS SYSTEM that occurs in patients with ACQUIRED IMMUNODEFICIENCY SYNDROME or AIDS-RELATED OPPORTUNISTIC INFECTIONS.
Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis
Group of systemic vasculitis with a strong association with ANCA. The disorders are characterized by necrotizing inflammation of small and medium size vessels, with little or no immune-complex deposits in vessel walls.
Aorta
The main trunk of the systemic arteries.
Aortitis
Inflammation of the wall of the AORTA.
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.
Arteriviridae
A family of viruses, of the order NIDOVIRALES, containing spherical virions. In contrast to CORONAVIRIDAE, no protruding spikes are obvious on the surface.
Central Nervous System Vascular Malformations
Congenital, inherited, or acquired abnormalities involving ARTERIES; VEINS; or venous sinuses in the BRAIN; SPINAL CORD; and MENINGES.
Churg-Strauss Syndrome
Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from POLYARTERITIS NODOSA.
Endarteritis
Inflammation of the inner endothelial lining (TUNICA INTIMA) of an artery.
Equartevirus
A genus of the family ARTERIVIRIDAE.
Giant Cell Arteritis
A systemic autoimmune disorder that typically affects medium and large ARTERIES, usually leading to occlusive granulomatous vasculitis with transmural infiltrate containing multinucleated GIANT CELLS. The TEMPORAL ARTERY is commonly involved. This disorder appears primarily in people over the age of 50. Symptoms include FEVER; FATIGUE; HEADACHE; visual impairment; pain in the jaw and tongue; and aggravation of pain by cold temperatures. (From Adams et al., Principles of Neurology, 6th ed)
IgA Vasculitis
A systemic non-thrombocytopenic purpura caused by HYPERSENSITIVITY VASCULITIS and deposition of IGA-containing IMMUNE COMPLEXES within the blood vessels throughout the body, including those in the kidney (KIDNEY GLOMERULUS). Clinical symptoms include URTICARIA; ERYTHEMA; ARTHRITIS; GASTROINTESTINAL HEMORRHAGE; and renal involvement. Most cases are seen in children after acute upper respiratory infections.
Livedoid Vasculopathy
A rare cutaneous thrombotic disease due to occlusion of dermal vessels. It is characterized by purpuric maculae and ulcerations especially during summer which form scars called atrophie blanche. It is more associated with other syndromes (e.g., PROTEIN C DEFICIENCY; HYPERHOMOCYSTEINEMIA). Livedo reticularis with systemic involvement and stroke is SNEDDON SYNDROME.
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.
Polyarteritis Nodosa
A form of necrotizing non-granulomatous inflammation occurring primarily in medium-sized ARTERIES, often with microaneurysms. It is characterized by muscle, joint, and abdominal pain resulting from arterial infarction and scarring in affected organs. Polyarteritis nodosa with lung involvement is called CHURG-STRAUSS SYNDROME.
Retinal Vasculitis
Inflammation of the retinal vasculature with various causes including infectious disease; LUPUS ERYTHEMATOSUS, SYSTEMIC; MULTIPLE SCLEROSIS; BEHCET SYNDROME; and CHORIORETINITIS.
Rheumatoid Vasculitis
Necrotizing VASCULITIS of small and medium size vessels, developing as a complication in RHEUMATOID ARTHRITIS patients. It is characterized by peripheral vascular lesions, cutaneous ULCERS, peripheral GANGRENE, and MONONEURITIS MULTIPLEX.
Skin Diseases, Vascular
Skin diseases affecting or involving the cutaneous blood vessels and generally manifested as inflammation, swelling, erythema, or necrosis in the affected area.
Syphilis, Cardiovascular
Cardiovascular manifestations of SYPHILIS, an infection of TREPONEMA PALLIDUM. In the late stage of syphilis, sometimes 20-30 years after the initial infection, damages are often seen in the blood vessels including the AORTA and the AORTIC VALVE. Clinical signs include syphilitic aortitis, aortic insufficiency, or aortic ANEURYSM.
Systemic Vasculitis
A heterogeneous group of diseases characterized by inflammation and necrosis of the blood vessel walls.
Takayasu Arteritis
A chronic inflammatory process that affects the AORTA and its primary branches, such as the brachiocephalic artery (BRACHIOCEPHALIC TRUNK) and CAROTID ARTERIES. It results in progressive arterial stenosis, occlusion, and aneurysm formation. The pulse in the arm is hard to detect. Patients with aortitis syndrome often exhibit retinopathy.
Tunica Intima
The innermost layer of an artery or vein, made up of one layer of endothelial cells and supported by an internal elastic lamina.
Vasculitis
Inflammation of any one of the blood vessels, including the ARTERIES; VEINS; and rest of the vasculature system in the body.
Vasculitis, Central Nervous System
Inflammation of blood vessels within the central nervous system. Primary vasculitis is usually caused by autoimmune or idiopathic factors, while secondary vasculitis is caused by existing disease process. Clinical manifestations are highly variable but include HEADACHE; SEIZURES; behavioral alterations; INTRACRANIAL HEMORRHAGES; TRANSIENT ISCHEMIC ATTACK; and BRAIN INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, pp856-61)
Vasculitis, Leukocytoclastic, Cutaneous
Disorder characterized by a vasculitic syndrome associated with exposure to an antigen such as a drug, infectious agent, or other foreign or endogenous substance. Its pathophysiology includes immune complex deposition and a wide range of skin lesions. Hypersensitivity or allergy is present in some but not all cases.
