Valid for Submission
I77.6 is a billable diagnosis code used to specify a medical diagnosis of arteritis, unspecified. The code I77.6 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I77.6 might also be used to specify conditions or terms like antineutrophil cytoplasmic antibody positive vasculitis, aortitis, aortopulmonary window, arteriolitis, arteritis , chronic peri-aortitis, etc.
Unspecified diagnosis codes like I77.6 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I77.6:
Inclusion TermsInclusion Terms
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.
- Aortitis NOS
- Endarteritis NOS
Type 1 ExcludesType 1 Excludes
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.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code I77.6 are found in the index:
- - Angiitis - I77.6
- - Aortitis (nonsyphilitic) (calcific) - I77.6
- - Arteriolitis - I77.6
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Antineutrophil cytoplasmic antibody positive vasculitis
- Aortopulmonary window
- Chronic peri-aortitis
- Disorder of arteriole
- Glomerulonephritis co-occurrent and due to antineutrophil cytoplasmic antibody positive vasculitis
- Hughes Stovin syndrome
- Idiopathic aortitis
- Immune complex small vessel vasculitis caused by drug
- Infectious endarteritis of arterial duct
- Infective aortitis
- Infective endarteritis at site of aortic coarctation
- Infective endarteritis at site of aortopulmonary window
- Juvenile temporal arteritis
- Lumbosacral plexopathy due to vasculitis
- Lupus vasculitis
- Paraneoplastic vasculitis
- Primary systemic arteritis
- Primary systemic vasculitis
- Pulmonary hypertension due to vasculitis
- Pulmonary hypertension in systemic disorder
- Renal vasculitis
- Secondary aortitis
- Secondary systemic vasculitis
- Single organ vasculitis
- Small vessel vasculitis
- Small vessel vasculitis caused by immune complex
- Systemic vasculitis
- Temporal arteritis
- Vasculitis due to adenosine deaminase 2 deficiency
- Vasculitis due to and following viral infection
- Vasculitis of large artery
- Vasculitis of large intestine
- Vasculitis of medium sized vessel
- Vasculitis of mesenteric artery
- Vasculitis secondary to drug
- Vasculitis with glomerulonephritis
- ARTERITIS-. inflammation of any arteries.
- 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.
- 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.
- 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
- 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

Information for Patients
Also called: Angiitis
Vasculitis is an inflammation of the blood vessels. It happens when the body's immune system attacks the blood vessel by mistake. It can happen because of an infection, a medicine, or another disease. The cause is often unknown.
Vasculitis can affect arteries, veins and capillaries. Arteries are vessels that carry blood from the heart to the body's organs. Veins are the vessels that carry blood back to the heart. Capillaries are tiny blood vessels that connect the small arteries and veins.
When a blood vessel becomes inflamed, it can
- Narrow, making it more difficult for blood to get through
- Close off completely so that blood can't get through
- Stretch and weaken so much that it bulges. The bulge is called an aneurysm. If it bursts, it can cause dangerous bleeding inside the body.
Symptoms of vasculitis can vary, but usually include fever, swelling and a general sense of feeling ill. The main goal of treatment is to stop the inflammation. Steroids and other medicines to stop inflammation are often helpful.
