Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Diseases of arteries, arterioles and capillaries
      (I70-I79)
      • Other disorders of arteries and arterioles
        (I77)

I77.6 is a billable diagnosis code used to specify a medical diagnosis of arteritis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

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.

Clinical Information

  • Arteritis

    inflammation of any arteries.
  • Equartevirus

  • 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)
  • 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.
  • 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)
  • 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

  • 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.
  • Endarteritis

    inflammation of the inner endothelial lining (tunica intima) of an artery.
  • Aortitis

    inflammation of the wall of the aorta.
  • 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.
  • 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.
  • Aorta

    the main trunk of the systemic arteries.
  • Mononeuritis Multiplex

    a painful asymmetric asynchronous sensory and motor peripheral neuropathy involving isolated damage to at least 2 separate nerve areas; associated with (but not limited to) systemic disorders such as diabetes, vasculitis, amyloidosis, direct tumor involvement, polyarteritis nodosa, rheumatoid arthritis, systemic lupus erythematosus, and paraneoplastic syndromes. it also may be associated with lyme disease, wegener's granulomatosis, sjogren syndrome, cryoglobulinemia, hypereosinophilia, temporal arteritis, scleroderma, sarcoidosis, leprosy, acute viral hepatitis a, and acquired immunodeficiency syndrome.

Patient Education


Vasculitis

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.
