Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Diseases of arteries, arterioles and capillaries
      (I70-I79)
      • Arterial embolism and thrombosis
        (I74)

I74.9 is a billable diagnosis code used to specify a medical diagnosis of embolism and thrombosis of unspecified artery. 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 I74.9 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 Classification

Clinical Information

  • Embolic Protection Devices

    vascular filters or occlusive devices that provide mechanical protection of the distal end organ from blood clots or embolism-causing debri dislodged during endovascular procedures.
  • Embolism

    blocking of a blood vessel by an embolus which can be a blood clot or other undissolved material in the blood stream.
  • Embolism and Thrombosis

    a collective term for pathological conditions which are caused by the formation of a blood clot (thrombus) in a blood vessel, or by blocking of a blood vessel with an embolus, undissolved materials in the blood stream.
  • Embolism, Air

    blocking of a blood vessel by air bubbles that enter the circulatory system, usually after trauma; surgical procedures, or changes in atmospheric pressure.
  • Embolism, Amniotic Fluid

    blocking of maternal circulation by amniotic fluid that is forced into uterine veins by strong uterine contraction near the end of pregnancy. it is characterized by the sudden onset of severe respiratory distress and hypotension that can lead to maternal death.
  • Embolism, Cholesterol

    blocking of a blood vessel by cholesterol-rich atheromatous deposits, generally occurring in the flow from a large artery to small arterial branches. it is also called arterial-arterial embolization or atheroembolism which may be spontaneous or iatrogenic. patients with spontaneous atheroembolism often have painful, cyanotic digits of acute onset.
  • Embolism, Fat

    blocking of a blood vessel by fat deposits in the circulation. it is often seen after fractures of large bones or after administration of corticosteroids.
  • Embolism, Paradoxical

    blockage of an artery due to passage of a clot (thrombus) from a systemic vein to a systemic artery without its passing through the lung which acts as a filter to remove blood clots from entering the arterial circulation. paradoxical embolism occurs when there is a defect that allows a clot to cross directly from the right to the left side of the heart as in the cases of atrial septal defects or open foramen ovale. once in the arterial circulation, a clot can travel to the brain, block an artery, and cause a stroke.
  • Intracranial Embolism

    blocking of a blood vessel in the skull by an embolus which can be a blood clot (thrombus) or other undissolved material in the blood stream. most emboli are of cardiac origin and are associated with heart diseases. other non-cardiac sources of emboli are usually associated with vascular diseases.
  • Intracranial Embolism and Thrombosis

    embolism or thrombosis involving blood vessels which supply intracranial structures. emboli may originate from extracranial or intracranial sources. thrombosis may occur in arterial or venous structures.
  • Ischemic Stroke

    stroke due to brain ischemia resulting in interruption or reduction of blood flow to a part of the brain. when obstruction is due to a blood clot formed within in a cerebral blood vessel it is a thrombotic stroke. when obstruction is formed elsewhere and moved to block a cerebral blood vessel (see cerebral embolism) it is referred to as embolic stroke. wake-up stroke refers to ischemic stroke occurring during sleep while cryptogenic stroke refers to ischemic stroke of unknown origin.
  • Neoplastic Cells, Circulating

    exfoliate neoplastic cells circulating in the blood and associated with metastasizing tumors.
  • Pulmonary Embolism

    blocking of the pulmonary artery or one of its branches by an embolus.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
