Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Diseases of arteries, arterioles and capillaries
      (I70-I79)
      • Other peripheral vascular diseases
        (I73)

I73.9 is a billable diagnosis code used to specify a medical diagnosis of peripheral vascular disease, 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 I73.9 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

  • Intermittent Claudication

    a symptom complex characterized by pain and weakness in skeletal muscle group associated with exercise, such as leg pain and weakness brought on by walking. such muscle limpness disappears after a brief rest and is often relates to arterial stenosis; muscle ischemia; and accumulation of lactate.
  • Peripheral Arterial Disease

    lack of perfusion in the extremities resulting from atherosclerosis. it is characterized by intermittent claudication, and an ankle brachial index of 0.9 or less.
