MRA (Magnetic Resonance Angiogram) Lower Extremity

CPT: 73725

1 Major Symptom or Complaint presented as primary indication

1.1 Aching pain in extremity, relieved by rest

  • 1.1.1 Suspected Peripheral Arterial Disease

1.2 Bleeding

  • 1.2.1 Suspected AVM

1.3 Claudication

  • 1.3.1 cramping pains caused by poor circulation of the blood to the muscles during exercise. True claudication is relieved with rest from exercise.

1.4 Erectile dysfunction

  • 1.4.1 Peripheral arterial disease suspected

1.5 Leriche syndrome

1.5.1 Leriche syndrome, a clinical triad of intermittent claudication involving the low back, buttocks, hip or thigh, impotency (which occurs in 30 to 50 percent of males with aortoiliac occlusive disease), and “global atrophy” of the lower extremities, reflecting the chronicity of low-grade ischemia.

1.5.2 Peripheral arterial disease suspected

1.6 Localized skin discoloration

1.7 Pain

  • 1.7.1 Suspected AVM

1.8 Pulsatile mass

  • 1.8.1 Suspected AVM

1.9 Ulceration

  • 1.9.1 Suspected AVM

3 Abnormal Physical Exam Finding presented as primary indication

3.1 Absent or diminished peripheral pulses

  • 3.1.1 Suspected Peripheral Arterial Disease

3.2 Ankle-brachial index (ABI) below 0.9

3.2.1 The ankle-brachial index (ABI) is calculated by measuring the systolic blood pressure in the brachial, posterior tibial, and dorsalis pedis arteries. The highest measurement in the ankles and feet is divided by the higher of the brachial measurements:

  • 3.2.1.1 The normal ABI is 1.0 to as high as 1.3
  • 3.2.1.2 An ABI below 0.9 indicates peripheral arterial disease. The lower the index the more severe the changes

3.3 Arterial bruit

  • 3.3.1 Suspected Peripheral Arterial Disease

3.4 Asymmetric blood pressure

  • 3.4.1 Suspected Peripheral Arterial Disease

3.5 Asymmetric pulses

  • 3.5.1 Suspected Peripheral Arterial Disease

3.6 Localized skin discoloration

  • 3.6.1 Suspected AVM

3.7 Palpable subcutaneous thrill

  • 3.7.1 Suspected AVM

3.8 Pulsatile mass

  • 3.8.1 Suspected AVM

3.9 Ulceration

  • 3.9.1 Suspected AVM
