KEY FACTS

  • Terminology

    TERMINOLOGY

    • Description

      • Percentage of final reports for carotid imaging studies (neck MRA, neck CTA, neck duplex ultrasound, carotid angiogram) performed that include direct or indirect reference to measurements of distal internal carotid diameter as denominator for stenosis measurement
    • Rationale

      • Accurate assessment of degree of carotid artery stenosis is essential to guiding proper treatment decisions for patients with carotid artery disease. Trials have demonstrated ability of degree of carotid artery stenosis to predict which patients will receive greatest benefit from surgical intervention. To ensure accurate assessment of stenosis, it is important to use standardized, validated approach. Rothwell et al. demonstrated significant differences between measurements of stenosis made using different methods of measurement.
    • Instructions

      • This measure is to be submitted each time carotid imaging study is performed during performance period for all patients, regardless of age. There is no diagnosis associated with this measure. Merit-Based Incentive Payment System (MIPS)-eligible clinicians who provide professional component of diagnostic imaging studies of carotids will submit this measure.
    • Numerator

      • Final reports for carotid imaging studies that include direct or indirect reference to measurements of distal internal carotid diameter as denominator for stenosis measurement
    • Denominator

      • All final reports for carotid imaging studies (neck MRA, neck CTA, neck duplex ultrasound, carotid angiogram) performed
