CPT® Code 0311T

Deleted

The CPT® Code 0311T refers to a non-invasive procedure that involves the calculation and analysis of central arterial pressure waveforms, accompanied by interpretation and reporting of the findings. This procedure is significant in clinical settings as it provides a comprehensive assessment of central arterial pressure, which is crucial for evaluating cardiovascular health. Unlike traditional peripheral pressure monitoring methods, such as sphygmomanometry, central arterial pressure monitoring offers a more accurate representation of the quality and extremes of pulse pressure, including both systolic and diastolic measurements. The procedure begins with the application of a conventional blood pressure cuff to measure the brachial artery's systolic and diastolic pressures. Following this, a tonometer is utilized to applanate the radial or carotid artery, allowing for the capture of a pressure waveform. This waveform is then analyzed by a computer, which correlates the brachial artery pressure with the captured waveform to derive the central arterial pressure. The results obtained from this analysis are instrumental in guiding hypertensive treatment, monitoring the hemodynamic effects of atherosclerotic risk factors, and predicting potential cardiovascular events and outcomes.
