Which code is used to report the measurement of peripheral arterial sound using an open approach?

The code 4A030H1 is correct for reporting the measurement of peripheral arterial sound using an open approach. This code falls under the section for Measurement in the ICD-10-PCS coding system, where the first character "4" indicates the procedure is a measurement. The second character "A" specifies that the procedure is involving a physiological measurement.

The third character "0" denotes that the measurement is in relation to blood pressure or flow, while the "3" in the fourth character indicates that the specific location of the measurement is peripheral arteries. The last character "H1" signifies that the approach used for the measurement is open, which is consistent with the nature of the procedure described.

In context, the other codes do not accurately represent the measurement of peripheral arterial sound through an open approach. Each of the incorrect options either represent different measurements or approaches that do not align directly with the specified procedure.
