Duplex ultrasound with standard non-vascular ultrasound
If the following is documented with a standard ultrasound, is it appropriate to add a duplex US? Does the information need to be stated in specific areas of the report? If only arterial inﬂow or venous outﬂow is documented, may a limited duplex be coded?
Separate order/accession or comment to explain why duplex is being added.
Gray Scale (B-mode)
Spectral Analysis (Acceleration rate, monophasic, biphasic waveforms, triphasic waveforms, peak systolic velocity (w/ measurements), resistive index (RI) (w/measurements), velocity (w/measurements), waveform analysis, pulsed doppler, spectral doppler)
