Radiology Coding Alert

Question: If we perform extremity arterial vascular studies (93922-93923) on the left leg and arm, how should I code this? Ohio Subscriber Answer: The particular modifiers you use will depend on payer preference, but there are some guidelines you can use to get you on your way to accurate coding. Unilateral: The case you describe involves studying only one side of the body (unilateral). The codes for the service represent bilateral services (emphasis added): 93922 -- Noninvasive physiologic studies of upper or lower extremity arteries, single level, bilateral (e.g., ankle/brachial indices, Doppler waveform analysis, volume plethysmography, transcutaneous oxygen tension measurement) 93923 -- Noninvasive physiologic studies of upper or lower extremity arteries, multiple levels or with provocative functional maneuvers, complete bilateral study (e.g., segmental blood pressure measurements, segmental Doppler waveform analysis, segmental volume plethysmography, segmental transcutaneous oxygen tension measurements, measurements with postural provocative tests, measurements with reactive hyperemia). Because you aren't reporting the [...]
