Basic about Cpt Code 93923 & 92922

CPT codes in Radiology coding are little difficult to learn and apply. Here, we are dealing with codes, which have high dollar value, so it is very important to understand the main concept behind procedure codes. I have given many tips for coding different CPT codes and today also we will learn few more coding tips. So, we are here to know about CPT code 93923, which is very confusing while coding radiology charts. Cpt Code 93923 has a brother with CPT code 93922. These CPT codes are used to code the vascular procedure codes. We have learnt previously coding Cpt code for Ultrasound aorta, Ultrasound renal and  Ultrasound abdomen studies. There is very little difference between 93922 and 93923 CPT codes, which generally confuses the medical coders while coding charts. So, first we will just check out the code description for CPT code 93923 and 93922.

cpt code 93923

93922Noninvasive physiologic studies of upper or lower extremity arteries, single level, bilateral (eg, ankle/brachial indices, Doppler waveform analysis, volume plethysmography, transcutaneous oxygen tension measurement).
93923Noninvasive physiologic studies of upper or lower extremity arteries, multiple levels or with provocative functional maneuvers, complete bilateral study (eg, 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).

The CPT codes are based on the ABI (Ankle Branchial Index) test. Tha ABI test is done to check for any risk related to Peripheral Artery Disease (PAD). In this condition the arteries of extremities, legs or arms, are narrowed or blocked. Patients suffering from peripheral artery disease are more at a risk of heart attack, leg pain, poor circulation of blood and stroke.

Concept about Cpt code 93923 and 93922

Now, as we see, the description for CPT code 93922 involves noninvasive study of either both Lower extremity or upper extremity arteries at a single level. A single level study can be evaluation of Doppler waveform analysis, volume plethysmography and/or transcutaneous oxygen tension measurement at each ankle. Same single level evaluation can be done on upper extremities as well. Moreover, when both the upper and lower extremities are studied we have to use twice 93922 along with 59 or XS modifier depending on the client guidelines. So, hope you have understood when to code CPT code 93922 in non-invasive studies.

Cpt Code 93923 noninvasive studies are done on multiple levels. This is major difference between CPT code 93922 and 93923. Cpt Code 93923 involves study of either upper or lower extremities at multiple levels. So, if a multiple level study can be evaluation of segmental blood pressure measurements, segmental Doppler waveform analysis, segmental volume plethysmography, segmental transcutaneous oxygen tension measurements, measurements with postural provocative tests and/or measurements with reactive hyperemia. So, here majorly the segmental pressure measurement gets included with CPT code 93923. Same goes with upper extremities. And when both the Upper and Lower extremities are evaluated we will use twice 93923 along with 59 or XS modifier depending on the client coding guideline.

When to use CPT code 93923 and 93922

First of all just check the report for Ankle brachial Index (ABI). If it is done then look for the procedure codes description for code 93923 and 93922. Now check the documentation of the report and search for the presence of segmental pressure in the report. If the report documents the segmental pressure, we can go ahead and code CPT code 93923 and if not we will code 93922. I generally look for these things if I have to code any of these CPT codes. However, the more you come across such reports, the more your concepts become clear. So, do check the report properly before using CPT code 93922 and  93923.
