What is the proper code when doing an ultrasound scan of a “bump” or “small rounded mass” on the back that is felt through the skin?
According to the American College of Radiology’s (ACR) Ultrasound Coding User’s Guide, a soft tissue scan of the upper back is 76604-52. The lower back is 76705. Modifier -52 indicates reduced services.
76604 Ultrasound, chest (includes mediastinum), real time with image documentation
76705 Ultrasound, abdominal, real time with image documentation; limited (e.g., single organ, quadrant, follow-up)
