TO 3D OR NOT TO 3D W
hile the 3D procedures codes 76376 and 76377 have existed for a number of years, questions still arise as to their appropriate application. The answer depends upon the modality, whether a code exists that includes 3D by definition and/or if the documentation and medical necessity requirements are met. Let’s address the question as to whether or not the 3D codes may be assigned in addition to the base study by modality. Regular diagnostic studies: No. According to CPT Assistant (September 2019) 76376 is only applicable to advanced 3D rendering performed for the imaging modalities included in the code descriptors (CT, MRI, 56

ultrasound or other tomographic modality). The use of the 3D codes necessitates 3D post-processing for advanced visualization and volumetric assessment derived from 2D tomographic images. Ultrasound: Yes. Code 76376 is used when 3D rendering is performed on the ultrasound console, and 76377 is used when 3D rendering is performed on an independent workstation (e.g., PACS workstation). The 3D rendering code should be reported in addition to the code for the ultrasound exam. The most frequently encountered studies are OB ultrasounds and breast ultrasound utilizing Automated Breast Ultrasound System (ABUS) technology. Mammography: No. Tomosynthesis is sometimes incorrectly referred to as 3D but it is a different technology. There are codes for breast tomosynethesis that should be ADVANCING THE IMAGING PROFESSIONAL
