Question:

What is meant by the term, “independent workstation,” in the descriptors for CPT® codes 76376, 3D rendering with interpretation and reporting of computed tomography, magnetic resonance imaging, ultrasound, or other tomographic modality with image postprocessing under concurrent supervision; not requiring image postprocessing on an independent workstation, and 76377, 3D rendering with interpretation and reporting of computed tomography, magnetic resonance imaging, ultrasound, or other tomographic modality with image postprocessing under concurrent supervision; requiring image postprocessing on an independent workstation?

Answer:

“Independent workstation” refers to a separate computer or workstation used for the purpose of three-dimension (3D) reconstruction. Codes 76376 and 76377 were designed to capture two separate levels of physician work and practice expense in 3D rendering: code 76376 requires less physician work and code 76377 requires significantly more physician work. It is not appropriate to report code 76377 if 3D rendering occurs on the same workstation that processes 2D images; however, code 76376 would be appropriate in this situation.
