Question:
We are coding for a professional client and came across a CTA report that clearly states the 3D reconstruction was NOT supervised by the radiologist. Can you please clarify whether supervision of the 3D reconstruction is a required element of CPT 71275? Sample section of the report below. Thank you so much!
Report Sample –
Imaging Protocol: Computed tomographic angiography of the chest with contrast.
3D rendering (not supervised by radiologist): MIP and/or 3D reconstructed images were created by the technologist.
Radiation Optimization: All CT scans at this facility use at least one of these dose optimization techniques: automated exposure control; mA and/or kV adjustment per patient size (includes targeted exams where dose is matched to clinical indication); or iterative reconstruction.
Contrast material: Isovue 370
Contrast volume: 100 ml
Contrast route: Intravenous
Answer:
While CTA codes require 3D post-processing to allow coding as a CTA, there is not the same requirement of “under concurrent supervision” that CPT code 76376 or 76377 demands.
We would code as a CTA based upon the information you have presented.
