An exam is ordered for CT study of the sacroiliac (SI) joints, with and without contrast, with an indication of SI joint pain. SI joints are studied, and findings documented for both joints. Should this be coded with 76380, as we are only studying a limited portion of the pelvis?
Use code 72194—computed tomography, pelvis; without contrast material, followed by contrast material(s) and further sections. 72194 is the correct choice instead of 76380 for this exam because the indication is specific to the study of the SI joint(s) and they are completely studied and fully documented.
