What is the CPT® code for lung shunt fraction liver mapping? Here is part of the documentation below. There is more detail in the report but these lung shunt fraction studies for hepatic masses seem to be common.

Patient received 5.2 MCI Technetium 99M MAA. Multiple static views of the lungs and abdomen were obtained. The geometric mean of the lungs and liver were obtained. The lung shunt fraction was obtained.


The current recommendation is to report the following code:

78801 Radiopharmaceutical localization of tumor or distribution of radiopharmaceutical agent(s); multiple areas

As you can see, the code description allows for imaging of more than tumors. Because two areas (chest and abdomen) are imaged, this would be the appropriate code in your scenario.
