Radiology Question for the Week of July 4, 2016


When billing CPT 78608 for dementia, is modifier PI or PS required?


No, modifiers PI and PS are used on claims for positron emission tomography (PET) for oncologic indications only. If a brain PET is performed for dementia, modifiers PI or PS would not be applied to code 78608 (brain imaging, PET; metabolic evaluation). If a brain PET is performed for cancer, then PI or PS would be required with 78608.
