Memorize this definition to skip to the head of the coding class Before you report modifier -78, double-check that your procedure took place in an "operating room" (OR) as Medicare understands it:
"A place of service specifically equipped and staffed for the sole purpose of performing procedures. The term includes a cardiac catheterization suite, a laser suite, and an endoscopy suite. It does not include a patient's room, a minor treatment room, a recovery room, or an intensive care unit (unless the patient's condition was so critical there would be insufficient time for transportation to an OR)."
