I'm not sure which would be best way to bill this. Dr did diagnostic laparoscopy with wedge resection of liver lesion which was sent for path confirming metastatic ca. He then converted to open procedure and did a partial gastrectomy. My question is which would be best, an unlisted laparoscopic code 47379 or exploratory laparoscopy with biopsy 49321? I'm leaning towards the unlisted code but those can be difficult to bill some times. Patient has private bcbs.
