Unfortunately, there really isn't enough information here for me to give a solid, exact answer. Basically, I'd need to know: Was the biopsy performed open or laparoscopic? Was it a needle biopsy? Was the entire mass removed? What kind of cells did they find?
I asked General Surgery Coding Alert consulting editor, Marcella Bucknam, to weigh in and she said: "One would expect liver tissue considering the area so I’m inclined toward code 47001. But there’s no way for me to know for sure. The coder should probably talk to the surgeon if that’s possible. Sometimes biopsies don’t return the kind of result we think they will even when the surgeon is pretty sure what he’s seeing. If he’s really sure it was a lymph node, she would need to use the unlisted lymph code depending on whether it was done open (38589) or lap (38589)."
I hope that helps you get started. Good luck!
