Ask Dr. Z

How do you recommend coding an ultrasound guided drainage of an anterior abdominal wall seroma? I found a Q&A from 2008 about a breast seroma where you recommmended 10160 & 76942. Our physician inserted a Yueh sheath then a wire and drainage catheter w/holes. He removed 3300ML of fluid then kneaded, palpated, and compressed the abdominal wall to eliminate all fluid. Ultrasound revealed no remaining fluid. The catheter was attached to JP bulb suction and abdominal binder was applied. We're leaning toward unlisted codes 49999 & 76492 because it isn't an abscess (10160) and it isn't an open drainage (10140) and would appreciate your opinion. Oh, the seroma doesn't appear to be infected - if that helps at all. Thank you.
