Ask Dr. Z

I'm having trouble figuring what exactly was done here. The heading says "Right chest port revision", and then goes on to say a right internal jugular venotomy was performed, but no mention of ultrasound guidance. Then, the existing right chest port was explanted and a new double-lumen Bard port was tunneled. The catheter was inserted through the new right internal jugular access site and then connected to the double lumen port. The port was anchored to the right chest wall and flushed and aspirated appropriately. The impression says "Successful removal of a single lumen right chest port with placement of a new double-lumen port." Would this be coded 36582?
