My provider did a laparoscopic cholecystectomy with grams and a common bile duct exploration with removal of a stone. The provider also had to do a choledochorraphy due to an absence of viable cystic duct for routine closure due to extensive necrosis of the distal gallbladder infundibulum region. I am trying to determine the correct codes to use. I am thinking the 47564 would work for the lap chole w/grams and cbd explore but what would I use for the choledochorraphy? Thanks for your help!
