Internal Biliary Stent and Internal/External Biliary Drainage Catheter

Please note this question was answered in 2014. The coding advice may or may not be outdated.


Patient with jaundice presents for biliary evaluation. Physician performed: percutaneous transhepatic cholangiography (47500-59, 74320-59), cholangioplasty with stent placement (47556, 74363), and internal/external drainage catheter placement at the initial presentation. Would you please give us your insight on why the drainage catheter (47511, 75982) is not coded in addition to ductal dilation with or without stenting when the procedure was not staged?
