In this procedure, the provider performs imaging supervision and interpretation for a separately reportable biliary duct dilation. The provider X–rays the bile ducts during insertion of a catheter or camera, called an endoscope, into the ducts. He administers contrast and then views the duct contents with an X–ray camera called a fluoroscope. The X–ray identifies a narrowing or other abnormality of the biliary tract and then helps the provider to dilate the stricture with a balloon and possibly place a biliary stent to prevent the stricture from reoccurring. Report this code to represent only imaging supervision and interpretation for this procedure.
