DESCRIPTION OF PROCEDURE: Risks and benefits were explained to the patient and informed consent was obtained. The procedure was
done in the endoscopy suite with the assistance of Dr. X for the rendezvous procedure with a previously placed percutaneous stent and wire, which was extended transhepatic into the common bile duct and grabbed with a snare through the
sphincterotome. Cholangiogram showed a large proximal biliary stone in the area of bifurcation. A 1-cm sphincterotomy was done
and the duct was swept with 10- to 12-mm biliary balloon, with extraction of a proximal obstructive stone. At the end of the case, occlusion cholangiogram did not show any additional filling defect with a clean common bile duct otherwise.

IMPRESSION: Status post sphincterotomy and extraction of a large obstructive biliary stone."

For the above scenario what will be the CPT codes?
