Displacement of bile duct prosthesis, initial encounter

This code signifies the dislodgement or movement of a prosthetic device, such as a stent, that was surgically placed within a bile duct. This displacement can lead to impaired bile flow, obstruction, or other complications related to the biliary system. It specifically refers to the initial presentation or treatment for this particular complication.

Apply this code when a patient presents for the first time with symptoms or findings indicating that a previously implanted bile duct prosthesis has moved from its intended position. This would include scenarios where imaging confirms stent migration or dislodgement requiring intervention. It is used for the initial encounter for the management of this specific complication.

• Ensure documentation clearly states the displacement of a bile duct prosthesis, not another type of prosthesis.
• Confirm this is the initial encounter for the treatment of this displacement; subsequent encounters would use a different seventh character.
• Look for supporting documentation such as imaging reports (e.g., ERCP, MRCP) confirming the displacement.
