Displacement of bile duct prosthesis, sequela

This code signifies a long-term complication where a previously placed prosthetic device within the bile duct has shifted from its intended position. This displacement can lead to various issues such as obstruction, cholangitis, or pain, and is considered a late effect of the initial procedure.

Apply this code when documentation clearly indicates that a bile duct prosthesis, such as a stent, has moved out of place, and the patient is presenting for evaluation or treatment of this specific sequela. This is appropriate for follow-up encounters addressing the chronic or residual effects of the displacement.

• Always ensure the documentation specifies "displacement" and not another type of mechanical complication (e.g., leakage, obstruction without displacement).
• This "S" code indicates a sequela, meaning it should be used for complications or conditions that are the late effects of the initial displacement.
• Code also any associated conditions or symptoms resulting from the displaced prosthesis, such as cholangitis (K83.01) or biliary obstruction (K83.1).
