Breakdown (mechanical) of bile duct prosthesis, sequela

This code signifies a mechanical failure of a previously implanted bile duct prosthesis, such as a stent or shunt, that is causing current symptoms or requiring intervention. This breakdown can involve fracturing, dislodgement, or other structural compromises of the device. It indicates a long-term complication arising from the initial prosthetic placement.

Use this code when documenting a patient presenting with issues directly attributable to the mechanical failure of a bile duct prosthesis, even if the initial implantation occurred in the distant past. This applies to situations where the breakdown is causing obstruction, leakage, or other adverse effects. It is appropriate for follow-up care related to the failed device.

• Always sequence this code after the primary diagnosis describing the specific complication resulting from the breakdown (e.g., biliary obstruction).
• Ensure documentation clearly specifies "mechanical breakdown" of the bile duct prosthesis, not just a general malfunction.
• This "S" seventh character indicates a sequela, meaning it's used for complications or conditions that arise as a direct result of an earlier injury or disease.
