Breakdown (mechanical) of indwelling ureteral stent, init

This code signifies a mechanical failure or structural compromise of an indwelling ureteral stent, such as a fracture, kinking, or material degradation. It indicates that the stent itself has malfunctioned, rather than a problem with its placement or a biological reaction. This initial encounter designation applies when the patient is first presenting for this specific issue.

Apply this code when documentation clearly states a mechanical breakdown of an existing ureteral stent, leading to symptoms or requiring intervention. This would include situations where imaging reveals stent fragmentation, migration due to structural failure, or a kink preventing proper drainage. It is used for the initial visit where this breakdown is identified and addressed.

• Ensure documentation specifies "breakdown" or "mechanical failure" of the stent, not just a malposition or obstruction from other causes.
• Verify that this is the initial encounter for this specific stent breakdown; subsequent encounters would use the appropriate follow-up or sequela character.
• Always code the underlying reason for the ureteral stent placement if it is still relevant and being treated.
