Breakdown (mechanical) of cardiac electronic device, init

This code signifies a mechanical malfunction or failure of an implanted cardiac electronic device other than a pacemaker or defibrillator. This could involve issues such as lead fracture, dislodgement, or component failure of devices like cardiac resynchronization therapy (CRT) devices or implantable loop recorders (ILRs). The "initial encounter" designation indicates that this is the first time the patient is being seen for this specific complication.

Use this code when a patient presents with symptoms or findings directly attributable to a mechanical breakdown of an implanted cardiac electronic device (excluding pacemakers and defibrillators), and this is the initial visit for the problem. Examples include a patient experiencing symptoms due to a fractured lead of their CRT device or a non-functioning ILR due to internal component failure.

• Always assign a secondary code to specify the type of cardiac electronic device involved (e.g., Z95.811 for cardiac resynchronization therapy device).
• Ensure documentation clearly states a "mechanical breakdown" rather than an infection or other complication type.
• Verify that this is indeed the "initial encounter" for this specific mechanical breakdown; subsequent encounters would use a different seventh character.
