Breakdown (mechanical) of cardiac electronic device, sequela

This code signifies a mechanical failure or malfunction of a cardiac electronic device other than a pacemaker or defibrillator, occurring as a sequela. This could involve devices like cardiac resynchronization therapy (CRT) devices or implantable loop recorders (ILRs), where a component has physically broken down or ceased to function properly due to a mechanical issue. The "sequela" designation indicates that this is a late effect or complication of the initial device implantation.

Use this code when documenting a patient presenting with symptoms or findings directly attributable to a mechanical breakdown of an implanted cardiac electronic device (excluding pacemakers/defibrillators), where the breakdown is not an acute event but a long-term complication. This applies to situations requiring device revision, repair, or replacement due to a mechanical issue that has manifested over time.

• Ensure the documentation clearly specifies a mechanical breakdown, not an electrical or software malfunction.
• Verify the device type is not a pacemaker or defibrillator, as those have specific codes.
• Confirm the "sequela" aspect, indicating a delayed or long-term complication rather than an acute post-procedural event.
