Breakdown of unsp cardiac electronic device, sequela

This code signifies a long-term complication arising from a mechanical failure of an unspecified cardiac electronic device, such as a pacemaker or defibrillator. It indicates that the initial breakdown event has already occurred and the patient is now experiencing residual effects or conditions directly attributable to that past mechanical failure.

This code is appropriate for encounters where the patient is being treated for a current condition that is a direct consequence of a previously resolved or managed mechanical breakdown of an implanted cardiac device. It should be used when the acute phase of the device malfunction is over, and the focus is on the sequelae.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past mechanical breakdown of a cardiac device.
• Do not use for initial or acute mechanical breakdowns; those require codes from the initial or subsequent encounter categories.
