Breakdown (mechanical) of artificial heart, subs encntr

This code signifies a mechanical failure or malfunction of a previously implanted artificial heart, occurring during a follow-up visit or subsequent treatment period. It indicates that the device itself is no longer functioning as intended due to a structural or operational issue, rather than an infection or other complication.

Apply this code when a patient presents for evaluation or treatment of a mechanical breakdown of their artificial heart, such as a pump failure, valve malfunction, or structural integrity issue, after the initial treatment for the implant. This would be used for readmissions or outpatient visits related to the device's mechanical failure.

• Ensure documentation clearly specifies a mechanical breakdown of the artificial heart, not another type of complication.
• Confirm the encounter is for subsequent care, not the initial treatment of the breakdown (which would use an A or D seventh character).
• Verify the device is explicitly an "artificial heart" and not another type of cardiac assist device.
