Breakdown of cardiac and vascular devices and implants, init

This code signifies a mechanical failure or malfunction of a cardiac or vascular device, other than a cardiac pacemaker, defibrillator, or heart valve prosthesis. This breakdown is due to a structural issue with the device itself, not an infection or physiological complication.

Use this code when a patient presents with symptoms directly attributable to the mechanical failure of an implanted cardiac or vascular device, such as a stent, vascular graft, or ventricular assist device (VAD), during the initial treatment for this specific complication. This applies to situations requiring assessment, repair, or replacement of the faulty device.

• Ensure the documentation clearly specifies a mechanical breakdown of the device, not an infection or other complication.
• Confirm the device involved is not a pacemaker, defibrillator, or heart valve, as those have more specific codes.
• The "A" seventh character indicates an initial encounter for the treatment of this specific breakdown.
