Presence of automatic (implantable) cardiac defibrillator

This code indicates that a patient has an automatic implantable cardioverter-defibrillator (AICD) device in place. This device is surgically implanted to monitor heart rhythm and deliver electrical shocks to correct life-threatening arrhythmias, such as ventricular tachycardia or fibrillation.

Apply this code when documenting the presence of an AICD in a patient's medical record. This is typically used for ongoing management, follow-up visits, or when the device's presence is relevant to the patient's current medical care, regardless of the reason for the encounter.

• This code is for the presence of the device, not its insertion or removal.
• Do not use this code if the patient has a pacemaker without defibrillator capabilities.
• Always code any associated cardiac conditions or reasons for the AICD implantation as primary or secondary diagnoses.
