Automatic Implantable Cardioverter Defibrillator (AICD)
The Automatic Implantable Cardioverter Defibrillator (AICD) is a device designed to monitor a patient's heart rate, recognize ventricular fibrillation or ventricular tachycardia, and deliver an electric shock to terminate these arrhythmias in order to reduce the risk of sudden death.
Indications for AICD implantation can be broadly subdivided into 1) secondary prevention; i.e., their use in patients who have experienced a potentially life-threatening episode of ventricular tachyarrhythmia; and 2) primary prevention; i.e., their use in patients who are considered at high risk for sudden cardiac death but who not yet experienced life-threatening ventricular tachycardia (VT) or ventricular fibrillation (VF).
The standard ICD involves placement of a generator in the subcutaneous tissue of the chest wall. Transvenous leads are attached to the generator and threaded intravenously into the endocardium. The leads sense and transmit information on cardiac rhythm to the generator, which analyzes the rhythm information and produces an electrical shock when a malignant arrhythmia is recognized.
A totally subcutaneous ICD (S-ICD®) has also been developed. This device does not employ transvenous leads and thus avoids the need for venous access and complications associated with the venous leads. Rather, the S-ICD® uses a subcutaneous electrode that is implanted adjacent to the left sternum. The electrodes sense the cardiac rhythm and deliver countershocks through the subcutaneous tissue of the chest wall.
Several automatic implantable cardioverter defibrillators are approvedby the U.S. Food and Drug Administration (FDA) through the premarket application approval process. FDA-labeled indications generally include patients who have experienced life-threatening ventricular tachyarrhythmia associated with cardiac arrest or ventricular tachyarrhythmia associated with hemodynamic compromise and resistance to pharmacologic treatment. Devices manufactured by Guidant are approved by the FDA for use in "patients at high risk of sudden cardiac death due to ventricular arrhythmias and who have experienced at least one of the following: an episode of cardiac arrest (manifested by the loss of consciousness) due to a ventricular tachyarrhythmia; recurrent, poorly tolerated sustained ventricular tachycardia (VT); or a prior myocardial infarction, left ventricular ejection fraction of less than or equal to 35%, and a documented episode of nonsustained ventricualr tachycardia (VT), with an inducible ventricular tachyarrhythmia." On July 18, 2002, the FDA expanded the approved indications for the Guidant AICD devices to include the prophylactic use of Guidant ICDs for cardiac patients who have had a previous heart attack and have an ejection fraction that is less than or equal to 30%. This expanded indication is based on the results of the MADIT II trial. Medtronic devices are approved "to provide ventricular antitachycardia pacing and ventricular defibrillation for automated treatment of life-threatening ventricular arrhythmias." Other devices have approval language similar to Medtronic.
On September 28, 2012, the S-ICD® system by Cameron Health, Inc. was approved by FDA “to provide defibrillation therapy for the treatment of life-threatening ventricular tachyarrhythmias in patients who do not have symptomatic bradycardia, continual (incessant) ventricular tachycardia, or spontaneous frequently recurring ventricular tachycardia that is reliably terminated with anti-tachycardia pacing.”
NOTE: AICDs may be combined with other pacing devices, such as pacemakers for atrial fibrillation, or biventricular pacemakers designed to treat congestive heart failure. This policy addresses AICDs alone, when used solely to treat patients at risk for ventricular arrhythmias.

The use of the automatic implantable cardioverter defibrillator (AICD) may be considered medically necessary in adults who meet the following criteria:
The use of the AICD is considered investigational in primary prevention patients who:
The use of the ICD may be considered medically necessary in children who meet any of the following criteria:
The use of the ICD is considered investigational for all other indications in pediatric patients.
The use of a subcutaneous ICD is considered investigational for all indications in adult and pediatric patients.
Federal Employee Program (FEP) may dictate that all FDA-approved devices, drugs or biologics may not be considered investigational and thus these devices may be assessed only on the basis of their medical necessity.
Investigative service is defined as the use of any treatment procedure, facility, equipment, drug, device, or supply not yet recognized by certifying boards and/or approving or licensing agencies or published peer review criteria as standard, effective medical practice for the treatment of the condition being treated and as such therefore is not considered medically necessary.
The coverage guidelines outlined in the Medical Policy Manual should not be used in lieu of the Member's specific benefit plan language.

08/23/2011: Policy statement revised to clarify the indications in ischemic cardiomyopathy, with separate indications for class II/III and class I patients. Policy statement regarding waiting time in nonischemic cardiomyopathy was revised to remove the specification of a 9-month waiting period. Added policy statement to outline coverage criteria for ICD in pediatric patients.
01/09/2013: Added policy statement to indicate that the use of a subcutaneous ICD is considered investigational for all indications in adult and pediatric patients. Added 0319T - 0328T to the Code Reference section as non-covered.
05/06/2013: Added ICD-9 codes 414.8, 425.4, and V12.53 to the Covered Codes table.
12/13/2013: Policy reviewed; no changes.
03/19/2014: Policy reviewed; no changes.
05/07/2014: Policy reviewed; description updated regarding standard and subcutaneous ICDs. Moved the first medically necessary policy statement under the adults section and replaced the word "patients" with "adults." Deleted the word "symptomatic" from the statement in the primary prevention criteria. It previously stated: Symptomatic nonischemic dilated cardiomyopathy and left ventricular ejection fraction of 35% or less, after reversible causes have been excluded, and the response to optimal medical therapy has been adequately determined. Added "after reversible causes (eg, acute ischemia) have been excluded" to the policy statement on secondary prevention in adults.
