Medical and Nursing Specialists, Physicians, and Physician Assistants Handbook : 9 Physician : 9.2 Services, Benefits, Limitations, and Prior Authorization : 9.2.76 Wearable Cardiac Defibrillator (WCD) : Prior Authorization for WCD
Prior authorization is required for the rental of WCD (procedure code K0606).
The WCD may be prior authorized for clients at high-risk of sudden cardiac arrest who meets one of the following criteria:
Has completed electrophysiologic studies to determine the type of arrhythmia present and confirm that a wearable cardiac defibrillator is the best course of treatment.
Has a familial or inherited condition with a high risk of life-threatening ventricular tachyarrhythmias, such as long QT syndrome or hypertrophic cardiomyopathy.
Has had either documented prior myocardial infarction or dilated cardiomyopathy and a measured left ventricular ejection fraction (LVEF) less than or equal to 35 percent.
Clinically inducible hemodynamically significant ventricular tachycardia (HSVT) or ventricular fibrillation (VF), where drug treatment has been ineffective, or the side effects of the medication used to treat the arrhythmia are intolerable.
Specific ST-T wave changes, borderline CPK-MB isoenzymes, and dangerous ventricular arrhythmias are exhibited in a postmyocardial infarction patient.
Recurrent syncope of undetermined etiology in a patient with HSVT or VF induced by EPS in whom no effective or tolerated drug is available or appropriate. Symptoms must be linked to HSVT or VF.
The WCD is contraindicated in clients with an active ICD and should not be used in clients who meet the following criteria:
The WCD is considered investigational and not medically necessary for all other indications, including but not limited to, the following:
Clients in whom a reversible triggering factor for VT/VF can be definitely identified, such as ventricular tachyarrhythmias in evolving acute myocardial infarction or electrolyte abnormalities.
A completed Home Health Services (Title XIX) Durable Medical Equipment (DME)/Medical Supplies Physician Order Form (Title XIX Form) prescribing the DME and/or medical supplies must be signed and dated by the prescribing physician familiar with the client prior to requesting authorization.
The completed Title XIX Form must be maintained by the requesting provider and the prescribing physician. The original signature copy must be kept in the physician’s medical record for the client.
To complete the prior authorization process the provider must submit the completed Title XIX Form by fax to the Home Health Unit at 1-512-514-4209 or in writing to the following address:

When a WCD is not covered as a home health service, it may be considered for reimbursement through the CCP for clients who are 20 years of age and younger. All of the following criteria must be met for CCP reimbursement for a WCD:
Rental of an automatic external defibrillator, with integrated electrocardiogram analysis, garment type (procedure code K0606) may be prior authorized (initially for up to three months) with documentation supporting the medical necessity and appropriateness of the device.
The provider may be reimbursed only for the length of time the device is used even though the authorization for the rental may be for a longer period of time.
The rental of the device includes the monitor, electrode belt (four sensors or electrodes and three treatment pads), garment, two rechargeable batteries, a battery charger and modem.
The purchase of a replacement battery (procedure code K0607), the purchase of a garment (procedure code K0608), and electrodes (procedure code K0609) will be considered part of the rental.
Prior authorization extensions for WCDs beyond the initial three-month rental may be considered by the medical director when documentation supports continued medical necessity for the device. Providers must submit new documentation to support continued medical necessity for an extension of the rental to be considered.
To avoid unnecessary denials, the physician must provide correct and complete information, including documentation for medical necessity of the device. The physician must maintain documentation of medical necessity in the client’s medical record. The requesting provider may be asked for additional information to clarify or complete a request for the WCD.
Retrospective review may be performed to ensure documentation supports the medical necessity of the service when billing the claim.
