Summary & Overview
HCPCS K0606: Wearable Automatic External Defibrillator, Garment Type
HCPCS Level II code K0606 identifies a garment-type automatic external defibrillator with integrated electrocardiogram analysis — a wearable durable medical device that monitors heart rhythm and can deliver defibrillation when indicated. This code matters nationally because wearable defibrillators are used for ambulatory patients at elevated risk of sudden cardiac arrest, bridging gaps in clinical management and impacting durable medical equipment coverage and utilization across payers.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise overview of the device and clinical context, typical sites of service (outpatient and home), payer coverage patterns and benchmarks where available, common billing and documentation considerations, and relevant policy updates that affect claims processing for garment-type wearable defibrillators. The summary also highlights areas where data was not provided in the input and directs readers to expected items for operational workflows, such as expected service lines and associated billing components.
This publication is intended to provide payers, billing professionals, and clinical program managers with a national-level briefing on HCPCS Level II code K0606, its clinical role, and the major administrative themes that influence coverage and billing for wearable defibrillator garments.
Billing Code Overview
HCPCS Level II code K0606 describes an automatic external defibrillator, with integrated electrocardiogram analysis, garment type. This device is a wearable garment that continuously or intermittently monitors cardiac rhythm and delivers defibrillation therapy as indicated by integrated ECG analysis.
-
Service type: Durable medical equipment (wearable defibrillator/monitoring device)
-
Typical site of service: Outpatient or home use where patients require ambulatory cardiac monitoring and potential external defibrillation capability for arrhythmia management or sudden cardiac arrest risk
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a high risk of sudden cardiac arrest due to recurrent ventricular arrhythmias or structural heart disease who requires a wearable, garment-type automatic external defibrillator with integrated ECG analysis for continuous monitoring and rescue therapy. The device is fitted in a cardiology or electrophysiology clinic after a consult that documents indications (e.g., recent myocardial infarction with reduced ejection fraction, awaiting implantable cardioverter-defibrillator placement, or transient contraindication to implanted devices). The workflow includes device selection and sizing, baseline 12-lead ECG review, patient education on wear and maintenance, documentation of device serial number and durability, insurance prior authorization when required, dispensing the device with written instructions, and scheduled follow-up visits for data download, wound check if applicable, or transition to a permanent implant when clinically indicated. Typical sites of service are outpatient cardiology or electrophysiology clinics, device-dispensing centers, and occasionally emergency departments for immediate post-event fitting.
