External Defibrillator Vest
This patient had an implantable cardioverter/defibrillator (ICD) placed in 1988. In 2004, the ICD was relocated to the subpectoral location. The patient now presents with an ICD infection. The device and leads were removed at hospital A and the patient was transferred to hospital B for IV antibiotics. At hospital B, the patient was fitted with an automatic external defibrillator to protect her upon discharge from the facility. The physician documented that a “life vest external defibrillator†was fitted and patient given instructions and training completed. The ICD device will be reimplanted at a later date. Is there a specific ICD-9-CM code for the external defibrillator vest, or should code 99.62, Other electric countershock of heart, be assigned? ...

Article Overview
This premium article discusses how a temporary wearable external defibrillator is handled in a specific coding scenario involving device infection, removal, transfer of care, and later reimplantation. It is intended for coders, billers, and compliance staff who need to understand whether a separate procedure code is reported for the fitting of the external vest and how the encounter is framed in ICD-9-CM-based guidance. The article focuses on the documentation context, the coding question presented, and the resulting coding direction.
Why This Topic Matters
Temporary cardiac device management can create uncertainty in procedure coding, especially when patients are discharged with protective equipment after device removal. Correctly understanding the coding guidance helps support accurate claims, consistent records, and compliant reporting.
