Hello,
Look into these codes:
33285-33286
The physician implants or removes an electronic device that is capable of recording heartrates and rhythms for over one year (subcutaneous cardiac rhythm monitor, cardiac event recorder, implantable loop recorder or ILR). In 33285, the physician uses a scalpel to make a small parasternal incision and dissects down to the level of subcutaneous tissue located over the left pectoral or mammary area. The monitor is implanted into the subcutaneous tissue. Electrodes that sense heart activity are located on the surface of the monitor, making it unnecessary to place transvenous leads. The device continuously and automatically monitors the heart's electrical activity when sensing the patient's rapid, irregular, or slow heartrate or can also be prompted by the patient in the course of experiencing symptoms. Programming of the device is included in this service. In 33286, the physician removes the monitor when sufficient information regarding the heart's activities has been obtained or when the batteries run out by incising down to the level of the recorder and removing it. In either surgery, the incision is closed with sutures. This type of recorder is capable of storing many separate events. When appropriate, a programmer is used by the physician to retrieve the information that can be displayed, stored, or printed.
