Cardiology procedure
About 33285: Subcutaneous cardiac rhythm monitor insertion
Report 33285 for placing and programming a subcutaneous cardiac rhythm monitor to detect intermittent arrhythmias not captured by shorter-term monitoring.
A cardiologist or electrophysiologist places a small rhythm-monitoring device beneath the skin, commonly in the chest, to record cardiac activity over an extended period. It is often used when a patient has unexplained syncope, intermittent palpitations, or suspected arrhythmia that has not been documented with shorter-term monitoring. The device is subcutaneous rather than a transvenous pacemaker or defibrillator system, and the service includes programming the monitor at insertion.
Report 33285 for the implantation service, supported by documentation of the indication, insertion, and device programming. Routine same-day preoperative and postoperative care is included in its 0-day global period. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to the others. Modifier 50 is inappropriate for this code. Medicare does not pay for an assistant at surgery, and co-surgeons and team surgery are not permitted.
