Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93503 covers

A physician places a flow-directed catheter, commonly a Swan-Ganz catheter, through venous access and advances it through the right heart into the pulmonary artery for hemodynamic monitoring. The service is typically performed in an intensive care unit, operating room, or cardiac catheterization setting by a cardiologist, anesthesiologist, or other physician managing a patient who needs invasive monitoring. The purpose is catheter placement and monitoring, not a diagnostic right-heart catheterization study.

Report the service when the record supports placement of the monitoring catheter, including the indication and the catheter’s final position. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate because the descriptor and anatomy do not support bilateral reporting. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
