Cardiac catheterization
About 93503: Flow-directed pulmonary artery catheter placement
Reports placement of a flow-directed catheter in the pulmonary artery for hemodynamic monitoring, such as in an intensive care or operative setting.
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.

93503 billing questions
How is this different from a diagnostic right-heart catheterization?
This code describes placing a flow-directed catheter for monitoring. A diagnostic right-heart catheterization, such as 93451, is selected when the physician performs a diagnostic hemodynamic study.
Does the record need to identify the catheter’s final position?
Yes. Document the monitoring indication, the placement procedure, and the catheter’s final position in the pulmonary artery.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code because the descriptor and anatomy do not support bilateral reporting.
Can an assistant-at-surgery be paid?
Assistant-at-surgery payment is allowed only when the record documents medical necessity. CMS does not permit co-surgeons or team surgery for this code.
What care is included in the global period?
The 0-day global period includes same-day preoperative and postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
