What 93355 covers

During a transcatheter structural heart procedure, a cardiologist with echocardiography expertise uses an esophageal probe to guide device placement and assess the result in real time. Common settings include a catheterization laboratory or hybrid operating room for procedures such as transcatheter aortic valve replacement, transcatheter mitral repair, or left atrial appendage closure. The service includes image acquisition, interpretation, reporting, and real-time 3D imaging; it is not the catheter-based repair or implantation itself.

Report 93355 for TEE performed to guide the transcatheter intervention. Documentation should identify the intervention, describe the imaging used to guide it, and record relevant anatomy, device position, findings, and the interpretation. Distinguish procedural guidance from a diagnostic TEE performed to evaluate a clinical question and from TEE during open cardiac surgery. CMS physician fee schedule valuation includes physician work, practice expense, and malpractice RVUs.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

No. It represents the TEE guidance service, not the valve repair, device closure, or other catheter-based intervention.

Is real-time 3D imaging part of 93355?

Yes. The service includes real-time 3D imaging, along with image acquisition, interpretation, and reporting.

What documentation supports reporting 93355?
