What 93454 covers

This service uses catheter-based contrast injections and imaging to assess the native coronary arteries. A cardiologist, commonly one performing diagnostic or interventional cardiac procedures, typically performs it in a cardiac catheterization laboratory. The study supports evaluation of suspected or known coronary artery disease, such as in a patient with symptoms or other findings that warrant anatomic assessment. It includes the imaging supervision and interpretation for the coronary study.

Select 93454 when the documented service is coronary angiography without bypass-graft imaging or left-heart catheterization; use a different code when those additional services are performed. The report should support the catheter and injection work, the coronary images obtained, and the physician’s interpretation. The 0-day global period includes same-day preoperative and postoperative care. Modifier 26 identifies the professional interpretation, modifier TC the technical service, and no modifier the global service. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

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.

93454 billing questions

When should 93455 be used instead?

Use 93455 when the coronary study includes catheter placement in bypass grafts and graft angiography. Code 93454 describes the coronary study without graft imaging.

How does 93454 differ from 93458?

93454 reports coronary angiography without left-heart catheterization. When coronary angiography and left-heart catheterization are performed together, 93458 is the relevant combined code.

Can the professional and technical portions be billed separately?

Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Billing without either modifier represents the global service.

Is the interpretation separately reported?

The imaging supervision and interpretation are part of the coronary angiography service. Modifier 26 identifies that professional component when it is billed separately from the technical component.

Can modifier 50 be used for imaging both coronary arteries?

No. The CMS bilateral adjustment does not support modifier 50 for this service; the coronary anatomy and descriptor make that modifier inappropriate.

What happens when other procedures are performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. Any assistant-at-surgery payment requires documentation of medical necessity.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
