Cardiology
About 93453: Combined heart catheterization with ventriculography
Reports right- and left-sided cardiac catheterization with left ventricular imaging when the diagnostic study does not include coronary angiography.
An interventional cardiologist typically performs this diagnostic study in a cardiac catheterization laboratory. Catheters are used to assess pressures and other hemodynamic findings in the right and left sides of the heart, with contrast imaging of the left ventricle. The code represents the combined study; it is not the choice when the service also includes coronary angiography.
The record should support catheterization of both sides of the heart and the left ventriculography, including the relevant findings and interpretation. The service has a 0-day global period, so same-day preoperative and postoperative care is included. It may be billed globally or as the professional interpretation with modifier 26 or the technical service with modifier TC. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

93453 billing questions
How is this different from 93452?
93453 includes catheterization of both the right and left sides of the heart with left ventricular imaging. 93452 is the left-sided study with ventriculography, without the right-heart catheterization.
Can this code be used when coronary angiography is performed?
No. When the combined right- and left-heart study includes coronary angiography, consider the applicable code such as 93460 or 93461, based on the angiographic services performed.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the professional interpretation or TC for the technical service. Without either modifier, the claim represents the global service.
What documentation supports reporting this code?
Document catheterization of both the right and left heart, the hemodynamic assessment, the left ventriculography, and the interpreting physician's findings.
Should modifier 50 be appended?
No. The service is not reported as a bilateral procedure, so modifier 50 is inappropriate.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others are paid at 50% when performed in the same session.
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.
