What 93453 covers
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.

How to choose
- 93451Right heart cathHemodynamic measurements
- Use 93451 for right-heart catheterization alone. Report 93453 when the diagnostic study also includes left-heart catheterization and left ventriculography.
- 93452Left heart cathLeft-sided study
- 93452 covers left-heart catheterization with ventriculography. The right-heart catheterization is the distinguishing service in 93453.
- 93460Heart catheterizationRight and left heart with coronary imaging
- 93460 includes coronary angiography with the combined right- and left-heart study and ventriculography. Use 93453 when coronary angiography is not part of the study.
- 93458Coronary catheterizationLeft heart, native coronaries
- 93458 includes left-heart catheterization, coronary angiography, and ventriculography, but not right-heart catheterization. 93453 includes right-heart catheterization and does not represent coronary angiography.
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 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.
