What 93452 covers
A cardiologist typically advances a catheter through arterial access into the left side of the heart to assess pressures and cardiac function. The study may include contrast injection to image the left ventricle; this is used in evaluations such as suspected valve disease or impaired ventricular function. It is commonly performed in a cardiac catheterization laboratory. Coronary angiography is not part of this service; when it is also performed, a different code describes the combined work.
Report the code for the left-sided catheter study, whether or not ventriculography is performed. The record should support the catheterization and document the findings and any imaging performed. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and no modifier represents the global service. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeon and team-surgery billing are not permitted.

How to choose
- 93453Heart catheterization
- 93453 includes both right- and left-heart catheterization. Use 93452 when the reported study is limited to the left heart.
- 93458Coronary catheterization
- 93458 includes coronary angiography with the left-heart catheterization. Choose 93452 when coronary angiography was not performed.
- 93454Coronary angiography
- 93454 describes coronary angiography without left-heart catheterization. It does not replace 93452 when a left-sided catheter study is performed.
- 93451Right heart cath
- 93451 is for right-heart catheterization alone; 93452 is for the left-heart study.
93452 billing questions
When should 93452 be used instead of 93458?
Use 93452 for the left heart catheterization without coronary angiography. When coronary angiography is also performed, 93458 describes the combined service.
Does 93452 require ventriculography?
No. Ventricular imaging may be performed as part of the study, but the code can be reported when ventriculography is not performed.
How are the professional and technical components billed?
Use modifier 26 for the professional interpretation and modifier TC for the technical component. Billing without either modifier represents the global service.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code and anatomy.
How does the multiple-procedure rule affect payment?
For procedures performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%. Same-day preoperative and postoperative care is included in this code's 0-day global period.
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.
