What 93460 covers
A cardiologist typically performs this diagnostic catheterization in a cardiac catheterization laboratory to assess coronary anatomy and measure pressures in the right and left sides of the heart. The study can support evaluation of coronary artery disease, valve disease, pulmonary hypertension, or cardiomyopathy. It includes coronary angiographic imaging and left ventriculography when performed; the right- and left-heart measurements provide hemodynamic information that a coronary angiogram alone does not supply.
Select this code when the documented service includes both right- and left-heart catheterization and coronary angiography. The report should support the catheterization performed, the angiographic study, and the physician’s interpretation; bypass graft angiography points to a different code in this family. A 0-day global period includes same-day preoperative and postoperative care. The service may be billed globally or split into professional interpretation (modifier 26) and technical equipment and staff (modifier TC). When multiple procedures occur 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.

How to choose
- 93458Coronary catheterization
- Choose 93458 for left-heart catheterization with coronary angiography when a right-heart study is not performed. The combined right- and left-heart service supports 93460.
- 93461Heart catheterization
- 93461 includes bypass graft angiography with the combined heart catheterization and coronary study. Use 93460 when graft angiography is not part of the documented service.
- 93453Heart catheterization
- 93453 covers combined right- and left-heart catheterization with ventriculography but not coronary angiography. The coronary study distinguishes 93460.
- 93456Cardiac catheterization
- 93456 combines right-heart catheterization and coronary angiography but does not include the left-heart catheterization component represented by 93460.
93460 billing questions
When should this code be selected instead of 93458?
Use 93460 when the service includes right- and left-heart catheterization with coronary angiography. Code 93458 describes the left-heart and coronary study without the right-heart catheterization.
Is left ventriculography required?
The code includes left ventriculography when performed. The record should reflect what was actually done rather than implying a ventriculogram that was not obtained.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service; billing without either modifier represents the global service.
Can modifier 50 be used for this service?
No. The anatomy and service definition make bilateral adjustment inappropriate for this code.
How are additional procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others at 50%. The 0-day global period includes same-day preoperative and postoperative care.
What supports assistant-at-surgery payment?
The record must document medical necessity for the assistant. Co-surgeons and team surgery are not permitted for this code.
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.
