What 93458 covers
An interventional cardiologist typically performs this diagnostic study in a cardiac catheterization laboratory. Catheters are advanced to the left side of the heart and into the coronary arteries to obtain hemodynamic information and images of the native vessels. Contrast imaging of the left ventricle may also be performed as part of the study. This code is used for the combined left-heart and coronary evaluation, rather than coronary imaging alone or a study that also includes right-heart catheterization.
Report the code when both left heart catheterization and coronary angiography are performed; document the catheterization, vessels imaged, and any ventriculography performed. The global service includes the professional interpretation and the technical resources; modifier 26 identifies the professional interpretation, and modifier TC identifies equipment and staff. Same-day preoperative and postoperative care is included in its 0-day global period. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is not appropriate for this left-sided study. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

93458 billing questions
When should 93458 be chosen instead of 93454?
Use 93458 when the service includes both left heart catheterization and coronary angiography. Code 93454 describes coronary angiography without the left heart catheterization component.
Is left ventriculography required to report 93458?
No. The code includes left ventriculography when performed, but the study may be reported when left ventriculography is not performed.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
Should modifier 50 be appended when both coronary arteries are imaged?
No. Report 93458 once for the described study; modifier 50 is inappropriate for this code.
How are other procedures in the same session affected?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple-procedure reduction. The code has a 0-day global period, which includes same-day preoperative and postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. 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.
