What 93457 covers
An interventional cardiologist performs right-heart catheterization to measure pressures and, when obtained, oxygen saturation and cardiac output, while imaging the native coronary arteries and bypass grafts. A typical use is a diagnostic cath-lab evaluation of a patient with prior CABG when both right-sided hemodynamics and coronary or graft anatomy are needed, such as assessing ischemia alongside heart-failure or pulmonary-pressure findings. The code includes imaging supervision and interpretation for the angiographic work.
Choose 93457 when the documented session includes right-heart catheterization, coronary angiography, and bypass-graft angiography; coronary angiography without graft imaging is a different level, and left-heart catheterization changes code selection. The report should identify the catheterization measurements and the native-vessel and graft images interpreted. A 0-day global period includes same-day preoperative and postoperative care. Bill the global service without a component modifier, or use modifier 26 for interpretation or TC for equipment and staff. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 is inappropriate for this anatomy. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

93457 billing questions
Can I report 93457 when bypass grafts are not imaged?
No. The service includes right-heart catheterization with coronary and bypass-graft angiography; 93456 is the related level for right-heart catheterization with coronary angiography without graft imaging.
How does 93457 differ from 93459?
93457 includes right-heart catheterization, while 93459 includes left-heart catheterization with coronary and bypass-graft angiography. Select based on the catheterization actually performed.
When should I use modifiers 26 or TC?
Use modifier 26 for the professional interpretation or TC for the technical equipment and staff portion. Reporting the code without either modifier represents the global service.
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 other procedures are paid at 50%.
Is modifier 50 appropriate for 93457?
No. The anatomy and service represented by this code make modifier 50 inappropriate.
What should the procedure report document?
Document the right-heart catheterization measurements and the angiographic work on both the native coronary arteries and bypass grafts, including the images interpreted.
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.
