What 93451 covers
A cardiologist typically performs this catheter-based study in a hospital catheterization laboratory. The catheter is advanced through the venous circulation to assess right atrial, right ventricular, pulmonary artery, and wedge pressures. Oxygen saturation and cardiac output are measured when performed. A common use is evaluating suspected pulmonary hypertension; the findings can also help assess cardiac filling pressures and hemodynamics in other cardiac conditions.
Report this service when the work is limited to right heart catheterization, rather than a combined left-sided study or coronary angiography. The record should support the clinical indication, catheterization performed, pressure and other hemodynamic findings, and the interpretation. A global claim includes the professional and technical services; modifier 26 identifies interpretation, while TC identifies equipment and staff. Same-day preoperative and postoperative care is included in the 0-day global period. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others are subject to the standard reduction. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

93451 billing questions
How does 93451 differ from a left or combined heart catheterization?
Use 93451 for right-sided pressure and hemodynamic assessment alone. A left-sided study or a combined right- and left-sided study has a different code.
Can 93451 be reported with coronary angiography?
When coronary angiography is part of the service, consider the code that describes the right heart study together with coronary imaging, such as 93456, rather than reporting 93451 as though it were the complete service.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
Are pressure measurements or oxygen saturation separately reported?
These are elements of the right heart catheterization when performed. The record should show the measurements obtained and their findings; the code is not reported separately for each chamber or measurement.
How does the multiple-procedure payment rule affect 93451?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard 50% reduction.
Can an assistant or co-surgeon be billed for this procedure?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
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.
