Cardiac catheterization
About 93451: Right heart catheterization with hemodynamic assessment
Reports catheter-based assessment of right-sided cardiac and pulmonary pressures, oxygen saturation, and cardiac output, commonly during evaluation of pulmonary hypertension.
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.
CMS billing rules for 93451
- Global period
- Minor procedure with a 0-day global period: same-day preoperative and postoperative care is included.
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.
- Multiple procedures
- Standard multiple procedure reduction: the highest-valued procedure is paid in full and others at 50% when performed in the same session.
- Bilateral procedures
- Bilateral adjustment does not apply; the descriptor or anatomy makes modifier 50 inappropriate.
- Assistant at surgery
- Assistant at surgery is paid only with documentation of medical necessity.
- Co-surgeons
- Co-surgeons not permitted.
- Team surgery
- Team surgery 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
