What 93456 covers
A cardiologist typically performs this diagnostic study in a cardiac catheterization laboratory. Catheters are used to measure pressures and hemodynamics in the right heart and pulmonary circulation, while contrast imaging evaluates the coronary arteries. It may be selected when the clinical evaluation needs both right-sided hemodynamic information and anatomic assessment of coronary disease. The service does not include left heart catheterization or bypass graft angiography.
Report 93456 when both the right heart catheterization and coronary angiography are performed; documentation should support the clinical need, right-sided measurements, and coronary imaging and findings. The code has a 0-day global period, so same-day preoperative and postoperative care is included. It may be billed globally or with modifier 26 for interpretation or TC for the technical portion. When other procedures subject to the standard multiple procedure reduction are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

93456 billing questions
When should 93456 be chosen over 93451?
Use 93456 when the same diagnostic session includes right heart catheterization and coronary angiography. Use 93451 when the service is right heart catheterization without the coronary imaging.
How does 93456 differ from 93454?
93456 includes right-sided hemodynamic catheterization along with coronary angiography. 93454 describes coronary angiography without the right heart catheterization.
Can right heart catheterization or coronary angiography be billed separately with 93456?
Both services are represented in 93456 when performed as part of the combined study. Do not separately report the component service for the same work.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation and modifier TC identifies the technical portion; billing without either modifier represents the global service.
Is modifier 50 appropriate, and how are other same-session procedures handled?
Modifier 50 is inappropriate for this code. When another procedure subject to the standard multiple procedure reduction is performed in the same session, the highest-valued procedure is paid in full and the others at 50%.
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.
