CPT code 93454: Coronary angiography, without graft or left-heart catheterization2026 Medicare rate & RVUs

Medicare pays $877.78 for 93454 nationally in the office. Local office rates run $764.30–$1,188.79.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 93454 covers

This service uses catheter-based contrast injections and imaging to assess the native coronary arteries. A cardiologist, commonly one performing diagnostic or interventional cardiac procedures, typically performs it in a cardiac catheterization laboratory. The study supports evaluation of suspected or known coronary artery disease, such as in a patient with symptoms or other findings that warrant anatomic assessment. It includes the imaging supervision and interpretation for the coronary study.

Select 93454 when the documented service is coronary angiography without bypass-graft imaging or left-heart catheterization; use a different code when those additional services are performed. The report should support the catheter and injection work, the coronary images obtained, and the physician’s interpretation. The 0-day global period includes same-day preoperative and postoperative care. Modifier 26 identifies the professional interpretation, modifier TC the technical service, and no modifier the global service. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
