What 93455 covers

This service evaluates the native coronary arteries and surgically created bypass grafts using catheter-based contrast injections and imaging. It is commonly performed by a cardiologist in a cardiac catheterization laboratory when a patient with prior coronary artery bypass surgery needs diagnostic assessment of coronary blood flow or graft patency. Aortography may be included when performed as part of the graft assessment.

Report 93455 when the documented study includes coronary angiography and bypass graft angiography, without adding a left-heart catheterization service. The procedure report should identify the vessels and grafts studied, the imaging performed, and the interpreting physician’s findings. Medicare recognizes professional interpretation and technical services separately with modifiers 26 and TC; billing without either modifier represents the global service. The code has a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

93455 billing questions

When should 93455 be chosen over 93454?

Use 93455 when the diagnostic study includes bypass graft angiography along with coronary angiography. Use 93454 when coronary angiography is performed without graft imaging.

Does 93455 include left-heart catheterization?

No. If left-heart catheterization is also performed with coronary and bypass graft angiography, compare the documentation with 93459.

Can the professional and technical services be billed separately?

Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.

How does Medicare handle multiple procedures in the same session?

The highest-valued procedure is paid in full, and other procedures subject to the multiple-procedure rule are paid at 50%.

What documentation supports reporting 93455?

The procedure report should show coronary imaging and bypass graft imaging, identify the vessels or grafts evaluated, and include the interpreting physician’s findings.

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.
