What 93459 covers
A cardiologist or other qualified physician performs this invasive diagnostic study, usually in a hospital catheterization laboratory. It combines left-heart catheterization with imaging of the native coronary arteries and bypass grafts, such as saphenous vein or internal mammary artery grafts, in a patient with prior coronary artery bypass surgery. Left ventriculography may be performed as part of the study, but is not required for the code.
Select 93459 when the documented service includes left-heart catheterization, coronary angiography, and bypass-graft angiography; the record should identify the catheterization and the native-vessel and graft imaging performed. The code includes the diagnostic imaging supervision and interpretation. CMS allows global billing or separate professional interpretation (modifier 26) and technical service (modifier TC). It has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same 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.

93459 billing questions
When should 93459 be chosen over 93458?
Use 93459 when the left-heart catheterization and coronary angiography include bypass-graft angiography. Use 93458 when graft angiography is not part of the study.
Is left ventriculography required?
No. Left ventriculography may be performed during the study, but it is not required for 93459.
Can coronary or graft angiography be billed separately?
The coronary and bypass-graft imaging and its supervision and interpretation are included in 93459 for the same study. Do not separately report 93455 for that same imaging.
How are the professional and technical services reported?
Report modifier 26 for the professional interpretation or modifier TC for the technical service. Reporting without either modifier represents the global service.
How does the multiple-procedure rule affect payment?
For multiple procedures in the same session, CMS pays the highest-valued procedure in full and pays other procedures at 50%.
What documentation is needed for an assistant at surgery?
Document the medical necessity for the assistant. CMS pays an assistant at surgery for this code only when that necessity is documented.
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.
