Question: My cardiologist stated that he performed limited coronary angiography and an intravascular ultrasound (IVUS). How should I bill this? North Carolina Subscriber Answer: Most likely, the cardiologist meant that he or she performed angiography on only one coronary artery. In this case, you should report 93508 (Catheter placement in coronary artery[s], arterial coronary conduit[s], and/or venous coronary bypass graft[s] for coronary angiography without concomitant left heart catheterization) appended with modifier -26 (Professional component) if the procedure was performed in a facility other than the physician's office. Finally, you should report the IVUS using +92978-26 (Intravascular ultrasound [coronary vessel or graft] during diagnostic evaluation and/or therapeutic intervention including imaging supervision, interpretation and report; initial vessel [list separately in addition to code for primary procedure]). Note: Codes 93545 and 93556 are paid if only one coronary artery is injected and imaged or all are injected and imaged.
You should also bill 93545 (Injection procedure during cardiac catheterization; for selective coronary angiography [injection of radiopaque material may be by hand]) and 93556 (Imaging supervision, interpretation and report for injection procedure[s] during cardiac catheterization; pulmonary angiography, aortography, and/or selective coronary angiography including venous bypass grafts and arterial conduits [whether native or used in bypass]). You should append 93556 with modifier -26 as well.
