HCPCS Section
Temporary Codes for Use with Outpatient Prospective Payment System

C7552 is a valid 2026 HCPCS code meaning Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation; with catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) including intraprocedural injection(s) for bypass graft angiography and right heart catheterization with intravascular doppler velocity and/or pressure derived coronary flow reserve measurement (coronary vessel or graft) during coronary angiography including pharmacologically induced stress, initial vessel or (R hrt art/grft ang hrt flow) for short. HCPCS C7552 has been effective since 01/01/2024 and applies to Surgery.
