Interventional Cardiology in the ASC and Outpatient Setting

Interventional cardiology covers catheter-based diagnosis and treatment of coronary and structural heart disease, including diagnostic angiography, angioplasty, and stenting through small vascular access points.

These services sit in the cardiac CPT range 92920 to 93799. For example, 93458 reports a left heart catheterization with coronary and left ventricular angiography, and 92928 reports placement of an intracoronary stent in a single vessel. Some codes are ASC-eligible and can be performed in a certified ambulatory surgery center, while others are typically done in a hospital outpatient department or office instead. DataLily AI's procedure library tracks CPT-specific prior authorization and documentation requirements so these checks happen up front rather than after a denial.

Interventional Cardiology codes(50)

Are interventional cardiology procedures done in an ASC?

Some are, but much catheter-based cardiac work is performed in an office-based lab or hospital outpatient setting, which is why many claims use place-of-service 11. Whether a specific code suits the ASC setting depends on its ASC-eligibility status, worth confirming before scheduling. Some codes are ASC-eligible and can be performed in a certified ambulatory surgery center, while others are typically done in a hospital outpatient department or office instead. Always confirm the ASC-eligibility status and payer policy for the exact CPT code before scheduling.

What CPT codes does interventional cardiology use?

Interventional cardiology codes fall in the cardiac range 92920 to 93799. This includes diagnostic procedures such as left heart catheterization with coronary and ventricular angiography (93458), therapeutic interventions such as single-vessel coronary stenting (92928) and single-artery coronary angioplasty (92920), and physiologic measurements such as intravascular Doppler velocity and pressure assessment (93571). Our dataset maps 50 ASC-relevant CPT codes to this specialty.

What is the difference between a diagnostic and an interventional cardiac code?

Diagnostic codes describe imaging and measurement used to assess the heart and coronary arteries, such as a left heart catheterization with angiography (93458) or intravascular Doppler and pressure readings (93571). Interventional codes describe treatment delivered through the catheter, such as balloon angioplasty (92920) or stent placement (92928). The distinction matters for documentation and for confirming coverage and prior authorization, since requirements can differ between a diagnostic study and a therapeutic intervention.
