Summary & Overview
CPT 93568: Pulmonary Artery Angiography During Cardiac Catheterization
CPT code 93568 represents pulmonary artery angiography performed during cardiac catheterization, in which a catheter is placed into the pulmonary artery and contrast is injected to visualize pulmonary arterial anatomy and assess blood flow. This diagnostic imaging service is integral to evaluating pulmonary vascular pathology and guiding interventional decision-making during invasive cardiology procedures. Nationally, the code matters because it captures a discrete imaging and interpretive service within catheterization procedures that affects hospital and physician billing, quality reporting, and utilization measurement.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and expected service composition. The publication also presents benchmark metrics where available, notes relevant policy or coverage considerations at a national level, and explains coding and documentation elements that determine correct reporting of the service.
The content is intended to help billing managers, clinical coders, and policy analysts understand the clinical intent of CPT code 93568, where it fits within catheterization procedures, and what areas to consider for documentation and payer engagement. Data not available in the input is acknowledged where applicable.
Billing Code Overview
CPT code 93568 describes pulmonary artery angiography performed during cardiac catheterization. During the procedure, a catheter is advanced into the pulmonary artery and contrast dye is injected to visualize the pulmonary arterial anatomy and assess blood flow. The provider supervises image acquisition, interprets the angiographic images, and documents findings in a formal report.
-
Service type: Diagnostic vascular imaging performed as part of a cardiac catheterization procedure
-
Typical site of service: Inpatient or outpatient cardiac catheterization laboratory (catheterization lab) or interventional cardiology suite
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with progressive exertional dyspnea, hypoxemia, and a history of systemic sclerosis is referred for invasive hemodynamic assessment to evaluate suspected pulmonary hypertension. The patient is admitted to the cardiac catheterization laboratory where the interventional cardiology team performs right heart catheterization. During the procedure, a catheter is advanced from a central venous access site into the pulmonary artery; contrast is injected to visualize the pulmonary arterial tree and assess flow dynamics and possible vascular obstruction. The supervising physician interprets angiographic images in real time, documents measurements of pulmonary artery pressures and cardiac output, reviews the contrast injection series for perfusion defects or thromboembolic disease, and issues a formal procedure report. Typical workflow steps include pre-procedure consent and review, vascular access (usually femoral or internal jugular), right-sided catheter navigation, selective pulmonary angiography with dye injection, interpretation and hemodynamic measurements, removal of catheters, hemostasis, and post-procedure monitoring in recovery or an observation unit.
