Summary & Overview
CPT 75741: Pulmonary Artery Catheter Angiography, Supervision & Interpretation
CPT code 75741 covers the radiological supervision and interpretation for angiographic imaging associated with the unilateral placement of a catheter in the pulmonary artery. This service supports clinicians by providing real‑time imaging interpretation during invasive catheter placement and post‑procedure review, which can be critical for diagnosing pulmonary vascular disease, thromboembolism, and for guiding interventional therapies. Nationally, accurate coding for 75741 matters for clinical documentation, quality reporting, and consistent reimbursement across facilities.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical service settings, common billing modifiers and considerations (listed separately in the publication), and which payers are included in benchmarking. The publication also outlines where 75741 fits within radiology service lines and how it relates to angiographic workflows.
This summary equips billing managers, radiology administrators, and policy analysts with a clear description of the service represented by 75741, the typical sites of service, and what to expect in payer coverage discussions. Data not available in the input is noted where appropriate in other sections of the publication.
Billing Code Overview
CPT code 75741 describes the radiological supervision and interpretation of angiographic imaging performed for the unilateral placement of a catheter in the pulmonary artery. Angiography uses a radiopaque contrast agent to visualize blood vessels under X‑ray and assist in diagnosis and treatment planning.
Service Type: Diagnostic radiology — vascular angiography and interpretation
Typical Site of Service: Hospital radiology department, interventional radiology suite, or outpatient imaging center
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents with unexplained hypoxemia and suspected pulmonary embolism after clinical evaluation and D-dimer testing. The interventional radiology team schedules a diagnostic pulmonary angiography to visualize the pulmonary arterial tree. Under conscious sedation in the angiography suite (typical site of service: hospital outpatient or inpatient radiology/angiography suite), a right femoral or jugular venous access is obtained and a catheter is advanced into a unilateral pulmonary artery branch. A radiopaque contrast agent is injected while fluoroscopic imaging is performed. The interpreting radiologist provides real-time radiological supervision and interpretation of catheter placement and angiographic images, documents findings such as vessel occlusion or thrombus, and communicates results to the ordering physician for management decisions (thrombolysis, embolectomy, anticoagulation). Typical workflow elements: pre-procedure consent and coagulation review, vascular access and catheter manipulation, contrast injection with digital subtraction angiography, radiologist interpretation and procedural documentation, post-procedure monitoring in recovery.
