In simple words: This code covers the doctor's work in looking at and interpreting X-ray images of the blood vessels in one lung. A special dye is used to make the blood vessels show up clearly on the X-ray. The doctor watches the procedure and makes sure the images are taken correctly. They then study the images to check for any problems.

This CPT code, 75741, encompasses the radiological supervision and interpretation of a unilateral, selective pulmonary angiogram.The procedure involves the catheterization of one pulmonary artery, requiring the insertion of a catheter, typically via femoral artery access, advanced under fluoroscopic guidance to the desired pulmonary artery branch. Contrast material is injected, and images are acquired and interpreted by the radiologist to assess the pulmonary vasculature for pathologies such as pulmonary embolism or other vascular anomalies.This code only represents the radiologist's services in the supervision and interpretation of the imaging; it does not include the procedural aspects of catheter placement and contrast injection.

Example 1: A patient presents with suspected pulmonary embolism.A selective pulmonary angiogram is performed to confirm the diagnosis. The radiologist, using code 75741, supervises the procedure and interprets the resulting images to identify any pulmonary emboli., A patient undergoes a lung transplant evaluation.A selective pulmonary angiogram is performed to assess the pulmonary vascular anatomy and rule out any vascular abnormalities.The radiologist uses code 75741 for the supervision and interpretation of this unilateral study., A patient with known pulmonary hypertension requires monitoring of their pulmonary vascular resistance.A serial selective pulmonary angiogram is done.The radiologist reports 75741 for each separate session's radiological supervision and interpretation.

*Physician's order specifying the need for a selective pulmonary angiogram.*Detailed procedural report documenting catheter placement, contrast injection technique, image acquisition parameters, and findings.*Radiologist's interpretation report describing the findings and their clinical significance, including image quality assessment.*Relevant patient history and physical examination notes supporting the medical necessity of the procedure.

** This code is specifically for unilateral procedures.If a bilateral procedure is performed, code 75743 should be used.The use of this code requires careful consideration of the CPT guidelines to avoid improper billing practices. Always cross-reference with the most current CPT guidelines.
