CPT® Code 75756

Internal mammary angiography is a specialized vascular procedure that focuses on assessing the blood flow through the internal mammary artery, which is also known as the internal thoracic artery. This artery originates from the subclavian artery and plays a significant role in cardiovascular procedures, particularly as a potential graft during coronary artery bypass surgery. The primary purpose of this angiography is to visualize the internal mammary artery's structure and function, allowing healthcare professionals to identify any abnormalities such as narrowing (stenosis) or blockages (embolism) that could impede blood flow. The procedure involves the use of imaging technology to guide the placement of a catheter into the artery, enabling the injection of contrast dye. This dye enhances the visibility of the blood vessels on imaging studies, allowing for real-time observation of blood flow. Additionally, the findings from the angiography can be documented and analyzed further, providing critical information for the diagnosis and management of cardiovascular conditions. The CPT® Code 75756 specifically denotes the radiological supervision and interpretation of this angiographic procedure, which includes the radiologist's oversight, the analysis of the imaging results, the generation of a written report, and any necessary consultations with referring physicians regarding the implications of the findings and potential next steps in patient care.
