Clinical & Coding Specifications
Clinical Context
A 65-year-old patient with a history of chest pain and risk factors for coronary artery disease presents to the hospital outpatient department. The cardiologist suspects atherosclerotic heart disease with unstable angina. The patient undergoes coronary angiography with left heart catheterization, including intraprocedural injections for left ventriculography, to assess coronary anatomy and left ventricular function. Imaging supervision and interpretation are performed during the procedure to guide clinical decision-making.
