Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting with symptoms suggestive of right-sided heart failure, such as shortness of breath, peripheral edema, or evidence of pulmonary heart disease. The patient is referred to the cardiac catheterization laboratory for evaluation. The interventional cardiologist performs catheter placement in the coronary arteries for coronary angiography, including intraprocedural injections and imaging supervision. Additionally, a right heart catheterization is performed to assess hemodynamics and guide further management. This workflow is common in facility settings such as hospital outpatient departments.
