Cardiac Catheterization and Coronary Angiography - Medicare Advantage

Covers diagnostic cardiac catheterization and coronary angiography (including left/right heart catheterization, coronary angiography, associated intravascular imaging/measurements such as IVUS/OCT, and related procedural components such as left ventriculography and PCI where addressed by the LCDs). Intended for patients with suspected or known ischemic heart disease (new or chronic chest pain, abnormal stress test), dyspnea of cardiac origin, valvular or congenital heart disease, heart failure/cardiomyopathy and other structural/hemodynamic assessments; coverage is governed by CMS Local Coverage Determinations L33959/L33557 and the excerpt contains no explicit exclusions, frequency limits or prior‑authorization language—many code descriptors apply only to the initial vessel or to components “when performed,” so review the full LCDs for specific limitations and billing requirements.
