The Centers for Medicare & Medicaid Services (CMS) is mulling over whether a national coverage determination is warranted for computed tomographic angiography (CTA) to diagnose coronary artery disease. The agency also said that it will evaluate the need for coverage with evidence development.

Some pushing for more usage of cardiac CTA believe it will lead to a reduction in cardiac catheterization. However, CMS is fretting over its concern that the procedure is being rapidly adopted despite the lack of evidence that it is effective at improving clinical outcomes.
CMS is currently accepting public input regarding its national coverage analysis.
