Percutaneous Left Atrial Appendage Closure (LAAC)
Patients with atrial fibrillation (AF), an irregular heartbeat, are at an increased risk of stroke. The left atrial appendage (LAA) is a tubular structure that opens into the left atrium and has been shown to be one potential source for blood clots that can cause strokes. While thinning the blood with anticoagulant medications has been proven to prevent strokes, percutaneous LAAC has been studied as a non-pharmacologic alternative for patients with non-valvular AF who are at high risk for stroke.
CMS issued a Medicare National Coverage Determination (NCD) on February 8, 2016 which allows for coverage of LAAC under Coverage with Evidence Development (CED) with certain conditions. The complete determination is available on our website.
