Extensive Maze Surgery With Bypass

Maryland rates for HCPCS 33256

Open-heart surgery to stop atrial fibrillation, an irregular rhythm that starts in the upper chambers of the heart. The surgeon creates a pattern of controlled scar lines in the walls of those chambers so the disordered electrical signals can no longer travel, and rebuilds the chamber walls afterwards. This is the extensive version, done with a heart-lung machine taking over circulation while the heart is stopped.
