Modifiers may be applicable.Refer to current CPT guidelines for specific modifier usage.
Medical necessity for this procedure must be established.This typically involves demonstrating significant left ventricular outflow tract obstruction causing symptoms or impacting cardiac function, and that surgical intervention is the appropriate treatment.
The surgeon is responsible for performing the procedure, including opening the chest, removing obstructive tissue, enlarging the left ventricular outflow tract with a patch, and closing the incision. Anesthesia and post-operative care are typically handled by other specialists.
In simple words: This procedure widens a narrowed section in the heart that carries blood from the heart's main pumping chamber to the body.The surgeon uses a patch to create more space in this area, improving blood flow.
This code describes a surgical procedure to repair an obstruction in the left ventricular outflow tract by enlarging the outflow tract with a patch.The procedure involves opening the chest, usually via sternotomy, opening the pericardium, and using a portion of the pericardium or other suitable material as a patch. The surgeon opens the ascending aorta above the aortic valve, removes obstructive tissue, and enlarges the left ventricular outflow tract using the patch.
Example 1: A pediatric patient with congenital heart disease causing left ventricular outflow tract obstruction., An adult patient with acquired left ventricular outflow tract obstruction due to prior surgery or other cardiac conditions., A patient with left ventricular outflow tract obstruction requiring surgical intervention due to severe symptoms.
Documentation should include the diagnosis necessitating the procedure, operative details such as the size and type of patch used, any intraoperative complications, and post-operative status. Pre-operative imaging studies and other diagnostic tests should also be documented.
