Dilate R Pulm Art w Expndbl Int Dev, Perc, New Tech 11

This code describes a minimally invasive procedure to widen a narrowed right pulmonary artery. A balloon-expandable stent or similar device is inserted through a catheter, typically from a peripheral vessel, to improve blood flow to the right lung. This intervention aims to alleviate symptoms and improve cardiac function in patients with pulmonary artery stenosis.

Use this code when a patient undergoes percutaneous dilation of the right pulmonary artery using an intraluminal device, such as a stent, to treat stenosis. This procedure is often performed in cases of congenital heart disease or acquired pulmonary hypertension where the right pulmonary artery is significantly obstructed. It is applicable for the initial placement of such a device in this specific location.

• Ensure documentation clearly specifies the right pulmonary artery as the treated vessel.
• Verify that an expandable intraluminal device (e.g., stent) was used, not just balloon angioplasty without a device.
• Confirm the approach was percutaneous; open or endoscopic approaches would map to different codes.
