CPT® Code 0659T

Transcatheter intracoronary infusion of supersaturated oxygen in conjunction with percutaneous coronary revascularization during acute myocardial infarction, including catheter placement, imaging guidance (eg, fluoroscopy), angiography, and radiologic supervision and interpretation

The CPT® Code 0659T refers to a specialized medical procedure known as transcatheter intracoronary infusion of supersaturated oxygen (SSO2) in conjunction with percutaneous coronary revascularization during an acute myocardial infarction (AMI). This procedure is designed to deliver hyperbaric levels of oxygen directly to damaged heart tissue, specifically targeting the ischemic areas of the heart that are affected during a heart attack. The infusion of SSO2 is particularly indicated for patients experiencing a left anterior descending ST-elevation myocardial infarction (LAD STEMI), which is recognized as one of the most critical types of heart attacks due to its potential to cause significant damage to the heart muscle. The SSO2 therapy is administered through a catheter-based approach, allowing for a direct infusion of oxygenated saline solution mixed with the patient’s own blood into the coronary arteries. This method aims to reduce the size of the infarct by restoring capillary blood flow and preventing further tissue necrosis. The procedure is typically performed in a catheterization laboratory (cath lab) shortly after the successful revascularization of the LAD artery, which is achieved through angioplasty and stenting. The SSO2 system comprises a mobile console and a disposable cartridge that generates the superoxygenated solution, ensuring that the delivery is both efficient and effective during the critical window following an acute myocardial infarction.
