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.

The transcatheter intracoronary infusion of supersaturated oxygen (CPT® Code 0659T) is indicated for the following conditions:
The procedure for transcatheter intracoronary infusion of supersaturated oxygen involves several critical steps to ensure effective delivery of the therapy:
Following the transcatheter intracoronary infusion of supersaturated oxygen, patients are typically monitored for any immediate complications related to the procedure. Continuous assessment of cardiac function and vital signs is essential to ensure that the infusion has effectively restored blood flow and that there are no adverse reactions. The expected recovery period may vary based on individual patient factors and the extent of the myocardial infarction. Additional follow-up care may include cardiac rehabilitation and ongoing monitoring of heart health to prevent future cardiac events.

| 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
