Clinical Context
A 7-year-old child with progressive cardiopulmonary insufficiency secondary to congenital heart disease is scheduled for percutaneous peripheral cannula placement to establish extracorporeal circulation. The child presents with worsening hypoxemia, signs of low cardiac output, and the clinical team determines temporary extracorporeal support is required for stabilization prior to definitive surgical repair. The procedure is performed in a cardiac catheterization laboratory or hybrid operating room under general anesthesia. Vascular access is obtained via a small percutaneous incision and a peripheral cannula is advanced under fluoroscopic guidance into the appropriate central or peripheral vessel to allow initiation of extracorporeal circulation. The multidisciplinary workflow includes pre-procedure imaging review, anesthesia induction with pediatric monitoring, sterile vascular access by the interventional cardiologist or cardiothoracic surgeon, fluoroscopic confirmation of cannula position, hemodynamic monitoring while initiating extracorporeal flow, and post-procedure transfer to the pediatric intensive care unit for ongoing support and monitoring. Documentation elements include indication, informed consent, cannula size and site, fluoroscopy time, any complications, concurrent procedures, and disposition.

53 | Discontinued procedure (safety) | When procedure is started but halted due to an adverse event or safety concern prior to completion
59 | Distinct procedural service | When a separate and distinct procedure is performed at a different anatomic site on the same day
62 | Two surgeons | When two surgeons work together as primary surgeons performing portions of the procedure
63 | Procedure performed on infants less than 4 kg | Not typically applicable for age ≥ six years; included for completeness if patient weight criteria change
78 | Unplanned return to the OR by the same physician following initial procedure for a related procedure during the postoperative period | When an immediate reoperation is required for a complication related to 33952
79 | Unrelated procedure or service by same physician during postoperative period | When an unrelated procedure is performed during the global period
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | When an assistant at surgery from listed midlevel providers participates per payer rules
ET | Eligible to be paid under multiple procedure payment reduction (MPPR) guidelines | Use per payer MPPR policies when applicable
