Summary & Overview
CPT 33974: Removal of Intra–Aortic Balloon with Ascending Aortic Repair
CPT code 33974 denotes surgical removal of a previously placed intra–aortic balloon from the ascending aorta with concurrent repair of the ascending aorta, which may involve graft use. This procedure is generally performed after patient stabilization following initial hemodynamic support and is distinct from the balloon placement procedure. Nationally, this code is relevant for acute cardiovascular surgical care, perioperative resource planning, and coding clarity for hospitals and cardiac surgery programs.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for use of the code, typical sites of service, and payer coverage considerations. The publication outlines where this service fits into surgical workflows, coding boundaries (placement versus removal/repair), and common clinical scenarios that prompt use of the code.
The report summarizes benchmarking and reimbursement context where available, highlights policy or coverage considerations affecting hospitals and surgical teams, and clarifies reporting practices tied to intra–aortic balloon management. Data not available in the input is noted as such where relevant.
Billing Code Overview
CPT code 33974 describes the removal of a previously inserted intra–aortic balloon from the ascending aorta with repair of the ascending aorta, which may include use of a graft. The procedure is performed once the patient stabilizes after initial intervention. Placement of the intra–aortic balloon catheter is a separately reportable procedure.
-
Service type: Surgical removal of intra–aortic balloon with ascending aortic repair
-
Typical site of service: Hospital inpatient or operating room during cardiovascular surgery or postoperative reintervention
Clinical & Coding Specifications
Clinical Context
A typical patient is a hemodynamically unstable adult admitted to the cardiothoracic surgery service after acute myocardial infarction complicated by cardiogenic shock or severe left ventricular dysfunction. An intra-aortic balloon pump (IABP) was previously inserted percutaneously or via surgical cutdown into the ascending aorta to provide temporary mechanical circulatory support. Once the patient stabilizes hemodynamically, the cardiothoracic surgeon returns to the operating room or performs the removal at the bedside in a procedure area to explant the IABP, inspect and repair the ascending aorta at the insertion site, and, if required, perform patch repair or interposition grafting to restore vascular integrity. The workflow includes pre-procedure hemodynamic assessment, sedation or general anesthesia as indicated, sterile exposure of the aortic entry site, removal of the catheter, direct visualization of the aortic wall, repair or graft placement, hemostasis verification, and postoperative monitoring in the intensive care unit.
