2025 CPT code 33970

Insertion of intra-aortic balloon assist device through the femoral artery, open approach.

Follow CPT coding guidelines and payer-specific rules for appropriate coding and billing.

Modifiers may apply depending on the circumstances of the procedure. Refer to current CPT guidelines for modifier usage.

Medical necessity must be supported by documentation showing that the patient's condition requires circulatory support with an IABP, and the open femoral approach is necessary due to specific circumstances.

The surgeon is responsible for the entire procedure including incision, insertion of the IABP, connecting to the console, initiating counterpulsation, and monitoring for proper function. The surgeon also manages post-operative care and weaning from the device.

IMPORTANT For percutaneous insertion, see 33967.For percutaneous removal, see 33968.For removal with femoral artery repair, see 33971.For insertion through the ascending aorta, see 33973.For removal from the ascending aorta, see 33974.

In simple words: The surgeon makes an incision in the groin to access the femoral artery and inserts a balloon pump into the aorta, the main artery from the heart. This balloon inflates and deflates to help the heart pump blood more efficiently.

This code describes an open surgical procedure where an intra-aortic balloon pump (IABP) is inserted through an incision in the femoral artery.The IABP assists the heart by increasing blood flow and reducing the heart's workload. This approach contrasts with percutaneous insertion.

Example 1: A patient presents with cardiogenic shock following a myocardial infarction. An open IABP insertion is performed via the femoral artery to stabilize the patient's hemodynamics., A patient with severe aortic stenosis requires an emergency IABP for circulatory support before undergoing valve replacement surgery. Due to unsuitable anatomy for percutaneous approach, an open insertion via the femoral artery is chosen., A patient experiencing unstable angina and refractory to medical management needs IABP support.An open femoral artery approach is used for IABP insertion to stabilize the patient before further intervention.

Documentation should include the reason for IABP insertion (e.g., cardiogenic shock, unstable angina), the surgical approach (open femoral artery), the type and size of the IABP used, intraoperative details, post-operative monitoring data, and any complications. Preoperative imaging and laboratory results relevant to the decision-making process should also be documented.
