Nationally, this code is relevant for documenting complex intraoperative support when CPB is required to manage hemodynamics or procedural complications during TAVI/TAVR. Accurate use of the code affects procedural reporting and the clinical record for high-acuity structural heart interventions.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for CPB use in transcatheter valve procedures, typical sites of service, and the coding scope for percutaneous peripheral cannulation.
