CPT code 37197 covers percutaneous endovascular removal of a foreign body from a blood vessel, with included radiological supervision and interpretation to guide catheter-based retrieval. This procedure is clinically important because retained intravascular foreign bodies — such as broken catheters, wires, or embolized devices — can cause vascular injury, infection, thrombosis, and other serious complications; timely, image-guided removal reduces those risks. Nationwide, hospitals and interventional radiology services routinely use this code when documenting catheter-based retrieval procedures performed through a percutaneous access.

Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service delivery, common billing considerations, and the typical sites of service where the procedure is performed. The publication highlights national benchmarking themes and payer coverage patterns, explains where CPT code 37197 fits within interventional vascular services, and summarizes policy and reimbursement factors that affect coding and billing for percutaneous foreign body removal. Data not available in the input will be noted as such where applicable.
