Summary & Overview
CPT 36597: Reposition Central Venous Catheter, Fluoroscopic Guidance
CPT code 36597 covers fluoroscopically guided repositioning of a previously placed central venous catheter that has become dislodged or infected. Nationally, this code captures a common interventional radiology and vascular access service used to restore central line function and address potential device-related infection without full catheter removal. Use of 36597 affects facility and professional billing workflows and influences utilization reporting for vascular access management.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, typical sites of service (hospital interventional radiology or hospital procedure rooms using fluoroscopy), and what to expect in terms of code application. The publication outlines benchmarking considerations, common modifier practice, and relevant policy or coverage themes that influence claim adjudication for device repositioning under imaging guidance.
This summary presents national-level context for providers, coders, and payers who manage central venous access services, helping stakeholders understand where the code fits in clinical workflows and billing processes.

Billing Code Overview
CPT code 36597 describes the repositioning of a previously placed central venous catheter that has become dislodged or infected, performed under fluoroscopic guidance. This procedure typically involves manipulation or exchange of the catheter to restore proper placement or address device-related infection while using real-time imaging to confirm position and patency.
-
Service type: Image-guided vascular device repositioning
-
Typical site of service: Hospital interventional radiology suite or hospital-based procedure room with fluoroscopy

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a previously placed tunneled central venous catheter (e.g., Hickman, port-a-cath external catheter) that has become partially dislodged, malpositioned, or associated with a localized catheter-related infection requiring repositioning rather than full removal. The patient presents to an interventional radiology or vascular access suite, often from an oncology clinic, dialysis center, or inpatient unit, with symptoms such as difficulty flushing the catheter, poor blood return, pain at the catheter site, or erythema suggesting localized infection. Fluoroscopic guidance is used to visualize catheter tip position and vascular anatomy. Under sterile conditions, conscious sedation or monitored anesthesia care is provided as needed. The provider advances, retracts, or manipulates the catheter over a wire or via catheter exchange techniques to restore appropriate tip location (typically at the cavoatrial junction). Post-repositioning contrast injection and fluoroscopic images confirm correct placement and patency. Documentation includes indication, informed consent, sedation level, fluoroscopy time, devices used, and immediate postprocedure assessment. Typical site of service is an interventional radiology suite or ambulatory surgical center, with possible inpatient performance when clinically indicated.
