Summary & Overview
CPT 36582: Complete Replacement of Tunneled Central Venous Catheter
CPT code 36582 denotes the complete replacement of a tunneled central venous access catheter when the device is blocked, damaged, or malfunctioning. This code is clinically significant because tunneled catheters are critical for long-term vascular access in patients requiring infusion therapy, dialysis adjuncts, or long-term venous access. Timely replacement impacts infection risk, continuity of therapy, and facility resource use across inpatient and outpatient procedural settings.
Key payers in this national overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes coverage patterns and operational benchmarks where available, highlights the clinical context for use of the code, and outlines coding considerations relevant to billing and claims adjudication.
Readers will learn the clinical definition and typical settings for CPT code 36582, expected site-of-service considerations, and what inputs are available versus missing for a full payer-level benchmarking analysis. The piece also identifies where additional documentation or coding detail is commonly required for claims processing. Data not available in the input is clearly noted so stakeholders understand the limits of the current summary.
Billing Code Overview
CPT code 36582 describes a complete replacement of a tunneled central venous access (CVA) catheter performed when the existing catheter is blocked, damaged, or malfunctioning. This procedure involves removing the nonfunctional tunneled catheter and placing a new tunneled central venous catheter during the same operative episode.
-
Service type: Surgical catheter replacement / vascular access procedure
-
Typical site of service: Hospital operating room, ambulatory surgical center, or other procedural setting where tunneled central venous catheters are placed and managed

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult receiving long-term tunneled central venous access for hemodialysis, chemotherapy, parenteral nutrition, or long-term antibiotics who presents with catheter malfunction such as persistent occlusion, extraluminal damage, or confirmed catheter fracture. The patient often reports inability to aspirate blood, recurrent alarms on dialysis machines, swelling at the exit site, or signs of infection. Initial evaluation includes physical exam, assessment of catheter function, chest radiograph to confirm catheter tip position and integrity, and attempts at non-surgical salvage (thrombolytic instillation, guidewire exchange) when clinically appropriate. When the catheter is irreversibly blocked, damaged, or malfunctioning and cannot be salvaged by over-the-wire exchange or thrombolysis, the treatment plan proceeds to a complete tunneled central venous access catheter replacement under sterile conditions.
The procedure is typically performed in an interventional radiology suite, operating room, or specialized procedure room. The workflow includes informed consent, appropriate pre-procedure labs (coagulation profile), ultrasound and fluoroscopic guidance for venous access and catheter placement, removal of the malfunctioning tunneled catheter, placement of a new tunneled catheter tunneled subcutaneously to a new or existing exit site, and confirmation of catheter tip position by fluoroscopy or radiograph. Post-procedure monitoring includes assessment for bleeding, pneumothorax, catheter function testing (aspiration and flush), and documentation of device serial/lot information for billing and inventory. Documentation should capture reason for replacement (blockage, damage, malfunction), prior attempts at salvage, laterality, approach, and any complications.
