Summary & Overview
CPT 36557: Pediatric Central Venous Catheter Placement
CPT code 36557 captures placement of a tunneled or nontunneled central venous catheter without a subcutaneous port or pump in a major vein or directly into the right atrium for patients under five years old. This pediatric-specific procedural code matters nationally because it is used to bill for critical vascular access when long-term or reliable intravenous therapy is needed in very young children, influencing hospital resource use, perioperative planning, and pediatric specialty reimbursement patterns.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical and billing context for CPT code 36557, including typical sites of service and the service type. The publication outlines common payer considerations, benchmarking information where available, and relevant policy or coverage themes affecting pediatric central venous access. Clinical context includes indications for central venous infusion in young children and operational implications for settings such as operating rooms and interventional radiology suites.
The report provides actionable reference material for coding, billing, and administrative teams: definitions and scope of CPT code 36557, payer coverage landscape, and areas where policy updates or clarifications are commonly sought. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 36557 describes placement of a central venous catheter without a subcutaneous port or pump in a major vein that carries blood to the heart or directly into the right atrium for the purpose of administering medication, nutrients, or fluids. The code applies when the service is performed in an individual younger than five years of age.

Service type: Invasive vascular access procedure for central venous infusion
-
Typical site of service: Hospital operating room, interventional radiology suite, or inpatient/ambulatory surgical setting where pediatric central venous access is performed
Clinical & Coding Specifications
Clinical Context
A typical patient is a child younger than five years old who requires long-term intravenous access for administration of medications, parenteral nutrition, or frequent blood sampling. Common scenarios include an infant with congenital heart disease needing prolonged IV inotropic support, a toddler with oncologic chemotherapy needs, or a young child with short gut syndrome requiring total parenteral nutrition. The clinical workflow begins with pediatric evaluation and consent, review of indications and coagulation status, selection of an appropriate central venous site (internal jugular, subclavian, or femoral vein), ultrasound-guided venous access, placement of a tunneled or non-tunneled central venous catheter with confirmation of catheter tip position by fluoroscopy or chest radiograph, securement and dressing application, and post-procedure monitoring for complications (pneumothorax, bleeding, infection). Documentation includes indication, consent, site, anesthesia or sedation used, catheter type, number of lumens, length and tip position, imaging confirmation, and any complications or additional procedures.
