Summary & Overview
CPT 36810: External Scribner-Type Cannulation for Hemodialysis
CPT code 36810 denotes an external Scribner–type cannulation procedure to establish temporary arteriovenous access for hemodialysis. This vascular access technique remains a key procedural option for patients needing immediate dialysis support and is relevant across hospitals, ambulatory surgical centers, and dialysis facilities. Nationally, accurate coding of this procedure supports appropriate tracking of dialysis care delivery, resource use, and quality measurement.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for CPT code 36810, standard sites of service, and common billing considerations. The publication summarizes national benchmarks where available, highlights notable policy and coverage updates that affect reimbursement and prior authorization, and places the procedure in clinical workflow for teams managing acute and chronic renal failure care.
This overview is intended for clinicians, billing professionals, and policy analysts seeking a clear, actionable summary of what CPT code 36810 represents, why it matters for dialysis access management, and which payers commonly cover the service. Data not available in the input is noted as such in relevant sections.
Billing Code Overview
CPT code 36810 describes an external Scribner–type cannulation procedure in which a provider inserts one end of a cannula into a vein and the other end into an artery to create vascular access for hemodialysis. The procedure enables a dialysis machine to remove waste, salt, and excess fluid from the blood and return purified blood to the patient.
Service Type: Vascular access procedure for hemodialysis
Typical Site of Service: Outpatient vascular procedure area, dialysis center, or ambulatory surgery setting
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with end-stage renal disease (ESRD) requiring chronic hemodialysis presents for creation of an external Scribner-type arteriovenous shunt (external cannulation connecting a vein to an artery). The procedure is scheduled in an outpatient vascular access procedure room or ambulatory surgery center under local anesthesia and conscious sedation. Pre-procedure workflow includes vascular mapping, consent, assessment of infection risk, and review of anticoagulation. The provider identifies suitable vessels, creates the external cannulation with the cannula tunneled and secured, confirms flow and hemostasis, and provides post-procedure instructions including exit-site care and dialysis scheduling. Typical sites of service are hospital outpatient department, ambulatory surgery center, or freestanding dialysis access center. The patient typically returns to the dialysis unit for first use after assessment for adequate flow and absence of bleeding or infection; follow-up includes access surveillance and wound checks.
