Summary & Overview
CPT 01844: Anesthesia for Vascular Shunt Creation or Revision
CPT code 01844 denotes anesthesia services provided for vascular shunt procedures, including creation or revision of shunts commonly used for dialysis access. This code is used nationally to capture anesthesia professional work associated with operative management of patients receiving shunt placement or shunt revision. Accurate use of 01844 matters for clinical documentation, billing compliance, and appropriate payment for anesthesia time and complexity tied to vascular access surgeries.
Key payers considered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context and service setting for 01844, a summary of which payers cover the service, and what typical billing considerations are involved. Where available, the publication provides benchmark information and policy updates that affect anesthesia billing for vascular shunt procedures, highlights documentation elements that support the code, and outlines common modifiers associated with anesthesia services.
This national-level summary is intended for clinicians, billing professionals, and policy analysts seeking a clear, practical briefing on CPT code 01844 and its role in perioperative anesthesia billing for vascular shunt creation and revision.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage renal disease on hemodialysis is scheduled for revision of a malfunctioning arteriovenous (AV) graft/shunt. The patient presents with recurrent thrombosis and poor dialysis flow despite prior interventions. Preoperative evaluation by the anesthesia team documents significant cardiovascular comorbidity (controlled hypertension, ischemic heart disease), and the patient is staged as an ASA P3. The procedure is performed in an outpatient ambulatory surgery center or hospital operating room under monitored anesthesia care or general anesthesia depending on clinical status and surgeon preference. Intraoperative tasks include vascular exposure, thrombectomy, patch angioplasty or synthetic graft revision, achievement of hemostasis, and assessment of flow. Postoperative transfer to the PACU follows standard monitoring for airway, hemodynamics, and vascular access function. Typical documentation includes preoperative assessment, intraoperative anesthetic record with agents and monitoring, any anesthetic complications, and disposition note confirming stable transfer and functioning dialysis access or plan for further intervention.
