CPT code 93986 denotes a duplex ultrasound of arterial and venous structures in one upper extremity performed to assess vascular supply and venous return before establishing hemodialysis access. This diagnostic imaging code is important nationally because it directly supports vascular access planning, which affects dialysis outcomes, surgical decision-making, and care coordination for patients with advanced kidney disease.

Key payers typically involved in coverage and payment discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing orientation to the service, national relevance for vascular access planning, and an overview of the types of benchmarks and policy topics that commonly accompany analysis of this code, including utilization patterns, site-of-service considerations, and payer coverage trends. The publication also summarizes expected documentation elements, common clinical indications for use, and areas where policy updates or guideline alignment can influence payment and access.

Data not available in the input is noted where specific payer rates, associated taxonomies, ICD-10 mappings, and related codes would normally be provided.
