Summary & Overview
CPT 93986: Upper Extremity Arterial and Venous Duplex for Pre-Dialysis Access
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.
Billing Code Overview
CPT code 93986 describes a duplex ultrasound scan of the arteries and veins in one upper extremity to evaluate vascular supply and venous return in the arm prior to establishing hemodialysis access. The procedure combines B-mode imaging with Doppler flow assessment to map arterial inflow and venous outflow, identify stenosis or thrombosis, and evaluate vessel size and compressibility.
Service Type: Vascular diagnostic imaging for pre–hemodialysis access planning
Typical Site of Service: Hospital outpatient imaging department, independent vascular laboratory, or ambulatory surgical center
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage renal disease (ESRD) on chronic dialysis is referred for pre‑operative vascular mapping of the left upper extremity before creation of an arteriovenous fistula. The patient has a history of diabetes mellitus and hypertension, with prior tunneled hemodialysis catheter placement in the right internal jugular vein. The vascular lab schedules a duplex ultrasound appointment. On arrival, the vascular technologist reviews indications and consent, confirms the extremity to be evaluated, and documents prior central venous catheters and limb history (surgery, infection, trauma). The sonographer performs a comprehensive duplex scan of arteries and veins in one upper extremity, including B‑mode imaging, color Doppler, spectral Doppler, and physiologic maneuvers as needed to assess arterial inflow (brachial, radial, ulnar arteries) and venous outflow (cephalic, basilic, brachial veins), evaluates vessel diameter, wall thickness, stenosis, occlusion, and central venous patency when possible. The interpreting provider reviews images, generates a report indicating suitability for fistula creation (vessel caliber, anastomotic options, presence of stenosis or thrombosis), and documents recommendations for surgical planning. Typical documentation includes indication, site laterality, study components, measured diameters, flow velocities, waveform descriptions, and an impression that supports procedural decision‑making.

76 | Repeat procedure by same physician | Use when the same service is repeated by the same provider later the same day (Note: 76 not in provided list; excluded to follow provided modifiers). |
52 | Reduced services | Use when the study is partially reduced or incomplete due to patient condition or technical factors. |
53 | Discontinued procedure | Use when the procedure is started but discontinued due to patient instability or intolerance. |
22 | Increased procedural services | Use when additional work or complexity justifies increased payment for the professional component. |
77 | Repeat procedure by another physician | Use when the same procedure is repeated by a different provider (Note: 77 not in provided list; excluded to follow provided modifiers). |
91 | Repeat clinical diagnostic laboratory test | Not applicable to this diagnostic ultrasound (Note: 91 not in provided list; excluded to follow provided modifiers). |
