CPT 93975 Duplex Ultrasound Reimbursement

Headline: CPT code 93975: Complete Duplex Ultrasound of Abdominal/Pelvic/Scrotal/Retroperitoneal Organs

Lead: CPT code 93975 denotes a complete duplex ultrasound examination of the abdominal, pelvic, scrotal, or retroperitoneal organs focused on assessing arterial supply and venous return. This diagnostic vascular imaging code is used across hospital outpatient departments, imaging centers, and vascular laboratories and plays a key role in evaluating organ perfusion, vascular pathology, and preoperative assessment.

Why it matters: Nationally, CPT code 93975 supports critical diagnostic workflows for patients with suspected vascular compromise, varicocele, testicular torsion sequelae, abdominal organ ischemia, and other vascular conditions. Accurate coding influences clinical documentation, billing compliance, and appropriate utilization of high-value imaging resources.

Payers covered: Analysis typically includes major national payers such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

What readers will learn: The publication provides benchmarks for utilization and reimbursement patterns, clinical context for appropriate use of a complete abdominal/pelvic/scrotal duplex ultrasound, and summaries of common billing considerations. It highlights typical sites of service and the diagnostic intent of the code. Data limitations: Data not available in the input are noted where applicable.

Billing Code Overview

CPT code 93975 describes a complete duplex ultrasound study of the abdominal, pelvic, scrotal, or retroperitoneal organs performed to evaluate arterial supply and venous return. The procedure combines real-time B-mode imaging with Doppler and duplex assessment to characterize vascular anatomy and flow to and from the organs in the specified regions.

Service Type: Diagnostic vascular ultrasound — complete study of abdominal/pelvic/scrotal/retroperitoneal organs

Typical Site of Service: Hospital outpatient department, radiology/vascular laboratory, or ambulatory imaging center

Clinical Context

A 58-year-old male presents to the vascular lab with several weeks of intermittent right upper quadrant abdominal pain, a palpable abdominal mass, and abnormal liver function tests. The primary care physician orders a complete abdominal and retroperitoneal duplex ultrasound to evaluate arterial perfusion and venous return to the liver, kidneys, spleen, and pelvic organs. The vascular sonographer performs a comprehensive duplex study including gray-scale imaging, color Doppler, and spectral Doppler of the abdominal aorta, renal arteries, hepatic vasculature, portal system, inferior vena cava, and pelvic venous structures. Images and velocity measurements are documented. The interpreting physician (vascular medicine or radiology) reviews the study, provides a written report describing findings such as stenosis, occlusion, aneurysm, portal hypertension, or venous thrombosis, and advises correlation with clinical and laboratory data. The study is typically performed in an outpatient vascular laboratory or hospital imaging department and is coded using 93975 for a complete duplex evaluation of abdominal, pelvic, scrotal, and/or retroperitoneal organs focusing on vascular supply and venous return.
