Summary & Overview
CPT 93976: Limited Organ Duplex Ultrasound for Vascular Assessment
CPT code 93976 represents a duplex ultrasound of a single organ or a limited area of the abdominal, pelvic, scrotal, or retroperitoneal organs performed to evaluate arterial supply and venous return. This limited vascular imaging code is used when focused assessment of an organ’s vascular status is required rather than a full abdominal or multisite vascular study. Nationally, limited organ duplex studies support diagnosis and management of acute and chronic vascular conditions affecting abdominal and pelvic organs, scrotal pathology, and retroperitoneal processes.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and typical settings, guidance on where this service is commonly performed, and the primary billing context for focused duplex studies. The publication outlines expected service lines and operational considerations, summarizes common modifiers and coding context where available, and highlights how limited organ duplex imaging fits into broader vascular diagnostic pathways. This summary is designed for clinical coders, practice managers, and policy analysts seeking a national-level reference for CPT code 93976 without state-specific detail.
Billing Code Overview
CPT code 93976 describes a duplex ultrasound scan of a single organ or limited area of the abdominal, pelvic, scrotal, or retroperitoneal organs performed to evaluate the organ's arterial supply and venous return. The procedure combines real-time B-mode imaging with Doppler flow assessment to assess vascular patency, blood flow characteristics, and hemodynamic compromise in the targeted organ or limited anatomic region.
Service type: Diagnostic vascular imaging (limited/composite organ duplex scan)
Typical site of service: Hospital outpatient imaging departments, radiology suites, vascular laboratories, and ambulatory surgical centers
Clinical & Coding Specifications
Clinical Context
A 54-year-old male presents to the outpatient radiology suite with progressive right upper-quadrant abdominal pain, decreased appetite, and an elevated liver function panel. The referring clinician suspects an obstructive process affecting hepatic arterial inflow or portal/venous outflow to a single abdominal organ (liver). A vascular technologist or sonographer performs a targeted duplex ultrasound of the liver (single-organ duplex scan) with real-time gray-scale imaging, color Doppler, and spectral Doppler assessment of arterial and venous flow to evaluate patency, flow velocity, and evidence of thrombosis or stenosis.
Clinical workflow: The patient check-in occurs in an imaging outpatient center or hospital radiology department. The sonographer reviews indications and prior imaging, obtains verbal consent, positions the patient, and performs a focused abdominal organ duplex exam. Images and Doppler waveforms are acquired and documented. A radiologist or vascular specialist reviews images, interprets findings, and issues a formal report. Results are communicated to the referring clinician for correlation with laboratory tests and management decisions.
