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.
