CPT code 76776 denotes a diagnostic ultrasound of transplanted kidney(s) with color (duplex) Doppler imaging to assess graft anatomy and blood flow. This study is a core imaging modality in transplant follow-up and acute graft evaluation, providing noninvasive assessment of vascular patency, perfusion, and intrarenal blood flow. Nationally, accurate coding and appropriate use of this service influence utilization metrics, post-transplant surveillance protocols, and imaging workflow at transplant centers and outpatient radiology settings.

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 service settings, common billing modifiers and administrative considerations provided separately, and context on how this code fits into transplant imaging pathways. The publication outlines benchmarking and reimbursement considerations, payer coverage patterns, and operational implications for imaging departments and transplant programs. It also highlights policy updates or coding guidance when available and clarifies where input data is missing. The focus remains national and clinical-administrative: helping coders, billing managers, and health system leaders understand the role and reporting of CPT code 76776 in transplant care.
