CPT code 51610 denotes urethrocystography, a diagnostic imaging procedure that involves urethral catheterization and retrograde instillation of contrast to visualize the urethra and bladder. This study is used to detect strictures, fistulae, diverticula, reflux, and other structural or functional abnormalities of the lower urinary tract. Nationally, the code is important for capturing imaging-based evaluation of urinary symptoms, preoperative assessment, and postoperative surveillance.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when the procedure is used, the typical settings where it is performed, and which payers commonly reimburse for imaging services of this type. The publication also outlines common billing considerations and modifiers used with imaging procedures (list provided), typical service lines, and related administrative notes. The content summarizes benchmarks and policy-relevant issues affecting imaging utilization and claims processing for contrast studies of the lower urinary tract, and it highlights areas where coding clarity and documentation are often needed.

This executive summary equips clinicians, coders, and policy stakeholders with a national overview of CPT code 51610, the clinical rationale for the study, payer landscape, and the types of operational and billing topics covered in the full publication.
