Headline: CPT code 76775: Limited Retroperitoneal Ultrasound for Focused Abdominal Assessment

Lead: CPT code 76775 identifies a limited retroperitoneal ultrasound used to obtain real-time imaging of specific abdominal structures—commonly the kidneys, urinary bladder, or abdominal aorta—when a focused evaluation is required. The code matters nationally as a common imaging designation for targeted diagnostic evaluation that affects clinical workflow, coding accuracy, and payment across major payers.

CPT code 76775 represents a focused, noninvasive ultrasound examination of retroperitoneal structures performed with real-time image documentation. This procedure is used when clinicians need a limited assessment rather than a complete abdominal ultrasound, supporting diagnosis of conditions such as hydronephrosis, aortic aneurysm screening or follow-up, and focal renal pathology. The code is widely used across major national payers, including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

This publication provides a national overview of coding context and clinical use. Readers will find concise benchmarks and policy-relevant details about how the code is applied clinically, common billing considerations, and how coverage practice varies among major payers. Data not available in the input for payer-specific rates, associated taxonomies, and ICD-10 pairings is noted where applicable. The focus is to clarify the clinical and billing footprint of CPT code 76775 for health system coders, revenue cycle staff, and policy analysts.
