What 76775 covers
This study uses real-time ultrasound with image documentation to assess a limited portion of the retroperitoneum. Common focused examinations evaluate a kidney or the abdominal aorta, rather than surveying the full range of retroperitoneal structures. A sonographer typically acquires the images, and a qualified physician interprets the study. It is performed in settings such as an imaging department, hospital, or medical office.
Choose the limited code when the documented examination is focused rather than a complete retroperitoneal survey. The report should identify the structure examined, the limited scope, and the findings, with images retained as required for the study. The service may be billed globally, or split into the professional interpretation with modifier 26 and the technical service with modifier TC. CMS applies the diagnostic imaging multiple procedure reduction to both professional and technical components when applicable.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

76775 billing questions
When should 76775 be reported instead of 76770?
Report 76775 for a focused, limited retroperitoneal examination. Use 76770 when the documented study is a complete retroperitoneal survey.
How does 76775 differ from a limited abdominal ultrasound?
76775 is focused on retroperitoneal structures, such as a kidney or the abdominal aorta. A limited abdominal ultrasound, 76705, applies when the examination is directed to the abdomen rather than the retroperitoneum.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Billing without either modifier represents the global service.
What documentation supports reporting the limited code?
Document the retroperitoneal structure examined, the focused scope of the study, and the findings. Retain image documentation for the examination.
How does CMS apply the multiple procedure reduction?
The diagnostic imaging multiple procedure reduction applies to both the professional and technical components.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
