CPT code 76770 and 76775 are both used for ultrasound screenings for abdominal aortic aneurysm (AAA) in men who are 65 years of age or older. However, they have some differences in terms of the scope and extent of the ultrasound examination.
CPT code 76770 refers to a complete retroperitoneal ultrasound. This means that the ultrasound examination will encompass a comprehensive evaluation of the entire retroperitoneal space, which includes structures such as the kidneys, liver, pancreas, and aorta. The ultrasound technician will use a transducer to obtain images of these structures and assess their size, shape, and any abnormalities. This code is typically used when a more detailed and thorough examination of the retroperitoneal space is required.
On the other hand, CPT code 76775 refers to a limited retroperitoneal ultrasound. This means that the ultrasound examination will focus specifically on the aorta and surrounding structures. The technician will use a transducer to obtain images of the aorta and measure its diameter to screen for the presence of an aneurysm. This code is typically used when a targeted evaluation of the aorta is needed, without a comprehensive assessment of other retroperitoneal structures.
CPT code 76770 is used for a complete retroperitoneal ultrasound that includes an evaluation of the entire retroperitoneal space, while CPT code 76775 is used for a limited retroperitoneal ultrasound that specifically focuses on the aorta and surrounding structures. The choice of code will depend on the clinical indication and the extent of the ultrasound examination required for the patient.
