what does it mean by having ultrasound of both lower extremities

re: what does it mean by having ultrasound of both lower extremities

A complete ultrasound examination of an extremity (76881) consists of real time scans of a specific joint that includes examination of the muscles, tendons, joint, other soft tissue structures, and any identifiable abnormality.

A limited examination of an extremity (76882) that would be performed primarily for evaluation of muscles, tendons, joints, and/or soft tissues. This is a limited examination of the extremity where a specific anatomic structure such as a tendon or muscle is assessed.

Depends on documentation.
