76881 Ultrasound, extremity, nonvascular, real-time with image documentation, complete
A complete ultrasound examination of an extremity 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
76882 Ultrasound, extremity, nonvascular, real-time with image documentation, limited, anatomic specific
A limited, anatomic-specific ultrasound examination is performed primarily for evaluation of muscles, tendons, joints, and/or soft tissues. It is a limited examination where a specific anatomic structure such as a tendon or muscle (or plantar fascia) is being assessed. The code would be used to evaluate a soft-tissue mass that may be present in an extremity where knowledge of its cystic or solid characteristic is needed
76942 Ultrasonic guidance for needle placement (eg. Biopsy, aspiration, injection, localization device) imaging supervision and interpretation
Abdominal ultrasound is a type of imaging test that is used to examine organs in the abdomen including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels that lead to some of these organs can also be looked at with ultrasound to:• Guide the placement of a needle or other instrument during
a biopsy.• Look for fluid buildup in the abdominal cavity. An ultrasound
also may be done to guide the needle during a procedure to remove fluid from the abdominal cavity.
