About the BP4 Code Range
The ICD-10-PCS root operation Ultrasonography (code BP4) refers to imaging performed using sound waves to visualize anatomical structures, particularly bones and joints, without the use of ionizing radiation. It is part of the Imaging section, focusing on non-invasive diagnostic techniques.
This operation is commonly applied to evaluate the upper bones and related joints such as the shoulder, elbow, wrist, and hand. The provided codes demonstrate specific applications, like ultrasonography of the right shoulder (BP48ZZZ) and left wrist (BP4MZZZ). Some codes include densitometry (e.g., BP4LZZ1) to measure bone density during the ultrasound exam. These detailed ICD-10-PCS ultrasonography codes enable precise documentation of imaging procedures used for diagnosing musculoskeletal conditions in the upper extremities, supporting accurate clinical records and billing processes.
