About the BW4 Code Range
The ICD-10-PCS root operation Ultrasonography (code BW4) refers to the imaging of anatomical regions using ultrasound technology. It is categorized under the Imaging section and involves non-invasive visualization to assist in diagnosis and treatment planning.
This operation captures ultrasound images of various body parts without exposure to radiation. Examples include Ultrasonography of the Abdomen (BW40ZZZ), which helps evaluate abdominal organs; Ultrasonography of the Abdomen and Pelvis (BW41ZZZ), combining assessment of both regions; and Ultrasonography of the Neck (BW4FZZZ), commonly used to examine thyroid or vascular structures. Additionally, Ultrasonography of the Pelvic Region (BW4GZZZ) evaluates reproductive and adjacent organs. These specific ICD-10-PCS ultrasonography codes facilitate precise documentation of ultrasound procedures aimed at different anatomical areas, ensuring clear communication of imaging services provided.
