About the BD4 Code Range

The ICD-10-PCS root operation Ultrasonography (code BD4) refers to creating images of internal body structures using ultrasound technology. This non-invasive imaging technique is part of the Imaging section and focuses on visualizing organs within the gastrointestinal system.

Within this classification, specific codes describe ultrasonography of different gastrointestinal organs, enabling precise procedural documentation. For example, code BD41ZZZ represents an ultrasound of the Esophagus, while BD42ZZZ is used for imaging the Stomach. Additional codes include ultrasonography of the Gastrointestinal Tract (BD47ZZZ), Appendix (BD48ZZZ), Duodenum (BD49ZZZ), and Rectum (BD4CZZZ). These GI ultrasonography codes are essential for accurately capturing ultrasound procedures that aid diagnosis and patient management without invasive intervention.
