About the BD Body System
These codes describe images of digestive areas, including the esophagus, stomach, small bowel, colon, appendix and rectum. They also include the mouth and oropharynx, the part of the throat behind the mouth.
The type character separates fluoroscopy, which displays images in real time using radiation, from CT, which builds views from multiple radiation exposures. Ultrasonography uses sound waves to show anatomy or flow in real time. The body-part character distinguishes specific sites from broader areas such as Upper GI and Gastrointestinal Tract.
Questions About This Page
How many codes are in the BD body system?
The BD body system contains 32 ICD-10-PCS codes in FY 2027, organized into 3 root operations. 29 of them are billable on inpatient claims.
What is a root operation?
The root operation is the third character of every ICD-10-PCS code and names the objective of the procedure. Drainage takes fluid out, Excision cuts out a portion of a body part, and Resection removes all of one. Picking the right root operation is the central skill of PCS coding, so each one above carries its official CMS definition.
