About the CD Body System
These codes describe images of the upper gastrointestinal tract, gastrointestinal tract, or digestive system made after radioactive materials enter the body.
Planar imaging uses captured radioactive emissions to display images in a single plane. Tomographic imaging uses them to display three-dimensional images.
Questions About This Page
How many codes are in the CD body system?
The CD body system contains 13 ICD-10-PCS codes in FY 2027, organized into 2 root operations. 11 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.
