Gastrointestinal System (CD) ICD-10-PCS
The CD body system covers Nuclear Medicine procedures on gastrointestinal system, with 26 ICD-10-PCS codes across 2 root operations, 22 of them billable in fiscal year 2026. Each root operation defines a distinct procedural objective, and the info icons show the official definition with a preview of the codes inside.

About the CD Body System
The ICD-10-PCS root operation for the Gastrointestinal System in the Nuclear Medicine section refers to imaging procedures that use radioactive materials to visualize internal organs. These procedures are coded under operation CD, which involves diagnostic imaging based on radioactive emissions.
Specifically, Planar Nuclear Medicine Imaging (code CD1) introduces radioactive substances into the body to produce single-plane images of the gastrointestinal structures by capturing emissions from the radioisotopes. In contrast, Tomographic Nuclear Medicine Imaging (code CD2) uses similar radioactive materials but provides three-dimensional images, offering more detailed views of the gastrointestinal system. These techniques facilitate precise diagnostics by highlighting functional aspects in addition to anatomy. Proper use of these ICD-10-PCS nuclear medicine codes ensures accurate documentation of advanced imaging studies within the gastrointestinal body system.
Questions About This Page
How many codes are in the CD body system?
The CD body system contains 26 ICD-10-PCS codes in FY 2026, organized into 2 root operations. 22 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.
