About the CT Body System
These nuclear medicine procedures introduce radioactive materials to examine the urinary system or study body fluids and blood elements.
Planar imaging produces single-plane pictures from radioactive emissions. Tomographic imaging produces three-dimensional pictures, while nonimaging assays detect emissions to study body fluids and blood elements. The body-part values are Kidneys, Ureters and Bladder; Bladder and Ureters; and Urinary System.
Questions About This Page
How many codes are in the CT body system?
The CT body system contains 19 ICD-10-PCS codes in FY 2027, organized into 3 root operations. 16 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.
