About the CT1 Code Range
These procedures introduce radioactive material into the body to make single-plane images of the urinary system from the radiation it releases.
The fourth character distinguishes the kidneys, ureters and bladder together; the bladder and ureters together; or the urinary system. The fifth identifies the radioactive material: Technetium 99m (Tc-99m), Iodine 123 (I-123), Iodine 131 (I-131), or Other Radionuclide. The sixth and seventh characters both have only None as a qualifier.
