About the C05 Code Range
These procedures study the brain or central nervous system without making images. They detect emissions from radioactive material introduced into the body or measure absorption of emissions from an external source.
The fourth character identifies Brain or Central Nervous System. The fifth identifies the radionuclide, a radioactive substance, as Xenon 133 (Xe-133) or Other Radionuclide. The sixth and seventh characters both have only the None qualifier.
