About the CB2 Code Range
These procedures introduce radioactive material into the body and capture its emissions to create three-dimensional images of the lungs and bronchi or respiratory system.
The fourth character distinguishes Lungs and Bronchi from Respiratory System. The fifth identifies the radioactive material: Technetium 99m (Tc-99m), Krypton (Kr-81m), or Other Radionuclide. The sixth and seventh characters both have the qualifier None.
