About the CD2 Code Range
Tomographic (Tomo) Nuclear Medicine Imaging (root operation code CD2) involves creating detailed three-dimensional images of a body system using nuclear medicine techniques. This method provides functional imaging by detecting radionuclide tracers within the body.
Within the Nuclear Medicine classification, this root operation is applied specifically to the Gastrointestinal and Digestive systems. The provided ICD-10-PCS codes highlight how different radionuclides are used during imaging, such as Technetium 99m (Tc-99m) (CD271ZZ), Indium 111 (In-111) (CD27DZZ), or other radionuclides (CD27YZZ and CD2YYZZ). These tomographic scans capture precise functional information about the gastrointestinal tract, aiding diagnosis and treatment planning. Accurate use of these codes ensures proper documentation of the type of radionuclide used and the imaging focus within nuclear medicine procedures.
