Nuclear Medicine Terms

Get definitions for terms found in the Nuclear Medicine section used in ICD-10-PCS procedure codes. These definitions may also provide additional explanation or examples in their use.

Nuclear medicine section codes represent procedures that introduce radioactive material into the body in order to create an image, to diagnose and treat pathologic conditions, or to assess metabolic functions. The nuclear medicine section does not include the introduction of encapsulated radioactive material for the treatment of cancer. These procedures are included in the radiation oncology section. Nuclear medicine procedure codes have a first character value of “C”. The second character specifies the body system on which the nuclear medicine procedure is performed. The third character root type indicates the type of nuclear medicine procedure (e.g., planar imaging or non-imaging uptake).

Terms to Type

Nonimaging Nuclear Medicine Assay
Introduction of radioactive materials into the body for the study of body fluids and blood elements, by the detection of radioactive emissions
Nonimaging Nuclear Medicine Probe
Introduction of radioactive materials into the body for the study of distribution and fate of certain substances by the detection of radioactive emissions; or, alternatively, measurement of absorption of radioactive emissions from an external source
Nonimaging Nuclear Medicine Uptake
Introduction of radioactive materials into the body for measurements of organ function, from the detection of radioactive emissions
Planar Nuclear Medicine Imaging
Introduction of radioactive materials into the body for single plane display of images developed from the capture of radioactive emissions
Positron Emission Tomographic (PET) Imaging
Introduction of radioactive materials into the body for three dimensional display of images developed from the simultaneous capture, 180 degrees apart, of radioactive emissions
Systemic Nuclear Medicine Therapy
Introduction of unsealed radioactive materials into the body for treatment
Tomographic (Tomo) Nuclear Medicine Imaging
Introduction of radioactive materials into the body for three dimensional display of images developed from the capture of radioactive emissions
