ICD-10-PCS C91 Nuclear Medicine: Ear, Nose, Mouth and Throat Planar Nuclear Medicine Imaging

The ICD-10-PCS root operation Planar Nuclear Medicine Imaging (Code C91) involves capturing two-dimensional images of specific body regions using radionuclides. This procedure is classified under the Nuclear Medicine section and focuses on functional imaging rather than direct visualization.

Planar Nuclear Medicine Imaging is applied to the Ear, Nose, Mouth, and Throat area to assess physiological processes or detect abnormalities by tracing radioactive substances within tissues. The included codes such as C91B1ZZ and C91BYZZ demonstrate imaging of the bilateral salivary glands with different radionuclides like Technetium 99m (Tc-99m) or other radioisotopes. Additionally, C91YYZZ covers planar imaging of the entire Ear, Nose, Mouth and Throat region using other radionuclides. These codes capture the diagnostic approach used in nuclear medicine to evaluate functional anatomy by measuring the distribution of radioactive tracers in the head and neck region, aiding clinical decision-making.

List of ICD-10-PCS codes used to specify C91 - Planar Nuclear Medicine Imaging (introduction of radioactive materials into the body for single plane display of images developed from the capture of radioactive emissions). There are a total of 4 procedure codes in this section.

• C91 - Nuclear Medicine, Ear, Nose, Mouth and Throat, Planar Nuclear Medicine Imaging

• C91B1ZZ - Planar Nuclear Medicine Imaging of Bilateral Salivary Glands using Technetium 99m (Tc-99m)

• C91BYZZ - Planar Nuclear Medicine Imaging of Bilateral Salivary Glands using Other Radionuclide

• C91YYZZ - Planar Nuclear Medicine Imaging of Ear, Nose, Mouth and Throat using Other Radionuclide
