About the CH1 Code Range
The ICD-10-PCS root operation Planar Nuclear Medicine Imaging (CH1) refers to the use of nuclear medicine techniques to produce two-dimensional images of body tissues. This procedure typically involves administering radionuclides and capturing planar images to evaluate the structure and function of specific body parts.
Within the Nuclear Medicine classification, Planar Nuclear Medicine Imaging is frequently applied to the Skin, Subcutaneous Tissue, and Breast. The coding examples demonstrate how this imaging can be targeted to the Right Breast, Left Breast, or Bilateral Breasts using various radionuclides such as Technetium 99m (Tc-99m), Thallium 201 (Tl-201), or other radionuclides. For instance, code CH101ZZ represents planar imaging of the right breast using Tc-99m, while CH11SZZ indicates the same procedure for the left breast using Tl-201. This specificity in coding ensures precise documentation of the imaging site and radionuclide used, which is essential for accurate clinical records and billing purposes.
