About the C81 Code Range
The ICD-10-PCS root operation Planar Nuclear Medicine Imaging (code C81) refers to diagnostic imaging using radionuclides to capture two-dimensional images of specific body parts. In the Nuclear Medicine section, this procedure is often applied to the Eye and related structures.
This operation uses radioactive substances to visualize functional information in tissues, such as the bilateral lacrimal ducts or the eye itself. For example, code C8191ZZ denotes planar nuclear medicine imaging of the bilateral lacrimal ducts performed with Technetium 99m (Tc-99m), a commonly used radionuclide. Alternatively, codes C819YZZ and C81YYZZ capture similar imaging procedures using other radionuclides. Utilizing these detailed nuclear medicine imaging codes ensures precise documentation of diagnostic tests that assess functional aspects of eye-related anatomy.
