About the C71 Code Range
The ICD-10-PCS root operation Planar Nuclear Medicine Imaging (Code C71) involves the use of nuclear medicine techniques to create two-dimensional images of the lymphatic and hematologic system. This procedure helps visualize the function and structure of lymph nodes, spleen, bone marrow, and blood as part of diagnostic evaluation.
This classification under Nuclear Medicine uses various radionuclides to capture images via planar (flat) nuclear imaging. For example, codes differentiate imaging by body part and radionuclide used: Bone Marrow imaging with Technetium 99m (Tc-99m) (code C7101ZZ) or Indium 111 (In-111) (code C710DZZ), Spleen imaging with Tc-99m (code C7121ZZ), and Blood imaging with In-111 (code C713DZZ). Additionally, lymphatic regions like Head and Neck or Pelvic Lymphatics are imaged with several radionuclide options to tailor the diagnostic approach. Accurately coding these planar nuclear medicine studies is essential for documenting the specific anatomical site and radionuclide used in imaging the lymphatic and hematologic systems.
