About the CT1 Code Range
The ICD-10-PCS root operation Planar Nuclear Medicine Imaging (code category CT1) refers to obtaining flat, two-dimensional images using radioactive substances to evaluate the function and structure of organs. This procedure is particularly applied within the Nuclear Medicine classification to assess various parts of the Urinary System.
Planar Nuclear Medicine Imaging involves administering radionuclides like Technetium 99m (Tc-99m), Iodine 123 (I-123), or Iodine 131 (I-131) to visualize organs such as the Kidneys, Ureters, and Bladder. The provided codes, including CT131ZZ for Tc-99m imaging and CT13FZZ for I-123 imaging, specify the radionuclide used and the exact urinary structures examined. Alternative radionuclides are also coded, as seen in CT13YZZ and CT1YYZZ, allowing precise documentation of the imaging modality. These codes help accurately represent diagnostic nuclear medicine procedures targeting urinary organs in a planar format.
Questions About This Page
How many billable codes are in the CT1 range?
Of the 8 codes in this range, 7 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.
What does the CT1 range classify?
The range classifies Planar Nuclear Medicine Imaging procedures, introduction of radioactive materials into the body for single plane display of images developed from the capture of radioactive emissions, performed on the urinary system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
