About the CG1 Code Range
These procedures introduce radioactive material into the body and capture its emissions to make a single-plane image. The image covers the parathyroid glands, thyroid gland, both adrenal glands, or the endocrine system.
The fourth character identifies the body part. The fifth identifies the radioactive material: Technetium 99m, Iodine 123, Iodine 131, Thallium 201, or Other Radionuclide. The sixth and seventh characters are both None.
Questions About This Page
How many billable codes are in the CG1 range?
Of the 11 codes in this range, 10 are billable and valid for inpatient claim submission from October 1, 2026 through September 30, 2027. Table header codes group them but cannot be reported on claims.
What does the CG1 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 endocrine system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
