About the C03 Code Range
PET imaging introduces radioactive material into the body and captures its emissions to make images with depth of the brain or central nervous system.
The body part character distinguishes Brain from Central Nervous System. The radionuclide character identifies Carbon 11 (C-11), Fluorine 18 (F-18), Oxygen 15 (O-15), or Other Radionuclide. Both qualifier characters are None.
Questions About This Page
How many billable codes are in the C03 range?
Of the 6 codes in this range, 5 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 C03 range classify?
The range classifies Positron Emission Tomographic (PET) Imaging procedures, introduction of radioactive materials into the body for three dimensional display of images developed from the simultaneous capture, 180 degrees apart, of radioactive emissions, performed on the central nervous system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
