About the C23 Code Range
These procedures introduce radioactive material to create three-dimensional PET images of the heart or myocardium, the heart muscle. The images come from radioactive emissions captured simultaneously from opposite sides.
The fourth character identifies Myocardium or Heart. The fifth identifies the radionuclide: Fluorine 18 (F-18), Oxygen 15 (O-15), Rubidium 82 (Rb-82), Nitrogen 13 (N-13), or Other Radionuclide. The sixth and seventh characters each have None as their qualifier.
Questions About This Page
How many billable codes are in the C23 range?
Of the 7 codes in this range, 6 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 C23 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 heart. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
