About the CW1 Code Range

These procedures introduce radioactive material into the body and capture its emissions to make images displayed in a single plane.

The fourth character identifies the area imaged, such as the chest, multiple regions or the whole body. The fifth records a radionuclide, with choices including Technetium 99m, Iodine 123, Other Radionuclide and None. The sixth and seventh characters both have None as their only qualifier.

Questions About This Page

How many billable codes are in the CW1 range?

Of the 74 codes in this range, 73 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 CW1 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 anatomical regions. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
