About the CW5 Code Range
These nonimaging procedures detect radiation without making images. They track radioactive material introduced into the body or measure absorption of radiation from an external source.
The fourth character identifies the area examined: abdomen, chest, head and neck, pelvic region, or upper or lower extremity. It also distinguishes combined areas: abdomen and pelvis, chest and abdomen, or chest and neck. The fifth character identifies Technetium 99m, Indium 111, or Other Radionuclide. The sixth and seventh characters both have the qualifier None.
Questions About This Page
How many billable codes are in the CW5 range?
Of the 28 codes in this range, 27 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 CW5 range classify?
The range classifies Nonimaging Nuclear Medicine Probe procedures, introduction of radioactive materials into the body for the study of distribution and fate of certain substances by the detection of radioactive emissions; or, alternatively, measurement of absorption of radioactive emissions from an external source, 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.
