About the C25 Code Range
The ICD-10-PCS root operation Nonimaging Nuclear Medicine Probe (Code C25) involves performing a nuclear medicine procedure using a probe that detects radiopharmaceutical activity without producing an image. This operation is classified under the Nuclear Medicine section and focuses on monitoring physiological function.
This method is utilized for diagnostic purposes, particularly assessing the function of the Heart by detecting emitted radiation from radionuclides within the organ. Examples include codes such as C2561ZZ, which specifies a nonimaging nuclear medicine probe of the right and left heart using Technetium 99m (Tc-99m), a common radionuclide. Other codes, like C256YZZ and C25YYZZ, represent the use of different radionuclides for the same nonimaging cardiac evaluation. These nonimaging nuclear medicine probe codes enable precise coding for functional cardiac studies without anatomical imaging, providing critical information for patient diagnosis and management.
Questions About This Page
How many billable codes are in the C25 range?
Of the 4 codes in this range, 3 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.
What does the C25 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 heart. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
