About the C75 Code Range
The ICD-10-PCS root operation Nonimaging Nuclear Medicine Probe (code range starting with C75) refers to the use of a nuclear medicine probe to detect physiological functions of the lymphatic and hematologic system without generating an image. This diagnostic procedure involves measuring radionuclide emissions to assess specific lymphatic regions.
This operation is classified under Nuclear Medicine and targets various lymphatic body parts such as the Head and Neck Lymphatics, Pelvic Lymphatics, Upper Chest, Trunk, and limbs including the Upper and Lower Extremities. For example, code C7551ZZ specifies probing the head and neck lymphatics using Technetium 99m (Tc-99m), while C75DYZZ indicates a similar procedure for pelvic lymphatics with other radionuclides. This detailed coding allows precise documentation of the region probed and type of radionuclide used, supporting accurate procedural reporting and clinical decision-making.
Questions About This Page
How many billable codes are in the C75 range?
Of the 18 codes in this range, 17 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 C75 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 lymphatic and hematologic system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
