ICD-10-PCS CT6 Nuclear Medicine: Urinary System Nonimaging Nuclear Medicine Assay

The ICD-10-PCS root operation Nonimaging Nuclear Medicine Assay (CT6) refers to diagnostic tests that assess physiological function of a body system using radionuclides without producing images. In the Nuclear Medicine section, this operation focuses on evaluating organ function chemically rather than visually.

For the Urinary System, codes like CT631ZZ describe assays using Technetium 99m (Tc-99m) to analyze the Kidneys, Ureters, and Bladder. Other radionuclides such as Iodine 123 (CT63FZZ), Iodine 131 (CT63GZZ), and Iodine 125 (CT63HZZ) are also utilized in testing organ function without imaging. The flexibility to code tests with various radionuclides, including other unspecified agents (CT63YZZ and CT6YYZZ), ensures precise documentation of the diagnostic assay performed. These nonimaging nuclear medicine assay codes enable clear communication of functional diagnostic procedures in the urinary tract within ICD-10-PCS.

List of ICD-10-PCS codes used to specify CT6 - Nonimaging Nuclear Medicine Assay (introduction of radioactive materials into the body for the study of body fluids and blood elements, by the detection of radioactive emissions). There are a total of 7 procedure codes in this section.
