About CT6YYZZ
CT6YYZZ is the ICD-10-PCS code for a nonimaging nuclear medicine assay procedure on the urinary system using an other radionuclide approach with none (qualifier: none). In ICD-10-PCS, nonimaging nuclear medicine assay means introduction of radioactive materials into the body for the study of body fluids and blood elements, by the detection of radioactive emissions.
In plain terms, this corresponds to other radioisotope function studies, the ICD-9-CM procedure title it maps to (92.09).
For a different body part, codes include CT63YZZ (kidneys, ureters and bladder).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
