About CT63YZZ

CT63YZZ is the ICD-10-PCS code for a nonimaging nuclear medicine assay procedure on the kidneys, ureters and bladder 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 renal scan and radioisotope function study, the ICD-9-CM procedure title it maps to (92.03).

For a different body part, codes include CT6YYZZ (urinary system).

The same procedure with a different approach is coded CT631ZZ (technetium 99m (tc-99m)), CT63FZZ (iodine 123 (I-123)), CT63GZZ (iodine 131 (I-131)) and CT63HZZ (iodine 125 (I-125)).

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.
