About CT13GZZ
CT13GZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the kidneys, ureters and bladder using an iodine 131 (I-131) approach with none (qualifier: none). In ICD-10-PCS, planar nuclear medicine imaging means introduction of radioactive materials into the body for single plane display of images developed from the capture 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).
The same procedure with a different approach is coded CT131ZZ (technetium 99m (tc-99m)), CT13FZZ (iodine 123 (I-123)) and CT13YZZ (other radionuclide).
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.
