About CG12YZZ

CG12YZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the thyroid gland using an other radionuclide 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 thyroid scan and radioisotope function studies, the ICD-9-CM procedure title it maps to (92.01).

For a different body part, codes include CG11YZZ (parathyroid glands), CG14YZZ (bilateral adrenal glands) and CG1YYZZ (endocrine system).

The same procedure with a different approach is coded CG121ZZ (technetium 99m (tc-99m)), CG12FZZ (iodine 123 (I-123)) and CG12GZZ (iodine 131 (I-131)).

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.
