About CG111ZZ
CG111ZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the parathyroid glands using a technetium 99m (tc-99m) 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 parathyroid scan, the ICD-9-CM procedure title it maps to (92.13).
For a different body part, codes include CG121ZZ (thyroid gland).
The same procedure with a different approach is coded CG11SZZ (thallium 201 (tl-201)) and CG11YZZ (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.
