About CG11SZZ
CG11SZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the parathyroid glands using a thallium 201 (tl-201) 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).
The same procedure with a different approach is coded CG111ZZ (technetium 99m (tc-99m)) 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.
