About C21GSZZ
C21GSZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the myocardium 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 cardiovascular and hematopoietic scan and radioisotope function study, the ICD-9-CM procedure title it maps to (92.05).
The same procedure with a different approach is coded C21G1ZZ (technetium 99m (tc-99m)), C21GDZZ (indium 111 (in-111)), C21GYZZ (other radionuclide) and C21GZZZ (none).
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.
