About C22GYZZ

C22GYZZ is the ICD-10-PCS code for a tomographic (tomo) nuclear medicine imaging procedure on the myocardium using an other radionuclide approach with none (qualifier: none). In ICD-10-PCS, tomographic (tomo) nuclear medicine imaging means introduction of radioactive materials into the body for three dimensional 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).

For a different body part, codes include C226YZZ (heart, right and left) and C22YYZZ (heart).

The same procedure with a different approach is coded C22G1ZZ (technetium 99m (tc-99m)), C22GDZZ (indium 111 (in-111)), C22GKZZ (fluorine 18 (F-18)), C22GSZZ (thallium 201 (tl-201)) and C22GZZZ (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.
