About C23GKZZ

C23GKZZ is the ICD-10-PCS code for a positron emission tomographic (PET) imaging procedure on the myocardium using a fluorine 18 (F-18) approach with none (qualifier: none). In ICD-10-PCS, positron emission tomographic (PET) imaging means introduction of radioactive materials into the body for three dimensional display of images developed from the simultaneous capture, 180 degrees apart, 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 C23GMZZ (oxygen 15 (O-15)), C23GQZZ (rubidium 82 (rb-82)), C23GRZZ (nitrogen 13 (N-13)) and C23GYZZ (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.
