About C2161ZZ

C2161ZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the heart, right and left 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 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 C21G1ZZ (myocardium).

The same procedure with a different approach is coded C216YZZ (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.
