About CH12SZZ

CH12SZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the bilateral breasts 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 scan of other sites, the ICD-9-CM procedure title it maps to (92.19).

For a different body part, codes include CH10SZZ (right breast) and CH11SZZ (left breast).

The same procedure with a different approach is coded CH121ZZ (technetium 99m (tc-99m)) and CH12YZZ (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.
