About CH11YZZ

CH11YZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the left breast using an other radionuclide 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 CH10YZZ (right breast), CH12YZZ (bilateral breasts) and CH1YYZZ (skin, subcutaneous tissue and breast).

The same procedure with a different approach is coded CH111ZZ (technetium 99m (tc-99m)) and CH11SZZ (thallium 201 (tl-201)).

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.
