About CW16SZZ

CW16SZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the chest and neck 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 CW10SZZ (abdomen), CW11SZZ (abdomen and pelvis), CW13SZZ (chest), CW14SZZ (chest and abdomen), CW1BSZZ (head and neck), CW1DSZZ (lower extremity) and 3 more.

The same procedure with a different approach is coded CW161ZZ (technetium 99m (tc-99m)), CW16DZZ (indium 111 (in-111)), CW16FZZ (iodine 123 (I-123)), CW16GZZ (iodine 131 (I-131)), CW16LZZ (gallium 67 (ga-67)) and CW16YZZ (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.
