About CW24SZZ

CW24SZZ is the ICD-10-PCS code for a tomographic (tomo) nuclear medicine imaging procedure on the chest and abdomen using a thallium 201 (tl-201) approach with none (qualifier: none). In ICD-10-PCS, tomographic (tomo) nuclear medicine imaging means introduction of radioactive materials into the body for three dimensional 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 CW20SZZ (abdomen), CW21SZZ (abdomen and pelvis), CW23SZZ (chest), CW26SZZ (chest and neck), CW2BSZZ (head and neck), CW2DSZZ (lower extremity) and 2 more.

The same procedure with a different approach is coded CW241ZZ (technetium 99m (tc-99m)), CW24DZZ (indium 111 (in-111)), CW24FZZ (iodine 123 (I-123)), CW24GZZ (iodine 131 (I-131)), CW24KZZ (fluorine 18 (F-18)), CW24LZZ (gallium 67 (ga-67)) and 1 more.

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.
