About CW2DFZZ

CW2DFZZ is the ICD-10-PCS code for a tomographic (tomo) nuclear medicine imaging procedure on the lower extremity using an iodine 123 (I-123) 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 CW20FZZ (abdomen), CW21FZZ (abdomen and pelvis), CW23FZZ (chest), CW24FZZ (chest and abdomen), CW26FZZ (chest and neck), CW2BFZZ (head and neck) and 2 more.

The same procedure with a different approach is coded CW2D1ZZ (technetium 99m (tc-99m)), CW2DDZZ (indium 111 (in-111)), CW2DGZZ (iodine 131 (I-131)), CW2DKZZ (fluorine 18 (F-18)), CW2DLZZ (gallium 67 (ga-67)), CW2DSZZ (thallium 201 (tl-201)) 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.
