About CW1MLZZ

CW1MLZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the upper extremity using a gallium 67 (ga-67) 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 CW10LZZ (abdomen), CW11LZZ (abdomen and pelvis), CW13LZZ (chest), CW14LZZ (chest and abdomen), CW16LZZ (chest and neck), CW1BLZZ (head and neck) and 3 more.

The same procedure with a different approach is coded CW1M1ZZ (technetium 99m (tc-99m)), CW1MDZZ (indium 111 (in-111)), CW1MFZZ (iodine 123 (I-123)), CW1MGZZ (iodine 131 (I-131)), CW1MSZZ (thallium 201 (tl-201)) and CW1MYZZ (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.
