About CW1BGZZ

CW1BGZZ is the ICD-10-PCS code for a planar nuclear medicine imaging procedure on the head and neck using an iodine 131 (I-131) 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 CW10GZZ (abdomen), CW11GZZ (abdomen and pelvis), CW13GZZ (chest), CW14GZZ (chest and abdomen), CW16GZZ (chest and neck), CW1DGZZ (lower extremity) and 3 more.

The same procedure with a different approach is coded CW1B1ZZ (technetium 99m (tc-99m)), CW1BDZZ (indium 111 (in-111)), CW1BFZZ (iodine 123 (I-123)), CW1BLZZ (gallium 67 (ga-67)), CW1BSZZ (thallium 201 (tl-201)) and CW1BYZZ (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.
