About DD12BCZ

DD12BCZ is the ICD-10-PCS code for a brachytherapy procedure on the duodenum using a low dose rate (LDR) approach with californium 252 (cf-252) (qualifier: none).

In plain terms, this corresponds to Radioisotopic teleradiotherapy, the ICD-9-CM procedure title it maps to (92.23).

For a different body part, codes include DD10BCZ (esophagus), DD11BCZ (stomach), DD13BCZ (jejunum), DD14BCZ (ileum), DD15BCZ (colon) and DD17BCZ (rectum).

The same procedure with a different approach is coded DD129CZ (high dose rate (HDR)).

With a different device, use DD12B6Z (cesium 131 (cs-131)), DD12B7Z (cesium 137 (cs-137)), DD12B8Z (iridium 192 (ir-192)), DD12B9Z (iodine 125 (I-125)), DD12BBZ (palladium 103 (pd-103)) and DD12BYZ (other isotope).

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.
