About DT129YZ

DT129YZ is the ICD-10-PCS code for a brachytherapy procedure on the bladder using a high dose rate (HDR) approach with other isotope (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 DT109YZ (kidney), DT119YZ (ureter) and DT139YZ (urethra).

The same procedure with a different approach is coded DT12BYZ (low dose rate (LDR)).

With a different device, use DT1297Z (cesium 137 (cs-137)), DT1298Z (iridium 192 (ir-192)), DT1299Z (iodine 125 (I-125)), DT129BZ (palladium 103 (pd-103)) and DT129CZ (californium 252 (cf-252)).

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.
