About DU12B7Z

DU12B7Z is the ICD-10-PCS code for a brachytherapy procedure on the uterus using a low dose rate (LDR) approach with cesium 137 (cs-137) (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 DU10B7Z (ovary) and DU11B7Z (cervix).

The same procedure with a different approach is coded DU1297Z (high dose rate (HDR)).

With a different device, use DU12B6Z (cesium 131 (cs-131)), DU12B8Z (iridium 192 (ir-192)), DU12B9Z (iodine 125 (I-125)), DU12BBZ (palladium 103 (pd-103)), DU12BCZ (californium 252 (cf-252)) and DU12BYZ (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.
