About DT10B9Z

DT10B9Z is the ICD-10-PCS code for a brachytherapy procedure on the kidney using a low dose rate (LDR) approach with iodine 125 (I-125) (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 DT11B9Z (ureter), DT12B9Z (bladder) and DT13B9Z (urethra).

The same procedure with a different approach is coded DT1099Z (high dose rate (HDR)).

With a different device, use DT10B6Z (cesium 131 (cs-131)), DT10B7Z (cesium 137 (cs-137)), DT10B8Z (iridium 192 (ir-192)), DT10BBZ (palladium 103 (pd-103)), DT10BCZ (californium 252 (cf-252)) and DT10BYZ (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.
